Abstract

The invention relates to a new method for grafting mango in a high-temperature and high-humidity season. The method comprises the following steps of lopping, grafting, binding, covering leaves, preventing pests and the like. From June to October, mango trees are grafted and the survival rate of the grafting reaches over 90 percent, which is increased by over 30 percent compared with that of the conventional grafting method in the same period; the problem of low survival rate of the grafting in the high-temperature high-humidity season is solved; the growth of the mango survived after the grafting is promoted; the economic benefit of a mango planter is improved; and the mature mango leaves can be used as rain-proof and sunscreen materials to shield rain and direct sunlight.

Description

A kind of high-temperature high humidity season mango grafting new method

Technical field

The invention belongs to the crop genetics field, specifically is a kind of high-temperature high humidity season mango grafting new method.

Background technology

Grafting is a kind of conventional method of doing sth. in advance the result on the production of fruit trees, keeping the kind good characteristic.The mango grafting time is typically chosen in 2-4 month, because spring temperature bottom out, resin begins to flow, and rainfall is few, and grafting survives easily, but in actual production, behind the fruit of having gathered, want to improve other kind, wait until grafting again in the beginning of spring, can make mango empty long half a year, cause the fruit problems such as evening of going into operation in the coming year; Conventional graft survival rate is extremely low.

Summary of the invention

The invention provides a kind of high-temperature high humidity season mango grafting new method, adopt the present invention can effectively solve an above-mentioned difficult problem, and because grafting time is at high-temperature high humidity season, can effectively improve the graft survival rate of mango, make the scion rain and sun simultaneously, impel mango to grow fast, going into operation ahead of time for mango lays the foundation.

The present invention mainly realizes by following technical step:

1, lopping: decide according to the grafting needs, the flat and bark not in stock cross section, and be deep to the stock xylem with cutter incision two cuttves and form the stock otch of growing 3～5cm, conform to grafting immediately after the lopping with scion.

2, grafting: the long 5～10cm of scion, with the sliding from top to bottom long otch close of cutting of one side, be deep to and cut a little xylem and be advisable with the stock otch, end is cut angle at 45 at the otch back side.

3, binding: the long bevel of scion is inwardly inserted in the stock otch that cuts, and after the driving fit of anvil fringe, with wide 2.5～30cm, the film tape of thick 0.01～0.02mm with interface section elder generation tighten, carries out totally-enclosed wrapping with scion from bottom to top again, does not reveal eye.

4, Gai Ye: become semicircle with fresh ripe mango Lao Ye reverse side circle, the scion of mango grafting on stock covered, and with plastic film fastening reserving thrown at blade two and get final product.

5, pre-insect-pest: spray trunk with 2000 times of liquid of 2.5% decis after the grafting and reach the grafting mouth on every side.

The present invention adopts steps such as lopping, grafting, binding, lid leaf and pre-insect-pest, reach more than 90% at 6-10 month grafting mango graft survival rate, than the same period grafting method improve survival rate more than 30%, improved the low problem of high-temperature high humidity season graft survival rate, promote the growth of mango behind the grafting survival, increased mango grower economic benefit; Adopt ripe mango blade to prevent to drench with rain and sunlight directly shines as the rain and sun material.

Embodiment

Lopping: decide according to the grafting needs, the flat and bark not in cross section, and be deep to xylem with cutter incision two cuttves, long 3-5cm conforms to scion, grafting immediately after the lopping.

Grafting: scion wants 5-10cm long, and the sliding from top to bottom a kerf of cutting of one side is long close with the stock otch, is deep to cut a little xylem and be advisable, and end is cut angle at 45 at the otch back side.

3, binding: the long bevel of scion is inwardly inserted in the stock otch that cuts, after the driving fit of anvil fringe, use wide 2.5-3cm, the film tape of thick 0.01-0.02mm with interface section elder generation tighten, carries out totally-enclosed wrapping with scion from bottom to top again, does not reveal eye.

4, Gai Ye: become semicircle with fresh ripe mango Lao Ye reverse side circle, the scion of mango grafting on stock covered, and blade two fastening reserving of Peng got final product with plastic film.

5, pre-insect-pest: be sprayed on 2000 times of liquid of 2.5% decis after the grafting and reach the grafting mouth around the trunk and get final product.

6, bud is stayed in bud picking: outside the bud that keep 1 robust growth in the dried different azimuth of each section, grows fine, should erase unnecessary intensive bud, weak bud.

Use the present invention, can effectively improve the mango graft survival rate in 6-10 month grafting, the mango graft survival rate reaches more than 90%, improves more than 30% than conventional grafting method, improve the low problem of high-temperature high humidity season graft survival rate, promoted the growth of mango behind the grafting survival.

Claims

1. high-temperature high humidity season mango grafting new method is characterized in that step is as follows:
