The last time for most cotton farmers to topdress is usually in late July. At this time, cotton is the peak season for growth, a large number of buds, flowering, ringing, and more than two months from the harvest, requiring a large supply of nutrients. The July-September period is the rainy season in North China. There are many rains. The cotton roots are under water supersaturation for a long time. Some cottons are often flooded and suffocated, and the roots are poorly grown, resulting in the lack of nutrient absorption and supply of cotton. Buds, falling bells, yellowish premature senescence of leaves, and a large number of physiological diseases such as stem blight of red leaves. To solve the above-mentioned physiological diseases occurring in the middle and late stages of cotton, scientific and rational application of foliar fertilizer is a very effective means.
In July and August, the growth of cotton caused by heavy rain is not prosperous (the ridge cannot be closed in time), and the yellowing of the leaves may lead to insufficient nutrient supply of cotton bolls, which may cause falling buds and falling bells. At this time, if you can spray the lion horse brand "Ye Cui" (diluted 900 times) + "é“æžœç´ " (6000 times) every 10 days, a total of 2 times, can quickly turn the leaves green, thus reducing the buds Ringing phenomenon.
Second, when the cotton is caused by spraying "insecticide", "bactericide" or "hormone", the lion brand "Ye Cui" is sprayed 900 times to relieve the symptoms.
Third, when the cotton blooms in the flowering and ringing period, the ringing is serious. Spraying the lion horse brand “Huabao†(900 times) every 10 days can significantly reduce the bud bell falling off, increase the voltial peach and increase the yield. If you use "Huabao" + "Astragalus" + Ai Zengmei 3000 times with the application, it can promote cotton pollination and better anti-fall effect.
In April and August, cotton stem blight often occurs. This is a physiological disease caused by comprehensive nutrient deficiency caused by potassium deficiency, which can cause a lot of fallen leaves. At this time, spray the lion horse brand "fruit king" + "é“æžœç´ " (6000 times), a total of 2-3 times, once every 10 days, not only can control the stem blight of red leaves, but also promote the expansion of cotton bolls, increase Fiber length and can alleviate the damage of blight.
