Method for comprehensively using fruit, grass and livestock in Jinsha river dry heat river valley degraded mountainous region

Abstract

The invention provides a comprehensive method for utilizing fruit trees, pastures and livestock on the deteriorated mountain lands at the dry and hot valley of Jinsha River, pertaining to the field of forestry, pasture and livestock. The method includes 8 steps, i.e. species selection, seedling raising, preparation of interplanting land, interplanting, care and protection, collection of fruits and legumens, cradling column flowers to feed goats and as well as stable-breeding and semi-stable-breeding of goats. The species select tamarind, column flower / grass and goat; by seedling raising, rational thick-planting, bottom dressing, top dressing, dry-season irrigation, feeding goats with column flower and grass, stable-breeding and semi-stable-breeding of goats, the total nitrogen of 0-20cm soil stratum of the planting area with 2 years of interplanting is increased by 0.025 percent, the organic substance is increased by 0.29 percent, the beneficial self-cycle of water and nutrition is achieved, and the cost is reduced; after 2 years of interplanting, the column flower and grass are used to feed goats, the income of the first year increases by RMB 7050-11150 / hectare and the income of the second year increases by RMB 17850-26050 / hectare; in addition, the harmonious development of the forestry, pasture and livestock and the improvement of deteriorated mountain lands at the dry and hot valley of Jinsha River are ensured.

Description

technical field [0001] The invention relates to the technical field of comprehensive agricultural utilization. Specifically, it relates to a method for comprehensive utilization of fruits, grasses and livestock in degraded mountains of the dry-hot valley of the Jinsha River. Background technique [0002] In the prior art, there have been many "comprehensive utilization technologies of fruit, grass and livestock" or "comprehensive utilization technologies of forest, grass and storage", but the present invention is aimed at the arid and hot valley area of ​​Jinsha River, low vegetation coverage, serious soil erosion and barren soil. The special soil, climate and ecological conditions, as well as the low level of rural economy, the contradiction between returning farmland to forest and grassland and the development of animal husbandry, carried out research on species selection and corresponding technical measures, and proposed the combination of tamarind and stylophyll combined...
