Method for building drought barren mountain feed shrubbery

Abstract

The invention relates to a method for building a drought barren mountain feed shrubbery, which comprises the steps of selecting tree species, ploughing soil, arranging planting points, afforesting, fostering and managing a feed shrubbery, and the like. Local shrub species of seabuckthorn, dasiphora fruticosa, dasiphora davurica, gray cotoneaster, caragana tangutica, spiraea alpine, and the like are selected according to a theory of being suitable for the soil and trees; a growing season is advanced to improve the water content of the soil, i.e. the soil is ploughed in the rainy season, and the afforestation is carried out when the soil is thawed in the spring of the next year; a running water acquisition method is adopted during soil ploughing; the planting density with the strain line spacing of 1*1.5m, which is adopted during afforestation, plays a role of stress resistance effect of population; and finally the fostering seal, rotational grazing and stump removing rejuvenation are adopted after the feed shrubbery is afforested, thereby being beneficial to promoting the growth and development of the shrub and improving the biological output of a feed forest. The invention has the comprehensive effect of improving the survival rate of shrub afforestation by30-40 percent.

Description

technical field [0001] The invention relates to an afforestation method of native tree species, in particular to a method for arid and barren hill feed shrub forest construction. Background technique [0002] There are "Afforestation Technology of China's Main Tree Species" edited by the Chinese Journal of Trees Editorial Committee and published by the Agricultural Press, and "Overseas Forestry Overview" edited by the Institute of Science and Technology Information of the Chinese Academy of Agriculture and Forestry and published by the Science Press. Afforestation methods and afforestation measures of Pinus sylvestris on the dry and sunny slopes of sand dunes. In addition to introducing the technical measures of container seedlings and bare root seedlings afforestation, the method of embedding seedlings in soil, and the method of planting against the wall of small pits, it also introduces Other afforestation techniques and methods. In terms of fodder shrub forest constructi...
