Xiao Li was originally an ordinary melon farmer in the village. This year, he planted three acres of delicious cantaloupe as usual, and was looking forward to a bumper harvest season. However, just as the melons were about to ripen, the green melons suddenly began to turn yellow and wilt, and dense white downy mildew covered the leaves.
Xiao Li was so anxious that he hurriedly checked the soil and irrigation, but there were no problems. This meant that downy mildew had infected his melon fields.
Xiao Li immediately ran around the village to seek advice from several senior old farmers. But the methods they give have either been tried and have no effect, or they require long-term conditioning and do not work in the short term.
At the same time, downy mildew was still spreading, and Xiao Li watched the melon field he had worked so hard to grow for three months wither.
When half an acre of melon fields had been destroyed by disease and Xiao Li was almost desperate, an old farmer came to the village, who called himself Xiao Zhao. Xiao Zhao saw Xiao Li's sick melon field and took the initiative to ask him what the problem was.
Xiao Li told Xiao Zhao about his illness and the situation that he had asked for help to no avail. Xiao Zhao nodded and said, "Use brown sugar to prevent it, I'll teach you how to use it."
Xiao Li blamed him for not being able to think of this solution a few days ago, and he was grateful to Xiao Zhao for his help. He immediately bought brown sugar, did it according to the method and amount ratio that Xiao Zhao said, and began to spray the melon field.
A week later, the condition not only stopped getting worse, but also began to improve!
The prevention and control of downy mildew in the melon field was successful, and Xiao Li admired the old farmer Xiao Zhao. He began to often consult Xiao Zhao on various pest control skills. Under Xiao Zhao's guidance, Xiao Li tried to use brown sugar to enhance disease resistance on other vegetables he grows, and the results were remarkable.
For example, the viral diseases that often occur on tomatoes and peppers, Xiao Li sprayed brown sugar + urea solution before flowering according to Xiao Zhao's method, which successfully reduced the incidence of viral diseases, and the yield of tomatoes and peppers was also 10% higher than in previous years.
Next, at Xiao Zhao's suggestion, Xiao Li tried to use brown sugar on his newly planted peanuts, rape, and cotton to improve the fruit setting rate. He specially selected the critical period for flowering and fruiting of these crops and sprayed brown sugar + boric acid solution.
As a result, the yield of peanuts and cotton increased by almost 15 percent compared to last year, and the 100-grain weight of rapeseed also increased by 5 percent.
In addition to controlling pests and diseases, under the guidance of Xiao Zhao, Xiao Li also tried to use brown sugar to increase production. He sprayed a solution of brown sugar + potassium dihydrogen phosphate at the filling stage of wheat and rice he planted, and then harvested a bumper harvest 13% higher than in previous years.
In practice again and again, Xiao Li was completely impressed by the miraculous effect of brown sugar in agricultural applications. He is sincerely grateful to Xiao Zhao for his guidance and help, so that his various crops have achieved remarkable results and his income has been greatly increased.
Xiao Li's success in using brown sugar to control pests and diseases and increase production soon spread in the village. Some villagers often see that the vegetables and fruits harvested by Xiao Li are unsalable and of better quality.
Some neighbors even overheard Xiao Li discussing with Xiao Zhao the best time to spray thin brown sugar. This aroused the curiosity of other villagers. They began to gather at Xiao Li's field and asked him how he managed to make a good harvest. Xiao Li shared the use of brown sugar and precautions, as well as his own experience, with everyone without reservation.
For a time, many people in the village began to imitate Xiao Li's use of brown sugar. At first, the results were not particularly ideal, and many people did not know the amount and method of using them. Xiao Li and Xiao Zhao could only go door-to-door to guide them again.
After several adjustments, the villagers finally mastered the correct use of the technique. After this year, the number of farmers in the village using brown sugar technology continued to increase. Their crops are significantly more productive and of higher quality than those who don't use this technology. Many villagers who were originally in the cold have become well-off.
The atmosphere in the village seems to be much more lively. In retrospect, all of this transformation stemmed from Xiao Li's success in using brown sugar. Thanks to Xiao Zhao's unsparing guidance and help. Many villagers are still grateful to the two.
The reason why brown sugar can play a miraculous effect on controlling plant diseases and insects and promoting crop yield is because it is rich in nutrients and growth-promoting substances.
First of all, brown sugar contains a variety of nutrients such as sugars and amino acids. Plants can directly absorb these substances to replenish the energy and nutrients needed for growth and development, which is especially critical for grass or greenhouse vegetables at the seedling stage.
The data showed that after spraying brown sugar, the survival rate of green vegetable seedlings could be increased by 13%, and the growth rate was about a week earlier. Secondly, brown sugar is also rich in iron, zinc, manganese and other trace elements necessary for plant growth. Deficiencies in these elements can lead to symptoms such as poor plant growth and yellowing of leaves.
After supplementation, it can promote chlorophyll synthesis and enhance photosynthesis. Experiments showed that after spraying brown sugar three times, the yield per plant of tomato increased by nearly 10%.
Third, brown sugar itself and the substances produced by its metabolism have the effect of preventing fungi and viruses. For example, water cuneiform can inhibit the growth of pathogenic bacteria, and direct spraying of brown sugar on Solanaceae vegetables can reduce the incidence of anthracnose and powdery mildew by more than 35%.
Finally, brown sugar is also rich in growth-promoting substances, which can improve the stress resistance of plants and enrich the nutrient reserves of seeds. This can significantly reduce the flower and fruit drop of peanut, cotton and other crops, and increase the seed grain weight.
According to the survey, the cotton yield increase in the treated area is about 18%, and this effect lasts for 2 years. It can be seen that the reason why brown sugar has a remarkable effect in agriculture is that the scientific principles and data support are very sufficient. It can be described as a green and highly effective phytonutrient and growth regulator.
