Description

A kind of method for cultivating color green pepper health grafting
Technical field
The present invention relates to a kind of breeding method of color green pepper seedling, specifically, is related to a kind of cultivation color green pepper health grafting Method, belong to vegetables seedling-raising technique field.
Background technology
Color green pepper hole tray graft seedling growth is widely used to produce.Hole plate seedling growth is educated with light materials such as turf, vermiculites Seedling matrix, using precision drilling, the modernization nursery system of once-seedling forming.Traditional hole plate seedling growth technology have energy-conservation, saving of labor, Laborsaving, saving seedbed area, economizes on kind, is easy to long distance transportation to also allow for using the advantages that standardizing seedling management technology, Field planting easily survives, no seedling-slowing stage, and nursery production realizes specialized, mechanization, and commercialization is realized for seedling.
In process of the present invention is realized, inventor has found following defect in the prior art at least be present：Traditional color green pepper cave Disk graft seedling growth technology is caused under grafting quality because the factors such as hole plate seedling growth environment tend to cause grafting excessive growth Drop, it is mainly shown as that the rooting ability after grafting field planting is poor, growth potential is weak, and malformed fruit rate is high（Mainly seedling stage bud differentiation Caused by bad）, disease resistance is poor.
The content of the invention
The technical problems to be solved by the invention are to be directed to problem above, there is provided a kind of side for cultivating color green pepper health grafting It method, can effectively suppress grafting excessive growth, be advantageous to nurturing staff, promote root system development, improve root activity and seedling vigorous index；Promote Enter bud well to break up, reduce malformed fruit rate, improve the commodity of fruit；Strengthen the disease resistance of grafting, reduce chemical pesticide Access times and dosage；Improve color green pepper yield.
To solve the above problems, the present invention adopts the following technical scheme that：The method for cultivating color green pepper health grafting, by grass Charcoal, vermiculite, perlite 6: 2: 2 uniform mixed preparing seedling medium by volume, make stock from Wild pepper after medium in tray, Color green pepper hole tray graft seedling growth is carried out, is comprised the following steps：
1）Scion is sowed with the stock same period, and stock seed is sowed at 72 hole standard hole trays, and ingraftment seed is sowed at 105 hole standard caves Disk；
2）Every plant is poured that to apply concentration be 50mgkg when stock seed germination to cotyledon deploys-1Potassium phosphite aqueous solution 5- 8ml；
3）It is 7.5mgkg that the 1st lobus cardiacus dew point of scion, which pours to every plant during 11 heart of leaf and apply concentration,-1The Prohexadione calcium aqueous solution 8-10ml；
4）Grafting when stock, scion have 3-4 piece true leaves, stock remove whole true leaves and cotyledon, and scion retains the heart of 2 leaf 1 True leaf；
5）When the 3rd true leaf length reaches 1cm after grafting, every plant is poured that to apply concentration be 15mgkg-1Prohexadione calcium it is water-soluble Liquid 8-10ml；
6）When the 4th true leaf length reaches 1cm after grafting, every plant is poured that to apply concentration be 500mgkg-1Chitosan aqueous solution 12-15ml。
A kind of prioritization scheme, stock are cloth open country fourth, a kind of Wild pepper.
Another prioritization scheme, stock are that prestige strengthens Bel, a kind of Wild pepper.
Another prioritization scheme, stock and scion carry out grafting using cleft graft.
Another prioritization scheme, the appropriate full dissolubility all-element compound fertilizer of seedling medium addition, makes the initial nutrient of seedling medium N、P2O5、K2O content is respectively：50-60mg·kg-1、20-40mg·kg-1、80-90mg·kg-1, middle trace element is appropriate, EC Value 1.0-1.5mscm-1。
Further, grafting seedling vigorous index is 0.0319-0.0356, improves 22.2%-27.6%；
Grafting root activity is 84.7mgg-1·h-1-87.5mg·g-1·h- 1,, improve 17.3%-21.2%；
Malformed fruit rate is 0 after grafting field planting；
The field phytophthora root rot incidence of disease is 0 after grafting field planting；
Chemical pesticide can be reduced in production using 3-5 times, chemical pesticide usage amount reduces more than 40%；
Total output is 5247.8-13251.8kg/ mus after grafting field planting, increases production 20%-21.2%.
Standard hole tray is more cavities containers for vegetables nursery, is made of plastics, the size of standard hole tray is long 52cm × wide 28cm × high 4.5cm.
Using above technical scheme, compared with prior art, there is advantages below：
（1）Rice shoot excessive growth can effectively be suppressed, be advantageous to nurturing staff, promote root system development, root activity is improved and strengthen Seedling index.According to experiment, gained grafting seedling vigorous index is 0.0319-0.0356, more conventional to educate hole tray grafting raising 22.2%- 27.6%；Root activity is 84.7mgg-1·h-1-87.5mg·g-1·h- 1,, more conventional hole tray grafting raising 17.3%- 21.2%。
（2）Grafting bud differentiation is good, is advantageous to improve the commodity of fruit.According to experiment, gained grafting color green pepper fruit Real malformed fruit rate is 0, and conventional hole tray grafting color green pepper deformed fruit fruit rate is 11.9%-13.6%.
（3）Grafting disease resistance is strong, is advantageous to realize that the decrement of chemical pesticide uses in color green pepper cultivation.According to experiment, institute The field phytophthora root rot incidence of disease is 0 after obtaining grafting field planting, the disease such as virosis, bacterial leaf spot, gray mold, epidemic disease The incidence of disease is also far below conventional hole tray grafting, chemical pesticide can be reduced in production using 3-5 times, chemical pesticide usage amount is reduced More than 40%.
（4）Be advantageous to improve color green pepper yield.According to experiment, yield is 5247.8-13251.8kg/ after the field planting of gained grafting Mu, more conventional hole tray grafting improve 20%-21.2%.
Selection and the dosage of potassium phosphite, Prohexadione calcium and chitosan in the present invention, are the biological characteristics according to color green pepper Property, the effect of color green pepper physiology, plant growth regulator, and result of the test of the present inventor in color green pepper hole tray graft seedling growth And determine.Watering is the most frequent field operation of hole plate seedling growth, and potassium phosphite, Prohexadione calcium and chitosan pour that apply can be adjoint Watering is carried out, and does not increase recruitment.
The raw materials used present invention is to allow what is used in agricultural production, and raw materials market is on sale.
With reference to embodiment, the present invention is described in detail.
