Recently, several farmer friends who cultivate the land react to the small back basket of agricultural technology and say: brassinolide, amine fresh ester, compound nitrophenol sodium, these three of the most common and commonly used plant growth adjustment things on the market, because their effects seem to be similar or very similar, which makes many people often confused when choosing to buy and use these three things, and do not know which one to choose to use will be better. To this end, I hope that the agricultural technology basket will write a special article to make a more comprehensive comparison of the three plant growth regulators of brassinolide, amine fresh ester, and sodium compound nitrophenol, so that everyone can figure out what are the differences between the three of them, and what are their unique advantages, and then the majority of farmers and friends in the selection, purchase and use of the good to know.
Agricultural technology small back basket estimates that more than 80% of everyone has used brassinolide, amine fresh ester, compound nitrophenol sodium these three things, but it is also estimated that at least 80% of people do not understand, can not understand the difference between these three things, most people should be confused to buy, confused use.
In order to help you thoroughly understand and understand the difference between these three things, today's agricultural technology small back basket is dedicated to a comprehensive comparison of brassinolide, amine fresh ester, compound nitrophenol sodium, these three common and commonly used plant growth regulators.
First, the source of raw materials is different
Brassinolide, which belongs to the endogenous hormone substance contained in the crop plant itself, is the active substance component extracted from the plant body, while the amine fresh ester and sodium compound nitrophenol are the material components that the crop itself does not contain, and belongs to the synthetic active substance component.
Second, the appearance color is different
Brassinolide original drugs are white crystal powders in appearance, but most of the brassinolides on the market are water-soluble bottled liquids; amine fresh ester original drugs are white and white crystals in appearance, but the common state on the market is a crushed white powder; and the original sodium compound nitrophenol is orange-red crystals in appearance, but most of the common sodium nitrate phenol on the market is a crushed orange or red powder.

Third, the pH value is different in acidity and alkalinity
Brassinolide is a weak acidic substance, amine fresh ester belongs to a weak acidic substance, sodium compound nitrophenol belongs to a soft alkali substance, in most cases they can be used as neutral substances, but because the use of acidic substances and alkaline substances is easy to cause acid-base neutralization failure, so if we are particularly particular, we should try to avoid using the three with fertilizer drugs that are opposite to its acidity and alkalinity.
Fourth, the active chemical composition is different
The chemical composition of brassinolide is mainly sterols, the chemical composition of amine fresh esters is mainly sodium nitrophenol salts, and the chemical composition of sodium compound nitrophenol is mainly polyamines.

Fifth, the speed of effect is different
In terms of brassinolide, amine fresh ester, and sodium compound nitrophenolate three regulator substances, if you compare the speed of effect after their use, among the three, the effect rate after the use of amine fresh ester is the slowest, brassinolide after use between amine fresh ester and sodium compound nitrophenol, and sodium compound nitrophenol is the fastest after use, it is also recognized as one of the fastest plant growth regulators with the fastest effect rate, under the condition of temperature above 30 degrees, the fastest 24 hours can be seen.

