Problems solved by technology

Among many saline-alkali soil improvement measures, water conservancy engineering measures, agricultural cultivation measures, chemical amendments and other methods have been widely used, but the effect is not ideal
Although chemical improvement measures can quickly change the soil structure, it may also cause secondary pollution; agricultural measures need to consume a lot of manpower, material resources and financial resources

Embodiment 1

[0026] A method for improving saline-alkali soil by using red clover and Elaeagnus angustifolia includes the following steps:

[0027] (1) Deep plowing of saline-alkali soil and applying decomposed organic fertilizer as base fertilizer. The decomposed organic fertilizer includes the following components in parts by weight: 20 parts of cow dung, 25 parts of straw, 20 parts of sludge, 1 part of bean dregs, 5 parts of vinasse, 1 part of tea seed cake, 2 parts of Bacillus subtilis, 5 parts of Bacillus licheniformis;

[0028] (2) Sowing red clover seeds, the sowing method is sowing, the sowing amount is 850g / mu, the sowing depth is 1cm, and the rhizobia and arbuscular mycorrhizal fungi are inoculated. The rhizobia inoculation method is to dilute the rhizobia and mix The method for inoculating the arbuscular mycorrhizal fungus is to evenly sprinkle the arbuscular mycorrhizal fungus inoculant on the ground and cover it with soil, and the arbuscular mycorrhizal fungus is Glomus terrestrial...

Abstract

The invention relates to the technical field of soil improvement, in particular to a method for improving saline and alkaline land through red clover and elaeagnus angustifolia. The method comprises the following steps of 1, conducting deep tillage and loose ploughing on the saline and alkaline land, and applying decomposed organic fertilizer to serve as base fertilizer; 2, sowing red clover seeds, and inoculating nodule bacteria and arbuscular mycorrhizal fungi; 3, removing overground parts and main roots of the red clover after the red clover is harvested, conducting ditching on the surfaceof soil, and sowing elaeagnus angustifolia seeds. By means of the improvement method, the salt content and pH of the saline and alkaline land are significantly lowered, the contents of soil nutrient substances such as the organic matter, nitrogen, phosphorus and potassium are increased, the growth of the red clover and the elaeagnus angustifolia is better, the economic value of the saline and alkaline land is increased while the saline and alkaline land is improved, and the method has certain practical significance in production.

Description

Technical field [0001] The present invention relates to the technical field of soil improvement, in particular to a method for improving saline-alkali soil by using red clover and Elaeagnus. Background technique [0002] Saline-alkali land is a general term for all kinds of saline soil, alkaline soil, and salinized and alkalized soil. According to the amount of saline-alkali content in the soil, it can generally be divided into three types of mild, moderate and severe saline-alkali land. As an important land resource, soil Salinization has seriously affected the regional ecological environment and food production. According to incomplete statistics from UNESCO and FAO, the global saline-alkali land area reaches 955 million ha 2 , And the total area of ​​saline-alkali land in my country is about 99.14 million hm 2 , Ranking third in the world. Saline-alkaline soil is mainly characterized by stickiness when wet and poor air permeability; when dry, it is hard and has poor water per...
