At present, autumn harvest crops have entered a critical stage of production formation. All localities should strengthen the management of the field in the later period, and strive to increase the harvest of grain and cotton crops in autumn. Agricultural production advice:

1. The southern part of the Northeast, the southern part of North China, and the upper part of Huanghuai will be exposed to rainy weather. It is necessary to pay attention to preventing the crops from being greedy and late. The crops should be applied to the greedy crops in the later stage according to the growth of the crops. The crops are ripe and mature, to avoid the danger of early frost, and to ensure timely and timely sowing in the winter wheat area.

2, the northern autumn harvest crop area should strengthen field management, according to the growth of various crops, timely fertilizer, prevent premature aging of the crops, promote full grain filling, increase grain weight.

3, North China, Huanghuai cotton area should be timely topping pruning, suitable application of flower and bell fertilizer, and strive to multi-gate autumn peach, timely harvest mature cotton before the rain, improve production and quality. The cotton area of ​​the Yangtze River Basin can adopt measures such as sprinkler irrigation to reduce the air humidity in cotton fields, improve the microclimate of cotton fields, and mitigate the effects of high temperature.

4. The southern rice area should strengthen the management of rice fields, adopt measures such as water temperature regulation and foliar spray fertilizer to prevent high temperature hazards; and do a good job of water storage and conservation to prevent autumn drought. In particular, the southeastern part of the southwestern region and the southern part of the south of the Yangtze River should pay attention to the active development of water sources and scientific irrigation to alleviate the adverse effects of drought on crops.

5. All localities should strengthen the monitoring and prevention of pests and diseases, and at the same time pay attention to prevent the adverse effects of local heavy rainfall on agricultural production.
