Agricultural advice:

1. Most winter wheat in the north will gradually enter the jointing and booting stage, and the water demand will increase. In this period, the lack of water and fertilizer will directly affect the number of spikelets and lead to reduced yield. All localities should check the grievances and seedlings in time, according to the situation of the decline of the sensation, timely and appropriate pouring of the jointing water, the wheat field with insufficient fertility should be applied to the grain and fertilizer to promote the formation of winter wheat.

2. The western region should clean up the sand and dust on the top of the greenhouse and the foliage of the plants in time to make the crops better for photosynthesis. In addition, we must pay attention to the weather changes, and combine sprinkler irrigation on conditional farmland to keep the soil moist and to remove dust from the surface of crops. At the same time, it is necessary to pay attention to shutting down the breeding grounds and preventing animals (pig, poultry, etc.) from being exposed to respiratory diseases caused by dusty weather.

3. The southern region seized the intermittent rainfall and seized the mature fruits and vegetables. In addition, the field ditches should be dredged in time to collect water from farmland and strive to reduce the impact of waterlogging. Timely implementation of field management measures such as seedlings, seedlings, and topdressing to promote the transformation of seedlings in affected crops. For the severely affected plots, we must do a good job of replanting and replanting to ensure that the time is not wrong. Organized personnel to carry out comprehensive inspection and reinforcement of greenhouse facilities, livestock and poultry farms, breeding ponds and agricultural electromechanical equipment. Increase the monitoring and prevention of pests and diseases such as pests and rice blasts, and minimize the loss of pests and diseases.
