Abstract

The invention discloses a cucurbit and vegetable seedling organic compound substrate prepared by utilizing vinasse and a production method thereof. The volume ratio of components after being thoroughly decomposed is vinasse:biogas residue:crop straw=9:2-4:1-2. After the raw materials are subjected to raw material collection, smashing, pretreatment, thorough decomposition, substrate preparation and quality inspection procedures, the cucurbit and vegetable seedling organic compound substrate prepared by utilizing the vinasse can be obtained. The prepared substrate is strong in water retention, good in gas permeability and rich in nutritional ingredients, contains no inorganic matrix, can promote absorption and utilization of cucurbit and vegetable seedlings on water, fertilizers and gas, enhances stress resistance of the seedlings, is beneficial for seedling strengthening and full seedling stand, and can completely replace substrate products on markets and with peat as a main raw material. At present, the peat is a non-renewable resource and is high in price and nonuniform in distribution, so that the substrate prepared by the method not only can protect the resource, but also reduces the seedling culture cost.

Description

A kind of melon raise seedling organic composite substratd and production method of utilizing vinasse preparation
The application be for the applying date be 2013-2-22, application number: 201310055659.2, denomination of invention: a kind ofly utilize the melon raise seedling organic composite substratd of vinasse preparations and dividing an application of production method.
Technical field
The present invention relates to modern installations agriculture field, be specifically related to a kind of melon raise seedling organic composite substratd that utilizes vinasse preparation, also relate to a kind of production method of utilizing the melon raise seedling organic composite substratd of vinasse preparation.
Background technology
As far back as U.S.'s hole plate seedling growth technology that first begins one's study sixties in 20th century, in the agriculture developed country of America and Europe, promote the wider application subsequently.Early 1980s, equipment and the technology of industrial seedling rearing successively introduced on the ground such as China Beijing, Guangzhou, Shanghai, and grow seedlings of vegetable is realized specialization, commercialization and mechanize.The development of hole plate seedling growth, has changed vegetables traditional mode of production mode and planting system, has promoted the development of modern installations agricultural.
Soilless culture, as the core technology of industrialized agriculture, be unable to do without basic substance---matrix.Matrix plays fixedly seedling or plant in industrial seedling rearing, and supply seedling or plant be with moisture and nutrient, so the quality of its quality directly determine the to grow seedlings height of quality product.At present the substrate products of countries in the world is mainly with the mixed-matrix of the peat composed of rotten mosses and perlite or vermiculite compositional.Yet peat composed of rotten mosses resource-constrained, price are high, skewness, and peat composed of rotten mosses quality has downward trend year by year in recent years, and inorganic matrix is difficult to after using process, and environment is caused to severe contamination, in the urgent need to developing new substrate products.
Based on considering to environment protection with for market provides localization matrix of high quality and at a reasonable price, utilize the organic solid castoff producing in industry, agricultural to produce substrate products, not only turn waste into wealth, also can realize the localization of matrix, reduce seedling cost.Organic solid castoff is of a great variety, study more and have a better DEVELOPMENT PROSPECT mainly contain cotton seed hulls, cotton stalk, straw, Pericarppium arachidis hypogaeae, mushroom slag, carbonization rice husk, saw dust, sugared slag, reed etc.Chen Zhende etc. cross the composite interstitial substance of the preparations such as cotton seed hulls, pig manure, slag ash, alditol slag, vermiculite of mushroom with endemic species, at solanaceous vegetables, melon, leaf vegetables, test respectively.Jin Yizhu has carried out the research of rice straw to tomato sprout quality influence.Also have abroad many research, Chong adds the cultivation of plants tests such as skunk bush that apple residue carries out 2 years in matrix.These organic wastes, after biological fermentation is processed, can become the raw material of seedling medium, and the seedling medium being mixed by a certain percentage substitutes the peat composed of rotten mosses production that is used for growing seedlings to some extent.
Along with the development of industrialized agriculture, seedling medium demand will further expand.Utilize organic solid castoff to produce seedling medium, not only for organic solid castoff resource utilization, matrix and high value added utilization provide new way, solve solid waste problem of environmental pollution, and to promoting the development of industrialized agriculture, and new industry---Sustainable development, the prosperity substrate products commerce and trade economy of matrix industry have extremely important effect.
Summary of the invention
One object of the present invention is to provide a kind of melon raise seedling organic composite substratd, and this matrix can promote melon dish seedling to the absorption of water, fertilizer, gas and utilization, strengthens the resistance of seedling, is conducive to strong sprout, Qi Miao.
A further object of the invention is the preparation method who has been to provide a kind of melon raise seedling organic composite substratd, and method is simple, easily goes, and is suitable for scale operation.
Compared with prior art, the present invention adopts following technical measures:
A melon raise seedling organic composite substratd that utilizes vinasse preparation, the volume ratio after each component is become thoroughly decomposed is:
