Abstract

The invention relates to a method for improving farmland soil and belongs to the technical field of technical innovation of farmland soil improvement. The method for improving the farmland soil aims to achieving the technical goal that a chemical technology is replaced by a biological technology. The application of the biological technology is the technical key point to achieve the goal. The method for improving the farmland soil has the advantages of avoiding pollution and poisoning of heavy metal and other harmful elements in chemical technological fertilizer, being clean, protecting the environment, maintaining ecological balance, and being capable of effectively improving farmland soil and soil fertility.

Description

A kind of arable soil improvement method

Technical field

The technical field of the invention is the technological innovation of arable soil improvement.

Background technology

The existing method that increases soil fertility mainly is that to use chemical fertilizer be main.Its defective is: the chemical fertilizer contents of heavy metal elements is high, genotoxic potential is strong, seriously polluted, the human carcinogen leads height, very harmful and crops very easily produce dependence ...

Summary of the invention

By with biotechnology instead of chemical technology, avoid in the chemical fertilizer harmful substance such as heavy metal to pollute, poison, clean environment firendly maintains the ecological balance, and can effectively improve arable soil, improves soil fertility.

Technical scheme

Take peasant family as unit, by the mature vermiculture technology of industry, can engulf in a large number by mass rearing earthworm etc. at home, digestion, the degraded harmful substance, can increase by excreta again the insect of soil fertility, in the warm moist region time, concentrated Large-Area-Uniform buries and is put in the field soil, in conjunction with alternate manners such as applications of farmyard manure material, arable soil is implemented improvement, thereby reaching harmful substances such as avoiding in the chemical technology chemical fertilizer heavy metal pollutes, poison, clean environment firendly maintains the ecological balance, and can effectively improve arable soil, improve soil fertility.

Know-why

Earthworm can be decomposed debirs because body contains multiple specific enzymes, helps to solve problem of environmental pollution.Utilize earthworm can absorb micro heavies such as mercury, lead and cadmium in the soil, eliminate heavy metal in soil and pollute.

Earthworm is Omnivore, and it is not eaten except glass, plastic cement, metal and rubber, and all the other are all eaten such as the catabolite of humus, animal wastes, soil bacteria etc. and these materials.Earthworm has a sharp sense of taste, happiness sweet food and tart flavour.Detest bitter taste.Like the feed of thermalization jewelry, expensive clothing and other valuables, particularly voracious to animal food.Food has half to discharge as ight soil by digestive tract approximately.

The sharp what ventilation of earthworm chesson and draining are pulled organic substance into the institute excavation cavity and are made accelerated decomposition, thereby increase the required nutrient component of plant growth.

Earthworm is movable in soil, makes loosing soil, and air and moisture can go deep into being conducive to plant growth in the soil more, can play the effect of improvement soil.

Earthworm can be improved the fertility of soil, earthworm eat into rotten organic matter and a large amount of grogs, form ight soil through digestion and excrete, wherein contain abundant nitrogen, phosphorus, the nutrients such as potassium.

It is very high to utilize earthworm to process the efficient of debirs, such as 100,000,000 earthworms, the 40 tons of debirs of just can eating in a day.

Beneficial effect

If the present invention can popularize application in an all-round way, can effectively avoid in the chemical technology chemical fertilizer that soil environment is caused the ground severe contamination, particularly can avoid the harmful content such as carcinogenic grade in the chemical fertilizer to consist of the potential serious harm in ground to the human life is healthy.

Specific embodiments

(1), take peasant family as unit, by the mature vermiculture technology of industry.

(2), the harmful substance of can nibbling in a large number, digest, degrade such as mass rearing earthworm at home, can increase by excreta again the insect of soil fertilizer.

(3), be chosen in the warm moist region time, concentrated Large-Area-Uniform buries and is put in the field soil.

(4), in conjunction with alternate manners such as applications of farmyard manure material, to arable soil enforcement improvement.

Claims (1)

1. by with biotechnology instead of chemical technology, avoid in the chemical technology chemical fertilizer harmful substance such as heavy metal to pollute, poison, clean environment firendly maintains the ecological balance, and can effectively improve arable soil, improves soil fertility, comprises step:

(1), take peasant household as home unit, by the mature vermiculture technology of industry.

(2), the harmful substance of can nibbling in a large number, digest, degrade such as mass rearing earthworm at home, can increase by excreta again the insect of soil fertilizer.

(3), be chosen in the warm moist region time, concentrated large tracts of land is buried and is put in the field soil.

(4), in conjunction with alternate manners such as applications of farmyard manure material, to arable soil enforcement improvement.
