Soil And Water Conservation Of Superior Plant Introduction And Extension

The project is mainly from foreign, outside the region of successful introduction andbreeding by space, preferably, radiation grafting and breeding, and breeding method for loessplateau region growing perennial American sweet pea, the United States of America pasturegrass, yellow Lansha Terrier grass, the United States, the United States of America Khambluegrass black walnut, ash, bristles, cassia, Tianshui No.1, HbF-92-3and so onSeabuckthorn breeding and utilization technology research. Summed up a set of new varietiesof plant propagation techniques, identified and their suitable condition, range, at the sametime to the United States, the United States of America Perennial Pea pasture forage grasssuch as the sheep digestibility, hay of the main nutritional components in sheep rumendegradation rate and grazing as coarse feed preparation dietary nutrient digestion rate andamino acid content of forage in systematic research on Forage in sheep, the nutritional valueof quantitative description, put forward the rational and effective utilization of forage scheme.In the gully region of the Loess Plateau hilly and gully area of Loess Plateau in Xifeng, adistrict of Suide, two district, three sub region of Lishi Tianshui and alluvial plain area ofHuxian, Lantian Xi’an planting perennial American sweet pea, the United States of Americapasture grass, yellow Lansha Terrier grass, the United States Kham bluegrass180.3hm2,demonstration planting. Hair wax, cassia, seabuckthorn varieties such as28.96hm2. Excellentnew varieties of grass and tree roots, stems leafy, rapid growth, regeneration ability, forageyield, seed yield, fruit yield and nutrition value of indicators were higher than the local cultivation of legumes alfalfa, forage rye grass, trees and Hippophae rhamnoides varieties of walnut.In the Loess Plateau area planting and transplanting the several pasture and forest, can wellcover the bare ground, reduce rainfall erosion and surface runoff. Not only can solve theproblem of feed, fertilizer and fuel, but also can prevent and control soil and water loss. Tosolve the cultivated plant varieties of a single, feed shortage problems of far-reachingsignificance. At the same time can be shortened to watershed management cycle, to speed upthe pace of the Yellow River watershed, ecological construction of soil and waterconservation to provide technical support.
