Winter wheat sowing is generally guaranteed, partial or continuous drought in autumn and winter

At present, the sowing of winter wheat across the country is about to be carried out on a large scale. In order to effectively improve the sowing quality of winter wheat, cultivate strong seedlings before winter, and consolidate the foundation for a bumper harvest of summer grain next year, the Ministry of Agriculture recently issued the "Technical guidance on Wheat planting in Autumn and Winter 2016".

On the whole, since July this year, there has been more rainfall in the main wheat producing areas across the country, the soil moisture is generally sufficient, the growth and development of crops in the previous crop is normal, and sowing at the right time in most areas is guaranteed. However, there is less rainfall and insufficient soil moisture in some parts of the northwest. At the same time, the meteorological department predicts that under the influence of El Nino, the precipitation in autumn and winter in the northern winter wheat region is less than that in normal years, and the temperature is generally on the high side, and continuous drought may occur in some areas, which is disadvantageous to the sowing and emergence of winter wheat and safe overwintering.

Specific to various regions, Huang-Huai and northern winter wheat regions are the largest winter wheat producing areas in China. The main factors affecting wheat production are shortage of water resources, frequent occurrence of natural disasters such as drought, freezing injury, dry and hot wind, and serious damage to stripe rust, sheath blight, powdery mildew and scab. The main factors affecting wheat production in the middle and lower reaches of the Yangtze River are waterlogging and high temperature ripening, which occur from time to time, and scab, powdery mildew, sheath blight and stripe rust are more serious. The main factors affecting wheat production in southwest winter wheat region are lack of sunshine, heavy rain and fog, few sunny days, and unfavorable factors such as early wet damage, winter and spring drought, late high temperature, rotten field rain and so on. Stripe rust is one of the main summer and overwintering areas of wheat in China. Stripe rust is serious. The main factors affecting wheat production in northwest winter wheat region are barren soil, drought and little rain. at the same time, Gansu and some parts of Xinjiang are the main summer and winter areas of wheat stripe rust in China, which have a great impact on the safety of wheat production.
