Abstract
The invention proposes a kind of preparation methods of environment protection type soil increasing agent.The soil increasing agent is made of modified straw, modified humic acid, plant ash, alginic acid, mannose, zeolite powder and additive.Wherein modified straw is 35~60wt%, and humic acid is 8~17wt%, plant ash is 10~30wt%, alginate is 6~15wt%, mannose is 1~5wt%, zeolite powder is 8~29wt%, additive is 0.007~0.012wt%.Each component content is mass percent.The preparation process that the soil optimizes agent is simple, and raw material sources are extensive, and cost is relatively low, nontoxic.The soil increasing agent is mixed with soil in the proper ratio when use, just have effects that improve and optimize soil function, make gas permeability, the culvert of soil are aqueous, contain the performances such as fertilizer, the property for promoting plant growth to improve all significantly, significantly reduce the loss of fertilizer in soil water evaporation or excessively rising and soil.
Description
Technical field
Desertification soil improvement of the present invention and improvement field, are related to a kind of preparation method of environment protection type soil increasing agent.
Background technique
Soil conditioner is a kind of physics, chemistry and biological property for being mainly used for improveing soil, it is made to be more suitable for planting
Object growth, rather than the material of plant nutrient is mainly provided.Moisture, nutrient are all indispensable in plant growth and development.Moisture
It wanes with nutrient and has become the restraining factors of China's agricultural sustainable development.China is the highest state of applying quantity of chemical fertilizer in the world at present
Family, but the utilization rate of chemical fertilizer only 30% or so, most of to be lost, the problems such as resource of initiation, environment, ecology, becomes increasingly conspicuous,
Adverse effect is caused to agricultural sustainable development.China's level of ground water decline in recent years, desertification, salinization of soil, water quality
The problem of pollution, environmental degradation adjoint generation, in face of the water resources crisis increasingly deepened, the decrement of agricultural water-saving irrigation, chemical fertilizer
Change efficiently using as trend of the times.Existing soil conditioner can be divided into four classes: natural type, synthesis type, naturally with synthesis altogether
Poly- type and bion.This four major class modifying agent respectively has advantage and disadvantage, but generally speaking effect is not satisfactory, it is difficult to meet soil
Improvement requires.For example, some farmland water-saving agent or water-retaining agent, although having the advantages that preferable water-absorbing-retaining, at high cost,
Salt tolerance is poor.In addition, the fertilizer conservation performance of existing water-retaining agent is bad.Patent CN108558559A discloses a kind of soil improvement
Agent, which is made of bentonite, feces of livestock and poultry, mushroom bacteria stick, EM bacteria agent, although can be improved the nutrient of soil,
It is limited to the holding capacity of fertilizer and moisture in soil.Patent CN104087305A discloses kind of soil conditioner and its production
Method, the soil conditioner include following each ingredient, ammonium humate, humic acid potassium part, fine coal ash, agricultural water-retaining agent part, sulphur
Sour ammonium, diammonium hydrogen phosphate, potassium chloride, manganese oxide, zinc oxide part, molybdenum trioxide, the modifying agent are improved the soil, are promoted in water conservation, sand control
Soil fertility etc. has certain effect, but prevents the loss effect of fertilizer in soil little.
Summary of the invention
The present invention is weaker to fertilizer and water tariff collection in order to overcome the problems, such as existing soil conditioner, a kind of disclosed environmental protection
The preparation method of type soil increasing agent, the soil increasing agent can improve and optimize soil function, significantly reduce soil moisture
Evaporation is excessively rising, significantly reduces the loss of fertilizer in soil, makes the gas permeability of soil, contains aqueous, culvert fertilizer, promotes to plant
The performances such as the property of object growth all significantly improve.
The specific technical proposal is:
A kind of preparation method of environment protection type soil increasing agent, the soil increasing agent by modified straw, humic acid, plant ash,
Alginate, mannose, zeolite powder and additive are constituted, the weight ratio of different component are as follows: 35~60wt% of modified straw, humic
8~17wt% of acid, 10~30wt% of plant ash, 6~15wt% of alginate, mannose 1-5wt%, 8~29wt% of zeolite powder,
0.007~0.012wt% of additive；It is prepared using microwave heating, heating power 800-1200W, reaction time 8-
14min, when preparation, needs plus water, and amount of water is 0.2-0.8 times of stalk quality before modified.
Further, additive used are as follows: by N-N methylene-bisacrylamide, ammonium persulfate, zinc nitrate and dodecane
Base sodium sulfonate is according to the mixture that mass ratio is that 6:2:2:0.01 is matched.
Further, the method for modifying of above-mentioned modified straw is: stalk being carried out pulverization process, smashed granularity first
Range 50-100 mesh, is then added sodium carbonate liquor, and sodium carbonate liquor concentration is 30wt%, the quality of stalk and sodium carbonate liquor
Than for 1:2；It is impregnated, takes out naturally dry after soaking time 4h.
The stalk is the mixing of one or both of corn stover, rice straw.
The alginate is the mixing of sodium alginate, alginic acid ammonia or potassium alginate one or more.
The granularity of the zeolite powder is 30-50 mesh.
The invention has the benefit that the increasing agent can not only significantly improve soil culvert is aqueous and absorption organic fertilizer etc.
The ability of a variety of fertilizer, moreover it is possible to which the gas permeability for improving soil prevents the hardened of soil and desertifies.Soil optimization agent can change
The physical behavior of soil significantly reduces soil water evaporation or excessively rising, substantially reduces the loss of fertilizer in soil, therefore
It can be widely used for the fields such as improvement and the improvement of normal soil or even desertification soil.
