Abstract

A big bud-big stock grafting method for watermelon includes sowing sotck (bottle gourd) 15-25 days earlier than that of watermelon, cutting a cross section on the stock when said stock has two euphylises and one spindle leaf and said scion has two cotyledons, inserting a bamboo strip in its top, cutting the scion to become a wedge, pulling out said bamboo strip, and inserting the scion.

Description

The big bud big stock grafting of watermelon method

Technical field

The present invention relates to a kind of grafting method, be specifically related to the big bud big stock grafting of a kind of watermelon method.

Technical background

The watermelon grafting cultivation is a disease-preventing and yield-increasing, simple and easy to do effective measures, utilizes the disease resistance of stock and powerful root system, and the continuous cropping ground watermelon blight incidence of disease is controlled in 10%.The watermelon grafting has grafting, is abutted against, cleft grafting, several different methods such as amplexiform, and wherein the method for plant propagation with cutting is because of easy and simple to handle, and survival rate is higher and be widely used.Peg graft but adopt cucurbit to do stock, mostly grafting when stock 2 cotyledons 1 heart in the past, at this moment cucurbit mostly is hollow, and the back watermelon of pegging graft easily takes root or causes the cucurbit stem to split in the cucurbit stem, and survival rate has only about 60%.

Summary of the invention

The objective of the invention is to overcome weak point in the prior art, a kind of easy and simple to handle, work efficiency is fast and graft survival rate is high method is provided.

The present invention is achieved by following technical proposals: before the watermelon graft seedling growth, stock (cucurbit or edible gourd) sowing is done sth. in advance 15～25 days than watermelon, watermelon is broadcast back 5～10 days, when stock reaches 2 true leaves, 1 heart, when scion 2 cotyledons have just launched, earlier the growing point that eliminates more than stock two cotyledons with blade forms a cross section, treats grafting again after the wound healing; Before the grafting with flat bamboo let (wide 0.2cm, thick 0.1cm grow 8～12cm), at the top of seedling stem along epidermis inboard, cross section hole of oblique cutting downwards, bamboo let wouldn't be extracted.After scion uses the clear water rinsing clean in advance, again with soaking in the 75% tpn 600-800 times+64% Sandofan 600-800 times mixed liquor, carry out disinfection, and be placed on the sterile wet cloth, be whittled into the lozenges of long 0.5-0.8cm during grafting with the past root direction in double-edged razor blade 1cm place under the cotyledon of scion, extract the bamboo let on the stock, stock is inserted in the scion that will cut immediately, the cotyledon direction of scion should be consistent with stock cotyledon direction, utilizes the scion of stock cotyledon support; After grafting is finished, further strengthen the field management of grafting, the survival rate of grafting can reach more than 95%.

Because adopt technique scheme, the big bud big stock grafting of watermelon provided by the invention method has such beneficial effect, promptly elongated the grafting optimum period, easy and simple to handle, work efficiency is fast, graft survival rate is high; Also help and save seed, and can reduce the generation of damage by disease and insect, promote watermelon listing ahead of time, obviously improved the economic benefit of watermelon.

Method of the present invention also is applicable to gourd vegetables such as seed water melon, muskmelon.

Embodiment

The invention will be further described below in conjunction with embodiment.

1, before the watermelon graft seedling growth, stock (cucurbit) sowing is done sth. in advance 20 days than watermelon, (promptly treating to broadcast when stock has 2 true leaves watermelon), watermelon after planting 6～8 days again, when stock reaches 2 true leaves, 1 heart, when just having launched, scion 2 cotyledons can carry out the preceding preparation of grafting.

2, the growing point that eliminates more than stock two cotyledons with blade earlier forms a cross section, and the cross section is waited 3-5 days apart from the about 0.2cm of cotyledon base portion, treats grafting again after the wound healing.

3, with flat bamboo let (wide 0.2cm, thick 0.1cm, long 10cm), at the top of rootstock seedling stem along epidermis inboard, cross section hole of oblique cutting downwards, the long 0.9cm of jack, bamboo let wouldn't be extracted.

4, after scion uses the clear water rinsing clean in advance, carry out disinfection with soaking in 700 times of mixed liquors of 75% tpn, 700 times+64% Sandofan again, be placed in the dish on the sterile wet cloth, the last lid layer cloth that wets is in case the dehydration wilting.

5, be whittled into the lozenges of length 0.7cm with double-edged razor blade 1cm place under the cotyledon of scion toward the root direction during grafting, extract the bamboo let on the stock, stock is inserted in the scion that will cut immediately.The cotyledon direction of scion should be consistent with stock cotyledon direction, utilizes the scion of stock cotyledon support.

6, after grafting is finished, further strengthen the field management of grafting, reach more than 95% with the survival rate of guaranteeing grafting.
