Abstract
The invention provides a method for transforming salinization and low yield farmlands, relating to a method for transforming saline-alkali land. The invention solves the problems of short duration period, incapability of removing salt and alkali completely and recurrence of a chemical method, and large investment in a method of combining modern implantation and irritation technology in the existing method for transforming saline-alkali land. In the invention, the thickness of a sandy soil layer is calculated according to the pH value of the salinization and low yield farmland soil, sandy soil covers the surface of the salinization and low yield farmland in a soil freezing period, and plowing and ridging are carried out in spring to plant crops. The farmland transformed by the method in the invention has long duration period, can ensure the soil pH value to be within 6.5-7.5 in a long time without recurrence, and has low input; the cost can be recovered in two or three years after transformation; and the invention is applicable to transformation of saline-alkali land.
Description
Technical field
The present invention relates to the method on transformation salinity ground.
Background technology
The salinization of soil of China is on the rise, basicity is generally higher, serious salt affected soil regional plant almost can not be survived, the area that can till the land is reduced year by year, alkaline land improvement is the important channel that we increase arable area, the method on existing transformation salinity ground has following two kinds: one, chemical method: by chemical improvement agents such as calcareous materials such as gypsuming and ardealite, acidic materials and the water-loss reducer physicochemical property of improving the soil, this method lasting period is the longest to be 15 years, lasting period is short, can not thoroughly remove saline and alkalinely, the phenomenon of recurrence is arranged; Two, the method that combines of modern plantation and irrigation technique: measures such as rake loosens the soil by turning over, irrigation strengthen soil and drench salt, again by the plantation saline alkali tolerant plant, manually set up litter layer, applying organic manure, organic manure and turn over modes such as pressing green manure, increase the cover degree of soil, reduce soil evaporation, improve soil condition, but this method per hectare is made an investment in 2000 yuan/year～4000 yuan/year, investment is big.
Summary of the invention
The present invention is in order to solve the method chemical method lasting period weak point on existing transformation salinity ground, can not thoroughly remove saline and alkaline, the phenomenon that recurrence is arranged, the method that modern plantation and irrigation technique combine is invested big problem, and a kind of method of transforming salinization and low yield farmland is provided.
The method of transforming salinization and low yield farmland of the present invention, carry out according to the following steps: one, between April November to next year in every year, detecting salinization of soil low yield farmland pH in soil is x, then by formula d (centimetre)=20 (centimetres)-5 (10-x) (centimetre) calculate sandy soil layer thickness d, by the sandy soil layer thickness d that calculates sandy soil are covered the salinization of soil low yield farmland face of land again; Two, spring, crops were planted in the ridging of turning over according to a conventional method.
The soil that sandy soil described in the step 1 mix for the clay by 80%～98% sand and 2%～20%.
Crops described in the step 2 are corn, sunflower, jowar, leguminous forage or silage corn feed.
Salinization of soil low yield farmland standard of the present invention is salt ion content 〉=0.4%, pH value 〉=9, basicity 〉=50%, it wherein is principal character with the alkalization, the salt content that lacks enough capillary interstices and sandy soil according to sand ground soil is low, the pH value is low, the characteristics that basicity is low are in the annual frozen soil phase, promptly between April November to next year, sandy soil are transported to the salinization of soil low yield farmland, cover above the low yield farmland, form one deck sandy soil layer and cover the former salinization of soil low yield farmland face of land, reduce evaporation, stop salinity to move to land surface, simultaneously, utilize sandy soil to mix, reduce the upper soll layer salt content with the topsoil of salinization of soil low yield farmland, reduce the pH value, reduce basicity, improved farmland salt ion content is 0.15%～0.2%, and the pH value is 6.5～7.5, basicity is 12%～17%, becomes high-yielding grain fields or high yield feed field.
But method large tracts of land of the present invention is implemented, because saline-alkali soil clay content height, and can not cause the desertification problem after sandy soil mix, do not change once the soil property of transforming mixed soil, lasting period is long, can keep pH in soil for a long time in 6.5～7.5 scopes, does not recur; 3.5 yuan～4 yuan of every cubic metre of sandy soil prices, 1.4 ten thousand yuan/hectare～1.8 ten thousand yuan/hectare of the costs in transformation per hectare saline land, improved farmland is used for maize planting, sunflower, jowar, leguminous forage or silage corn feed, income is 5000 yuan of/year hectare～8000 yuan/year hectares, both transformed and be recoverable to cost in back 2 years to 3 years, economic benefit and ecological benefits that long-term later on acquisition continues.
