First, the soil is deep, with many granule structures, loose soil, good permeability, and strong water retention and fertilizer retention.
Generally, the clay is 30%-60%, the bulk density is 1.10-1.25g/cm3, the porosity is more than 55%, and the high-fertilizer loam is preferred.
Second, soil organic matter content should be 1% to 1.2%, 1.2% to 1.6%, and 1.91% to 2.2% in three types of soil, and its yield increase effect is 1s1.5s3.
Third, the soil moisture is more suitable The absorption of nitrate nitrogen by cotton depends on the suitability of soil moisture. Soil moisture not only affects nutrient uptake and biotransformation, but also affects a series of changes in chemical properties in the soil. The fertile soil preserves water storage capacity and enhances The water utilization rate can better meet the moisture requirement of cotton plants In view of the strong adaptability of cotton, it can also grow on some light-alkali lands, barren dry lands, and red soils in the southern hills. If gradual soil improvement is carried out, stronger cultivation management can also yield better yields.Plasma Products,Anti-Hbs,Safe Plasma,Safe Plasma Storage
