Embodiment 1

[0053] A method for maintaining vegetation on deserted land in a grassland area, which includes: conducting on-the-spot measurement and section background investigation on the deserted land to determine various parameters of the deserted land. Investigate the types of vegetation in undamaged areas in the same area to establish a native plant bank. On the basis of the urban and rural land planning of the local government, according to the natural conditions of the vegetation restoration area, combined with ecological and production needs, determine the purpose of vegetation restoration as tourism . Then carry out the construction of vegetation restoration, first level the land, plow to a depth of 18cm, rake after plowing, and rake to a depth of 7cm, and then apply basic fertilizer and organic fertilizer 25000kg / hm 2 , and build irrigation pipes and fences on the waste land, wherein the main pipe is connected to multiple branch pipes at the same time, wherein the main pipe and t...

Embodiment 2-4

[0055] The restoration method of the deserted land vegetation in the grassland area provided by Examples 2-4 is basically the same as that of Example 1, except that the selection of vegetation seeds is different.

[0056] In embodiment 2, the useful life of vegetation seed is 3 years, and vegetation seed comprises Elymus 20% and fescue 5% as gramineous forage seed, and as leguminous forage seed comprises astragalus oblique stem 30%, flat clover bean 20% and Astragalus oblique stem 15%.

[0057] In embodiment 3, the service life of vegetation seed is 5 years, and vegetation seed comprises Lyyis 40%, new wheatgrass 30%, sand brome 5% and durum bluegrass 1% as gramineous pasture seed, and as bean Branch forage seeds include 24% of Astragalus oblique stem.

[0058] In embodiment 4, the useful life of vegetation seed is 9 years, and vegetation seed comprises Leymus 88% as gramineous herbage seed, and as leguminous herbage seed comprises flat clover bean 5%, astragalus oblique stem...

Embodiment 5-7

[0060] The method for restoring the vegetation of the deserted land in the grassland area provided by Examples 5-7 is basically the same as that of Example 1, except that the fertilizer ratio of the topdressing is different.

[0061] In Example 5, 15000 kg of mixed fertilizer was applied per hectare, wherein the mass ratio of urea, diamine phosphate and potassium oxide was 2:1:1.

[0062] In Example 6, 17000kg of mixed fertilizer was applied per hectare, wherein the mass ratio of urea, diamine phosphate and potassium oxide was 4:3:1.

[0063] In Example 7, 20,000 kg of mixed fertilizer was applied per hectare, wherein the mass ratio of urea, diamine phosphate and potassium oxide was 2:2:1.

[0064] The maintenance method for the vegetation of the abandoned land in the grassland area provided in this example is to conduct background investigation on the abandoned land in advance, and investigate the vegetation type of the undamaged section to establish a native plant bank, and ...

Abstract

The invention relates to the field of grassland construction, and provides a steppe area derelict land vegetation maintenance method and a steppe area ecological restoration method. The maintenance method includes the steps: performing background survey on a derelict land; surveying the vegetation type of an unbroken section and building an indigenous plant bank; determining vegetation restorationapplications; turning over the land; applying basic fertilizers before tillage or in the tillage process; laying irrigation pipelines at the bottom of the derelict land; building fences on the periphery of the derelict land; selecting vegetation seeds from the indigenous plant bank and sowing the vegetation seeds on the derelict land; covering the seeds with soil and compacting the soil; loosening the soil of a hardened ground after sowing; applying mixed fertilizers to the derelict land after seedling emergence; irrigating the derelict land by the irrigation pipelines. According to the maintenance method, a damaged steppe ecosystem can be restored, and ecosystem functions are restored. The steppe area ecological restoration method includes the steppe area derelict land vegetation maintenance method.

Description

technical field [0001] The invention relates to the field of grassland construction, in particular to a method for maintaining vegetation on deserted land in grassland areas and a method for ecological restoration in grassland areas. Background technique [0002] Abandoned grassland land refers to the unusable land that has been damaged by the original vegetation in the grassland area through the development process such as digging and stacking, as well as the abandoned land due to road rerouting, building ruins, village relocation, and garbage occupation. This part of the land is abandoned , it is necessary to restore vegetation to repair the damaged grassland ecosystem and restore its ecosystem function. If the restored vegetation is not properly maintained after sowing, the restored vegetation will have difficulty growing and the survival rate will be low. Contents of the invention [0003] The purpose of the present invention is to provide a maintenance method for the...
