Problems solved by technology

However, due to climate restrictions, it is very difficult to plant alfalfa in alpine regions. The main reasons are that the low temperature climate makes forage growth and overwintering difficult, and the high water evaporation rate makes the alfalfa plantation land lack enough water to maintain alfalfa growth; Most of the natural grasslands are reclaimed into artificial forage fields, and the management is insufficient, resulting in grassland abandonment, degradation, and even soil erosion and ecological disasters

specific Embodiment approach 1

[0026] A method for planting alfalfa in alpine regions, including the following steps:

[0027] Step 1. Soil selection: deep soil layer, loose soil, soil pH value 7;

[0028] Step 2. Soil consolidation: Use agricultural machinery to deep loose the soil in the middle and late October in autumn. After deep loosening, apply the organic fermentation liquid residue to the soil to level the soil;

[0029] Step 3. Seed cultivation: select alfalfa varieties with fall dormancy level 1 and irradiate the selected seeds under strong light for 50 hours, then mix in rhizobia, and mix 1kg seeds and 10g rhizobia, Stir in and place in a cool and dry place, set aside;

[0030] Step 4. Sowing and planting: The soil is deep loosened again on the 15th day of April in spring, and the deep-turned soil is applied with basal fertilizer during the deep-turning process, and then artificially ditched and drilled, the seeding rate is 22kg / hm 2 , Sowing depth 1.5cm, row spacing 15cm;

[0031] Step 5. Field manageme...

[0049] A method for planting alfalfa in alpine regions, including the following steps:

[0050] Step 1. Soil selection: deep soil layer, loose soil, soil pH value of 8.5;

[0051] Step 2. Soil consolidation: Use agricultural machinery to deep loose the soil in the middle and late October in autumn. After deep loosening, apply the organic fermentation liquid residue to the soil to level the soil;

[0052] Step 3. Seed cultivation: select alfalfa varieties with fall dormancy levels 1 to 2, and irradiate the selected seeds under strong light for 50 hours, then mix in rhizobia, and mix in 1kg seeds and 12g rhizobia Stir in and place in a cool and dry place, set aside;

[0053] Step 4. Sowing and planting: The soil is deep loosened again on the 20th day of April in spring, and basal fertilizer is applied to the deep-turned soil during the deep-turning process, and then artificially ditched and drilled, the seeding rate is 23kg / hm 2 , Sowing depth 2cm, row spacing 10cm;

Abstract

The invention relates to an alfalfa planting method in high and cold areas and belongs to the field of planting. The method comprises the following steps: soil selection, soil preparation, seed cultivation, sowing and planting, field management, cradling time, water irrigation treatment and film laminating overwintering. By applying organic fermented liquid residues to soil during soil preparation, the usage of an inorganic chemical fertilizer is reduced; by uniformly spraying an alfalfa nutritional liquid every 35-50 days, water sufficiency when the alfalfa grows is guaranteed, and supplement of nutritional matters when the guarantee grows is also guaranteed. A trace element liquid in the alfalfa nutritional liquid contains trace elements such as copper, manganese, molybdenum, zinc and selenium, so that nutritional substances of alfalfa are supplemented. Because alfalfa as an important high quality feed has superstrong absorption capacity and enriching capacity on selenium and zinc and is an important carrier for converting inorganic selenium and zinc into organic selenium and zinc, an important source of extracting selenium and zinc from animals and people is realized. According to the method provided by the invention, the annual dry weight output of alfalfa in the high and cold areas is 1005.4kg/mu.

Description

Technical field [0001] The invention belongs to the field of planting, and specifically relates to a method for planting alfalfa in alpine regions. Background technique [0002] Alfalfa is a perennial herb of the legume Alfalfa genus. It is the world’s longest cultivation history and the widest distribution of fine pastures. It can effectively symbiotically co-exist with rhizobia for biological nitrogen fixation, thereby providing nitrogen to plants, which is indispensable in animal husbandry production. Lack of plant protein resources. As an excellent perennial legume forage, it has the advantages of high grass yield, high nutritional value, developed root system, cold and drought tolerance, and is known as the "king of forage." At the same time, it is also an excellent soil-improving and fertilizing plant. It has a wide range of adaptability in arid and semi-arid areas and is an important way to solve the lack of protein feed. However, due to climatic constraints, alfalfa pla...
