Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] A method for screening salt-tolerant watermelon varieties, specifically comprising the following steps:

[0028] Seed selection: The plump, neat and undamaged seeds were selected from different varieties of watermelon seeds to be planted in sand culture respectively, and the planting substrate was mixed with fine sand and sieved farmland soil at 2:1. The plump, neat and undamaged seeds were selected from the watermelon seeds of different varieties to be planted in sand culture with the same planting substrate, which ensured the germination rate of the watermelon seeds...

Abstract

The invention provides a method for screening salt-tolerant watermelon varieties. According to the method, full, regular and damage-free seeds are selected from different varieties of watermelon seeds and are subjected to sand culture planting by same planting substrates; after the sowing for a period of time, seedlings with consistent growth vigor are selected and are transplanted to an areoponics culture turnover box containing 1 / 2Hoagland nutrient solution to be cultured into watermelon plants; plants with two leaves, one center and consistent growth are selected, then, the plant heights X1 are recorded, and the plants are divided into a salt treatment group and a blank control group; the blank control group still uses the 1 / 2Hoagland nutrient solution for areoponics culture; the salt treatment group uses 1 / 2Hoagland nutrient solution of 100mmol / L of NaCl for areoponics culture. After the preset time, watermelon seedlings in the salt treatment group and the blank control group are subjected to plant height determination; watermelon varieties with high salt-tolerant performance can be screened through plant height data analysis and comparison. The method has the advantages that the cost is low; the operation is easy; the method can be conveniently popularized and implemented in each place.

Description

technical field [0001] The invention relates to a method for screening watermelon varieties, in particular to a method for screening salt-tolerant watermelon varieties. Background technique [0002] Watermelon is an annual vine herb of Cucurbitaceae and is one of the most widely cultivated fruits in the world. Watermelon is a fruit with a long history of cultivation in the world. It has a high yield and has the characteristics of drought tolerance, salt tolerance, and barrenness tolerance. However, there are large differences in salt tolerance among different varieties of watermelon. Due to the restriction of soil salinization, the cultivation of watermelon has been seriously affected. Watermelon itself has certain characteristics of salt-alkali tolerance. After salt-tolerant breeding, it can be used as a pioneer crop for improving the utilization of saline-alkali soil and developing the economy in saline-alkali areas. [0003] For a long time, the screening or identificat...
