[summary of the invention]
The present invention provides the soilless culture method of Fructus Lycopersici esculenti in a kind of greenhouse, combines the advantage of greenhouse production and the advantage of soilless culture,
Significantly improve tomato planting yield, mouthfeel, quality and safety.Technical scheme is as follows:
In a kind of greenhouse, the soilless culture method of Fructus Lycopersici esculenti, comprises the steps:
(1). by the prepartion of land in warmhouse booth, and it is compacted compress soil, then uses the partly mode of burying to excavate cultivation bed,
Cultivation bed excavating depth under earth's surface is 20-30cm, and wide 40-50cm, depending on the length of cultivation bed is according to the concrete size in greenhouse;
Reserving the aisle of 50cm between the most adjacent 2 cultivation beds, spread waterproof cloth in cultivation bed, waterproof cloth is close to cell wall, in cultivation
The edge of groove is spread solid clay brick and is formed the height exposing earth's surface;
(2). carry out disinfection in warmhouse booth sterilization, after first using dichlorvos 1kg and 5-10kg sawdust to be sufficiently mixed according to every mu
It is spread to surface, aisle, disinfecting time 12-24 hour;The Caulis et Folium Oryzae that 4-5kg is dried is layered on ground again, and sawdust 5kg tiles Caulis et Folium Oryzae
Above, topmost place sulfur 1kg, after closing warmhouse booth door and vent, light Caulis et Folium Oryzae and fumigate 12-24 hour;
(3). carry out disinfection sterilization to Flammulina velutiper (Fr.) Sing slag and slag matrix, substrate is wrapped up respectively with thin film, stacks 7-10 days, heap
Put period substrate temperature and reach 70 DEG C, major part fungal disease and Disease can be killed;
(4) on cultivation bed inner waterproofing cloth, particle volume, is filled up less than 1cm3Slag, then fill out the fermentation of 18-20cm thickness
Flammulina velutiper (Fr.) Sing slag, by weight Flammulina velutiper (Fr.) Sing slag and slag ratio are 1:1.5, and lay drip irrigation zone 1-2 bar in stromal surface;
(5), tomato seeds soak after 2 days water planting 20-25 days in husky base, the height of tomato seedling reaches 8cm highly
Field planting;
(6) by tomato seedling by spacing in the rows 60cm, the specification of line-spacing 30cm is planted in cultivation bed, every mu of 1800-2000 strain, and
Putting up support, Fructus Lycopersici esculenti uses goes alone pruning technique, extracts side shoot, in good time flower and fruit thinning, uses the drip irrigation system being equipped with to implement water
Fertilizer nutrition liquid irrigation, when Relative water content is less than 45%, carries out liquid manure nutrition liquid irrigation 5-8 minute, Relative water content
Stop more than 80% irrigating;
(7) tomato growth period management, to prevent and treat epidemic disease, virosis, uses low-toxin farm chemicals preventing and treating seedling stage;One month Fructus Lycopersici esculenti
After starting to bear fruit, focusing on powdery mildew and pest control, use biological pesticide to carry out worm preventing and treating, Fructus Lycopersici esculenti plant height grows to 80-120cm,
Carrying out putting climing, seedling stage should increase nitrogen application in right amount, and fruiting period should increase potash fertilizer usage amount.
Described warmhouse booth more than height 2.5m, warmhouse booth vent and door install fly net;Warmhouse booth surrounding soil dry
Dry, there is gutter.
Described slag is the slag that coal-burning boiler produces, and slag pulverizes the fritter for diameter 0.7-1.3cm;Fermentation Flammulina velutiper (Fr.) Sing slag
Be by broken for needle mushroom ground-slag, tiling after spray water to mushroom slag surface wettability, pile fermentation 25-30 days at normal temperatures.
Described waterproof cloth width 1-2m.
