Embodiment 1

[0029] A method for improving slope soil in alpine mountains and inoculating AMF to promote vegetation restoration. After applying organic-inorganic compound fertilizer on the slope soil in barren alpine mountains, planting pioneer plant ryegrass and inoculating AMF includes the following steps:

[0030] S1, select fine breed:

[0031] Choose perennial ryegrass that has strong resistance to heavy metals and is suitable for the growth of plateau alpine climates;

[0032] S2, soil preparation:

[0033] On the slope of the alpine mountainous area with a slope of 34° to 40°, organic and inorganic compound fertilizers were applied according to the nutrient content required by ryegrass, and the fertilizer was ploughed and mixed evenly; the application rate was N 0.24g, P 2 O 5 0.12g, K 2 O 0.16g; wherein, the application amount of inorganic fertilizer in the organic-inorganic compound fertilizer is 9%, and the application amount of organic fertilizer is 91%.

[0041] Example 2 Effect test

[0042] 1. Test site settings:

[0043] The experimental site is located on the slope (27°59′32″N; 99°40′22″E) of the Pulang Copper Mine Area, Diqing Tibetan Autonomous Prefecture, northwest Yunnan, with an altitude of 3433m and a slope of 34°~40°. The mountain monsoon climate , the dry and wet seasons are obvious, the rainy season is from May to October, and the winter is cold.

[0044] The basic physical and chemical properties of the soil in the experimental site: pH 5.84, the contents of alkaline hydrolyzable nitrogen, available phosphorus, and available potassium are 87.5, 7, and 201 mg·kg, respectively. -1 , the total nitrogen, total phosphorus, total potassium, and organic matter contents are 2.5, 0.9, and 11.1 g kg, respectively -1 and 57.5g kg -1 ;

[0045] 2. Choose a good variety:

[0046] The perennial ryegrass with strong heavy metal tolerance and adapted to the plateau alpine climate, the ryegrass variety is Nicaragua;

Abstract

The invention discloses a method for improving side slope soil in a cold and cold mountainous area and inoculating AMF to promote vegetation recovery, which comprises the following steps of: applying an organic-inorganic compound fertilizer in the side slope soil in the cold and cold mountainous area with poor structure, physicochemical property and nutritional condition, planting ryegrass which can be eaten by livestock as a pioneer plant for the side slope vegetation recovery in the cold and cold mountainous area, and inoculating AMF, the method specifically comprises the following steps: selecting an improved variety; soil preparation; ryegrass is planted; harvesting ryegrass; applying an organic-inorganic compound fertilizer and inoculating AMF to evaluate the influence on the growth of the ryegrass. The method provided by the invention is ecological and environment-friendly, low in cost and small in engineering quantity, accelerates the restoration of the slope vegetation in the cold and cold mountainous area, and solves the problem of slow restoration of the slope vegetation in the cold and cold mountainous area.

Description

technical field [0001] The invention relates to the field of alpine mountain slope vegetation restoration, in particular to a method for improving alpine mountain slope soil and inoculating AMF to promote vegetation restoration. Background technique [0002] Alpine regions mainly refer to areas with high altitude and high latitude. Alpine mountainous areas are characterized by severe cold in winter, barren soil, low precipitation, large evaporation, low biological production, sparse vegetation, and fragile ecology. Because the development of resources and the construction of facilities will strongly disturb the original topography and ecosystem in the alpine mountain area, a large number of exposed slopes will be formed, which is not conducive to the sustainable development of regional ecological landscape and social economy. And there will be problems such as the reduction of soil and water conservation capacity, the reduction of biodiversity, and the reduction of the numbe...
