Abstract

The invention discloses a culture method for improving salt tolerance of eggplant by root fertilization of allogenic material 2,4-epibrassinolide. The culture method is characterized in that the salt-tolerant eggplant is obtained by root fertilization of 2,4-epibrassinolide (EBR, which is an important plant growth modifier) under the medium culture condition; on the basis of the root fertilization of different concentrations of allogenic material EBR, a method for selecting an optimal EBR concentration is adopted to obtain strong seedlings with strong salt tolerance and strong growth potential in seedling stage, and the screened optimal concentration is 0.05mg.L<-1>; the eggplant is a facility variety with weak salt tolerance; and the adopted culture mode is medium culture. The problems that facility eggplant has weak salt tolerance and weak seedling-stage growth potential can be solved by the mode of the root fertilization of allogenic material EBR.

Description

1. Technical field: [0001] The invention relates to a cultivation technique for improving salt tolerance of eggplant, in particular to a cultivation technique for improving salt tolerance of eggplant by root application of exogenous substance EBR. 2. Background technology: [0002] Secondary salinization of greenhouse soil is a common technical problem in protected cultivation at home and abroad. The threat of salt damage to eggplant is becoming more and more serious, resulting in a decline in its yield and quality, which seriously affects the sustainable development of its facility production. Among the methods to improve the salt tolerance of eggplant, external application of EBR is an effective method. Eggplant (Solanum melongena L.) is a vegetable crop that is moderately sensitive to salt, and its growth and yield will be seriously affected under saline conditions. Therefore, there is an urgent need for an effective method that can improve the salt tolerance of eggplan...
