How to increase cotton yield

Cotton is an indispensable item in our daily life. Clothes and quilts need cotton, which is the most basic warm-keeping measure in our life. At present, the domestic cotton planting area is very large, but the output of many friends is not very ideal. So how to increase the yield by planting cotton? Let's look at ways to increase the yield of easy-to-search cotton.

1, water and fertilizer management

In the process of planting, in addition to applying base fertilizer before planting, it is also necessary to apply topdressing in time according to soil fertility and plant growth. Topdressing is mainly composed of nitrogen, potassium and trace elements, and it must be applied more in cotton bud stage, flower and boll stage and other important growth stages. To control the amount of fertilization, it is not necessary to use excessive fertilization to prevent fertilizer damage from aggravating, but to reduce cotton yield. Then reasonable watering, keeping the soil moist, observing the weather changes, and stopping watering before it rains can effectively promote the firm root system of cotton, improve the drought and waterlogging resistance of cotton, and promote the stable growth and high yield of cotton.

2. Pinch your head in time

Picking is the fundamental measure to promote high yield of cotton. Pay attention to the time of pinching your head, not too early. If the head is pinched too early, the cotton plants will be distributed too closely. It affects cotton's absorption of light, resulting in too closed fields and reduced air permeability, which will not only reduce the yield, but also affect the quality of cotton. If you pinch your head too late, it may lead to cotton flourishing and dense branches, which will lead to unbalanced branches and buds, which will not only consume too much nutrients, but also reduce yield and quality. The coring time is mainly determined by factors such as weather and planting area.

3. Pinch method

There must be a correct way to pinch your head, not blindly. Although we only need to pinch off the top of cotton plants, there are still many aspects that need our attention in this process. Observe the growth of cotton, pinch the weak first, then pinch the good. Moreover, it is necessary to pinch all cotton plants at once, and try not to pinch them in batches to ensure that all cotton plants grow the same. Cutting the head can not only reduce nutrient consumption, but also effectively control pests and diseases, ensure the good growth of cotton and increase yield.

4, post-management

Always observe the growth of cotton after coring. It is best to spray a small amount of growth regulator to control the growth of cotton. But pay attention to the dosage, not too much, otherwise the growth of cotton will be extremely slow, or even stop growing. However, it depends on the growth of cotton and the size of the plant. If the plants are not big, there is no need to spray them. If the plants still grow vigorously after spraying, it is necessary to increase the amount of growth regulators. Prevent cotton from growing vigorously, reduce the flowering and fruiting rate of plants and improve cotton yield.

The above is a brief introduction to the methods of increasing cotton production. Cotton planting is relatively simple, but attention should be paid to management. Only by controlling planting density, preventing over-planting, controlling pests and diseases and strengthening field management can cotton yield be effectively improved. Let's call it a day.
