Problems solved by technology

[0002] Eggplant is the main variety of vegetable production in protected areas. Due to continuous cropping cultivation for many years, the occurrence of various soil-borne diseases, especially root-knot nematode, has been increasing year by year. Root-knot nematode has become a devastating disease of vegetable protected cultivation. , often resulting in severe production cuts or even crop failures

Embodiment 1

[0022] Example 1: A eggplant cultivar Nongyou Changqie, which is highly susceptible to root-knot nematode, is used as a scion, and Datura is used as a rootstock to cultivate root-knot-resistant eggplant for oversummer and autumn stubble cultivation.

[0023] 1. The cultivation steps of root-knot-resistant eggplant are as follows:

[0024] 1) On February 1, 2007, Datura (Datura Stramonium L.) seeds were sown in the substrate, and then watered so that the moisture content of the substrate was 60% to 80%, and placed in a seedling room at 20 to 28°C Make it emerge, and cultivate the rootstock until there are 5 to 7 true leaves and strong seedlings.

[0025] 2) On February 6th, 2007, sow the nongyou long eggplant seeds into the matrix, then water it so that the water content of the matrix is ​​60% to 80%, and put it in a seedling room at 20 to 28°C to make it emerge. The scion plants are cultivated until there are 4-6 true leaves and strong seedlings.

[0026] The matrix is ​​com...

Embodiment 2

[0051] Example 2: The root-knot-resistant eggplant was cultivated with a conventionally cultivated eggplant variety Bulita highly susceptible to root-knot nematode as the scion and Datura as the rootstock, and then cultivated in winter and spring.

[0052] The following experiments were carried out in a green food and vegetable base:

[0053] 1. The cultivation steps of root-knot-resistant eggplant are as follows:

[0054] 1) On October 15th, 2007, Datura (Datura Stramonium L.) seeds were sown in the matrix, then watered so that the moisture content of the matrix was 60% to 80%, and placed in a seedling room at 20 to 28°C Make it emerge, and cultivate the rootstock until there are 5 to 7 true leaves and strong seedlings.

[0055] 2) On October 20, 2007, sow the burita seeds in the matrix, then water it so that the water content of the matrix is ​​60% to 80%, put it in a seedling room at 20 to 28°C to make it emerge, and put the scion Plants are cultivated until some 4-6 true...

Abstract

The invention relates to a method for cultivating a root-knot nematode-resistant eggplant plant. The method is to graft a plant of a conventionally cultivated highly root-knot nematode-sensitive eggplant variety serving as a scion onto a stramonium plant serving as a stock to obtain a graft plant, that is, the root-knot nematode-resistant eggplant plant. The root-knot nematode-resistant stramonium plant is adopted as the stock, the plant of the conventionally cultivated highly root-knot nematode-sensitive eggplant variety is adopted as the scion and the seedlings are grafted at the most proper position by the most proper method in a period of highest affinity, so the method can improve the inosculation of the two, greatly improve the survival rate of grafting by improving cultivation conditions. The grafted seedling has obvious prevention and cure effect on root-knot nematode and overcomes a continuous cropping obstacle, so the method enormously improves economic efficiency and, meanwhile, achieves obvious ecological benefits due to reduction in use of agricultural chemicals.

Description

technical field [0001] The invention relates to a method for cultivating eggplants resistant to root-knot nematodes in the field of biotechnology, which is used for root-knot nematode-resistant cultivation of eggplants. Background technique [0002] Eggplant is the main variety of vegetable production in protected areas. Due to continuous cropping cultivation for many years, the occurrence of various soil-borne diseases, especially root-knot nematode, has been increasing year by year. Root-knot nematode has become a devastating disease of vegetable protected cultivation. , often resulting in severe production cuts or even crop failures. [0003] Eggplant grafting can not only prevent disease, but also because the rootstock has a more developed root system than the original scion, and has a stronger ability to absorb water and fertilizer, it can significantly increase the yield. Use rootstocks that are highly resistant to various soil-borne diseases and good-yield eggplant va...
