Although cotton is a relatively tolerant crop, high yields and stable production require cotton fields to have high fertility. According to the measurement by the Cotton Institute of China Academy of Agricultural Sciences, most of the cotton fields in the country are currently in poor fertility, and the abundance of nutrients varied. It is very unbalanced, especially in the cotton fields of the Yellow River Basin, with low organic matter content, insufficient supply of nitrogen, and rapid availability of potassium. The content drops rapidly, and the trace elements zinc and boron are also in the absence of or lack of potential. These have become an important factor constraining the continuous and stable growth of cotton production.
Cotton is a deep-rooted crop with a long growing period and requires a large amount of fertilizer. Cotton yield is closely related to soil fertility. Organic matter is one of the major material bases of soil fertility. In a certain range, soils with high organic matter content have high soil fertility. Therefore, the main way to fertilize the cotton field is to apply organic fertilizer and apply the appropriate quantified fertilizer to the soil before applying the base fertilizer. The depth of the application is deeper. After plowing, the soil and fertilizer are combined, the fertilizer effect is relatively stable, and the nutrients are released and maintained for a long time, which is favorable for improving the soil and fertility. Moreover, the organic fertilizer has a complete nutrient content that is conducive to the growth and development of cotton, robust plants, and enhanced stress resistance.
Practice has proved that cotton fields can only be used for chemical fertilizers, and they can achieve high yields in seasons when the weather is good, but it is difficult to achieve sustained high yields. Because the use of chemical fertilizers for successive years will gradually deteriorate the soil properties, aggravate the consolidation, and worsen the permeability. This is one of the important reasons why the incidence of cotton disease has advanced year by year and the disease condition has been increasing year by year. It is also not realistic to rotate frequently in key cotton areas where the cotton fields are concentrated. Therefore, it is necessary to fundamentally solve the issue of continuous high yield of cotton, disease problems, and continuous cropping problems.
There are many types of organic fertilizers, including soil miscellaneous fertilizers, ring fertilizers, composts, green manures, cake manures, and human waste. Ring fertilizer is a high-quality organic fertilizer, and the main constituent is livestock and poultry waste. Direct return of straw to the field is also a good way to invest in organic fertilizer. There are 600-700 kilograms of an acre of cotton wood and 250 kilograms of roots, which are the main sources of organic matter in the cotton fields. Organic matter can improve the physical, chemical, and biological properties of soil, cementing the soil particles into a stable aggregate structure, while maintaining a certain degree of porosity between granules, improving soil water retention and fertility, and improving ventilation and tempering conditions, especially Improvements in sand and sticky grounds are more necessary. Organic fertilizer also facilitates the propagation of beneficial microorganisms in the soil, which can inhibit the activities of harmful microorganisms such as bacteria. To make land more fertile, transform low-yield farmland into high-yield farmland. Of course, this is not completed in one or two years. However, soil that has not been applied with organic fertilizer for many years can also be effective in the year of application, because organic fertilizers themselves contain certain nutrient components and can be used for direct absorption and utilization by cotton plants. The investment in cotton fields is actually an investment in land, and it is a basic long-term investment and construction.
The amount of fertilizers, straws, composts, and fertilizers can be determined according to the quality of the fertilizer. The use of 1-2 kilograms per acre is not much, and even higher yields are needed. If the quality of fertilizers is low and the quantity is small, then 50-75 kilograms of Mushi cake fertilizer should be used. In rural areas, there are many specialized households and å…¼è¥ households with livestock and poultry breeding. Organic fertilizers are also commercialized. Nearly pure livestock and poultry manure is sold. Mu can be applied to 300-500 kg. Fermentation is required before application. Otherwise, it will lead underground. Pests.
China's land resources are limited. To meet the growing demand for agricultural and livestock products, we must continuously improve land productivity. Therefore, the application of organic fertilizer not only has important practical significance, but also has far-reaching strategic significance.
At present, it is a good time for the autumn cultivation and basic fertilizer application in cotton fields. Late this year, the arable time will be extended. Those who complain about the poor soil quality and land resources of cotton fields are those who have low and unstable cotton production. Those who are troubled by cotton diseases should immediately take action to change the conditions of the land they are living on by applying organic fertilizers. , I am sure that the year and the future will be rewarded.
