The Growth Process Of Wusu Cotton In Xinjiang Is Obviously Late &Nbsp; Strengthening Field Management To Promote Healthy Growth Of Cotton.

In 2010, the total sowing area of Wusu city was 1 million 200 thousand mu, of which 599 thousand Mu was sowed.

This year, owing to the generally low temperature in the Wusu city since spring, sowing time is relatively late, planting time is relatively concentrated, and the growth period of crops is generally pushed back for 20-25 days.

Although the recent high temperature weather has accelerated.

1, reasonable fertilization.

Seedling stage

2, reasonable irrigation.

Cotton irrigation should be determined according to soil moisture, and the mastery principle is "head water late, two water catch up".

At present, the soil moisture content of cotton in our city is relatively good, and the irrigation water is too early.

Early watering can lead to prolonged growth of cotton.

3, chemical control combined with fertilizer control.

The principle of light, diligent and early is to be grasps due to the difference of soil fertility and varieties.

In the early bud stage, the use of 1 2G to reduce the amount of amino acid per acre has a good effect on stabilizing the bud stage and setting up a high yield shelf.

It is necessary to overcome the bad tendency of seedling control.

4, strengthen pest control.

According to the survey, cotton bollworm and Aphis gossypii occurred in cotton fields, and no cotton bollworm was found.

In order to prevent gossypii gossypii, spraying insecticides such as avermectin and abamectin can be used to control cotton aphids.
