Continuous cropping type eggplant grafting method

Abstract

Disclosed is a continuous cropping type eggplantgrafting method. The method comprises the steps of (1) stock selection, wherein the stock is solanum torvum and the scion is an ordinary eggplant variety; (2) culturing, wherein a solanum torvum stock seedling and a scion seedling are cultured independently, and grafting is conducted after the scion seedling grows 3-4 blades; (3) grafting, wherein cleft grafting is carried out on the scion seedling at the position 5-8cm above the soil surface of the solanum torvum stock seedling, dryness needs to be guaranteed during cleft grafting, and water feeding must be absolutely prohibited; (4) seedling culturing, wherein the well grafted eggplant seedling is well covered by a film to be cultured at a temperature of 25-28 DEG C and an air humidity of 70-95% for 60days; (5) transplanting, wherein the eggplant seedling is transplanted to a cold shed for 120days, and then grafting is achieved successfully. The method breaks through the habitual mindset that eggplants can not be cropped continuously. According to the method, the eggplants can be cropped continuously on the same field within 4-5 years, the yield is high and can reach 2-3 times of the yield obtained with the traditional planting method, and the color and taste of the eggplants are improved greatly.
