Full-film-covered soil sowing technology

The whole film-covered soil sowing technology is a full-surface-soiled mulching film + film-covered soil + hole sowing + no-tillage multi-till planting. The conventional open-field sowing wheat is replaced by a full-surface mulch film covered with soil, and the traditional mulching film sowed in wheat is planted once for one year. (茬) For continuous planting of a film-covered soil for 3 to 4 years (茬), change the large amount of conventional wheat sowing to precision sowing, change the human and livestock sowing to seed sowing machines, and integrate membrane surface sowing points to collect rain and cover The integration of steaming, rainwater enrichment and multi-planting technologies not only minimizes the evaporation of soil moisture, but also uses seeding holes to collect currents, enabling the efficient use of effective water resources, resulting in an average yield of 300 hectares of dryland wheat. More than kilograms, more than 100 hectares of open-broadcasting average yield per mu, to achieve stable yield and high yield of dryland wheat.

The main technology: After the site preparation, cover the ground with the mulching film, cover evenly a layer of fine cotton soil of about 1 cm on the mulch, then use sow sowing machine to sow wheat and other crops, sowing 8 to 12 pods per hole, spacing 15 cm to 16 cm. , The hole distance is 12 centimeters, the sowing rate is about 10 kilograms, and the number of acres is 35,000 points to 3.7 million points. It is suitable for semi-arid and semi-arid areas with an annual precipitation of 300-600 mm. It is suitable for dense crops such as wheat, flax, millet, buckwheat, soybean, rapeseed and barley.
