Agricultural film covering method
In the current agricultural production process, the application of agricultural film can effectively reduce the occurrence of farmland diseases, but the application of agricultural film should pay attention to many principles, this issue of "Agricultural Resources Weekly" for everyone to introduce the basic methods of agricultural film cover I hope to help farmers' friends.
1. Pure dry fields: In addition to the rainy season, the long-term drought of cultivated land cover film not only does not achieve its intended effect, but also aggravates drought conditions.
2. Barren fields: Due to insufficient fertilizers in barren fields, the demand for crops can't be met, and the cover film also has no effect of increasing production and income.
3. Clay fields: clay on the ground, plastic film and the ground is not easy to be attached to the wind blow, damage the film material, lose its efficacy.
4. Multi-grass fields: Excessive amounts of weeds are cultivated. Although herbicides are sprayed before sowing, some weeds with underground rhizomes still puncture or lift the membranes.
5. Sandy land: The sand land covers the mulch and the ground temperature is too high at noon, especially in the case of drought, which is harmful to crops.
