Embodiment 1

[0028] A biological improvement method for saline-alkali land, which is realized by combining a biological improver with ground cover. The specific preparation method of the biological improver is as follows:

[0029] (1) Make microbial inoculum: get the following raw materials by weight: 25 parts of soybean meal, 35 parts of rice bran, 10 parts of fish meal, 1 part of molasses (organic matter content ≥ 50%, water content 30%), EM bacterial classification (Runkang Source EM stock solution was purchased from Sino-Japanese joint venture Linyi Yikang Organic Agriculture Science and Technology Park Co., Ltd.) 1 part, 0.1 part of commercially available urea, 23 parts of water, then the above materials were fully stirred, put into a closed container, and carried out conventional Anaerobic fermentation process; the anaerobic fermentation process is carried out at a temperature of 25°C, the anaerobic fermentation process lasts for 20 days, the pH value is stable at about 3.5, and the a...

Embodiment 2

[0041] A biological improvement method for saline-alkali land, which is realized by combining a biological improver with ground cover. The specific preparation method of the biological improver is as follows:

[0042] (1) Make microbial inoculum: get the following raw materials by weight: 30 parts of soybean meal, 30 parts of rice bran, 8 parts of fish meal, 1 part of molasses (organic matter content ≥ 50%, water content 30%), EM bacterial classification (Runkang Source EM stock solution was purchased from Sino-Japanese joint venture Linyi Yikang Organic Agriculture Science and Technology Park Co., Ltd.) 2 parts, 0.1 part of commercially available urea, 35 parts of water, then the above materials were fully stirred, put into a closed container, and carried out conventional Anaerobic fermentation process; the anaerobic fermentation process is carried out at a temperature of 27°C, the anaerobic fermentation process lasts for 15 days, the pH value is stable at about 3.5, and the ana...

Embodiment 3

[0054] A biological improvement method for saline-alkali land, which is realized by combining a biological improver with ground cover. The specific preparation method of the biological improver is as follows:

[0055] (1) Make microbial inoculum: get the following raw materials by weight: 28 parts of soybean meal, 33 parts of rice bran, 9 parts of fish meal, 1.5 parts of molasses (organic matter content ≥ 50%, water content 30%), EM bacterial classification (Runkang Source EM stock solution was purchased from Sino-Japanese joint venture Linyi Yikang Organic Agriculture Science and Technology Park Co., Ltd.) 1 part, 0.1 part of commercially available urea, and 30 parts of water. Anaerobic fermentation process; the anaerobic fermentation process is carried out at a temperature of 26°C, the anaerobic fermentation process lasts for 17 days, the pH value is stable at about 3.5, and the anaerobic fermentation is completed;

[0056] (2) After mixing wheat and corn at a mass ratio of ...

Abstract

The invention belongs to the technical field of agriculture and particularly relates to a biological improvement method of saline-alkali land. The method is implemented by combining a biological improvement agent and ground mulching, and the microorganism improvement agent can neutralize soil salt and alkali, lower the soil salt content and further has the multiple functions of phosphorus-dissolving, potassium-dissolving, nitrogen fixation and the like, so that other microorganisms in soil are activated, soil nutrients and varieties of the microorganisms are increased, and effectiveness of unavailable nutrients in soil is promoted.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a saline-alkali land biological improvement method. Background technique [0002] The improvement of saline-alkali land is a difficult problem in the field of soil science at home and abroad. Although there are many traditional improvement measures, they are not thorough. At present, domestic improvement methods for saline-alkali land mainly include large-scale caustic soda, salt washing, and rice planting. Although water conservancy measures such as drainage to wash salt, well irrigation and well drainage to permeate the drainage belt have better results in thoroughly washing soil salt, but it requires good fresh water supply conditions, and the investment is large and the economic benefits are low. Contents of the invention [0003] The invention utilizes the combination of modern microbial technology, fermentation technology and traditional saline-alkali la...
