Problems solved by technology

At present, the domestic research on the comprehensive development and utilization system of saline-alkali land is relatively slow, and the main focus is on washing and diluting with fresh water, neutralizing with chemical reagents, and improving through fine working methods. These methods are costly, slow to take effect and easy to rebound
Insufficient understanding of the arable application of balanced salinized soil by restoring soil microbial diversity in saline-alkali land and exerting microbial metabolism

Embodiment

[0015] A microbial preparation for improving saline-alkaline land and its application method, the raw materials of the microbial preparation for improving saline-alkali land include the following ingredients: a composite bacterial liquid composed of 1 part of Bacillus licheniformis, 1 part of Candida utilis and 2 parts of plant lactic acid bacteria , sludge with a moisture content of about 80% in sewage treatment plants, and dried rice straw;

[0016] The application method of described microbial preparation comprises the following steps:

[0017] (1) Treatment of rice straw: crush the rice straw into 5--10cm strips; evenly spray the compound bacterial solution consisting of 1 part of Bacillus licheniformis, 1 part of Candida utilis and 2 parts of plant lactic acid bacteria on the ground On the straw strips, the bacteria-carrying straw strips were obtained and set aside;

[0018] (2) Mixing of domestic sludge and bacteria-carrying straw strips: according to the volume ratio o...

experiment example

[0022] Experimental object: two saline-alkali lands with an area of ​​10,000 square meters in Aksu, Xinjiang, where tomatoes are planted, are divided into conventional land and experimental land according to different improvement methods.

[0023] Experimental method: the general treatment method is used routinely, and the microbial preparation for improving saline-alkali land according to the present invention is used experimentally, and the survival rate of seedlings, the output when picking and the salinity of the soil when picking are recorded.

[0024] Experimental results:

[0025] 　 Free salt concentration during picking Soil PH value when picking Seedling survival rate Average investment cost per mu average yield per plant test group 0.34% 6.8 87% 320 yuan 6.4 kg regular group 0.66% 8.1 63% 570 yuan 4.8 kg

[0026] As can be seen from the experimental results, a kind of saline-alkali soil improvement microbial preparation o...

Abstract

The invention discloses a microbial preparation for saline-alkali soil improvement and an application method thereof. The microbial preparation for saline-alkali soil improvement is prepared from a composite microbial inoculant composed of Bacillus licheniformis, Candida utilis and Lactobacillus plantarum, sewage treatment plant sludge and straw stalk. The application method of the preparation is simple: the composite microbial inoculant, sludge and straw stalk are mixed and applied into the trench of the saline-alkali soil, so that the microbial preparation can perform metabolism and reproduction in the saline-alkali soil to balance the pH value of the soil and mineralize the salt content in the soil, thereby improving the tillability of the saline-alkali soil and greatly enhancing the crop yield and seedling survival percent.

Description

technical field [0001] The invention relates to a microbial preparation for improving saline-alkali land and an application method thereof, belonging to the field of ecological environment protection. Background technique [0002] China is a country with a shortage of arable land, and its per capita land area is far behind the international per capita land area. The development and utilization of saline-alkali land, which accounts for more than 10% of China's cultivated land, has a great effect on increasing my country's grain production. The causes of saline-alkali land in my country and the severity of saline-alkali land are relatively complicated. From the perspective of causes, the saline-alkali land in the eastern coastal area is mainly caused by seawater; The North China Plain is mostly secondary saline-alkali soil caused by improper regulation of water resources and excessive irrigation; in addition to natural factors, human over-cultivation and over-grazing have cause...
