Can rainfall be fertilized after a long drought in cotton?

In mid-August, he received an incoming call from Zhou Guifeng, a farmer friend from Yongxiu County, Jiangxi Province. He said that the five-acre state-owned cotton variety Huzao H318 planted this year has grown very well. The single plant has already had pre-fume peach and 40-50 peaches. It is because of the continuous high temperature and drought, it has some impact on the late autumn peach. In late August, a Mr. Wang from Xinyi Town, Hanchuan City, Hubei Province, called and asked how he planted 8 acres of hybrid cotton H318. The performance was very good in the early stage. About 40 peaches were planted in each plant, and it was during the summer season (August. On the 23rd) On that day, both Yongxiu County and Hanchuan City had a rainstorm. The cotton sensation was greatly eased. I also answered several similar telephones in other places. In response to this, my answer is “you can catch fertilizer.”

This year, the continuous high temperature and drought in the southern cotton area has a great impact on large-scale cotton production. The outstanding problem is that some cottons do not set up high-yield shelves, and the bolls fall off particularly severely. Generally, the shedding rate is above 30% and the high reaches 40. Above%, some flowers have been opened to the top, and peaches have also been crowned. There is no stamina, which has caused great losses for this year's cotton production. The above two farmer cotton field cotton management level is relatively high, fertilization is also more than enough, estimated from the existing peaches, it is estimated that per mu production can receive about 250 kg of seed cotton, if after the rain to strengthen management, per acre Seed cotton 300 to 350 kg is promising.

Fertilization of cotton, in the normal growth year, generally top peach fertilizer in late July to early August end. However, in the years of drought or disaster relief, according to our many years of experience and lessons in disaster management, we should adopt flexible and contingency measures to fight against the damage and reduce the loss, so as to win the cotton harvest.

In this year's continuous drought, under the environmental conditions, many farmer's cotton fields are incapable of applying fertilizer, or fertilizers applied because of water, cotton is difficult to absorb, which restricts cotton growth and development. Therefore, for a part of the cotton field with insufficient stamina, especially some cotton fields with young bells, flowers and buds, it is entirely possible to make up the application of peach fertilizer. Based on the following points: First, the effective flowering period of cotton is generally before September 8, if the temperature is high in the later period, it can be appropriately extended. The existing part of the larger buds can be fully bloomed before; the second is the late autumn peach. The effective looping period can be extended to about 60 days; Third, this time can be robbed of topdressing urea nutritional supplement cotton bolls, apply 7.5 to 10 kg per acre. Fertilizer need not worry about the growth of cotton at this time, because the direction of cotton nutrient transportation has been changed from the main stem to the cotton boll to the fruit branch. Only pay attention to three points in the fertilization operation technology: First, to grab the fertilization when grabbed; Second, it is necessary to apply fertilizer after rain, avoid rain before fertilization, to prevent urea concentrated decomposition burn cotton seedlings; Shi. In addition, 1% urea, 1%~2% potassium sulfate and 0.2%~0.3% potassium dihydrogen phosphate solution can be applied in combination with the later stage of pest control.
