Abstract

The invention discloses a kind of Citrullus vulgaris big bud big stock grafting method, it is desirable to provide a kind of easy and simple to handle, work efficiency is fast and graft survival rate is high method.Its technical scheme is characterized by, and stock (calabash or Pericarpium Lagenariae hispidae) sowing does sth. in advance 15～25 days than Citrullus vulgaris, when stock reaches 2 true leaf 1 hearts, when scion 2 cotyledon just launches, first on stock, it is whittled into a cross section with blade, then with flat bamboo let in one hole of its top oblique cutting, bamboo let wouldn't be extracted；Locating under the cotyledon of scion with blade during grafting, be whittled into a lozenges, extract the bamboo let on stock, the scion cut is inserted stock, the cotyledon direction of scion should be consistent with stock cotyledon direction, utilizes stock cotyledon support scion, completes grafting.The present invention is conducive to saving watermelon seed and reducing the generation of pest and disease damage, promotes Citrullus vulgaris listing ahead of time.

Description

A kind of Citrullus vulgaris big bud big stock grafting method

Technical field

The present invention relates to a kind of engrafting method, be specifically related to a kind of Citrullus vulgaris big bud big stock grafting method.

Background technology

Grafting watermelon 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 continuous cropping ground watermelon blight sickness rate can be made to control within 10%.Grafting watermelon has grafting, is abutted against, cleft grafting, the multiple method such as amplexiforms, and wherein the method for plant propagation with cutting is because of easy and simple to handle, and survival rate is higher and is widely used.But using calabash to do stock grafting, the most mostly grafting when stock 2 cotyledon 1 heart, at this moment calabash mostly is hollow, and after grafting, Citrullus vulgaris is easily taken root in calabash stem or causes calabash stem to split, and survival rate only has about 60%.

Summary of the invention

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

The technical scheme is that:

A kind of Citrullus vulgaris big bud big stock grafting method, it is characterized in that, it comprises the following steps: that (1) is before Grafting watermelon nursery, stock calabash or Pericarpium Lagenariae hispidae sowing do sth. in advance 15～25 days than Citrullus vulgaris, Citrullus vulgaris broadcasts latter 5～10 days, when stock reaches 2 true leaf 1 hearts, the preparation before grafting when scion 2 cotyledon just launches, can be carried out；(2) first eliminate one cross section of growing point formation of more than stock two cotyledon with blade, cross section, away from cotyledon base portion 0.2cm, waits 3～5 days, grafting again after wound healing；(3) with wide 0.2cm, thick 0.1cm, the flat bamboo let of long 8～12cm, at the top of rootstock seedling stem along one hole of oblique cutting downwards inside the epidermis of cross section, jack length 0.8～1cm, bamboo let wouldn't be extracted；(4) after scion uses clear water rinsed clean in advance, carrying out disinfection with soaking in 75% Bravo 600-800 times of mixed liquor of 600-800 times+64% Sandofan, on wet cloth sterilized in being placed on dish, one layer of wet cloth of upper cover, in case dehydration is wilted；(5) under the cotyledon of scion, at 1cm, it is whittled into the lozenges of length 0.5-0.8cm during grafting with double-edged razor blade toward root direction, extracts the bamboo let on stock, immediately stock is inserted in the scion cut；The cotyledon direction of scion should be consistent with stock cotyledon direction, utilizes stock cotyledon support scion, completes whole grafting procedures.

Owing to using technique scheme, the Citrullus vulgaris big bud big stock grafting method that the present invention provides, there is such beneficial effect, i.e. elongated grafting optimum period, easy and simple to handle, work efficiency is fast, graft survival rate is high；Also help and save seed and the generation of pest and disease damage can be reduced, promote Citrullus vulgaris listing ahead of time, hence it is evident that improve the economic benefit of Citrullus vulgaris.

The method of the present invention applies also for the melon vegetables such as seed water melon, Fructus Melo.

Detailed description of the invention

Below in conjunction with embodiment, the invention will be further described.

1, before Grafting watermelon nursery, stock (calabash) sowing does sth. in advance 20 days than Citrullus vulgaris, (i.e. broadcasting Citrullus vulgaris when stock has 2 true leaves again), Citrullus vulgaris after planting 6～8 days, when stock reaches 2 true leaf 1 hearts, the preparation before grafting when scion 2 cotyledon just launches, can be carried out.

2, first eliminate one cross section of growing point formation of more than stock two cotyledon with blade, cross section, away from cotyledon base portion 0.2cm, waits 3-5 days, grafting again after wound healing.

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

4, after scion uses clear water rinsed clean in advance, carrying out disinfection with soaking in 75% Bravo, 700 times of mixed liquors of 700 times of+64% Sandofan, on wet cloth sterilized in being placed on dish, one layer of wet cloth of upper cover, in case dehydration is wilted.

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

6, after grafting completes, the field management of grafting to be strengthened further, to guarantee that the survival rate of grafting is to more than 95%.

Claims

1. a Citrullus vulgaris big bud big stock grafting method, it is characterized in that, it comprises the following steps: that (1) is before Grafting watermelon nursery, stock calabash or Pericarpium Lagenariae hispidae sowing do sth. in advance 15～25 days than Citrullus vulgaris, Citrullus vulgaris broadcasts latter 5～10 days, when stock reaches 2 true time 1 hearts, the preparation before grafting when scion 2 cotyledon just launches, can be carried out；(2) first eliminate one cross section of growing point formation of more than stock two cotyledon with blade, cross section, away from cotyledon base portion 0.2cm, waits 3～5 days, grafting again after wound healing；(3) with wide 0.2cm, thick 0.1cm, the flat bamboo let of long 8～12cm, at the top of rootstock seedling stem along one hole of oblique cutting downwards inside the epidermis of cross section, insert Hole length 0.8～1cm, bamboo let wouldn't be extracted；(4) after scion uses clear water rinsed clean in advance, carry out disinfection with 75% Bravo 600-800 times of mixed liquor of 600-800 times+64% Sandofan soaks, on wet cloth sterilized in being placed on dish, upper cover one layer Wet cloth, in case dehydration is wilted；(5) under the cotyledon of scion, at 1cm, it is whittled into the lozenges of length 0.5-0.8cm during grafting with double-edged razor blade toward root direction, extracts the bamboo let on stock, immediately stock is inserted in the scion cut；The cotyledon direction of scion should be consistent with stock cotyledon direction, utilizes stock cotyledon support scion, completes whole grafting procedures.
