First, the choice of fields
The post-paddy green manure should be planted with a slightly higher topography, which is convenient for irrigation and platooning and for the middle and upper fertility plots with large sediment content.
Second, open the channel to prevent stains and drought
The cultivation of post-planted green manure is based on the use of no-tillage when the rice is not harvested. Therefore, it is necessary to ensure that there is no stagnant water in the field when sowing, so that the seedlings can be maintained without being rotten; in addition, the cultivation of post-planted green manure is affected by the winter drought. The impact should be on the Tianzhonggou, Tianbiangou and Xianggou, and some fields should also be open to the Tianwaigou so that the fields can be connected with the fields and the ditch can communicate with the ditch to ensure that the drought can be filled with water, and the water can not be stained after irrigation. Drainage, dry after the rain.
Third, timely sowing
The sowing of green manure after rice should be planted 10 days before the rice is harvested. The green manure will grow under the shade of the rice paddy and grow several leaves to improve the drought resistance after rice cutting.
Fourth, the amount of seeding should be sufficient
Green manure is the key to high-yielding basic seedlings. In addition, the cultivation of post-planted green manure is based on no-tillage, and the emergence rate is lower than that of general plots. Therefore, the seeding rate must be sufficient, and the seeding rate per mu must be maintained at 7-8 kg.
V. Rational fertilization and timely irrigation
After the rice is harvested, mu is applied to a farmyard fertilizer of 2000kg for frost protection and frost resistance. When the temperature rises in the coming year, water is sprayed 2-3 times in a timely manner to prevent seedlings from drying out. This is accompanied by the first irrigation and application of 40kg of compound fertilizer to the mu.
Sixth, timely pressure
When the green manure grows to 70cm in time to plow the paddies, too late seedlings are too long, the base is easy to lignify, reduce fertilizer efficiency, affecting cultivation.
