According to more surveys in late July and many cotton districts, this year's cotton has been postponed on a regular basis, and the time spent on concentrated peaches is expected to be in mid-August, and some varieties should be postponed until late August. Therefore, this year's cotton fertilizer application is particularly important, and it is imperative. Specific to do the following points. Chongqing Pangfanyi Technology Co.,Ltd.

First, calculate the time account and benefit account. Due to the delay in the concentration of peaches this year, there is a large amount of maneuvering time for top dressing and there are many opportunities for compensation. We must not miss the opportunity of top dressing. In terms of efficiency, chasing peaches is quick and can be immediate. According to years of investigation, investing 1 yuan in fertilizers can increase income by 4-5 yuan, while investing in other links can only increase income by 2-3 yuan. Therefore, the application of peach fertilizer is the most cost-effective investment.
Second, the application of peach fertilizer is not afraid of cotton crazy. Some peasants worry that after the application of peach fertilizer, fear of causing "secondary growth" of cotton, and late-grooming, this kind of doubt is actually redundant. First, because the cotton concentrates on the peach, the nutrient transfer direction shifts from the main stem growth point to the Fruit branch sitting on the peach, the cotton bolls have the ability to withstand, will not cause "secondary growth"; the second is the flowering and ringing period, is cotton The second peak of carbon in the plant body, the decrease in nitrogen content, increased soluble sugar, the largest proportion of carbon and nitrogen, the most nutrients needed, I'm afraid of hungry seedlings, not afraid of mad long; Third, the upper and lower ventilation of cotton is good, on the peach The rate can be as high as 50% or more, more than 10% higher than the rate of peach on the lower part. With enough fertilizer, cotton can be stable and not degraded.
Third, pay attention to improve the application of peach fertilizer technology. Firstly, the concept of applying Peach fertilizer to Pushi fertilizer was renewed, and the concept of renewing the application of Peach fertilizer was adopted. Second, the application of Peach fertilizer before the beginning of autumn changed the amount of Peach fertilizer before and after the beginning of autumn, and generally applied 15 kg of urea per acre. Because the seedlings are suitable, the fertilization time is flexible; the third is to change the applicator to acupuncture, change the dry application to grab the fertilization, and timely irrigation when the drought, to adjust the water to fertilizer; Fourth, if the rainfall after fertilization, depending on the situation For the prosperous cotton seedlings, spray delayed-type plant growth regulators such as dildosine or methysidine, 4-5 grams or 16-20 milliliters per acre, and watered 40-50 kilograms. No long-term trends need to be sprayed.
