Problems solved by technology

Although the treatment is carried out, there is still a phenomenon of "partial treatment and overall expansion", which makes the load on the grassland more and more heavy, the productivity continues to decline, disasters such as drought, fire, sandstorm, insect pests and rodent damage occur frequently, and the function of water and soil conservation is weakened. , has become one of the main reasons for soil erosion and flooding. The protection and construction of grasslands are related to national ecological security.

Embodiment 1

[0065] 1. Enclose desertified land, adopt engineering fences or biological fences to strictly protect desertified land, clearly stipulate that grazing is not allowed in ecological grass construction areas, livestock and human destruction are prohibited, so that the ecological system can be recuperated , to accelerate the natural recovery of vegetation;

[0066] 2. For large areas of natural grassland, especially where the water and heat conditions are poor and there is no way to improve and establish artificial grassland, the method of enclosure protection is adopted, that is, the land for treatment is enclosed by engineering fences, and livestock are prohibited from entering Grazing and man-made destruction, make the grassland recuperate and promote the natural recovery of grassland vegetation;

[0067] 3. Irrigation

[0068] Irrigation can be done once a year from the germination of pasture grass to tillering and branching, and once during the period of pasture grass storin...

Embodiment 2

[0082] Step 1 is the same as step 1 of embodiment 1;

[0083] 2. For plots where the surface soil is compact and has poor permeability, and the microbial activity in the soil is weak, and the productivity of the grassland decreases, the soil loosening measures are used to loosen the soil of the grass layer to improve the soil ventilation of the degraded grassland and strengthen the soil microbial activity. Promote the decomposition of organic matter, especially suitable for grasslands dominated by rhizome-type or rhizome-bunch grasses;

[0084] There are three types of soil loosening measures:

[0085] The first is to scratch the turf, and the equipment used for the turf operation is to be scratched by tractor tractors (rotary plows, dovetail plows, horn plows, etc.); the working depth is generally 10-15 cm, and the row spacing is 30-60 cm; Early spring or late autumn; the ground has just thawed in early spring, and the soil moisture is more, so the cutting operation is easy ...

Embodiment 3

[0090] Step 1 is the same as step 1 of embodiment 1;

[0091] 2. Re-seeding is carried out on grasslands with a vegetation coverage of 20%-40%. This type of grassland has a bare land area ratio of more than 60%, but has natural recovery capabilities; the areas that need to be re-seeded are: the original vegetation is sparse or overgrazing degraded places where vegetation is destroyed by overcultivation and excessive digging, causing soil erosion or wind and sand hazards; places where shrubs, poisonous weeds and other non-ideal plants have been cleared; the original vegetation has a single feeding value or species, and it is necessary to increase legumes or other Places with good pastures; Abandoned cultivated land after reclamation;

[0092]Supplementary sowing places require soil texture that can ensure plant germination and growth, a certain soil layer, annual precipitation of not less than 150 mm, and certain protection and management conditions after sowing; the choice of ...

Abstract

A method for culturing ecological grassland to prevent desertization includes such steps as using fence to encircle a ground region for inhibiting pasture, loosening soil, sowing grass, planting Chinese tamarisk or puccinellia in saline-alkaline land, irrigation, applying fertilizer and planting shelter forest.

Description

technical field [0001] The invention belongs to the technical field of crops, and in particular relates to a method for controlling desertification land. Background technique [0002] my country is a large grassland country with 6 billion mu of various types of natural grasslands, accounting for 41.7% of the land area and 13% of the world's total grassland area. Grasslands are renewable natural resources with multiple functions. It plays an important role in maintaining the global ecological balance; because the grassland ecosystem has been affected by both natural and human interference factors for a long time, especially unreasonable human interference, 80% of my country's usable grasslands have appeared in varying degrees. Three modernizations" (degradation, desertification, salinization). Although the treatment is carried out, there is still a phenomenon of "partial treatment and overall expansion", which makes the load on the grassland more and more heavy, the productivi...
