Embodiment 1

[0018] Embodiment 1, cultivating anti-root-knot nematode tomato

[0019] 1. Cultivation of root-knot nematode-resistant tomato grafted seedlings

[0020] The following experiments were conducted in Shouguang City, Shandong Province:

[0021] (1) Tomato Energy (L. esuclentum x L. esculentum) resistant to root-knot nematode disease was sown on July 25 to be used as a rootstock. Tomato FA-189, which is highly susceptible to root-knot nematode, was sown on July 28 for scion use. After sowing in the substrate (the substrate is composed of grass carbon, vermiculite and perlite, and the volume ratio of grass carbon, vermiculite and perlite is 3:2:1), water it so that the water content of the substrate is 60-80%, and put it in Emerge in a seedling room at 20-28°C, cultivate to strong seedlings with 4-5 true leaves, and prepare for grafting.

[0022] (2) From August 30th to September 2nd, the weather will be fine. Grafting began on August 30. The seedlings are watered one day befo...

Abstract

A method for culturing the tomato resisting against rhizomynematoda features the grafting between the tomato Energy (Lesuclentum * Lesculentum) as stock with high resistance to rhizomynematoda and the tomato FA-189 as scion with high sensitivity to rhizomynematoda.

Description

technical field [0001] The invention relates to a method for cultivating root-knot nematode-resistant tomatoes in the field of biotechnology. Background technique [0002] In recent years, with the adjustment of the agricultural planting structure, the planting area of ​​vegetables has been continuously expanded, and the incidence of root-knot nematode has been increasing year by year. Due to continuous cropping for many years, root-knot nematode has become a devastating disease of vegetable protected cultivation. Peppers, onions, and garlic have not been found to be infested so far, and almost all vegetables have been affected, especially melons, eggplants, and beans. Often result in severe production cuts or even no harvest. [0003] Tomato is the main variety of vegetable production in protected areas. Due to years of continuous crop cultivation, various diseases such as fusarium wilt, bacterial wilt, root-knot nematode, and viral diseases have become more and more serio...
