specific Embodiment approach 1

[0006] Specific embodiment one: the governance method of the mild salinization grassland of this embodiment is to carry out according to the following steps: one, the determination of the saline alkalization grassland degree: in May of the beginning of the year, the saline-alkali soil in the surface vegetation coverage rate is not less than 60% Take soil from chemical grassland for testing, if the soil pH value is not greater than 8.5, it is mildly saline-alkali grassland; 2. Grass seed preparation: choose the seeds of saline-alkali-tolerant plants or the seeds of dominant plants that grow well in the local area, or the seeds of excellent cultivated pastures , generally the seeds of Leymus chinensis, sweet clover or alfalfa; the purity of the seeds is 90-95%, the germination rate of Leymus chinensis seeds is not less than 20%, and the germination rate of sweet clover or alfalfa seeds is more than 85%; three. , site preparation: shallow plowing and light raking of the soil, the ...

Abstract

The treating process of lightly salinized grassland includes tilling the soil in the depth of 8-10 cm, crushing weathered coal with humic acid content greater than 35 % and preparing ecological preparation of granularity of 0.1-5 mm, applying the ecological preparation in 30-50 kg/mou, seeding grass in the seed amount of 1.5-3 kg/mou and soil covering depth of 2-5 cm and pressing for 1-3 times. The present invention can improve salinized grassland completely 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 improvement of saline-alkali land is a worldwide problem. The saline-alkali land area in the world is nearly one billion hectares, accounting for about a quarter of the total land area of ​​cultivated 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 Norths" and coastal areas. Especially in recent years, soil salinization has intensified and expanded, and it has become an important factor restricting the economic development of my country and some other countries in the world. factor. There are many causes of grassland salinization, but the main cause is the irrational development and utilization of human beings, such as overgrazing, farmland reclamation, oil exploitation, etc., which degrades the grassland, salinizes it, and even desertifies it. ...
