Mode of arranging and building main, auxiliary and intercropping host forests for herba cistanches, namely shelter forests against wind and for fixing sand

Abstract

The invention relates to a mode of arranging and building main, auxiliary and intercropping host forests for herba cistanches, namely shelter forests against wind and for fixing sand, and belongs to the field of forestry and ecological environment. The forests consist of a main host forest, an auxiliary host forest and an intercropping host forest. The main hosts of haloxylon ammondendrons are arranged in diamonds, wherein an included angle of each two opposite angles of each diamond are 60 degrees; the distance between each two opposite angular vertexes is the tree shadow length of a 2-meter haloxylon ammondendron during sunrise and sunset on the summer solstice in the lunar calendar; one haloxylon ammondendron is planted at each opposite angular vertex; every three adjacent haloxylon ammondendrons form an equilateral triangle; and every four haloxylon ammondendrons form a diamond. The auxiliary hosts of caragana and Chinese wolfberry are respectively planted on two opposite sides of each diamond; and no trees are planted on the other opposite sides. A 0.5-meter periphery of each main host of haloxylon ammondendron is a blank area. Intercropping hosts of nanophyton erinaceum and artemisia stelleriana are intercropped at the blank area of each two adjacent diamonds. Herba cistanche is planted at the roots of haloxylon ammondendrons. The mode has the effects of blocking off and filtering sand wind, reducing a wind speed, retaining sand storm and preventing the generation of cyclones. The mode can be used for effectively controlling desertization expansion, improving the ecological environment and developing a herba cistanches industry.

Description

technical field [0001] The mode of collocation of the present invention to build the main, auxiliary and intercropping host forests and windproof and sand-fixing forests of Dayun belongs to the field of forestry and ecological environment, and particularly relates to a forest building method that combines hosts and windbreak and sand-fixing. Background technique [0002] Xinjiang is one of the areas with serious desertification problems in my country. Although people have made a lot of achievements in the long-term governance of the desert, due to natural and man-made reasons, the spread of desertification has accelerated in recent years, and the grasslands that have been desertified , The rapid expansion of arable land has seriously threatened the survival of farmers and herdsmen. It is an urgent problem to be solved to effectively control the desert while sustainably utilizing the sandy land, restoring the weak ecological environment, and creating economic, social and ecol...
