Problems solved by technology

However, hydroponics is prone to root rot due to anaerobic respiration of plant roots.
[0005] Therefore lack a kind of method that cultivation environment is easy to control and plant is not easy to rot, easy to operate the screening salt-tolerant muskmelon variety

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 muskmelon varieties, specifically comprising the following steps:

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

Abstract

The invention provides a method for screening salt-resistant muskmelon varieties. According to the method, full, regular and not-damaged seeds are selected from different varieties of muskmelon seeds and are subjected to sand culture planting by the same planting substrate; after the sowing for a period of time, young seedlings with the consistent growth vigor are selected and transplanted to an aeroponic culture turnover box containing a 1 / 2 Hoagland nutrient solution to be cultured into muskmelon plants; the plants with three leaves, one center and identical growth are selected; the main root length X1 is recorded; the plants are divided into a salt treatment group and a blank control group; the blank control group still uses the 1 / 2 Hoagland nutrient solution for aeroponic culture; the salt treatment group uses the 1 / 2 Hoagland nutrient solution added with 150mmol / L of NaCl for aeroponic culture. After the preset time, the main root length of muskmelons of the salt treatment group and the blank control group is respectively determined; salt-resistant muskmelon varieties can be screened out through analysis contrast on main root length data. 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 muskmelon varieties, in particular to a method for screening salt-tolerant muskmelon varieties. Background technique [0002] Freshwater resources are scarce in western my country, but there are a large number of saline-alkali land and brackish water resources. As an important economic crop in the western region, melon is restricted by saline-alkali conditions. Salt-tolerant melon varieties need to be bred as pioneer varieties in saline-alkaline areas. This is of great significance to the rational development of saline-alkali land and brackish water resources in the western region, and the promotion of social and economic progress and ecological environmental protection in the western region. [0003] For a long time, the screening or identification of saline-alkali-tolerant melons have been carried out in field saline-alkali land and artificial salt ponds, or some physiological and biochemical parameters...
