specific Embodiment approach 1

[0006] Specific embodiment one: the management method of moderate saline-alkali grassland in this embodiment is realized according to the following steps: (1) determine the degree of salinization of grassland: in May at the beginning of the year, the surface vegetation coverage rate is 30%~60%. Take soil from saline-alkali grassland for testing, the soil pH value is 8.5-9.5 is moderate saline-alkali grassland; (2) Select grass species: choose the seeds of saline-alkali-tolerant plants, the seeds of plants with local growth advantages, or high-quality Cultivation of pasture seeds; generally Elymus chinensis seeds, Leymus chinensis seeds or sweet-scented clover seeds, the purity of the seeds is 90% to 98%; (3) Soil preparation: shallow plowing and light raking of the soil, the shallow plowing depth is 8-10cm, (4) Application of ecological preparations: take weathered coal with humic acid content greater than 35%, crush it into particles with a particle size of 0.1-5 mm, mix it wi...

specific Embodiment approach 2

[0007] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the grass kind selected in step (two) is a kind of in Elymus chinensis seed or Leymus chinensis seed. Other steps are the same as those in Embodiment 1.

specific Embodiment approach 3

[0008] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the grass kind that step (2) selects for use is the mixed grass kind of Leymus chinensis seed and sweet-scented clover seed, and the mixing ratio is 2:1. Other steps are the same as those in Embodiment 1.

Abstract

The treating process of moderately salinized grassland includes determining the salinized degree of the grassland; selecting seeds of saline-alkali tolerant plant including excellent pasture; tilling the soil shallowly; applying ecological preparation; and seeding through drilling and pressing for 1-3 times. The present invention can restore the vegetation fast and has the advantages of low cost, high efficiency and high adaptability.

Description

technical field [0001] The invention relates to a treatment method for saline-alkali grassland. Background technique [0002] The control of saline-alkali land is a worldwide problem. The global saline-alkali land area is nearly 1 billion hectares, accounting for about 1 / 4 of the total terrestrial arable land, and spread across five continents. The area of ​​saline-alkali land in my country is about 40 million hectares, mainly distributed in the three north and coastal areas. In recent years, the degree of soil salinization in my country has been increasing, which has become an important factor restricting my country's economic development. There are many causes of grassland salinization, but the main cause is the irrational development and utilization of human beings, such as overgrazing, farmland cultivation, oil exploitation, etc., which degrade, salinize, and even desertify grasslands, resulting in the reduction of grassland biodiversity. Productivity decreases, funct...
