Embodiment Construction

[0012] 1. Grafting object and time: mango saplings or seedlings, trunk diameter: 0.5-5.0cm range, grafting time is 6-10 months.

[0013] Pruning: according to the needs of grafting, the cross-section is flat without cracking the skin, and two cuts are made with a knife deep to the xylem, 3-5cm long, consistent with the scion, grafted immediately after pruning.

[0014] 2. Grafting: The scion should be 4-6cm long, cut a cut from top to bottom on one side, the length is similar to the cut of the rootstock, and it is advisable to cut a little xylem as deep as possible, and make a 45° oblique cut at the end of the back of the cut.

[0015] 3. Binding: Insert the long cut side of the scion into the incision of the cut rootstock. After the rootstock is sealed, use a film strip with a width of 2.5-3cm and a thickness of 0.01-0.02mm to tighten the interface part from bottom to top. Then the scion is completely closed and bandaged, so that the bud eyes are not exposed. The length of t...

Abstract

Disclosed is a novel method for rainproof grafting of mango saplings or seedlings. The grafting can be conducted in the period from June to October, when rainy days, high temperature and high humidity exist, the grafting surviving rate is more than 84.8%, and mangos can grow quickly due to the fact that the grafting period is a high-temperature and high-humidity season. The method comprises that branches of which upper portions are aging and eyes are full serve as scions and are in the surrounding of a tree crown, the scion lengths are in a range from 4cm to 6cm, long cutting surfaces of scions are inserted into cut stock incisions inwards, incision parts are tied from bottom to top by a thin film strip after stock-scions are sealed, scions are wrapped in a complete-sealing mode, eyes are not exposed, mango mature fresh old leaves of which lengths are in a range from 12cm to 20cm are reversely circled to form a semi-circle, scions grafted on stocks are covered, two ends of leaves are tied and fixed by tape, and after the grafting, an organic silicon pesticide synergist agent of 0.1% of 2000 times liquid of deltamethrin of 2.5% of volume concentration is used for spraying the surrounding of a tree and grafting positions.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a new rain-proof grafting method for mango saplings or seedlings. Background technique [0002] Grafting is a conventional method for early fruiting and maintaining the good characteristics of varieties in fruit tree production. The time for mango grafting is usually February-April and June-October. Due to the high temperature, high humidity, and heavy rainfall in June-October, the survival rate of conventional grafting is extremely low. At present, grafting in June-October is generally avoided. Therefore, the propagation speed of mango seedlings is greatly limited, and the propagation of mango seedlings and the economic income of growers are affected. Contents of the invention [0003] The invention provides a new rain-proof grafting method for mango saplings or seedlings. The above problems can be effectively solved by adopting the invention. Grafting is carried out during Ju...
