Abstract

The invention relates to a strawberry culture medium, in particular to a special soilless culture medium for strawberries. According to the special soilless culture, an upper-layer medium is prepared by mixing green algae, spirogyra, zinc ash, manganese ash and silica fume, a middle-layer medium is prepared by mixing rotten wood, brewer's grains and apple pomace, and high-phosphate slag powder is taken as a bottom-layer medium. Waste is taken as a medium raw material, waste natural resources are sufficiently utilized, environmental pollution is reduced, the special soilless culture medium contains higher trace elements such as zinc, manganese and the like and meets the demands of strawberries for microorganism elements, the medium continuously and slowly releases nutritional ingredients in the planting process, accordingly, the phenomena of overnutrition at the earlier stage of strawberry planting and nutrition deficiency in the later planting period of the strawberries cannot be caused, the nutrition demand of the strawberries in the whole growth period is met, outside fertilization is not required in the culture process, all that is required is to meet the daily water demand, the medium can rapidly dredge water, microbial source germination of powdery mildew, gray mold and anthracnose is avoided, root growth of the strawberries can be promoted, a protective layer is formed on the surfaces of root systems, and the disease-resistant capability of seedlings is improved.

Description

A kind of making method of strawberry soilless culture dedicated substrate

Technical field

The present invention relates to a kind of cultivated strawberry matrix, be specifically related to a kind of strawberry soilless culture dedicated substrate.

Background technology

Strawberry is rich in amino acid, fructose, sucrose, glucose, citric acid, oxysuccinic acid, pectin, carotene, VITMAIN B1, Lin Suanna Vitamin B2 Sodium Phosphate, nicotinic acid and mineral calcium, magnesium, phosphorus, iron etc., and these nutrient substances are to good promoter action of having grown.Can eat raw, also can be made into jam and preserve for a long time.Strawberry nutrition is worth high, containing enriching vitamins C, effect of helpful digestion, meanwhile, strawberry can also consolidate gums, fresh breath, moist throat, there is anticancer effect, at present due to State owned land resource scarcity, cultivation technique without soil rises gradually, soilless culture mainly relies on cultivation matrix to provide nutrition to strawberry, soilless culture is generally divided into inorganic ecotype soilless and organic ecological soilless culture, namely inorganic ecotype soilless adopts nutritive medium to carry out irrigated crop, this method not only cost is high, manage also cumbersome, the vegetables and fruits class nitrate content of planting out is high, environmental pollution, consume energy high, organic ecological soilless culture adopts SOLID ORGANIC substratum to cultivate vegetables and fruits, this method power consumption is low, convenient management, substratum plays vital effect in the course of cultivation, current substratum generally adopts the peat composed of rotten mosses to be main raw material, because the peat composed of rotten mosses belongs to Nonrenewable resources, because its demand rises year by year, cause matrix cost value higher, if unreasonable configuration matrix component, raise crop is easy to occur underfed phenomenon, and the problem of current this surge capability difference of soilless culture substrate ubiquity, cause later stage liquid manure supply to be discharged to have some setbacks, in the past for a long time, raise crop be easy to occur rotten or dietetic alimentation insufficient.

Summary of the invention

The object of the present invention is to provide a kind of cheap, strawberry soilless culture dedicated substrate that convenience of drawing materials, nutritional sufficiency, seepage force are strong.

The technical solution used in the present invention is, a kind of making method of strawberry soilless culture dedicated substrate, and it comprises following steps:

1) green alga and water silk floss are dried to water content lower than 8%, dried green alga and water silk floss are crushed to 100-120 order, with zinc gray, manganese ash, the grey mixing granulation of silicon, granulated pellet particle diameter is 0.03-0.05cm, obtains the first composite grain;

2) corruption wood, brewer's grains, apple residue admixture ferrous sulfate are mixed, its humidity is made to be 45%-50%, be stir under the environment of 35 DEG C-38 DEG C in temperature, mixing speed is 30-40r/min, stir after 8 hours, the mixture after stirring is put into heatable adobe sleeping platform and bury fermentation 25-28 days, obtain fermentation materials;

3) material after fermentation is made the particulate state that particle diameter is 0.2-0.4cm, obtain the second composite grain;

4) high phosphorus-slag-powder is broken to the training particulate state that particle diameter is 0.8-1cm;

5) using high phosphorus slag particle as bottom matrix, the chopping of fresh Pericarpium Musae is mixed with the second composite grain, spreads and to be layered on high phosphorus slag particle upper strata as middle level matrix, finally spread paving first composite grain and obtain strawberry cultivation soilless substrate, as overlayer matrix.

The wherein height of bottom matrix: the height of middle level matrix: the height of overlayer matrix is 2:1:0.5.

The present invention chooses waste as base starting material, make full use of nature waste resource, reduce environmental pollution, containing higher zinc, the trace elements such as manganese, meet the demand of strawberry to microorganism element, planting process mesostroma is by continuous slow releasing idiotrophic composition, there will not be overnutrition at strawberry cultivating and there will not be the phenomenon of nutritive deficiency in the strawberry cultivating later stage early stage, meet strawberry whole vegetative period to the demand of nutrition, need not extraneous apply fertilizer in cultivation, only need meet daily water requirement, matrix can dredge moisture very soon, matrix there will not be wet phenomenon, avoid Powdery Mildew, the bacterium source of gray mold and anthrax is sprouted, strawberry root growth can be promoted, protective layer is formed on its root system surface, improve seed disease resistance ability, strawberry fruit-setting rate can reach more than 85%, Mean Fruit Weight is at about 45g, sugar degree can reach about 15%.
