A method of using corn stalks to control desertification and afforestation

Abstract

The invention provides a sand-control afforestation method by use of corn straw, which mainly includes steps of the first step, excavating planting caves in the middle part of a windward slope of a sand dune in spring according to that the direction between lines is perpendicular to a main wind direction and direction between plants is in parallel to the main wind direction; the second step, planting a bundle of bundled corn straws at one side of the windward direction of the excavated planting cave; the third step, planting a cluster of 2-5 sacsaoul nursery stocks in the middle part of the planting cave; the fourth step, after planting the nursery stocks, filling wet sand in the planting cave, and then flattening the planting cave by wet sand, and compacting wet sand in the cave; the fifth step, adding water in the compacted planting cave; after water in the cave is completely penetrated, covering the rest excavated fine sand on the planting cave. The method is small in capital input,low in labor amount, and high in average storage rate, shrub coverage, nursery stock growth, and other technical indexes; the method is feasible; meanwhile, the corn straw is effectively used, the afforestation process is ecological and environment-friendly, and does not bring any environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of ecological sand control and relates to a method for sand control and afforestation by using corn stalks. Background technique [0002] The land desertification in Northwest my country is serious, the desert area is large, and the task of desertification prevention and control is heavy. At present, grass grid sand barriers are mostly used for sand control and afforestation in the desertified areas of Northwest China. Seedlings are planted in the grid to weaken the wind and protect the growth of seedlings. However, the use of grass grid sand barriers requires a lot of funds and labor input. According to the applicant's calculation, the average investment of grass grid afforestation needs to be about 800 yuan per mu, which is financial pressure for underdeveloped desertification areas. very big. Therefore, must seek a kind of sand control afforestation method with small investment and high survival rate. ...
