Potassium dihydrogen phosphate is a common chlorine-free phosphorus and potassium compound fertilizer, with high nutrient content, normal is white, soluble in water, and is known as universal fertilizer.
It has complete efficacy, can make crops cold and drought resistant, can also promote photosynthesis and metabolic processes, and can promote fruit expansion and color increase, and is widely used in the growth of various fruits, vegetables and food crops.
In the actual use process, most of the grassroots producers are accustomed to using alone, without compound habits, although it can play an effect, but it is relatively limited, and it has not been able to give full play to the fertilizer effect.
In order to achieve a single spray and achieve the management goal, it is necessary to know how to mix, and the ability to identify the common 6 mixed formulas is the key to high crop yields.
with fertilizer
The growth of crops is inseparable from fertilizer, macro, medium and trace elements are not lacking, as long as it is missing, the growth and development of plants will be hindered, and the symptoms of nutrient deficiency are obvious.
Paired with urea. Urea is a typical nitrogen fertilizer, nitrogen is missing, plant growth is stunted, the leaves are thin and few, yellow-green, until completely dry, the plant is short, the fruit is not satisfied, and it is easy to premature aging.
Moreover, it is particularly important that urea has a strong osmotic ability, which is comparable to water, can quickly penetrate the leaf cell membrane, be absorbed and utilized by plants, and the fertilizer is released quickly.
With potassium dihydrogen phosphate, foliar spraying, the faster the foliar absorption rate of the plant, the more nitrogen can be obtained by the plant, and the utilization rate of potassium dihydrogen phosphate can be improved.
With boron fertilizer. Boron is a trace element fertilizer, which can promote the transport and metabolism of carbohydrates in plants, promote cell division, promote the development of reproductive organs, and promote the nitrogen fixation ability of leguminous crops.
Mixed with potassium dihydrogen phosphate, the effect is doubled: it can promote the flower bud differentiation process of the plant, avoid flower and fruit drop and plant lodging, improve the pollination fruiting rate, improve the fruit quality, expand the fruit, increase the fruit color and sweetness.
Pair with a conditioner
Plant growth regulators are different from chemical fertilizers that only provide nutrients to promote plant growth, and they can stimulate, inhibit and promote the germination, flowering, fruit setting, ripening and shedding of crops.
With brassinolide. Brassin can promote the development of photosynthesis of plants, increase the chlorophyll content, make the root system more developed, increase the fruit setting rate, single fruit weight and improve the quality.
Mixed with potassium dihydrogen phosphate, the cold and frost resistance of the plant is improved, and the mixture can be sprayed before the spring cold and the winter cold wave before the cold wave in winter, which can enhance the drought resistance, balance the growth of the plant, and promote the absorption of nutrients.
It should be noted that the appropriate amount of top dressing should be carried out 3-5 days before spraying the mixture, because after spraying the mixture, the plant's ability to absorb nutrients from the soil will be greatly improved, and it is necessary to seize the opportunity to supplement nutrients.
Paired with quat horm. Chlormequat is a widely used plant growth regulator, which can control plant growth and enhance plant lodging resistance. It can also thicken the leaves, promote photosynthesis and improve quality; It can also improve the ability to resist drought, drought and salinity.
Mixed with potassium dihydrogen phosphate, it can control the growth of plants with severe vigor, and can also supplement phosphorus and potassium, which is conducive to leaf photosynthesis and fruit growth.
With paclobutrazol. Paclobutrazol is a systemic plant growth retardant that has been applied to the growth of crops such as apple, lychee, wheat, rice and peanuts.
Mixed with potassium dihydrogen phosphate, it can inhibit the growth of terminal buds, effectively promote flower bud differentiation, increase the number of flower buds and fruit rate, such as choosing to spray citrus trees from November to January of the following year, which can improve the amount of flowering and fruiting in spring.
With glucose
Glucose solution and potassium dihydrogen phosphate solution, combined with an appropriate amount of urea solution, can form the total nutrient solution required for plant growth.
It can increase the dry matter accumulation of crops, supplement the nitrogen, phosphorus and potassium elements required by plants, meet the nutrient needs in the growth process, and play a role in topdressing and promoting growth.
Moreover, it can also improve the stress resistance of plants, effectively prevent common diseases such as gray mold and downy mildew, inhibit the expansion of diseases, and reduce the threat of diseases to plants.
It should be noted that glucose is absorbed by the leaves of the plant very quickly, and the concentration of the solution should not be too high, and beware of spraying in high temperature days to avoid too high concentration, damage the leaves, and limit photosynthesis.
Finally, the application range and area of potassium dihydrogen phosphate are increasing year by year, and the mixture can improve the efficacy of the fertilizer, and the actual use process should be standardized and cautious to avoid wrong operation, pesticide damage, and threaten the growth of the plant.
In addition, it is also necessary to keep in mind that in the process of purchasing medicines, you should choose reliable merchants with guaranteed product quality, and don't just think about being cheap, buying cheap fake and shoddy products, and falling into the trap of merchants.
