Abstract
The invention relates to a conditioner for the quick desalination of coastal saline soil, which comprises organic fertilizer, gypsum powder and polyacrylamide, wherein the application amount of the organic fertilizer is 5 to 10 cubic meters/mu, the application amount of the gypsum powder is 5 to 10 cubic meters/mu, and the application amount of the polyacrylamide is 1 to 1.3 kilograms/mu. Aiming at the special demands of sowing and seedling keeping in a coastal saline and alkaline area, the conditioner for the quick desalination of the coastal saline soil is developed, has the advantages of simple operation during use, local production of raw materials, low cost and quick desalination, can also be used for regulating the moisture and nutrients of the soil, maintaining water and soil nutrients, improving the soil and microenvironment of seeds and improving crop yield, and is a novel nontoxic conditioner for soil liquid manure.
Description
Technical field
The present invention relates to a kind of amendment, relate in particular to a kind of amendment for quick desalination of coastal saline soil.
Background technology
China's saline soil distributes also very extensive, and according to the Second National soil survey information statistics of Ministry of Agriculture's tissue, China's saline soil area is 3,467 ten thousand hectares (not comprising coastal tidal).Wherein solonchak is 1,600 ten thousand hectares, and 86.7 ten thousand hectares of alkaline earths, all kinds of salinization, alkali-affected soil are 1,800 ten thousand hectares.That has opened up wasteland plantation in 3,467 ten thousand hectares of salinized soils has about 6,670,000 hectares.According to estimates, still there are 1,733 ten thousand hectares of potential salinization soils in the left and right sides in China, if this class soil can reasonably be developed, China is ensured that 1,800,000,000 mu of arable land red lines are no small contributions.
Existing amendment for the salt affected soil quick desalination, although the improvement soil salt is had certain effect, but its cost is high, troublesome poeration and be not easy to be accepted by the peasant, and it is more shallow especially not to be suitable for coastal saline-alkali area ground water table, the salinity frequently plot that moves up and down.
Summary of the invention
The present invention is directed to existing amendment for the salt affected soil quick desalination, although the improvement soil salt is had certain effect, but its cost is high, troublesome poeration and be not easy to be accepted by the peasant, especially it is more shallow not to be suitable for coastal saline-alkali area ground water table, the salinity frequently deficiency in plot that moves up and down provides a kind of amendment for quick desalination of coastal saline soil.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of amendment for quick desalination of coastal saline soil comprises fertilizer, terra alba and polyacrylamide, the applied amount of described fertilizer is 5 cubic metres/mu～10 cubic metres/mu, the applied amount of terra alba is 5 cubic metres/mu～10 cubic metres/mu, and the applied amount of polyacrylamide is 350,000 g/acres～500,000 g/acres.
The invention has the beneficial effects as follows: the present invention is used for the amendment specific demand that regional sowing is kept a full stand of seedings for coastal saline-alkali of quick desalination of coastal saline soil and develops, simple to operate during use, gather materials on the spot, with low cost, can quick desalination, can also be used for regulating soil moisture, nutrient, conserve water and soil nutrient, improve soil, improve the seed microenvironment, improve crop yield, be a kind of soil liquid manure amendment of Novel non-toxic.
On the basis of technique scheme, the present invention can also do following improvement.
Further, when described polyacrylamide existed with the form of solid, fertilizer, terra alba and polyacrylamide mixed the rear top layer that directly is spread on coastal saline soil.
Further, when described polyacrylamide exists with the form of solution, the water-soluble formation of described polyacrylamide is dissolved with the aqueous solution of polyacrylamide, after mixing, described fertilizer and terra alba be spread on the top layer of coastal saline soil, after being turned in the top layer of coastal saline soil again, irrigate with the aqueous solution that is dissolved with polyacrylamide.
Further, the water-soluble amount of described polyacrylamide is 50 gram/cube water～100 gram/cube water.
Further, described fertilizer is the movement of animal.
Further, the movement of described animal comprises one or several in pig manure, cow dung and the chicken manure.
Further, the planar terra alba of described terra alba for selling on the finishing building materials market.
Further, the granularity of described planar terra alba is 10 microns～50 microns.
Embodiment
Below principle of the present invention and feature are described, institute only gives an actual example and to be used for explanation the present invention, is not be used to limiting scope of the present invention.
The amendment that the present invention is used for quick desalination of coastal saline soil comprises fertilizer, terra alba and polyacrylamide, the applied amount of described fertilizer is 5 cubic metres/mu～10 cubic metres/mu, the applied amount of terra alba is 5 cubic metres/mu～10 cubic metres/mu, and the applied amount of polyacrylamide is 350,000 g/acres～500,000 g/acres.
When described polyacrylamide existed with the form of solid, fertilizer, terra alba and polyacrylamide mixed the rear top layer that directly is spread on coastal saline soil.
When described polyacrylamide exists with the form of solution, the water-soluble formation of described polyacrylamide is dissolved with the aqueous solution of polyacrylamide, after mixing, described fertilizer and terra alba be spread on the top layer of coastal saline soil, after being turned in the top layer of coastal saline soil again, irrigate with the aqueous solution that is dissolved with polyacrylamide.The effect of irrigating again after described polyacrylamide is water-soluble is better.The water-soluble amount of described polyacrylamide is 50 gram/cube water～100 gram/cube water.
Described fertilizer is the movement of animal, and the movement of described animal comprises one or several in pig manure, cow dung and the chicken manure.The planar terra alba of described terra alba for selling on the finishing building materials market, the granularity of described planar terra alba is 10 microns～50 microns.
The below is described in further detail the amendment that the present invention is used for quick desalination of coastal saline soil with specific embodiment.
Example one: cow dung, 10 microns terra alba and polyacrylamide are mixed the formation amendment, and the content of described each composition of amendment is: cow dung is 5 cubic metres/mu, 5 cubic metres/mu of terra albas, 350,000 g/acres of polyacrylamides.7 days prior to seeding, this amendment is spilt uniformly in the earth's surface, then topsoil is carried out rotary tillage; Then carry out flood irrigation according to 30 cubic metres/mu irrigation quantity.After soil is irrigated 7 days, namely before the sowing, can make the topsoil ratio of desalinization reach 40%, be fit to the seed sprouting requirement.
Example two: with 5 cubic metres/mu of cow dungs, 10 microns 5 cubic metres/mu of terra albas, 7 days prior to seeding, spill uniformly in the earth's surface successively, then topsoil is carried out rotary tillage; Polyacrylamide 10 gram/cubic meter is soluble in water, then carries out flood irrigation according to 30 cubic metres/mu irrigation quantity.After applying the coastal saline soil after the present embodiment amendment, can make the topsoil ratio of desalinization reach 40%, be fit to the seed sprouting requirement.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
