Soilless culture is fertile with itself intrinsic joint, water saving, laborsaving, economize medicine, high yield, the advantage such as of fine quality, clean, become the important content of facilities horticulture and the principal mode of horticultural crop factorial praluction.But the nutrient solution soilless culture method production cost of application is very high usually, and be difficult to solve to the pollution problem of environment.And organic ecological soilless culture technology replaces soil with Different Stroma, nutrition liquid irrigation root system of plant that also need not be traditional, but directly add with organic solid-state fertilizer a kind of cultivation technique without soil that clear water impels plant growth.Its advantage is very outstanding, namely improves the yield and quality of crop, reduces pesticide dosage, water saving saves fertilizer, the pure health of product, saves both labour and money, uncultivated area can be utilized to produce vegetables etc.Therefore, yield of vegetables, oil recovery enhancement can be improved by this technology, produce the vegetables of high-quality even " organic vegetable ", reduce environmental pollution simultaneously.
Spinach (SpinaciaoleraceaL.) belongs to Chenopodiaceae spinach and belongs to, and extensively planting in China town and country spring, autumn, season in winter 3, is a kind of important green vegetable of China and export vegetable.Spinach high nutritive value, is rich in vitamin B1, vitamin B2, vitamin C, carotin, protein, folic acid, and the mineral matters such as Yi Jitie, calcium, phosphorus, are described as " kings in vegetables " by Arabic.But spinach is as a kind of leaf vegetables, very easily accumulate nitrate and oxalic acid, nitrate can make people suffer from methemoglobinemia after taking in human body.Meanwhile, nitrate is the precursor of Carcinogenic Nitrosamines, easily brings out digestion canceration.And oxalic acid is a kind of antinutritional factor, the validity of mineral element calcium, magnesium and zinc etc. can not only be affected, and easily cause calcium oxalate kidney stone.In Conventional process, applying in a large number of nitrogenous fertilizer makes nitrate content severe overweight in spinach.But go back the effective implantation methods of neither one at present and can overcome traditional field planting spinach, in a large amount of, apply the problem that nitrogenous fertilizer produces nitrate content severe overweight.
Therefore, set up a set of spinach high yield, high-quality and efficient soilless culture method seems very necessary and important.
Summary of the invention
The object of the present invention is to provide a kind of spinach organic ecological soilless culture method.This method adopts organic ecological soilless culture method, effectively can reduce chemical fertilizer, especially the amount of application of nitrogenous fertilizer, thus significantly can reduce the nitrate content of vegetables, improves other index of quality of vegetables simultaneously.
For solving the problem, technical scheme of the present invention is: a kind of spinach organic ecological soilless culture method, comprises the following steps:
1) matrix is prepared: be after 2.0 ︰ 3.0 ︰ 3.0 ︰ 2.0 mix by the peat composed of rotten mosses, wood sawdust, rice husk by volume with vermiculite, chicken manure is added again and each 15kg and 8kg of cake fertilizer mixes by every cubic metre, obtain matrix, and matrix is inserted in substrate grooves respectively;
2) seeding and seedling raising: select spinach seed of the same size, first carries out surface sterilization 10min with the liquor natrii hypochloritis that volume fraction is 5%, and after fully rinsing by deionized water, by planting seed in substrate grooves; Wherein, seeding quantity is 3.0 ~ 5.0kg/667m
2;
3) thinning: carry out thinning when seedling grows to 2 ~ 3 true leaves, spacing in the rows is 5 ~ 8cm;
4) later maintenance: comprise to carry out after thinning water, apply fertilizer, the extermination of disease and insect pest, wherein, described in water and to water depending on water supply in media situation, every 3d soil moisture content quick analyser checks water supply in media situation, keeps Relative water content 70 ~ 80%;
Described fertilising adopts on a small quantity repeatedly, the mode of split application, and thinning terminates rear organic vegetable special fertilizer and topdresses, and by every m
3matrix adds 2kg organic vegetable special fertilizer, regards as thing growing state later and topdresses 2 ~ 3 times; The described extermination of disease and insect pest is that each cultivating groove arranges 2 trapping points with fly paper trapping Liriomyza adult; Eliminate aphis that times liquid spraying is anti-eliminates aphis with mass fraction to be 1% matrine vegetable insecticide be by volume 500 ~ 1000 times of liquid are anti-; Be 3000 times of liquid spraying control Liriomyzas by volume with the abamectin emulsifiable concentrate that mass fraction is 1.8%; Containing the phase at beet armyworm egg hatching, is 200 times of liquid bacillus thuringiensis,Bt missible oil spraying controls by volume ratio; Prevent virus diseases with the capsicum water that mass fraction is 0.5%; With the solution that copper sulphate, quicklime, water are 1 ︰ 1 ︰ 200 in mass ratio, spray 2 ~ 3 times continuously and control fungal disease.
Above-mentioned steps 1) in, the matrix in substrate grooves irrigates in sowing first 1 day use water.
Above-mentioned steps 1) described in wood sawdust and rice husk become thoroughly decomposed through high temperature, and vermiculite is placed in volume fraction be 15% liquor natrii hypochloritis soak 30 minutes after and rinse well with clear water, then by the peat composed of rotten mosses, wood sawdust, rice husk and vermiculite by volume 2.0 ︰ 3.0 ︰ 3.0 ︰ 2.0 mix;
Above-mentioned steps 1) in, it is after the potassium permanganate liquid mixing sterilization of 0.1% that matrix is placed in mass fraction, then tiles in substrate grooves.
