Problems solved by technology

[0002] In recent years, with the adjustment of the agricultural planting structure, the planting area of ​​vegetables has been continuously expanding. Due to continuous cropping for many years, root-knot nematode has become a devastating disease of vegetable protected cultivation. Except for peppers, onions, and garlic, no infection has been found so far. , almost all vegetables have been harmed, especially melons, eggplants, beans, etc. have suffered the most serious damage, often resulting in severe production reduction or even crop failure

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. Sow root-knot nematode-resistant tomato He-Man (L. lycopersicum x L. hirsutum) on July 25 to be used as 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. The weather was fine from August 30 to September 2, and grafting began on August 30. The seedlings are watered one day before grafting, the water con...

Abstract

A method for culturing the tomato resisting against rhizomynematoda features the grafting between the tomato He-Man (L.lycopersicum * L.hircutum) 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 continued to expand. Due to continuous cropping for many years, root-knot nematode has become a devastating disease of vegetable protected cultivation. Except for peppers, onions, and garlic, no infection has been found so far. , almost all vegetables have been harmed, especially melons, eggplants, beans, etc. have suffered the most serious harm, often resulting in severe production reduction or even crop failure. [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 serious. Tomato grafting can not only...
