High output and good quality aubergine graft and transplantation technique in different seasons

Abstract

The invention relates to a technology for grafting and transplanting of a high-yield and high-quality anti-seasonal eggplant, which comprises the following steps: (1) a common eggplant is taken as a graft and Solanum torvum is taken as a rootstock; (2) the seeds of the Solanum torvum are used for raising seedlings in July, and the seeds of the eggplant are used for raising seedlings in August; when the seedlings of the Solanum torvum grow 7-9 true leaves and the seedlings of the eggplant grow 4-5 true leaves, the seedlings are taken out; (3) a growing point which is 60-80mm from the root of Solanum torvum is cut off, and the end of the rootstock is cut into a wedge shape; the eggplant seedling is cut into a bevel opening at the eggplant seedling 60-80mm above a cotyledon from bottom to top, and the wedge-shaped end of the rootstock is inserted into the bevel opening of the graft with cortex aligned, and then the graft opening is bound up and fixed to form a two-root seedling; (4) the two-root seedling is transplanted into a field while grafting; after 10-15 days upon transplanting, when the wounds of the rootstock and the graft heal, the graft root is cut from the bottom of the graft opening with only the root of the rootstock left. The technology can cause the anti-seasonal eggplants planted in autumn and winter to have more strong vitality and the ability against diseases and insect pests; in addition, the eggplant planted by the technology has high yield and high quality, the seedling raising method is simple, the grafting seedling rate is high, thus the technology can realize transplanting seedlings into the field while grafting, which reduces the land, labor labor and production cost required by seed bed management.

Description

technical field [0001] The invention relates to an eggplant cultivation technique, in particular to a high-yield and high-quality off-season eggplant grafting and transplanting technique. Background technique [0002] Eggplant (Solanum melongans Linn) is an annual herbaceous plant with oval leaves, purple flowers, long strips or round fruits, white, green, and mostly purple in color, with a shiny surface. It is a popular vegetable. As a common vegetable, the cultivation of eggplant is a mature prior art. Ordinary home-grown eggplant has a strong seasonality, usually sown in March and bearing fruit in May. Ordinary eggplant has poor stress resistance, strong selectivity to soil, and does not grow well in poor soil. Ordinary eggplant has low ability to resist diseases and insect pests, and is prone to root rot, rotten feet and other diseases. Due to continuous planting all year round, soil-borne diseases, root-knot nematodes, eggplant Verticillium dahliae and other adverse ...

Problems solved by technology

The technique disclosed in "a kind of eggplant cultivation method" (CN01108575.4) that the inventor applied for in 2001 is to use water eggplant (Soianum torvum Sw.) as rootstock, and adopt the method of split grafting to graft eggplant. Eggplant can effectively improve the eggplant's ability to resist diseases and insect pests, and improve the quality and yield of eggplant, but this method needs to be cultivated in a seedling shed after the eggplant seedlings are grafted, and then transplanted to the field after the wound is healed. This method of seedling cultivation is complicated , higher seedling cost
