Method for cultivating root-knot nematode resistant eggplant

Abstract

The invention relates to a method for cultivating a root-knot nematode-resistant eggplant plant. The method comprises grafting a Bulita eggplant plant as a scion onto a super Solanum torvum plant as a stock. A graft plant obtained the grafting of the Bulita eggplant plant and the Solanum torvum plant has obvious prevention and cure effect on root-knot nematode in field. The method reduces use of agricultural chemicals, and consequently pollution to soil and environment, thereby achieving obvious economic and ecological benefits.

Description

technical field [0001] The invention relates to a method for cultivating plants, in particular to a method for cultivating eggplants resistant to root-knot nematode disease. Background technique [0002] In recent years, with the adjustment of the agricultural planting structure, the planting area of ​​eggplant in protected areas has been continuously expanding. Due to continuous cropping for many years, the incidence of root-knot nematode has been increasing year by year. It has become a devastating disease of eggplant cultivated in protected areas, often causing severe Reduced production or even no harvest has seriously restricted the production of vegetables in protected areas in my country.

[0002] In recent years, with the adjustment of the agricultural planting structure, the planting area of ​​eggplant in protected areas has been continuously expanding. Due to continuous cropping for many years, the incidence of root-knot nematode has been increasing year by year. It has become a devastating disease of eggplant cultivated in protected areas, often causing severe Reduced production or even no harvest has seriously restricted the production of vegetables in protected areas in my country

[0003] At present, the prevention and control methods of root-knot nematode at home and abroad mainly focus on the use of chemical pesticides to prevent diseases. Generally, chemical agents are used to fumigate the soil to kill nematodes. It has outstanding effects and has been widely used. However, methyl bromide is also a highly toxic gaseous pesticide. Improper use can cause human and animal injuries and soil pollution. At the same time, it has a huge destructive effect on the ozone layer, endangering human health and the earth's surface ecosystem; In addition, there are also crop rotation methods of planting non-host crops, but crop rotation can only reduce the occurrence of root-knot nematodes, and cannot achieve a radical cure.
