Abstract
The invention relates to a method for improving saline-alkali soil by utilizing residual rural waste, and belongs to the technical field of soil improvement. The saline-alkali soil is improved by utilizing materials such as residual straws in rural areas, branches, abandoned fungus bran and the like; the residual materials are crushed to obtain crushed materials; the crushed materials are mixed with the saline-alkali soil and loam soil in certain proportion to obtain a mixture; the mixture is laid in a to-be-planted area with a laying thickness determined according to a planting variety; and thoroughly-decomposed poultry manure and livestock manure are applied to the bottom of the mixture. According to the method, the fertility of the soil can be remarkably improved and the environment is cleaned while the structure of the saline-alkali soil is improved.
Description
Art:
The invention belongs to technical field of land improvement, particularly a kind of measure utilizing the rural surplus thing transformation salinity ground soil structures such as stalk, branch, waste mushroom leftover.
Background technology:
Saline-alkali soil resource, as a type of land resources, is worldwide widely distributed, and is also a kind of important land resources.Along with population growth, Cultivated Land Area Decrease, a large amount of forest, meadow, wetland are opened up wasteland as ploughing, and carry out intensive farming, destroy original vegetation and soil structure, cause saline Land to increase the weight of.These soils are becoming abandons ground, and this has seriously constrained local farming and animal husbandry and socioeconomic development, and administering saline land becomes global problem.Very large difference is also existed to the method for alkaline land improving, just the progress of current home and overseas, mainly concentrate on Salt tolerant plants, cover the research aspects such as improvement and chemical addition agent.
Publication number is that a kind of agricultural stalk that utilizes that patent describes of CN104285533A improves the method for alkaline land soil, the method utilizes maize straw and wheat bran to obtain medium for raw material, medium is loaded Polythene Bag, after sterilizing cooling, inoculated and cultured is ripe to mycelium, in the ditching of lay-up period arable land, the mycelium cultivating maturation is taken off bag to be placed in ditch, earthing compacting is watered, gather ripe edible mushroom, the method utilizes agricultural stalk waste resource to plough at lay-up period and sows mycelium, increase arable land N P and K and the content of organic matter, reduce surface soil alkalinity, be of value to crop growth, but the method is subject to seasonal restrictions, varieties of plant is single, can not transformation salinity ground soil structure.
Publication number be CN103771911A patent describes a kind of method utilizing industrial silico-calcium board waste material to produce moderate-element acidic soil conditioner, the method is using calcium silicate board with microporous, white clay, dolomite etc. and helps additive A and B as mixed material, by ball milling, dry, processing and forming, calcination activation, cooling, pulverize, obtained mineral matter nutritional type acidic soil conditioner, the adjustable acidity of acidic soil conditioner product prepared by the method or the physicochemical property of alkaline land soil, promotes medium trace element level in soil.But the method complex manufacturing technology, cost is high, can not improve alkaline land soil structure, not have persistence.
Publication number is a kind of method that patent describes soil melioration of CN103288555A, the method adopts animal wastes, crop stalk ashes, six or six powder, the diamino fermented to make, the method can provide a large amount of organic matters, improvement soil structure, improve saline land growth quality, but the method has newly increased six or six powder of forbidding and has utilized rural surplus thing few, and persistence is low.
Publication number is that CN102217438A patent describes a kind of saline and alkali land improvement method, the pH value this method solving existing alkaline land soil is not suitable for the technical problem of plant growth more than 10, but the method needs repeatedly to carry out, and does not have persistence, utilize material single, to soil structure no effect.
Publication number be CN102077710A patent describes a kind of method utilizing the improvement saline land of bio-organic fertilizer, the method house refuse is carried out classify process utilize refuse more than kitchen wherein, plant and animal residues, wastewater treatment after mud dispose reason through compost, can increase the mineral nutrient such as the soil organic matter in saline land and alkali-hydrolyzable nitrogen, rapid available phosphorus, available potassium, full nitrogen, full phosphorus and full potassium significantly, but the method does not relate to the rural surplus things such as stalk, branch, waste mushroom leftover and poultry and livestock excrement.
Saline-alkali Field Control is global problem, and along with the development of science and technology, increasing additive is applied in alkaline land improving, and Rhoades proposes to add calcareous material to the method improvement of the sodium or application acid or acidic materials of replacing soil colloids absorption.The former Soviet Union utilizes basic industry by product calcium chloride, the improvement soda saline alkal soil such as rubber industry by product sulfuric acid and alkaline earth.Sharma research and utilization pyrite, as the modifying agent of cultivation alkali soil, reduces soil pH value.The people such as Allison utilize Prof. Du Yucang high polymer to improve soil, domestic report utilizes the accessory substance ardealite producing high concentration phosphate fertilizer, the citric acid waste that Citric Acid Plant is discharged, eliminates the accessory substance desulfurated plaster in the desulfurizing device new technology of the pollutant oxysulfide produced in coal burning process and the improvement such as residue natural pond slag, the natural pond liquid alkaline earth after producing biogas.The people such as Wang Wenjie have done detailed analysis to after application high molecular polymer (HPMA with PAA etc.) improvement soil physics and chemistry structure to the effect of the different plant of plantation.
Summary of the invention:
The object of the invention is to utilize rural surplus discarded object to improve alkaline land soil structure, rural area produces a large amount of stalk, branch, waste mushroom leftover and poultry and livestock excrement every year, these residue serious environment pollutions, and saline land is due to compact structure, salt alkali content is high, plant is difficult to growth, and these rural surplus things add in saline land and effectively can improve soil structure after pulverizing, and utilize plant root growth.
In order to achieve the above object, the technical solution used in the present invention comprises: first collect the residues such as stalk, branch and waste mushroom leftover, carry out pulverization process, these crushed materials mix according to a certain percentage with saline-alkali soil, loam, mixture is laid on plan growing area, and laying depth is determined according to varieties of plant, applies the poultry and livestock excrement after becoming thoroughly decomposed bottom mixture, significantly fertility can be increased, cleaning ambient while improving alkaline land soil structure.
Rural surplus thing comprises stalk, branch, waste mushroom leftover and poultry and livestock excrement.
The rural surplus things such as stalk, branch, waste mushroom leftover will be pulverized, and poultry and livestock excrement will become thoroughly decomposed.
The mixed proportion of the stalk after pulverizing, branch, waste mushroom leftover and saline-alkali soil, loam is 1:1:1.
Mixture laying depth, for shallow root system plants such as corn, Chinese sorghum, vegetables, thickness 20-30cm, the dark root system plant thickness 40cm such as trees.
The poultry and livestock excrement thickness 10cm become thoroughly decomposed bottom mixture.
Advantage of the present invention is:
1, the present invention utilizes the rural surplus things such as stalk, branch, waste mushroom leftover, poultry and livestock excrement in a large number, improves rural surplus waste utilization rate, can administer rural environment simultaneously.
