Abstract
The invention discloses the modification methods of alkali-affected soil, comprising the following steps: (1) digs out the dell with a thickness of 0.3m on soil, and with a thickness of the carbonization cotton stalk of 0.1~0.2m on the middle berth of hole, and cotton stalk is smashed to pieces；(2) yellow mud with a thickness of 0.1m is spread on carbonization cotton stalk, and watering stirs into fluid in yellow mud, and the desulfurized gypsum of 2cm is uniformly sprinkled on the yellow mud of fluid；(3) compound fertilizer is uniformly sprinkled on desulfurized gypsum, the compound fertilizer includes that ammonium bicarbonate 5~7%, urea 2~4%, stalk 10~15%, phosphate fertilizer 1~2%, magnesium sulfate 2~4% and the clay surplus of component and weight ratio obtain after mixing；(4) sand is laid on soil conditioner extremely to flush with ground.The present invention can improve soil chemistry composition by a large amount of sodium ion in displacement soil, so that Zinc fractions aggregate structure, increases soil water permeability, aeration, create good environment for plant growth.
Description
Technical field
The present invention relates to soil improvement fields, more particularly to the modification method of alkali-affected soil.
Background technique
Due to needing the region afforested largely to belong to Arid Sandy Areas, the evaporation capacity height in the region, soil site condition
And structure is poor, reproducing area soil soluble salt is more and is in higher alkalinity, permeability and poor water retention property, the soil in the region
Earth belongs to reproducing area salinized soil, therefore hinders the normal growth of afforestation nursery stock.
According to investigation, Chinese wetland with saline-alkaline is up to 23.3 ten thousand square kilometres, and wherein quite a few is distributed in Western China
Backlands area, such as Xinjiang, the Inner Mongol, Gansu, Qinghai, Shaanxi province or autonomous region.Salinization of soil problem seriously limits locality
Agricultural development and building for ecological shelter forest change, be that one of must be solved the problems, such as first in Eco-environment Construction of Western Region.
Summary of the invention
The purpose of the present invention is to provide the modification methods of alkali-affected soil.
The purpose of the present invention is what is be achieved through the following technical solutions:
The modification method of alkali-affected soil, comprising the following steps:
(1) dell with a thickness of 0.3m is dug out on soil, and with a thickness of the carbonized cotton of 0.1~0.2m on the middle berth of hole
Bar, and cotton stalk is smashed to pieces；
(2) yellow mud with a thickness of 0.1m is spread on carbonization cotton stalk, and watering stirs into fluid in yellow mud, in fluid
The desulfurized gypsum of 2cm is uniformly sprinkled on yellow mud；
(3) uniformly sprinkle compound fertilizer on desulfurized gypsum, the compound fertilizer include component and weight ratio ammonium bicarbonate 5~
7%, urea 2~4%, stalk 10~15%, phosphate fertilizer 1~2%, magnesium sulfate 2~4% and clay surplus obtain after mixing；
(4) sand is laid on soil conditioner extremely to flush with ground.
The moisture of the desulfurized gypsum is 10~15%.
The present invention can improve soil chemistry composition, so that Zinc fractions are reunited by a large amount of sodium ion in displacement soil
Structure increases soil water permeability, aeration, creates good environment for plant growth, meanwhile, alkali-affected soil prepared by the present invention
Modifying agent also contains the ingredient for promoting plant growth, can improve growth vigor of the plant in alkali-affected soil；Simultaneously by compound
Fertilizer can reduce the pH value of salinized soil, alkalization of soils degree and the total salt amount of soil, and reduce the improvement of salinized soil
Cost effectively improves the improved effect of salinized soil, so as to improve the quality and fertility of soil.
