Abstract
The invention discloses a method for improving saline-alkali soil by rice hull micro-capsule water permeation. The method is characterized by comprising the following steps of: digging the saline-alkali soil in a depth of 40 to 60 centimeters, paving a layer of diaphragm below the dug saline-alkali soil to prevent underground saline or alkali substances from returning to the improved saline-alkali soil, and culturing the improved saline-alkali soil filled with rice hull to form a ridge table with width of 80 to 150 centimeters and height of 30 to 50 centimeters and a drainage ditch with depth of 40 to 60 centimeters. The rice hull is used as a soil water permeation substance, micro water capsules are easily formed in the cavity of the rice hull, and the water capsules absorb the saline-alkali components in the soil and have the functions of loosening the soil and cutting off soil capillaries, so that salts are quickly leached and discharged to the ditch; and the rice hull easily forms an acidic substance in the soil to neutralize alkalinity of the saline-alkali soil and reduce the pH value of the soil, so that the soil is favorable for the growth of plants. The method is simple and low in cost.
Description
Technical field
The present invention relates to the improvement of salt affected soil, particularly the method for the permeable improvement saline-alkali soil of rice husk micro-capsule.
Background technology
At present, the method kind that the saline land is administered is a lot, the main employing filled sand, the coal ash slag, straw, the branches and leaves of plant etc. are as the soil permeability thing, make hard saline-alkali soil granular structure, loosing soil becomes, make in the saline-alkali soil acceleration of salt drench, the disclosed alkaline land by making leakage on earth's surface soil improvement method of Chinese patent, publication number CN101473718 adopts the method for beating vertical shaft, and saline-alkali soil face of land detritus soil layer and the close soil layer of matter are made leakage, make the salt buck after drenching with rain, permeate the ground in the aquifer sand layer, effectively reduce soil property saliferous alkali content, this technology up-front investment is big, the cost height, the difficult popularization.
Summary of the invention
The objective of the invention is very there is deficiency in existing reclamation of salinep-alkali soil technology, the method for the permeable improvement saline-alkali soil of a kind of rice husk micro-capsule is provided.
The permeable improvement saline-alkali soil of rice husk stalk micro-capsule of the present invention, its raw material is formed and proportioning following (by volume)
Rice husk 10～30%
Saline-alkali soil 70～90%
The permeable improvement saline-alkali soil of rice husk micro-capsule of the present invention, it is characterized in that earlier saline-alkali soil being dug dark 40～60 centimeters, spread one deck plastic diaphragms below, prevent to return on underground salt or the alkaloid substance in the saline-alkali soil after improveing, with the improvement saline-alkali soil of dosing into rice husk, earthing up into ridge platform width is 80～150 centimeters, and ridge platform height is 30～50 centimeters, and the ridge platform pushes up that the degree of depth is 40～60 centimeters at the bottom of the drain ditch.
The present invention improves its step of saline-alkali soil method:
A, get saline and alkaline soil sample, detect the content of salt in the soil, measure pH value;
B, to get new rice husk standby;
C, by volume doses rice husk in the broken saline-alkali soil, and it is even to carry out mechanical agitation, with the saline-alkali soil of improvement, spreads out go back to the original place again, earths up into the ridge platform, carries out smooth;
D, to the saline-alkali soil of improvement, irrigate, irrigated once in per 3～5 days, need to irrigate 5～10 times, the composition of salt in the soil is drenched, from soil, flow in the drain ditch, make that the content of salt is reduced to the cultivable growing environment needs of plant in the soil, pH value reaches 7.5～8.5 and gets final product.
Beneficial effect of the present invention:
(1) utilization of crops rice husk refuse, reduce cost,
(2) the rice husk cavity easily forms miniature water pocket, and water pocket has salt and alkali component effect in the soil of absorption,
(3) have chesson, cut off soil capillary, good water permeability,
(4) make the acceleration of the salt of saline-alkali soil drench, flow in the drain ditch and discharge,
(5) rice husk easily forms acidic materials in soil, comes neutralized salt alkaline earth meta-alkalescence, reduces P in soil H value meta-alkalescence, favourable plant growing.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples
Fig. 1 is the permeable improvement saline-alkali soil of an invention rice husk tangerine bar micro-capsule ridge platform drain ditch profile
Among the figure: the saline-alkali soil of 1 improvement, 2 rice husks, 3 ridge platforms, 4 drain ditchs, 5 barrier films, 6 non-improvement soil layers.
Embodiment
Saline-alkali soil shown in Figure 1 digs dark 40～60 centimeters, and shop one deck plastic diaphragms 5 below, prevent to return in the saline-alkali soil 1 of improvement on the salt of underground non-improvement soil layer 6 or the alkaloid substance.
With the saline-alkali soil of dosing into the improvement of rice husk 21, earthing up into ridge platform 3 width is 90 centimeters, and ridge platform 3 height are 50 centimeters, and it is 50 centimeters that ridge platform 3 pushes up 4 end of the drain ditch degree of depth.
Embodiment:
The permeable improvement saline-alkali soil of rice husk stalk micro-capsule, its raw material is formed and proportioning following (by volume)
Rice husk 15%,
Saline-alkali soil 85%.
Its step of method of improvement saline-alkali soil:
A, get the content that saline and alkaline soil sample detects salt in the soil, measure pH value;
B, to get 15 cubic metres on rice husk standby;
C, by volume with 15 cubic metres rice husk, dose in the saline-alkali soil of 85 cubic metres of fragmentations, it is even to carry out mechanical agitation, the saline-alkali soil with improvement spreads out go back to the original place again, earths up into the ridge platform, carries out smooth.
D, to the saline and alkaline soil of improvement, irrigate, irrigated once in per 3～5 days, need to irrigate 5～10 times, salt component in the soil is drenched, go into the drain ditch from interflow, make that the content of salt is reduced to the environment that plant can be cultivated growth in the soil, pH value reaches 7.5～8.5, gets final product.
