Problems solved by technology

[0004] Disadvantages of physical improvement: through measures such as leveling the land, removing soil, pressing sand, loosening the soil, and lifting the field, the capillary action of the soil is destroyed, and the further accumulation of salt to the surface is blocked
[0006] Disadvantages of chemical improvement: A large part of the appearance of saline-alkali soil is due to the extensive use of chemical fertilizers and pesticides, which leads to soil compaction, gradual deterioration, and eventually destruction

Embodiment 1

[0044] like Figure 2-4 Shown, the method for microbial ecological improvement of saline-alkali land of the present embodiment is carried out in No. 1 test field of saline-alkali land, and comprises the following steps:

[0045] 1. Apply microbial fermented fertilizer to the saline-alkali land to be improved, and evenly spread the crushed straw, and then spray the diluted MP compound probiotic preparation; the application amount of microbial fermented fertilizer is 40kg / mu; the diluted MP compound probiotic The preparation is diluted according to the mass ratio of 1:300-500; after two weeks, the following steps are followed.

[0046] 2. Plant grass and cover straw at intervals in the saline-alkali land to be improved according to the ratio of 1:2;

[0047] Planting grass involves the following steps:

[0048] a. Soak grass seeds (grass seeds are tall fescue, bluegrass, and ryegrass seeds mixed according to 3:3:4) with diluted MP compound probiotic preparation for 4 hours, th...

Embodiment 2

[0070] The difference between the method of microbial ecological improvement of saline-alkali land of the present embodiment and embodiment 1 is: the improvement method of the present embodiment is carried out in No. 2 test field of saline-alkali land; The application amount of the microbial fermented fertilizer of step 1 in the improvement method is 60kg / mu; The soaking time of the grass seeds in step a of planting grass is 12 hours; the watering time in step b is before 10 o'clock in the morning; the application amount of microbial fermented fertilizer on the saline-alkali land covered with straw is 60kg / mu;

[0071] The amount of each raw material in the microbial fermented fertilizer of the present embodiment is as shown in serial number 2,4 in table 1; The amount of each raw material in the MP composite probiotic preparation is as shown in serial number 2,4 in table 2; MP composite probiotic strain The ratio of each bacterial species is shown in No. 2 and No. 4 in Table 3;...

Abstract

The invention discloses a method for microbial and ecological improvement of saline-alkali land, relates to a land preparation method, in particular to a fertilizer application and planting combined land preparation method for improvement of the saline-alkali land and aims to provide a method which is simple to operate, low in cost and pollution-free and is used for microbial and ecological improvement of the saline-alkali land. The method for microbial and ecological improvement of the saline-alkali land comprises steps as follows: a microbial fermentation fertilizer is applied; straw is spread; an MP composite probiotic preparation is sprayed; glass planting and straw covering are performed alternately in the ratio of grass to straw being 1:2 in the first year; glass planting and straw covering are performed alternately in the ratio of grass to straw being 2:1 in the second year; grass is planted in the whole land in the third year. According to the method for microbial and ecological improvement of the saline-alkali land, the MP composite probiotic preparation and the microbial fermentation fertilizer are matched and applied to the saline-alkali land and are also matched with grass planting and straw covering, the unique physiological regulation function of microorganisms and long effectiveness of the organic fertilizer are integrated, crop growth can be stimulated, the quality of agricultural products is improved and soil-borne diseases are reduced. The method is used for the field of agriculture planting.

Description

technical field [0001] The invention relates to a soil preparation method, in particular to a soil preparation method combining fertilization and planting for saline-alkali land improvement. Background technique [0002] Excessive use of salt-containing fertilizers in the soil, for dry land due to irrigation and evaporation, salts in the soil accumulate to the soil surface, resulting in higher salt concentration in the rhizosphere, etc. At present, in many countries, salts accumulate due to irrigation, causing soil waste and farmland desertification to become more and more serious. Although the salts, positive ions, and negative ions that cause crop damage are different due to different regions, it is still possible to make the excess salt accumulation that causes crop damage play an appropriate role and avoid or reduce crop damage. . At present, the improvement methods of saline-alkali land mainly include the following two types: [0003] 1. Physical improvements: (1) Le...
