Abstract
The invention relates to a plant soilless culture medium manufacturing method, in particular to a manufacture method of a plant soilless culture medium with environmental protection and high efficiency. Mainly aiming at the defects of poor economy and feature of environmental protection of the prior plant soilless culture medium made of chemical raw material, the invention provides the plant soilless culture medium manufacturing method which has low cost and is made of raw material which is environment-friendly and is easy to obtain. The plant soilless culture medium is obtained by adopting leftovers as the raw material, then adding decomposer and water and adding water after the mixture stands and ferments in the absence of oxygen.
Description
Technical field
The present invention relates to a kind of preparation method of soilless culture medium for plant, relate in particular to a kind of preparation method of soilless culture medium for plant of environment-friendly high-efficiency.
Background technology
Soilless culture medium for plant is widely used in field of planting, it is workable, what be suitable for planting is flexible and changeable, and economic environmental protection, in today that per capita cultivated land's scale day by day reduces, soilless culture has brought new sustainable development pattern to agricultural development, but because the manufacturing process of soilless culture medium for plant requires height, does not have the foster popularization of earth culture to plant and cause adverse influence.
As the manufacture method of a kind of Chinese publication number plant culture matrix that is CN1439253 and the plant culture matrix that makes of method thus, this method may further comprise the steps: (A) carry out polycondensation reaction and be mixed with resin solution formaldehyde, urea, hexa, glycerine and absolute ethyl alcohol are mixed; (B) foaming agent solution of above-mentioned resin solution with preparation in advance mixed, supply in the frothing machine and bubble, generate foam matrix; (C) above-mentioned foam matrix is added to it is solidified and demoulding, oven dry; (D) foam matrix of oven dry is immersed preparation in advance be used for provide the immersion liquid of fertility to soak, dry then and (E) foam matrix of drying in (D) step cut into slices.
Present most soilless culture medium for plant adopts industrial chemicals to process, form and the akin culture environment of soil, but these class methods have two kinds of shortcomings: 1) chemical raw material is more expensive, makes production cost significantly increase, and compares with traditional soil plantation and there is no remarkable economy; 2) use of chemical raw material has brought secondary pollution, makes the feature of environmental protection of soilless culture reduce, and disagrees with the original intention of soilless culture.
Summary of the invention
The present invention mainly is soilless culture medium for plant economy and the low shortcoming of making at present use chemical raw material of the feature of environmental protection, invents a kind of cheap, raw material environmental protection and the preparation method of a kind of soilless culture medium for plant of being easy to obtain.
Above-mentioned technical problem of the present invention is implemented by the following technical programs:
The preparation method of soilless culture medium for plant, it may further comprise the steps:
A) using after the meal, remaining food, placed under sunlight or the ultraviolet light and shone 3～6 hours before rotten as raw material;
B) add decomposer and water and be modulated into pasty state then, water content is at 70～80wt%;
C) above-mentioned pasty state raw material anoxic was left standstill 10～20 days, the product that obtains is called the meal element;
D) in above-mentioned meal element, add 1000～2000 times the water of calculating by weight, obtain soilless culture medium for plant.
The preparation method of above-mentioned soilless culture medium for plant, as preferably, in the described steps A, raw material places sunlight under and shone 5 hours before rotten.The illumination sterilization effects is better than adopting the effect of ultraviolet sterilization, and energy savings, helps environmental protection.
The preparation method of above-mentioned soilless culture medium for plant, as preferably, among the described step B, decomposer is Aspergillus flavus or green mold bacterium.
The preparation method of above-mentioned soilless culture medium for plant, as preferably, among the described step B, the water of adding is neutral sanitary wastewater or neutral industrial wastewater or running water.Adopt neutral waste water, both can improve the availability of discarded object, improved environment protecting, increased the nutrient that is beneficial to the plant growth simultaneously.
The preparation method of above-mentioned soilless culture medium for plant, as preferably, the anoxic among the described step C leave standstill for: adopt airtight container that the pasty state raw material together is sealed in the container together with the part air.Contain the sealing of part oxygen, make fermentation process in aerobic environment, carry out earlier, in oxygen-free environment, carry out then.
The preparation method of above-mentioned soilless culture medium for plant as preferably, among the described step D, adds 1000 times the water of calculating by weight in above-mentioned meal element.Medium after the dilution is guaranteeing under the prerequisite that crop grows up healthy and sound, and helps the growth of crop root and absorbs nutrient.
In sum, the present invention compares with prior art and has following advantage:
1. the raw material of Cai Yonging belongs to discarded object, and is therefore totally with low cost;
2. owing to consumed raw material fully in manufacturing process, and manufacturing process adopts sealing device, so manufacturing process is than environmental protection;
3. compared with prior art, various micronutrient levelss are higher in the medium, help the content of material height that crop grows up, and cultivation effect is good.
