Embodiment 1

[0047] An improved soil for vermicompost saline-alkali land, which is prepared from the following raw materials in weight percentage: 20% of sawdust, 15% of phosphogypsum, 5% of fermented kitchen waste, 50% of vermicompost, and 10% of sodium ion adsorbent. Wherein, the preparation method of vermicompost is as follows:

[0048] Crush the straw into granules, then mix the granules with the sludge from food enterprises and stir evenly to obtain earthworm feed;

[0049] Feed earthworms with earthworm feed, until the sludge in the earthworm feed has no odor and peculiar smell, and becomes soft and dark brown;

[0050] The vermicompost is separated from the vermicompost, and then the vermicompost is air-dried so that the water content in the vermicompost is less than or equal to 30%, and the vermicompost is obtained.

[0051] The rest of the raw materials are existing mature raw materials, which are directly purchased; then the preparation method of the improved soil in this embodi...

Embodiment 2

[0054] An improved soil for vermicompost saline-alkali land, which is prepared from the following raw materials in weight percentage: 20% of husk chaff, 15% of phosphogypsum, 5% of fermented kitchen waste, 50% of vermicompost, and 10% of adsorbent; The preparation method of manure and the improved soil is the same as in Example 1.

Embodiment 3

[0056]An improved soil for vermicompost saline-alkali land, which is prepared from the following raw materials in weight percentage: 25% of sawdust, 10% of phosphogypsum, 3% of fermented kitchen waste, 47% of vermicompost, and 15% of sodium ion adsorbent; The preparation method of vermicompost and the improved soil is the same as in Example 1.

Abstract

The invention discloses wormcast saline alkali land improved soil and a method thereof for improving saline alkali soil. The improved soil is prepared from, by weight, 10-30% of wood bits or rice chaff, 5-25% of ardealite, 1-10% of food waste garbage yeast, 30-70% of wormcast and 1-20% of an adsorbent. The invention further provides a method for improving the saline alkali soil. The problem that the improvement effect of existing saline alkali land is poor is solved.

Description

technical field [0001] The present application relates to a soil improvement method, in particular to a soil improvement method for vermicompost saline-alkali land and the method for improving saline-alkali soil. Background technique [0002] Saline-alkaline soil is soil that is too salty or alkaline. The classification indicators of saline-alkali land are as follows: mildly salinized soil, the soil salt content is 0.1-0.2%; moderately salinized soil, the soil salt content is 0.2-0.4%; severe salinized soil, the soil salt content is 0.4-0.6%; ( In most of our country, the salt content is calculated with 30 cm soil plow layer.) Another indicator to measure the saline-alkali land is the pH value, generally 7.5 is neutral, <7.0 is slightly acidic, and >7.5 is slightly alkaline. [0003] The coexistence of salt and alkali determines the complexity of saline-alkali land improvement. The same plant, under the same salt content, shows differences in salt tolerance due to di...
