Description

A kind of production method of flowers and trees Nutrition Soil
Technical field
The present invention relates to flowers and trees planting technology field, especially a kind of production method of flowers and trees Nutrition Soil.
Background technology
With the rapid development of economy, the demand of flowers and trees is increasing, flowers and trees need Nutrition Soil in cultivation, very The complex manufacturing process of the Nutrition Soil of multiple types, cost are higher.
China's agricultural biomass stalk resource enriches, and stalk annual output is up to more than 800,000,000 tons.Stalk is mainly using direct at present The modes such as returning to the field and simple burning carry out processing disposition.Although straw directly returning to field can effectively improve the soil organism, improve Soil texture plays the role of retain water and nutrients, but straw directly returning to field organic matter degradation is rapid, easily causes CH4And C02Isothermal chamber A large amount of discharges of gas.It is simple simultaneously to burn the huge waste for then not only causing resource, also cause serious atmosphere polluting problem, Air quality is seriously affected, annual straw burning causes multiple cities that thick weather occurs.At biomass straw charing at present Reason is just gradually being accepted and is favoring as a kind of processing mode of novel environment friendly.
Sewage treatment plant's scale in China is increasing, and quantity is more and more, the municipal sludge amount supervened It increases considerably.The sludge annual output in China alreadys exceed 40,000,000 tons at present.History, it is economical due to, China's sewage Treatment plant less focuses on the processing of sludge, there is the phenomenon that " the light mud of heavy water " in planning.The end sludge that sanitary sewage generates Processing disposition, either fund input or technical support cannot all make all sludge obtain the appropriate processing of safety. It is shown according to investigation, most municipal sludge is all simple sanitary landfills and land use, a series of so as to cause Ecological environment problem.
Meanwhile there is also some problems for the processing of the feces of livestock and poultry of rural area.The a large amount of heaps of feces of livestock and poultry in many areas Product pollutes environment.
Invention content
The technical problem to be solved by the present invention is to：Present invention proposition is a kind of to utilize excess sludge in domestic sewage plants, crops Stalk, feces of livestock and poultry are raw material, make flowers and trees Nutrition Soil, solve the recycling and environment of excess sludge, agricultural crop straw The problems such as pollution.
The technical solution adopted by the present invention to solve the technical problems is：A kind of making side of flowers and trees Nutrition Soil of the present invention The concrete operation step of method is：
1. dry excess sludge in domestic sewage plants and feces of livestock and poultry are crushed, sieving；Crops stalk crushing is sieved；
2. after screening excess sludge, feces of livestock and poultry, agricultural crop straw is according to mass ratio 2~10:10:1 ratio is mixed Close uniform, watering infiltration, aerobic compost, fermentation 30~90 days；
3. fermentate natural air drying, crushing, sieving；Agricultural land soil is air-dried, crush, is sieved；
4. wormcast natural air drying, crushing, sieving；
5. fermentate, agricultural land soil, wormcast and the nutritional agents in mass ratio 5 after sieving:5~10:1:1~3 ratio Example is uniformly mixed, and obtains Nutrition Soil.
The manufacturing process of the nutritional agents is：
1) straw charcoal, bentonite are crushed, crosses 60~120 mesh sieve；
2) straw charcoal, bentonite and humic acid, the granular compound fertilizer in mass ratio 10 after screening:2~4:5:1~2 is mixed It closes uniform；
3) binding agent is added in into mixture, is stirred；
4) material is put into comminutor again, is granulated under the conditions of 80~90 DEG C, nutritional agents is obtained after dry.
The manufacturing process of the straw charcoal is：
1. agricultural crop straw is gathered in, is dried；
2. crops stalk crushing, the sieve of 60~120 mesh excessively after drying；
3. the agricultural crop straw after screening is washed, is put into tube furnace after drying, nitrogen is passed through with the flow of 200ml/min Gas, heating rate are 10~20 DEG C/min, and the constant temperature time that set temperature is 400~600 DEG C is 1~3h, is cooled to room later Temperature obtains straw charcoal.
The manufacturing process of the binding agent is：
1) crop starch is dissolved in water, adds in the concentrated sulfuric acid, stirred 5~10 minutes；
2) liquor potassic permanganate is added in, is stirred 50~60 minutes；
3) sodium hydroxide solution is added in, is stirred 20~30 minutes；
4) borax is added in, is stirred 10~15 minutes；
5) it cools down, obtains binding agent.
The beneficial effects of the invention are as follows：It is raw material using excess sludge, agricultural crop straw, feces of livestock and poultry, makes flowers and trees battalion Soil is supported, the growth for flowers and trees provides the nutriments such as nitrogen phosphorus and organic carbon.The present invention realizes excess sludge, agricultural crop straw Recycling, while the environment that part solves the landfill of excess sludge, agricultural crop straw is stacked and open burning generates is dirty Dye problem.