6. The duration of the validity period is different
Brassinolide, amine fresh ester, and sodium compound nitrophenolate not only have different speeds of action, but also the duration of the drug after use is also different. In general, although the effect rate of sodium compound nitrophenolate is very fast, its continuous validity period is relatively short, and the general continuous validity period is only about 10 days, which is its disadvantage; although the effect rate of amine fresh ester is relatively slow, the continuous validity period after its use is very long, and the general duration period can be as long as 25-30 days, which is one of its advantages; and the effect speed and continuous validity period of brassinolide are centered, and its continuous validity period is generally about 15-20 days.
Seven, the applicable temperature range is different
Brassinolide, amine fresh ester, and sodium compound nitrophenol, although all three belong to the type of plant growth regulator, they have certain differences in the applicable temperature range, which will directly affect their effect after use.
In general, the most suitable range of use of brassinolide is 15-30 degrees, of which the best effect is to use about 20-25 degrees, the minimum use temperature should not be less than 5 degrees; amine fresh ester in a low temperature environment (such as spring and winter) after use than brassinolide and sodium nitrate effect is better; the minimum temperature applicable to sodium complex nitrate is 15 degrees, less than 15 degrees below may cause reduced efficacy or ineffectiveness, in the condition of about 25-28 degrees the use of the effect will be better.
Therefore, in the case of relatively low temperatures, it is better to use brassinolide or amine fresh esters, such as greenhouse crops in spring and winter, and the use of sodium compound nitrate phenol in the summer and autumn temperature seasons will play a prominent role faster and better. It should be noted that these three regulators can not be used in the time period of high temperature drought and noon strong light, and should also be avoided in a high temperature environment above 30 degrees or a low temperature environment below 10 degrees, so as to avoid the negative effect of the drug on crop growth in a high temperature environment or the effect after use is not obvious, such as drug poisoning or inhibition of normal growth or promote crop difference.
Eighth, the dosage concentration range is different
Although the three regulations of brassinolide, amine fresh ester, and sodium compound nitrophenol are good, too large or too high a concentration will cause the crop to have a toxic effect or a negative effect of inhibiting growth.
In general, the dosage concentration of brassinolide should be controlled below 0.01ppm, the dosage concentration of amine fresh ester should be mastered at about 8-15ppm, and the amount of sodium compound nitrophenol is generally mastered in the foliar spraying of about 0.2-0.5 grams per mu, and the amount of bottom fertilizer or punching is about 6-10 grams per mu.
Nine, enhance photosynthesis effect is different
After the use of brassinolide, amine fresh ester and sodium compound nitrophenol on field crops, they can effectively enhance the ability of crop photosynthesis plant organic nutrients, but the ability of the three to enhance crop photosynthesis is strong and weak.
If only from the perspective of enhancing the photosynthetic ability of crop leaves, the use of amine fresh esters and sodium compound nitrophenol has better enhancement of photosynthesis in crop leaves, and brassinolide is worse than amine fresh esters and sodium compound nitrophenol in enhancing the photosynthetic ability of crop leaves.
In this agricultural technology small back basket also to share a little trick to use: in the greenhouse with insufficient light or relatively weak lighting, the effect of choosing to use amine fresh ester or sodium compound nitrophenol is much better than using brassinolide to enhance crop photosynthesis.
X. The effect of enhancing crop stress resistance is different
Brassinolide, amine fresh ester, and sodium compound nitrophenolate, these three regulators have a certain effect on enhancing the stress resistance of crops under adverse environmental conditions, but the three are strong and weak in enhancing the stress resistance of crops.
From the perspective of the use of these three substances alone, the use of amine fresh esters has the best effect on improving crop stress resistance, sodium compound nitrophenol is in the middle of the effect on improving crop stress resistance, and brassica is the weakest and worst effect in improving crop stress resistance.
Eleven, improve the quality of production effect is different
If only from the perspective of improving the quality of crops, amine fresh esters in increasing single weight, promoting coloring, increasing sugariness, improving taste quality is the best, the role of brassica and sodium compound nitrophenol is mainly reflected in the regulation of the overall growth of crops, the role of crops to increase yield and improve quality is very insignificant.
12. The safety of use is different
Brassinolide, amine fresh ester, compound nitrophenol sodium three things, the amount of too large or too high concentration, are not conducive to the normal growth of crops, but also not conducive to the increase in crop yield and income.
Under normal circumstances, these three are in terms of the safety of crops after use, the use of amine fresh esters is the best for the safety of crops, the least likely to cause crop harm, the use of sodium compound nitrophenol is the worst, improper use is most likely to lead to crop damage (such as poisoning or inhibition of growth), and the safety of the use of brassinolide is between amine fresh esters and sodium compound nitrophenol.
13. The mechanism of action is different
Although brassinolide, amine fresh ester, and sodium compound nitrophenol are all very efficient and very easy to use broad-spectrum plant growth regulators, the drug characteristics, conditions of use and use effect of the three are very different, and this agricultural technology basket has made a comprehensive comparison for everyone above. The reason why the effect of these three things is very different is inseparable from their different drug characteristics and different mechanisms of action.
1. Brassinolide
Brassinolide, is a highly active, broad-spectrum plant endogenous hormone, it is the original substance in the crop body, its biggest feature is to protect and repair the cells of the crop, its role is mainly reflected in the regulation of nutrient distribution in the crop body and balance of a variety of hormone content in the crop body (such as gibberellin, auxin, cytokinin, etc.), in the crop growth process plays a very excellent comprehensive regulatory effect.
The functional effect of brassinolide on crops is mainly reflected in the following aspects: (1) promote the division and elongation of cells in the crop, and have the effect of enhancing nutrient supply on promoting the nutrient growth and reproductive growth of crops; (2) awaken seed dormancy, promote seed germination, and improve germination rate; (2) improve leaf hypertrophic fertilizer greenness, increase chlorophyll content in leaves, and enhance leaf photosynthesis ability; (3) promote pollen germination, promote pollen tube elongation, promote pollination fertilization, and improve flowering and fruit setting rate; (4) improve grain and fruit fruit setting rate. Increase single weight and increase yield; (5) Enhance the stress resistance of crops to adverse environments (such as drought, cold, high temperature, etc.), promote the recovery of crop victim tissue cells, and reduce or mitigate the impact of drug or fertilizer damage on crops.
2. Sodium compound nitrophenol
Sodium compound nitrophenolate, is a highly active, broad-spectrum plant growth regulator, it is essentially a powerful cell activator, its biggest feature is to quickly penetrate into the crop body to improve the activity of crop cells, its role is mainly reflected in enhancing the cell vitality of crops, improve the fluidity of cytoplasm (cell fluid) in crop cells.
The functional effect of sodium compound nitrophenolate on crops is mainly reflected in the following aspects: (1) breaking seed dormancy and promoting rapid rooting and germination of seeds; (2) improving root development, enhancing the absorption capacity of roots to water and fertilizer nutrients, and enhancing the growth and robustness of seedlings and plants; (3) enhancing the nutrients manufactured by photosynthesis to deliver more nutrients to seeds and fruit sites, that is, promoting the absorption of nutrients by crops and promoting the operation of nutrients in crops; (4) improving flowering quality, improving fruit set rate, and promoting flower and fruit full development ;(5) Enhance the stress resistance of crops through indirect action and stimulate the vigorous growth of crops.
3. Amine fresh ester
Amine fresh ester, is also a broad spectrum and the effect is very prominent plant growth regulator, its function is mainly by regulating the balance between different endogenous hormones of crops and play a prominent role, is to enhance the activity of oxidase, nitrate reductase in the crop body, and then to enhance the carbon and nitrogen metabolism function of crops, enhance the physiological metabolic capacity of crops, enhance the rate of leaf photosynthesis, enhance the nutrient supply capacity of crops, enhance the absorption capacity of root water and fertilizer, enhance the resistance of crops to adverse environments, Enhancing the antioxidant capacity of crops (delaying the aging rate of crops) and other purposes of promoting growth, increasing yield and increasing income.
Finally, the agricultural technology basket will emphasize a point for everyone: brassinolide, amine fresh ester, and sodium complex nitrophenol are only plant growth regulators, not foliar fertilizers that can directly provide nutrients to crops, so none of the three can replace foliar fertilizers or be used as foliar fertilizers.
