How to cultivate and cultivate soil during the budding period
Cultivating and soil cultivation are the core of field management during the budding period and are important measures to achieve a stable and long budding period. Loose soil can aerate and increase temperature, accelerate nutrient decomposition, and improve soil fattening. Deep cultivating can cut off soil capillaries, reduce soil water evaporation, prevent drought and conserve moisture. It can also deepen the tillage layer, which is beneficial to root growth. Soil loosening and cultivating in cotton fields in saline-alkali land also have the effect of inhibiting the rise of salt.
During the budding period, plowing should be deep to promote root penetration and ensure stable growth of cotton trees.
In the bud stage when cotton has 5 to 6 fruit branches, the rows 17 cm away from the cotton plant can be cultivated to a depth of more than 10 cm, and 5 to 6 cm on both sides of the cotton plant. At the same time, cultivating should be flexibly controlled according to seedling conditions, climate, and soil quality. Generally, small seedlings should be shallow and large seedlings should be deep; weak seedlings should be shallow and strong seedlings should be deep; when the soil is hardened, has too much water, and has poor ventilation, it is necessary to cultivate and loosen the soil in time. To improve the quality, loosen the soil and hoe between rows and plants. Always keep the soil loose and the topsoil free of compaction and weeds. For cotton fields with a tendency to grow wildly, we can consciously reduce the number of loose soils and make the soil flat to inhibit the growth of the cotton root system; or we can increase the frequency and depth of cultivating and destroy part of the root system to control the wild growth.
Cotton needs to be cultivated during the bud stage. Soil cultivation has the following functions: first, it promotes new roots, increases absorption capacity, and enhances the ability to fix and support the above-ground parts, which is beneficial to resisting wind and falling; second, it increases the soil area, increases ground temperature, and promotes root growth; third, it facilitates rain Post-drainage can reduce field humidity and reduce boll rot; fourth, it reduces the growth of weeds and inhibits the occurrence of pests and diseases.
Cotton fields are covered with mulch film. Generally, the mulch film is removed when the flowers appear, and the soil is loosened, fattened, soiled, and watered in a timely manner.
