specific Embodiment approach 1

[0026] Specific embodiment 1: The method of combining straw biochar and microbial fertilizer to improve saline-alkali land in this embodiment is carried out according to the following steps:

[0027] 1. First, compost and ferment the organic fertilizer at 20-60 °C to obtain decomposed organic fertilizer, and then mix straw biochar, microbial fertilizer and decomposed organic fertilizer according to the weight ratio of 6-12:1:10-20 Evenly, stacking for 7 to 10 days, stacking height ≤ 1.0 meters, to obtain mixed fertilizer;

[0028] 2. Evenly spread the mixed fertilizer obtained in step 1 on the surface 0 to 2 days before soil preparation, and the application amount is 1350 to 2100 kg / mu;

[0029] 3. Immediately after spreading, cross rotary tillage for 1 to 2 times, the rotary tillage depth is 12 to 15cm, and it is suppressed immediately after rotary tillage, and then sowing can be done.

[0030] In this embodiment, within the range of 10-20 tons / ha of straw biochar application,...

specific Embodiment approach 2

[0031] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the straw biochar in step 1 is biochar formed by carbonization of crop straw, wherein the crop straw includes corn straw, rice straw, cotton straw and the like. Others are the same as the first embodiment.

specific Embodiment approach 3

[0032] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the organic fertilizer described in step 1 is forage animal dung, such as cow dung, sheep dung, and the like. Others are the same as in the first or second embodiment.

Abstract

A method assembling straw biochar with microbe bacteria fertilizer so as to improve saline land relates to the saline land improvement method, and aims to solve the technical problems that an existing saline land cannot plant crops or the crops output is low; the method comprises the following steps: composting and fermenting an organic fertilizer so as to obtain decomposed organic fertilizer, uniformly mixing the straw biochar, the microbe bacteria fertilizer and the decomposed organic fertilizer according to weight ratio: 1-12:1:10-20, and piling up the mixture for preparation; uniformly throwing the straw biochar, the microbe bacteria fertilizer and the decomposed organic fertilizer mixing improvement material on the soil surface 0-2 days before soil working, and appilication amount is 1350kg / mu; doing intersect rotary tillage for 1-2 times after fertilizer application, rotary tillage depth is 12-15cm, immediately suppressing the soil after rotary tillage, and then sowing is carried out. The method is simple, modifiers are straw biochar and manure, the materials are easy to get, so cost is low; the improved saline land is obvious in effect; the method is suitable for saline land improvement.

Description

technical field [0001] The present invention relates to a method for improving saline-alkali land. Background technique [0002] The function of biochar for soil improvement originated from the discovery and research of the black soil (TerraPreta) in the Amazon Basin of South America. As early as 1500 years ago, the South American Indians habitually used charcoal, manure and animal bones to improve the local soil, which is still very fertile. of South American Amazon Basin soils. Since the 1990s, there has been an increasing number of studies on the production of biochar from pyrolyzed biomass and its use as soil conditioner and carbon fixer. Foreign countries have carried out research work on the properties and characteristics of biochar and its effects on soil physical and chemical properties, microorganisms, and soil carbon sequestration, while China has just started, and basic research is relatively weak. The research on the structure and properties of biochar is very ...
