Description

A device for identifying salt tolerance in pepper seedling stage

technical field

The utility model belongs to the technical field of crop salt tolerance identification, in particular to a salt tolerance identification device for pepper seedlings.

Background technique

The area of saline-alkali land in China ranks third in the world, and the total area of saline-alkali land affecting arable land has exceeded 500 million mu. The rational use of mild and moderate saline-alkali land will greatly expand the scope of land use. Pepper is a vegetable species with strong salt tolerance, and the salt tolerance varies greatly among varieties, and it is also one of the important economical cultivated crops. In recent years, due to saline-alkali soil, years of planting in facilities and improper fertilization, the growth obstacles have become increasingly serious, resulting in poor root growth of peppers, slow plant growth, and significantly reduced yield and quality. Therefore, identification and screening of pepper varieties with strong salt tolerance and breeding of salt-tolerant pepper varieties have become the key to adapt to soil salinization and improve the utilization of saline-alkali land.

Studies have shown that the seedling stage is one of the salt-sensitive periods of plants, so the salt tolerance identification of peppers is effective in the seedling stage. The identification of vegetable salt tolerance is to identify the salt tolerance of vegetables based on changes in plant morphological indicators or physiological and biochemical indicators under salt stress. Different vegetables have different identification indicators. Although some indicators can be used for reference, there will be differences in the identification results, which will affect breeding. Salt tolerance evaluation of materials. At present, there are patent reports on salt tolerance identification devices for wheat, rice and other crops, but they are not applicable to peppers, and there are almost no reports on salt tolerance identification devices for peppers. Therefore, salt tolerance identification devices for pepper seedlings are urgently needed.

For salt tolerance identification at the seedling stage, the conventional method is to use a plastic box as a hydroponic device, then select a foam board to fix the seedlings, select the appropriate aperture according to the needs of the crop, and finally add salt solution and Distilled water for salt tolerance identification, this is a simple seedling stage hydroponic device; the advantages of this device are that it is convenient to obtain materials, low cost, and the identification results are representative. To a certain extent, the salt tolerance of the seedling stage can be set according to your own needs. device. But there are also many shortcomings: 1. The traditional simple hydroponic identification box is a randomly selected foam box or plastic box. Although the material is convenient and the cost is low, it cannot meet the requirements of the growth environment such as the root oxygen of pepper seedlings; 2. The structure of the fixed seedlings in the traditional identification box generally has a fixed aperture size, which leads to the lodging of pepper seedlings in the early stage of identification, which restricts the growth of stems in the later stage. Breeding materials, when there are too many breeding materials, can not meet the support force when the seedling growth is large; 4. The general salt tolerance identification device needs to be equipped with two treatments of distilled water and salt solution to identify the salt tolerance of the plants. The usual method is Set up two plastic boxes or foam boxes, one for clear water control and the other for salt treatment. When there are few breeding materials, there is a lot of space left in the plastic box, which is easy to cause waste; 5. Salt solution in the salt tolerance identification box Water evaporates quickly. If the salt solution is not replenished in time or quantitatively, it will easily lead to changes in the rock concentration in the identification environment, which directly affects the accuracy of the identification results; 6. The traditional simple device has a short service life and poor repeated use. In conclusion, there is an urgent need for a salt-tolerance identification device for pepper, which can efficiently and accurately evaluate salt-tolerance and screen salt-tolerant pepper varieties for a large number of pepper breeding materials.
