Four measures are adopted in time to remedy the cotton growth and restore the normal growth of cotton so as to reduce the loss of waterlogging.


Zhou Mingyan, a senior agronomist at the Hubei Provincial Department of agriculture, said that the harm caused by continuous heavy rainfall to cotton fields is that local cotton is sitting in "water jail". The growth and diapause of cotton plants or the large number of bolls and bolls are falling off, which will add to the damage of the late cotton.

But now there are 40 days from the effective bud stage of cotton, and the effective flowering period is about 70 days. There is remedial time and space.

In order to reduce the losses caused by waterlogging, we should focus on the following four measures.


First, in terms of emergency response,

We should highlight the "four robbery" and quickly restore the normal growth of cotton.

One is to drain the clear water and reduce the dark water, so that the cotton seedlings can get out of the water early and remove stains early. Two, it is necessary to rush the seedlings to wash the leaves and clear the dirt; three, to loosen the soil and break the board; when the field is dry, the soil should be broken up in time, the soil should be broken up, the ridging will be lifted, the air will be ventilated, the root system will be promoted, and the four is to catch the top dressing.

Combine the middle tillage and loosen soil, apply the right amount of urea, and spray the fertilizer outside the root.

The cotton fields with good cotton foundation, early fertilization and strong cotton growth should be adjusted in time to prevent the growth of cotton plants.


Second, later stage

It is necessary to strengthen autumn management and reduce peach yield.

We should vigorously publicize the experience of winning cotton harvest in autumn and in autumn.

One is to add flower and boll fertilizer, and then to apply peach fertilizer again.

Sufficient fertilizer is used to make up for the loss of nutrients in early stage and ensure the nutrient needs of late autumn peach.

Special attention should be paid to the application of potash fertilizer, and potassium fertilizer should be applied to the cotton fields with insufficient potassium application in the early stage to prevent the cotton plants from withering and premature aging.

Two is to strengthen pest control, to ensure that limited bolls and rare autumn peach are no longer harming by cotton pests.


At the same time, cotton farmers need to break the rules and make four "postponement" after the disaster.

One is to postpone the application of peach fertilizer to -25 days in August 15th.

The two is to postpone the topping time to -15 days in August 10th, making full use of the longitudinal growth advantages of cotton and increasing branches.

Three is to postpone spraying insecticide to terminate time and strengthen the prevention and control of cotton diseases and pests in later stage.

Four, we should postpone the time of pulling the stems, implement the small tilled seeds, and plant the wheat and rape in the cotton plantation.


In addition, Zhou Mingyan suggested cotton farmers set late autumn crops to increase the income of cotton fields.

Cotton fields with green shoots and vegetables can be set up to increase the income of cotton fields.
