Dryland wheat mulching technology is mainly through the surface covering film, moisture conservation and water saving, improve the ground temperature, so that dryland wheat to obtain high yield, stable yield, divided into the film ridge cover furrow sowing inter-membrane cultivation and the whole film mulching hole sowing cultivation of two kinds.

Dryland wheat mulching and straw mulching

Film ridge and furrow cultivation technology is a field semi-closed water retention cultivation technology, technical points: 1. Wheat harvest immediately after the shallow plowing stubble, deep plowing before voltaic rain, fine plowing with harrowing before autumn. 2. adequate bottom fertilizer, concentrated bottom application. 3. half a month or so before sowing ridging cover film. Can use machine-guided or animal power to start, spread the film, sowing a complete operation of machinery, but also artificial animal power first to start the ridge cover film, and then two rows of animal power planter sowing, the distance between the ridge 50 - 60 cm, the bottom of the ridge 25 - 30 cm, the height of the ridge 10 cm, the top of the ridge Arc-shaped, covered with film on the ridge, planting furrow 30 cm between the two ridges sowing, row spacing 20 cm, planting two rows, the film on both sides of the pressure tightly without leaving a mouth, and in the ridge film every 3 - 4 meters to play a soil belt, in order to prevent gusty uncovering of the film. 4. Select tillering force is strong, high rate of spikes, spikes of large grains, heavy grain, good yielding mid-culm varieties, generally drought-resistant Stronger watered land in the water fertilizer varieties can be selected to do dryland mulch cultivation varieties. 5. Sowing period than the local open field cultivation delayed 5 - 7 days, the amount of sowing appropriately reduced. 6. After sowing to strengthen the overwintering period of the mulch protection, wind uncovering film, preventing livestock trampled on the film, loosening the soil after the rain to prevent sloughing.

Mulch full cover hole sowing cultivation technology of land preparation, fertilization, selection of varieties, sowing period, sowing volume and the same as the monopoly cover film inter-cultivation technology. The difference is that it does not have a ridge, laying the film, using perforated hole sowing, 45 - 600,000 holes per hectare, 4 - 6 grains per hole. The current production of hole seeding machine can cover the film, punching, sowing a complete. Film with a width of 140 cm, thickness of 0.007 mm polyethylene microfilm, each sowed 7 rows of wheat, row spacing 20 cm, hole spacing 10 cm, width between 20 - 30 cm, sowing depth 3 - 5 cm. After sowing every 2 - 3 meters of soil to play a belt, with sowing and playing. After sowing timely seedling seeding, seedling growth encounter hole misalignment should be timely seedling hollowing out, hollowing out the hole next to the soil pressure to maintain the seedling position.

Straw mulching technology is to return straw to the field to cover the ground surface, to play the role of moisture conservation and water conservation, fertilization of the ground. Mulching and straw mulching technology is applicable to dryland wheat fields in Shanxi, Shaanxi, Gansu and other provinces in the northern winter wheat area. The northern Hebei and northwestern Henan areas can also be used for reference.
