Introduce several basic fertilizer methods for reference. In winter and spring, the cotton field was not even soiled, and the fertilizer could be evenly spread on the surface and then ploughed. Spring plowing depth of 18 to 20 cm, most of the fertilizer can be turned into the soil, and then carry out smashing. In this way, the fertilizer is applied deep, the storage time is long and the loss is small. In the case of 60-80 cubic meters of irrigation water, the fertilizer will not be lost as the water seeps into the groundwater. The vast majority of nutrients are still stored in 1 m deep soil layers for the absorption and utilization of cotton roots. The advantages of this method are the deep application of fertilizer, uniform application, solid soil, and sufficient storage. However, the amount of soil irrigation is relatively large, and the areas with poor water resources are inconvenient. Second, the scorpion to make squats, spreading fertilization after the spring plowing. This is suitable for areas where there is a shortage of water resources and watering is inconvenient. Pay attention to the fact that the cultivated land must be cultivated and reliable. Otherwise, the soil is loose and unfavorable to emergence. The disadvantage is that soil with poor soil quality is not conducive to conservation after ploughing; if fertigation is adopted after fertilization, try to Deepen to 13~15 cm, then make it practical. 3. Before sowing cotton, the 12 rows of wheat planter with a 15 cm spacing shall be used to evenly sow the fertilizer in the soil. Deepen as far as possible, and then ground smooth and flat, spread cotton every two or three days. The advantage is that all the fertilizer is applied to the soil and is relatively uniform; the disadvantage is that the depth of fertilization is limited. 4. Before sowing cotton, determine the size and position of the line spacing, draw a line with the plug, and broadcast the fertilizer in the middle of the expected small line. Finally, broadcast two lines of cotton on both sides of the fat line. The advantage is that the fertilizer is applied deeply and the line spacing is accurate; the disadvantage is that it requires two jobs. Fifth, sowing fertilization simultaneously. Install the fertilizer device on the seeder and stagger the seeding device before and after. Apply the fertilizer in the middle of two rows of cotton at the same time when sowing. The fertilizer is deep and the cotton seeds are sown. Since the seeds have not germinated yet, it can be regarded as the base fertilizer; this is the current comparison. Good base fertilizer method. 6. Fertilize deep in the big lines immediately after sowing. The same can be considered as base fertilizer. Because fertilizer input accounts for a large proportion of cotton field input, and the effect of fertilizer efficiency is also related to the surplus of cotton production, the emphasis on fertilization is a big issue related to the cost-effectiveness of cotton.
