[summary of the invention]
The invention provides the soilless culture method of tomato in a kind of greenhouse, combine the advantage of greenhouse culture and the advantage of soilless culture, significantly improved tomato planting output, mouthfeel, quality and safety.Technical scheme of the present invention is as follows:
In greenhouse, a soilless culture method for tomato, comprises the steps:
(1). by the land readjustment in green house, and compacting compression soil, then adopt the partly mode of burying to excavate cultivating groove, cultivating groove excavating depth under earth's surface is 20-30cm, wide 40-50cm, the length of cultivating groove is determined according to the concrete size in greenhouse; Between every adjacent 2 cultivating grooves, reserve the aisle of 50cm, spread waterproof cloth in cultivating groove, waterproof cloth is close to cell wall, spreads solid clay brick form the height that exposes earth's surface in the edge of cultivating groove;
(2). the sterilization that carries out disinfection in green house, after first fully mixing according to every mu of use dichlorvos 1kg and 5-10kg sawdust, spread surface, aisle, disinfecting time 12-24 hour; Again the dry straw of 4-5kg is layered on to ground, sawdust 5kg tiles above straw, places sulphur 1kg topmost, closes after green house door and ventilating opening, lights the stifling 12-24 hour of straw;
(3). to the sterilization that carries out disinfection of Asparagus slag and slag matrix, with film, respectively by matrix parcel, stack 7-10 days, during stacking, substrate temperature reaches 70 ℃, can kill most of fungal disease and Disease;
(4), on cultivating groove inner waterproofing cloth, fill up particle volume and be less than 1cm
3slag, then fill out the fermentation Asparagus slag of 18-20cm thickness, Asparagus slag and slag ratio are 1:1.5 by weight, and lay irrigate band 1-2 bar in stromal surface;
(5), tomato seeds soaks after 2 days water planting 20-25 days in husky base, the height of tomato seedling reaches 8cm and highly gets final product field planting;
(6) tomato seedling is pressed to spacing in the rows 60cm, the specification of line-spacing 30cm is planted in cultivating groove, every mu of 1800-2000 strain, and put up support, tomato adopts goes alone pruning technique, extract side shoot, flower and fruit thinning, is used the drip irrigation system being equipped with to implement liquid manure nutrition liquid irrigation, when Relative water content is less than 45% in good time, carry out liquid manure nutrition liquid irrigation 5-8 minute, Relative water content is greater than 80% to be stopped irrigating;
(7) tomato growth period management, take and prevent and treat epidemic disease, virus disease as main seedling stage, adopts low-toxin farm chemicals control; After a month tomato starts to bear fruit, focus on powdery mildew and pest control, adopt biopesticide to carry out worm control, tomato plant height grows to 80-120cm, puts climingly, and should increase in right amount nitrogen application seedling stage, and fruiting period should increase potash fertilizer usage amount.
More than described green house height 2.5m, green house ventilating opening and door are installed fly net; Green house surrounding antecedent soil moisture, has drain ditch.
Described slag is the slag that coal-burning boiler produces, and it is the fritter of diameter 0.7-1.3cm that slag is pulverized; Fermentation Asparagus slag is to spray water to mushroom slag surface wettability, at normal temperatures pile fermentation 25-30 days after needle mushroom ground-slag is broken, tiling.
Described waterproof cloth width 1-2m.
The solid clay brick of cultivating groove edge is of a size of 240 * 120 * 60mm, at the edge of cultivating groove layer overlay solid clay brick, waterproof cloth is stretched and to cover solid clay brick piece upper surface to surrounding, then add 2 layers of solid clay brick waterproof cloth is compressed.
The described dropper system of step (6) adopts 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:
Nutrient solution a: the pollution-free running water 5000kg of potassium sulfate (3~7kg)+ammonium nitrate (2~6kg)+potassium dihydrogen phosphate (0.5~1.5kg)+magnesium sulfate (2~8kg)+boric acid 15g+ manganese sulphate 10g+ ammonium molybdate 0.1g+ zinc sulphate 1g+ copper sulphate 0.4g+ iron sulfate 500g+EDTA700g+;
Nutrient solution b: the pollution-free running water 5000kg of nitrate of lime (8~20kg)+potassium nitrate (3~10kg)+boric acid 15g+ manganese sulphate 10g+ ammonium molybdate 0.1g+ zinc sulphate 1g+ copper sulphate 0.4g+ iron sulfate 500g+EDTA700g+;
Nutrient solution a and nutrient solution b are used alternatingly, and suitably heighten the ratio of ammonium nitrate seedling stage, and fruiting period is suitably heightened the ratio of potassium sulfate and potassium nitrate.
Cultivating groove of the present invention adopts the mode of partly burying, the input that can save in a large number material.The matrix of using is divided into 2 layers, all uses slags below earth's surface, and acrial part matrix is Asparagus slag, and this matrix has larger porosity, is conducive to moisture and the nutrient of breathing, expansion and the absorption bottom of root system.Matrix sterilization of the present invention adopts 70 ℃ of above high temperature sterilizations, and mainly killing object is masaic of tomato.Adopt method of the present invention cultivation tomato, reduced agriculture chemical usage amount and labour and dropped into, tomato yield, carbohydrate content and Vc content have had and have increased substantially, and this invention is practical, has good economic worth.
[embodiment]
Various embodiments of the present invention comprise the steps:
The design of cultivating groove: more than green house height 2.5m, green house ventilating opening and door are installed fly net; Green house surrounding antecedent soil moisture, has drain ditch.First in green house by land readjustment, and compacting compresses soil.Excavation cultivating groove, cultivating groove adopts the mode of partly burying, and under earth's surface, excavating depth is 20-30cm, the groove of wide 40-50cm, the length of groove is determined according to the concrete size in greenhouse; Between every adjacent 2 cultivating grooves, reserve the aisle of 50cm.In cultivating groove, spread waterproof cloth, waterproof cloth width 1-2m, waterproof cloth is close to cell wall, fills up particle volume and be less than 1cm in waterproof cloth
3slag.At the edge of cultivating groove layer overlay solid clay brick, increase the height of groove, solid clay brick size: 240 * 120 * 60mm, stretches waterproof cloth to cover fragment of brick upper surface to surrounding, and adds 2 layers of solid clay brick again waterproof cloth is compressed.Expose that in the cultivating groove on earth's surface, to fill out thickness 18-20cm fermentation Asparagus slag be acrial part matrix, Asparagus slag and slag are 1:1.5 by weight proportion, and on matrix, lay irrigate band 1-2 bar.Afterwards in green house and the matrix sterilization that carries out disinfection; In the 6-7 month, carry out the sterilization of sick worm in greenhouse, once a year.Tomato seedling is selected high yield, disease-resistant, the even indeterminate growth type of fruit type tomato breeding, carries out soilless culture and grow seedlings before transplanting.
