At the beginning of May, the spring sowing of cotton in the country basically ended. The Yangtze River and the Yellow River were being transplanted. The cotton seedlings in the northwest were basically finished. However, the climate in May is variable, with low temperatures, high humidity, or drought occurring alternately, and pests and diseases have also entered the re-emergence period. The management of cotton production should focus on preserving the seedlings and breeding seedlings. Strengthen technical guidance, organize experts and technicians, enter villages and households, conduct roadside field trips and diagnose, and effectively help cotton farmers solve practical production problems. The main measures are: replanting seedlings and replanting seedlings, checking seedlings on the plots, and finding dead seedlings. They must make timely replanting and transplanting to make up enough seedlings. At the beginning of May, the cotton fields in northwest China suffered from low temperature and frost damage.
Timely release seedlings, put high temperature burning seedlings. According to the weather forecast, when the maximum temperature reaches 30°C or more, the mulching of the mulching film shall be promptly released to prevent the high temperature from “burning the seedlingsâ€.
Timely seedlings are seedlings to prevent seedlings and seedlings. The first time the seedlings are used to ensure that the leaves of the cotton plant take the leaves. When the leaves are 2 to 3, they can be seeded.
"Naked seedlings" for transplanting cotton, require appropriate depth of ditch, so that "planting cotton such as planting vegetables," pouring enough "safe water", a cotton pound of water, promote plastic film coverage, promote premature hair. After harvesting the rapeseed of the Yangtze River, grab the time for transplanting cotton after rape.
Drainage and irrigation. When the Yangtze River enters the Meiyu period, it is necessary to ensure that the canal is unblocked; the Yellow River wheat is at the peak of its water demand and it is necessary to replenish the irrigation water to prevent the wheat and cotton from competing for water and cause the weak seedlings to delay and die.
Weeding and weeding increase the temperature of the ground. The use of cultivators for inter-row, inter-strain and mechanical operation walkways will help improve ground temperature and control weeds.
Prevent pests and diseases. Diseases at seedling stage include blight, anthrax, and damping-off diseases. The use of Bordeaux-based liquid sprays has a good disease-preventing effect. The preparation method is: the ratio of copper sulfate to lime:water is 0.25:0.5:50. Other preventive agents include carbendazim and thiram.
Seedling pests include seedling mites, ground tigers, thrips, snails, etc., seedling mites and thrips are treated with monocrotophos; earthworms are prepared with bait and formulated with baits, and snails are used for caesars, worms, and limes. Prevention. (Farmers' Daily Author: Maoshu Chun)
