Novel method for eggplant grafting and seedling raising through cuttage grafting

Abstract

The invention relates to the field of agricultural seedling cultivation, in particular to a novel method for eggplant grafting and seedling raising through cuttage grafting. Seedlings of eggplant rootstocks with four leaves and seedlings of eggplant scions with two leaves are selected; the eggplant rootstocks are flatly cut at the positions 4 centimeters away from the ground, and the heads of theeggplant rootstocks are removed; the roots of the eggplant scions are obliquely cut off by using a blade in a manner that an angle of 45 degrees is formed between the blade and the stems of the eggplant scions at the positions 1-2 cm away from core leaves; grafting prods with an angle of 45 degrees are obliquely inserted into the opposite sides of the stems of the eggplant scions from top to bottom at the positions 0.3-0.5 cm away from the tops of the eggplant rootstocks; the grafting prods are pulled out, and the eggplant scions are inserted into grafting holes; and after grafting is completed, the seedlings are placed below the a thin film for moisturizing and shading, and other post-grafting technical management is the same as that of a cleft grafting method and an inarching method. According to the novel method provided by the invention, few tools are used, labor is saved, and is operation is easy.

Description

technical field [0001] The invention relates to the field of agricultural seedling cultivation, in particular to a new method for grafting and cultivating eggplant seedlings by grafting. Background technique [0002] Eggplant is one of the most widely cultivated vegetables in the north and south of my country, especially in the vast rural areas, where the cultivation area of ​​eggplant is far larger than that of tomato. Eggplant has strong adaptability, high yield and long supply period, and is the main fruit and vegetable in summer and autumn. It is cultivated in spring and autumn in the Yangtze River Basin, and the market period can last from May to October. Eggplant is fed with tender fruit. Although its vitamin C content is not high, only 2 to 3 mg per 100 grams of fresh weight, it contains more dry matter (6% to 7%) necessary for the human body, such as carbohydrates and proteins. And calcium, iron etc. Eggplant can be eaten in a variety of ways, such as roasting, fr...

Problems solved by technology

[0005] With the continuous improvement and improvement of various technologies for eggplant annual production, the area has expanded year by year, and the amount of seedlings has also increased year by year, because the original two grafting methods are often slow in grafting due to cumbersome techniques, which affects the production of seedlings and high production costs.
