Method and device for batch identification of wheat salt tolerance

Abstract

The invention discloses a method and device for identification of plant salt tolerance. The device comprises a box body of which the upper end is open, wherein a plurality of pipelines are disposed in the box body, the positions of the pipelines are adjustable, and two ends of each pipeline are open; and the pipelines are disposed in the box body by a pipe frame, and a spacing is formed between the lower end opening of each pipeline and the bottom part of the box body. The method for the batch identification of wheat salt tolerance with application of the device comprises the steps that (1) soil is put in the pipelines in the device; (2) seeds of to-be-identified wheat are planted in the pipelines; (3) the pipelines are placed in the box body by the pipe frame, wherein a nutrient solution is stored in the box body, and the lower ends of the pipelines are soaked in the nutrient solution; and (4) the batch identification of the wheat salt tolerance can be realized through had justment and control of the salt content of the nutrient solution. The method is widely applicable to the salt tolerance identification of wheat germplasm resources, genetic materials and new varieties (species).

Description

technical field [0001] The invention relates to a method and a device for identifying the salt tolerance of plants, in particular to a method and a device for identifying the salt tolerance of wheat in batches. Background technique [0002] Soil salinization is a worldwide resource and ecological problem. According to statistics, the area of ​​saline soil in the world is 954.38 million hectares, and saline soil is widely distributed in my country, with a total area of ​​1.487 billion mu (about 100 million hectares). Rational use of salinized soil resources is an urgent problem in my country's agricultural development. There are many ways to develop and utilize salinized soil, and planting salt-tolerant crop varieties is one of the cost-effective ways. Wheat is the second largest food crop in the world, and it is also one of the main cultivated crops in saline soil in my country. Soil salinization seriously affects wheat yield. Therefore, breeding salt-tolerant wheat varie...

AI Technical Summary

Problems solved by technology

Although the identification of salt tolerance in hydroponics can make wheat seedlings quickly develop salt stress phenotypes, which can partially reflect the salt tolerance characteristics of wheat seedlings, but a single hydroponic condition cannot simulate the normal growth environment of wheat seedlings, and there are many shortcomings

For example, since the base of the seedling grows in the hole of the bubble film, the tight space will limit the tillering and growth of wheat

Moreover, since the wheat seedlings cannot change the planting position once transplanted into the bubble film board, it is impossible to eliminate the differences in the cultivation conditions such as light and temperature, and ensure the consistency of the experimental conditions of each individual plant

In addition, the steps of this method are relatively cumbersome, and the seedlings need to be transplanted before hydroponics. When the seedlings grow up, they will fall due to lack of support, and must be transplanted into soil culture conditions again to reproduce.
