Good cotton field management is conducive to increasing production. What are the key points of cotton field management?

Cotton promotes growth and transformation, and buds appear early, which is the key period of big buds, so it will consume more nutrients. We should fertilize cotton in time to replenish the lost nutrients. How to plant and manage cotton to achieve high yield?

In fact, it is the key period to determine the high yield of cotton, to promote the growth, transformation, early bud, big bud and early flowering of cotton and to build a high-yield shelf, to demand light, temperature, water and fertilizer for cotton, and to cause and spread diseases and insect pests. Therefore, growers must pay attention to strengthening field management.

Now there are more and more people growing cotton in rural areas, and everyone wants to get higher income by growing cotton. It's mid-June, and cotton is also in a critical period of growth, which has basically sprouted, so it is necessary to strengthen the management of cotton at this time to make it grow healthily.

The active accumulated temperature is 80 ~ 105 degrees, and the effective accumulated temperature is 860~ 1060 degrees, lasting for 23~3 1 day. Pruning and germination. After cotton plants germinate, fruit branches and leaf branches can be easily distinguished. Leaf branches, which farmers usually call lazy branches, have few buds, but the stems are thick and the leaves are long, even competing with the main stems for height. Knocking off leaves and branches can strengthen ventilation and light transmission and promote the growth of fruit branches.

Every year in mid-April, when new tea is picked at home, grandparents are busy planting cotton. Grandpa said that although the surface of cotton looks unremarkable, there are many stresses on growing cotton. First of all, if the cotton in the field is sown too early, it may be because the temperature is low, the cotton does not germinate or the germination time is prolonged, so the emergence of cotton in the field will be seriously uneven. Secondly, if the cotton in the field is sown too late, the normal growth and development time of cotton may be seriously shortened, resulting in a significant decline in the quality and quality of cotton itself.