The solid clay brick of cultivation bed edge a size of 240 × 120 × 60mm, the edge layer overlay at cultivation bed is solid viscous
Cob brick, covers solid clay brick block upper surface by waterproof cloth to surrounding stretching, then adds 2 layers of solid clay brick by waterproof cloth compression.
Dropper system described in step (6) uses electronic suction pump or diesel engine to provide pressure irrigation water fertilizer nutrition liquid for power.
Described liquid manure ratio of nutrient solution and use as follows:
Nutritional solution a: potassium sulfate (3~7kg)+ammonium nitrate (2~6kg)+potassium dihydrogen phosphate (0.5~1.5kg)+sulphuric acid
Magnesium (2~8kg)+boric acid 15g+ manganese sulfate 10g+ ammonium molybdate 0.1g+ zinc sulfate 1g+ copper sulfate 0.4g+ iron sulfate
500g+EDTA700g+ is pollution-free tap water 5000kg;
Nutritional solution b: calcium nitrate (8~20kg)+potassium nitrate (3~10kg)+boric acid 15g+ manganese sulfate 10g+ ammonium molybdate
0.1g+ zinc sulfate 1g+ copper sulfate 0.4g+ iron sulfate 500g+EDTA700g+ pollution-free tap water 5000kg;
Nutritional solution a and nutritional solution b is used alternatingly, and seedling stage suitably heightens the ratio of ammonium nitrate, fruiting period suitably heighten potassium sulfate and
The ratio of potassium nitrate.
The cultivation bed of the present invention uses mode of partly burying, and can save the input of material in a large number.The substrate used is divided into 2 layers, ground
All using slag below table, aerial parts substrate is Flammulina velutiper (Fr.) Sing slag, this substrate have bigger porosity, beneficially root system breathing,
Moisture bottom extension and absorption and nutrient.Substrate of the present invention sterilization uses the sterilization of 70 DEG C of high temperature above, mainly kill object for kind
Flos Solani Melongenae leaf disease.Use the method cultivated tomato of the present invention, decrease agriculture chemical usage amount and labour force puts into, tomato yield,
Carbohydrate content and Vc content have had and have increased substantially, and this invention is practical, has good economic worth.
[detailed description of the invention]
Various embodiments of the present invention comprise the steps:
The design of cultivation bed: warmhouse booth more than height 2.5m, warmhouse booth vent and door install fly net;Warmhouse booth four
All antecedent soil moistures, have gutter.First by prepartion of land in warmhouse booth, and it is compacted compress soil.Excavation cultivation bed, plants
Training groove uses mode of partly burying, and under earth's surface, excavating depth is 20-30cm, the groove of wide 40-50cm, and the length of groove is according to greenhouse
Depending on concrete size;The aisle of 50cm is reserved between the most adjacent 2 cultivation beds.Waterproof cloth, waterproof cloth width is spread in cultivation bed
Degree 1-2m, waterproof cloth is close to cell wall, is filled up particle volume less than 1cm in waterproof cloth3Slag.Spread at the edge of cultivation bed
One layer of solid clay brick increases the height of groove, and solid clay brick size: 240 × 120 × 60mm, by waterproof cloth to surrounding stretching lid
Live fragment of brick upper surface, and add 2 layers of solid clay brick again by waterproof cloth compression.Thickness 18-20cm is filled out in exposing the cultivation bed on earth's surface
Fermentation Flammulina velutiper (Fr.) Sing slag is aerial parts substrate, and Flammulina velutiper (Fr.) Sing slag and slag are 1:1.5 by weight proportion, and laying is dripped on substrate
Fill band 1-2 bar.Carry out disinfection sterilization with substrate in warmhouse booth afterwards;The sterilization of disease pest in the 6-7 month carries out greenhouse, often
Year is once.Fructus Lycopersici esculenti seedling selects high yield, disease-resistant, fruit type uniform one dimensional infinite wall Fructus Lycopersici esculenti breeding, carries out planting without soil before transplanting
Cultivate Seedling.
