Problems solved by technology

[0004] The purpose of the present invention is to solve the above-mentioned defects in the prior art, aiming at the shortcomings of current solanaceous vegetable grafting rootstocks and scion seedlings that have a long seedling period, need to fix the grafting interface, and difficult to maintain humidity, etc., to develop a short seedling stage The young seedlings (rootstock seedlings and scion seedlings) are a new method of raising seedlings by grafting with simple and quick top cutting method

Embodiment 1

[0022] Cut off the rootstock seedlings at the internode of the second section above the cotyledons, drill a socket with an inclination angle of 45° downwards from the rootstock incision with homemade sharp-billed bamboo slices, and control the depth of the socket at 5mm-10mm (the lower end can slightly penetrate the rootstock epidermis), pull up the whole scion seedling, cut it into a scion with 1-2 true leaves with a blade, cut the scion fracture horizontally and vertically with a blade to make it cut into wedge-shaped cuttings, and then Pull out the bamboo slice inserted in the socket of the rootstock, insert the scion in the socket of the stock, make the incision stem base of the scion fully contact the cambium of the socket of the rootstock, the purpose of full contact on the one hand makes the insertion of the scion stable, and does not need other fixing devices; On the one hand, it improves the survival rate of grafting.

[0025] Cut off the rootstock seedlings at the internode of the third section above the cotyledon, drill a socket with an inclination angle of 30° downwards from the rootstock incision with homemade sharp-billed bamboo slices, and control the depth of the socket at 5mm-10mm (the lower end can slightly penetrate the rootstock epidermis), pull up the whole scion seedling, cut it into a scion with 1-2 true leaves with a blade, cut the scion fracture horizontally and vertically with a blade, cut into wedge-shaped cuttings, and then pull out Insert the tip of the bamboo piece into the socket of the rootstock, insert the scion into the socket of the rootstock, and make the base of the cut stem of the scion fully contact the cambium of the socket of the rootstock. The purpose of full contact is to make the insertion of the scion stable on the one hand, without other fixing devices; Improve the survival rate of grafting.

Abstract

The invention provides a method for raising solanaceous vegetable seedlings by grafting. The method comprises the steps of cutting off certain internodes, below the fifth nodes and above cotyledons, of stock seedlings; drilling an inserting port downwards in a stock cut, wherein the depth of the inserting port is 5mm-10mm, and the inclination of the inserting port is 30 degrees to 60 degrees; inserting a scion with one or two true leaves into the inserting port, and enabling the basal part of the stem of the scion to make full contact with a cambium of the inserting port of the stock; mulching the surface of a plant with a film to carry out sealing and moisture retention after grafting, and maintaining the air humidity to be above 95% inside the film for seven to ten days to promote the inserting port of the stock and the scion to coalesce and survive; opening the film to ventilate and harden seedlings gradually after the inserting port coalesced. According to the method for raising the solanaceous vegetable seedlings by the grafting, small seedlings (stock seedlings and scion seedlings) of short seedling stages are utilized, and the grafting is carried out by adopting a top grafting method which is simple and fast in operation. Through the adoption of the method, seedling cultivating time can be shortened, and seedling cultivating cost can be reduced.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for grafting and growing seedlings of solanaceous vegetables. Background technique [0002] The use of grafting cultivation in the production of tomato, eggplant, pepper (sweet pepper) and other solanaceous vegetables is to prevent and control soil-borne diseases such as bacterial wilt, Verticillium wilt, blight, and root-knot nematode, and to improve the heat resistance, cold resistance, and tolerance of scion varieties. Most effective for stress resistance such as barrenness, pickling, etc. Developed countries in the vegetable industry have generally promoted the application of grafting cultivation, and the promotion area of ​​grafting cultivation of solanaceous vegetables in my country is also increasing. [0003] The traditional grafting of solanaceous vegetables mainly adopts methods such as split grafting and pasting grafting. The disadvantage of these methods is that t...
