Agricultural production advice:

1. Wheat in winter wheat areas such as North China and Huanghuai enters the jointing and booting stage, which is also a critical period for water demand. All localities should timely water the joint water according to the soil moisture and rational fertilization to promote the formation of yield.

2. There is strong rainfall in the southern region. After the rain, it is necessary to clear the ditch in time to prevent the flooding and pests and diseases in the field. The rice area should strengthen the management of water and fertilizer in Putian and strive to cultivate strong growth.

3, the northeast spring sowing area to seize the fine weather, according to soil sputum, timely planting.
