Problems solved by technology

The stems are upright, clustered or flat, quadrangular, glabrous or slightly pubescent, with lush branches and leaves. Alfalfa has wide adaptability, likes warm and semi-humid climate conditions, and is not strict on soil. Except for heavy soil, It can grow in extremely barren sandy soil and over-acid or over-alkaline soil. It is most suitable for growth in deep, loose and calcium-rich loam. In the pastoral areas of northern Tibet, the overall soil environment is very suitable for the growth of alfalfa. However, due to the long winter time and low ambient temperature in northern Tibet pastoral areas, alfalfa often cannot survive the winter smoothly and often dies in large areas in winter, which seriously restricts the application and promotion of alfalfa in northern Tibet pastoral areas.

Embodiment 1

[0024] A method for cultivating alfalfa safely through winter in a high-altitude area, specifically comprising the following steps:

[0025] 1). First, when the temperature drops to 5-10°C, a strip of ground with a width of 50-200cm is separated on the alfalfa planting ground at the seedling stage of 0-2 years;

[0026] 2). Then turn over the ridges with a height of 30-50cm on both sides of the strip ground;

[0027] 3). Then cover the film between two adjacent ridges, and use the surrounding soil blocks to suppress the edge of the film.

Embodiment 2

[0029] see figure 1 , the present embodiment includes a frame 1, the frame 1 as a whole is a rectangular structure formed by mutual welding of profiles, and the end of the frame 1 is welded with a connecting seat 2 that can be docked with a traction device;

[0030] The frame 1 is sequentially provided with a stacking mechanism and a film covering mechanism from one end close to the connecting seat 2;

[0031] The ridge mechanism includes first adjustment sleeves 3 that are welded and fixed on both sides of the frame 1, and each first adjustment sleeve 3 is provided with a first positioning rod 4 that can be slidably matched with its clearance. The end of the positioning rod 4 is welded with a first shaft sleeve 5, and the first shaft rod 6 that can be slidably matched with the gap is arranged in the first shaft sleeve 5, and a lower bottom surface of the first shaft rod 6 is installed. The first coulter 7, a connecting rod 8 is welded on one side of the bottom of the first s...

Embodiment 3

[0042] First, the connecting seat 2 is docked with the traction equipment. In the process of dragging the frame 1, the first coulter 7 plows out the soil, and the piled soil share 9 that is connected behind piles up the plowed soil into a pile. For the field ridge with a height of 30-50cm, since the second coulter 14 is set outwardly by staggering 20-50cm from the first coulter 7, the second coulter 14 begins to plow out a film groove on the outside of the field ridge. During the running of the frame 1, the suppressing connecting rod 21 presses the edge of the film into the film groove through the suppressing wheel 22, and finally pushes and fills the soil dug out by the second coulter 14 into the film groove by means of the soil covering share 20. The whole process is fully automated, and the film separated above the alfalfa can make it survive the winter in the pastoral areas of northern Tibet, which is beneficial for the alfalfa at the age of 0-2 whose root system is not yet d...

Abstract

The invention discloses a cultivation method and device for safe wintering of alfalfa in high-altitude areas. The cultivation method for safe wintering of the alfalfa in the high-altitude areas specifically comprises the following steps: (1) separating out stripe-shaped fields with widths of 50-200 cm on the ground in which 0 to 2-year-old alfalfa at a seedling stage is planted when the temperature drops to 5-10 DEG C; (2) making field ridges with heights of 30-50 cm on two side edges of the stripe-shaped fields by carrying out turning-piling; and (3) covering the fields between two adjacent field ridges with films, and pressing edges of the films by using surrounding soil blocks. The cultivation method for safe wintering of the alfalfa in the high-altitude areas is simple in structure, convenient to use, and capable of effectively solving the problem of difficult wintering of 0 to 2-year-old alfalfa at a growing stage; and moreover, the cultivation method is beneficial to root development of the alfalfa, so that the situation of slow growth of the alfalfa in winter in pastoral areas in northern Tibet can be thoroughly solved.

Description

technical field [0001] The invention relates to the technical field related to high-altitude livestock planting, and in particular to a cultivation method and device for safely overwintering alfalfa in high-altitude areas. Background technique [0002] Alfalfa is a perennial herb belonging to the leguminous family and alfalfa, with strong roots that penetrate deep into the soil and well-developed root necks. The stems are upright, clustered or flat, quadrangular, glabrous or slightly pubescent, with lush branches and leaves. Alfalfa has wide adaptability, likes warm and semi-humid climate conditions, and is not strict on soil. Except for heavy soil, It can grow in extremely barren sandy soil and over-acid or over-alkaline soil. It is most suitable for growth in deep, loose and calcium-rich loam. In the pastoral areas of northern Tibet, the overall soil environment is very suitable for the growth of alfalfa. However, due to the long winter time and low ambient temperature in...
