The invention discloses a grape mixed plantation three-dimensional cultivation desertification control method which aims at solving the problem of grapery damage caused by a windstorm in a wind desert area. The grape mixed plantation three-dimensional cultivation desertification control method comprises the steps of flattening sandy badlands, and planting grapes, asparagus and andorra creeping juniper. The three-dimensional cultivation mode is adopted, so that quicksand movement is effectively controlled, the wind speed is decreased, damage caused by a windstorm and surface evaporation are reduced, expenses are saved, and the income is increased; the ground coverage is increased, water and fertilizer competition is reduced, the three-dimensional screen can be effectively formed, and the area of bare sand is decreased. The method efficiently utilizes sand resources, improves soil, improves the desertification prevention and control efficiency, organically combines sand stabilization, vegetation ...

The invention discloses a method of cold-resisting cultivation method of transplanting seedlings of needle-leaved trees in cold and arid regions, in order to solve an overwintering problem of the transplanting seedlings of needle-leaved trees in arid regions of northwest China. The cold resisting method comprises steps of nursery field selection, normal field management, two times of winter water irrigation and arranging chemical agent for cold resistance. In early and middle of August and early of November, the Handilong nutritional agents are used for spraying leaf surfaces. Before the soil is frozen, Bordeaux mixture containing copper sulfate and lime with proportion of 1:1.5-2 and starch emulsion are prepared to spray the transplanting seedlings of needle-leaved trees. According to the invention, resistance and adaptability of nursery stocks of transplanting seedlings of needle-leaved trees are remarkably improved; cold resistance of the seedlings is improved; survival rate of seedlings ...
