Embodiment 1

[0040] The dried rape stalks are cut into 2~5cm stems. On the 1st to 12th day after the spring wheat is sowed, 500-700g / m will be sprayed evenly at one time 2 Of dried rape pods, dried rape straw or a mixture of both. When spreading, use a small amount of gradual spreading method. It is not advisable to spread too much cover in a concentrated manner. The purpose is to ensure that the cover can basically fall on the surface of the wheat field, so as to avoid overwhelming the wheat seedlings, that is, so as not to affect the germination and growth of the wheat seedlings; after spraying Normal management.

Embodiment 2

[0041] Example 2. The dried rape stalks were cut into 2 to 5 cm long stems. On the 1-12 days after winter wheat sowing, evenly spread 500-700g / m at a time 2 Of dried rape pods, dried rape straw or a mixture of both. When spreading, use a small amount of gradual spreading method. It is not advisable to spread too much cover in a concentrated manner.
