Mulching and straw mulching in Dryland Wheat
The mulching technology of dryland wheat mulching is mainly to cover the surface film through the surface, save water and save water, improve the ground temperature, so that the dry land wheat can obtain high yield and stable yield. It is divided into two kinds.
The interfilm cultivation technology of the film ridge cover groove sowing is a semi closed water conservation cultivation technique in the field. The main technical points are as follows: 1. after the harvest of wheat, the shallow ploughing and stubble were carried out immediately, the rain was plowed before the fall and the fine plow was raked before the autumn. 2. base fertilizer in base fertilizer concentration. 3. in the first half month cover film ridge sowing. The machine can be used with the ridging, the film spreading and the sowing of the animal power, and the artificial animal force can be covered with the ridge film first, and then the double row animal sowing machine is sown with the ridge distance of 50 - 60 cm, the ridge is 25 - 30 cm, the ridge height is 10 centimeters, the ridge top is arc type, the ridge is covered with a film of 30 centimeters between the two ridges, the row distance 20 centimeters, two lines, tight and tight sides of the film on both sides of the film. Mouth, and 3 to 4 meters on the ridge membrane to fight a soil belt, so as to prevent the wind from uncovering the film. 4. the varieties with strong tiller force, high spike rate, large spikelet, grain weight and high yield were selected, and the water and fertilizer varieties with strong drought resistance were selected as dryland mulching varieties. 5., sowing time is 5 to 7 days longer than the open field cultivation, and the sowing rate is reduced. 6., after seeding, we should strengthen the plastic film protection during overwintering, prevent wind and uncover the membrane, prevent people and animals from trunking, and prevent soil from hardening after rain.
The technology of film mulching, bunch planting, cultivation, fertilization, variety selection, sowing date and seeding rate is the same as that of ridge mulching. The difference is not tile ridge, plastic film, by drilling seeding and 45 per hectare, 600 thousand points, each point 4 - 6 tablets. Planter production at present selected film laminating, punching, sowing a complete. Film with a width of 140 cm wide and 0.007 mm thickness of polyethylene microfilm, 7 lines of wheat per sowing, 20 cm distance, 10 cm distance, 20 - 30 centimeters wide, and 3 - 5 cm depth. After planting, take a belt every 2 to 3 meters, and play with the sowing. After sowing timely check the seedlings to replant, seedling growth encountered dislocation of soil hole should be promptly cut out after seedling seedling, beside the hole pressure and soil conservation plants.
Straw mulching is the straw covered on the surface, the water moisture and fertility effect. Covering plastic film mulching and straw for northern winter wheat region in Shanxi, Shaanxi, Gansu and other dryland wheat fields. The northern part of Hebei and the northwest part of Henan can also be used for reference.
Ryoama Takama Plastics Co., Ltd. mainly include: 2m - 20m EVA multifunctional greenhouse film, metallocene long - life drop film, farmland film, degradation film, covering film, weed membrane, purple film, longevity film, preservative film, winding film, packaging film, geomembrane, water conveyance zone, etc. Sales covers Shandong, Jin, Hebei, Henan, Jiangsu, Anhui, Shaanxi, Gansu, Ningxia, Qinghai, Tibet, southern provinces and Xinjiang, Inner Mongolia and northeast provinces.
