Count a few accounts and apply cotton peach fertilizer

This year, due to the recent hot and high temperature effects of the previous drought, the cotton development progress is very uneven, especially the number of peaches in cotton is very different. Planting early and well-managed cotton fields, cotton has an average of 8 to 10 early peaches, and high-yield farmers have more than 20 cotton early peaches, while the average cotton in the field has only 4~ Six.

In terms of cotton's fertility process, Daejeon cotton is now generally entering the ringing period. Recently, there have been showers or thunderstorms in different parts of the cotton area, and some have been raining heavily. It has a good effect on relieving high temperature, regulating water and regulating cotton, and it is a place where rainfall is too large. Lido has fewer disadvantages.

The concentration of cotton in the peach season is the period when cotton needs the most fertilizer. Judging from the period of cotton knot peaches, the peaches that were formed before July 15 were called Fuqiantao. The peaches that are made from July 16th to August 15th are Futao, and the peaches at the end of July are called early peaches, and the peaches from the end of July to August 15 are late peaches. The peaches that are made from August 16th to September 15th are autumn peaches. The current weather is conducive to a large number of concentrated on the peach, we should seize the opportunity to apply the peach fertilizer.

Some farmers have concerns about increasing the application of peach fertilizer. Some believe that the base fertilizer has been applied in the early stage, or the fertilizer has been applied before the rain, and it can no longer be applied; some farmers are afraid of applying peach fertilizer to cause cotton shade; some say cotton. At the end of the period, there is not much effect on the fertilizer, so as not to cause waste; others think that it is enough to apply the peach fertilizer to the urea, no matter how much cotton can be absorbed... To do this, we must improve the understanding and make full use of the peaches. The role of fertilizer in increasing cotton production.

It should be counted as several accounts, one is the effective season account. Generally, the effective bud period of cotton is around August 20, and the effective flowering period is around September 10. Now, the peach fertilizer is applied, and the effective growth period is still very long. The second is the peach fertilizer cost account. People are used to applying urea as cotton peach fertilizer. The current market price is 1.2 yuan to 1.3 yuan per kilogram of urea, and about 15 yuan per mu is about 40 yuan. The third is the investment income account. According to many years and more practice, the application of peach fertilizer is more than 15~25 kg per mu, and the average yield of seed cotton is 20 kg, and the price per kg of seed cotton is estimated to be 5 yuan, which can increase 200 yuan per mu. The ratio of input to income is 1:5, which is still very cost-effective.

It is clear that the law of cotton fertilizer needs to know the law of cotton fertilizer transportation, and it is very practical to guide the fertilization of field cotton. According to the research of the agricultural scientific research department, before the large amount of cotton is applied to the peach, the nutrients are mainly transported to the growth point of the cotton plant; after the cotton plant is planted in a large amount, the nutrient is mainly transported to the cotton peach on the fruit branch. Therefore, the application of the peach fertilizer does not have to worry about the madness. Shade.

According to the growth of cotton this year, according to the growth of cotton this year, the peach fertilizer is applied in a classified manner. If the peach is more, the peach fertilizer can be applied before August 10, and the peach blossoming progress is slow, and the peach fertilizer can be extended. time. The second is the amount of fertilizer applied, generally about 15 kg of urea per mu, and 10 kg of potassium fertilizer per mu of potassium-deficient cotton field. The third is the fertilization method. It is better to apply it before the rain. Do not apply urea before the rain to prevent burning cotton seedlings.
