The whole film-covered soil sowing technology is a full-surface-soiled mulching film + film-covered soil + hole sowing + no-tillage multi-tillage planting. The conventional open-field sowing wheat is replaced by a full-surface mulch film covering the soil, and the traditional mulching hole sowing wheat is once covered with film 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 efficient use of effective water resources, and the average yield of dryland wheat reaching 300 More than kilograms, more than 100 hectares of open-broadcasting average yield per mu, achieving stable production 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 the hole sowing machine to sow wheat and other crops, sowing 8 to 12 grains 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.
