I saw in the inspection that most farmers are more reasonable in fertilizing, but there are also a few farmers who are not able to fertilize. Some also believe that as long as they are willing to invest in fertilizer, cotton can be high-yield, and high-fertilizer and high-yield are equated. However, they did not understand that after excessive fertilization in cotton fields, the concentration of soil solution was increased, causing reverse osmosis of the solution in the cotton seedlings, causing the cotton seedlings to die of water shortage. Excessive fertilizer in the field will lead to diapause and dead seedlings. The members of the inspection team immediately told the farmers how to reduce the damage. Among them, one of the measures is to spray cotton seedlings 2-3 times with Huimanfeng or Zhuangfuxing humic acid active liquid fertilizer 500-800 times, spray once every 7 days, because the fertilizer contains a special The active substance can activate the soil and the cotton seedlings, so that the cotton seedlings can resume normal growth and development relatively quickly.
According to the practical experience of cotton production in the end, the law should be bottom fertilizer, seedling speed, bud fertilizer stability, flower bell fat, and general application of peach fertilizer. The specific application depends on the output target set by the farmers. However, since the large-scale promotion of the insect-resistant hybrid cotton, the ratio of the nutrient element NPK should be 3:1:3. For example, if the cotton seed is set in the mu More than 300 kg, the proportion of formula fertilization can be arranged as follows: base fertilizer, 30 kg of compound fertilizer with a content of 45% per mu, 10 kg of potash; seedling fertilizer, urea application 2 times, the first time 4 kg per mu, The second time is 5 kg per mu; the bud fertilizer is 20 kg of compound fertilizer with a content of 45% per mu, 15 kg of potassium fertilizer; flower bell fertilizer, 20 kg per mu of urea; peach fertilizer, 10 kg of urea per mu. According to the results of effective nutrient conversion, 25.44 kg of pure nitrogen, 7.5 kg of phosphorus pentoxide and 22.5 kg of potassium oxide are applied, and the ratio of effective nutrients is 3.39:1.0:3.0. . In the production practice, due to different factors such as soil texture, fertility, climate, and fertilizer type, it can be easily controlled by the households due to the seedlings.
