Xinjiang Cotton Growth Process Is Obviously Late &Nbsp; Strengthen Field Management To Promote Growth.
In 2010, the total sowing area of Wusu city was 1 million 200 thousand mu, of which sowing
cotton
599 thousand mu.
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 emergence of high temperature weather has promoted the growth of cotton, the growth process of cotton was significantly later than in previous years.
In view of the above situation, the Agricultural Bureau of Wusu city organized agricultural technicians to go to the countryside to enter the village to investigate the occurrence of crop soil moisture and diseases and insect pests.
According to the survey, most of cotton in Wusu entered the bud stage, and the demand for nutrients and water began to increase.
Cotton field
The critical period of management.
City agriculture bureau put forward: strengthening field management to promote healthy growth of cotton.
1, reasonable fertilization.
Because of the little demand for nutrients at seedling stage, generally, light fertilizer or no fertilizer is applied. After entering the bud stage, the amount of fertilizer needed is increased.
Strong seedlings should be applied less, weak seedlings should be applied more, sand land should be protected by water and fertilizer should be applied more, and sticky land should be applied less.
According to the technical requirements of soil testing and formulated fertilization, 10-13 kg of urea is applied to each acre to meet the needs of cotton plants.
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.
Because of soil fertility and
Varieties
The principles of light, diligent and early should be adopted for different flexibility.
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.
