Embodiment 1

[0014] 1. Site selection and site preparation:

[0015] a. Site selection: Choose a mountainous area with an altitude of 1,700-2,200 meters, an annual precipitation of ±1,000 mm, a humid climate, no pollution to the atmosphere, irrigation water, and soil. Barren land with shrubs and weeds.

[0016] b Soil preparation: follow the principle of "early and meticulous", cut off the above-ground plants with a sickle every autumn and winter, and clean up weeds and plant residues. Raw land is excavated from top to bottom along the contour line to form an equidistant platform with an inner cut and outer cushion on the natural slope. The soil depth is required to be 15 cm, and the width of the horizontal platform is 0.5 or 0.7 or 1 meter, depending on the slope. The table top is 30 or 40 or 50 cm high, depending on the slope. During the digging process, shrubs, weeds, and stone debris were removed, soil was sterilized with Dixon and quicklime, and decomposed farmyard manure was applie...

Abstract

The invention relates to a mountainous area non-reclaimed slope water-collecting and fertilizer-maintaining forest medicine ecological combined method and belongs to the technical field of plant cultivation. The method is the improved method and is characterized in that equidistant horizontal tabletops which are internally tangent and externally cushioned are overturned and dug on a slope along a contour line from top to bottom, the width of the tabletops is 0.5-1 m, the height of the tabletops is 30-50 cm and the depth of soil is 15 cm; multiple layers of water-collecting and fertilizer-maintaining horizontal closure tabletops are formed along the slope; the table distance is kept to be 20-30 cm when the tabletops are overturned and dug, and gentle slope shrub and herbaceous plant belts between the tabletops are reserved; alnus nepalensis or cunninghamia lanceolata or fir with the height being 1.0-1.5 m is transplanted along the tabletops according to the spacing in the rows and the spacing between the rows, wherein the spacing is 2*2 mm. Gentiana rigescen or salviae miltiorrhizae is selected to be planted for 3 years, paris polyphylla or rhizoma polygonati is selected to be interplanted for 3-5 years, or rhizoma panacis majoris or pinellia ternate which is resistant to shade and damp is selected continuously to be interplanted for 3-5 years, and circulation plantation of varieties is performed according to the man-made forest plantation period or formed shading degree conditions. The mountainous area non-reclaimed slope water-collecting and fertilizer-maintaining forest medicine ecological combined method has the advantages of being easy to operate, low in cost, easy to popularize and friendly to the environment. A good foundation is laid for the development of medicine under a forest, and good economic benefits, ecological benefits and social benefits are achieved.

Description

Technical field: [0001] The invention relates to an ecological composite method of forest medicine for water collection and fertilizer conservation on barren slopes in mountainous areas, belonging to the technical field of plant cultivation. Background technique: [0002] With the implementation of the policy of returning farmland to forests in cold mountainous areas, the area of ​​forests in mountainous areas has increased, and there have been problems such as barren land resources under forests, single growth of trees, long cycle, extensive management, low economic benefits, and inability to exert ecological benefits. Deforestation and reclamation in some areas have caused water and soil erosion. At the same time, the technical requirements for interplanting and interplanting of understory crops are high. It is necessary to consider the results of afforestation and select suitable understory crops. Therefore, it is imminent to optimize the planting mode of barren slope cro...
