Peanut culturing device and system as well as authenticating method for drought resistant peanut varieties

Abstract

The invention provides a peanut culturing device. The peanut culturing device is provided with a hollow water-proof main body; the main body comprises a first main body and a second main body which are symmetric to each other along a central axis of the main body; a gap filled with glass cement is formed between the first main body and the second main body; a sealing film is arranged at one end of the main body; and the exterior of the sealing film is bound by using a fixing rope so as to seal the end part of the main body. The invention further provides a peanut culturing system; the system is provided with a culturing pool with an awning above; and the peanut culturing device is placed in the culturing pool. The invention further provides a method for authenticating root morphological characteristics of drought resistant peanut varieties on the basis of the peanut culturing device. According to the invention, quantitative indexes, which are changed with development progress under slight water stress, of roots of the different drought resistant peanut varieties can be accurately detected; the root morphological characteristics of the drought resistant peanut varieties are authenticated through comparing the root morphological characteristics of the different drought resistant peanut varieties; moreover, the whole peanut culturing device and system are simply structured, the detecting method is simple and convenient in operation, and accurate and reliable results are obtained.

Description

【Technical field】 [0001] The invention relates to an identification method for drought-resistant peanut varieties, in particular to a peanut cultivation device and system and an identification method for root system morphological characteristics of drought-resistant peanut varieties. 【Background technique】 [0002] Peanut is an important oil crop and economic crop. my country's peanut production areas are mainly distributed in arid and semi-arid areas, ancient river courses, hilly slopes and other places. Drought has become one of the most widely distributed and most harmful limiting factors in peanut production in my country. The annual reduction rate of peanuts caused by drought in the country is above 20%, and the economic loss exceeds 5 billion yuan. Important factor in aspergillus infection. Therefore, cultivating and selecting drought-resistant peanut varieties is one of the key issues that must be prioritized to promote the further development of peanut production. ...

Problems solved by technology

[0004] At present, due to the unintuitive nature of the root-soil system and the limitations of root research methods, the research on the morphology of the peanut root system is progressing slowly. Although some research results have been obtained, there are many shortcomings and deficiencies.

For example, 1) mainly focus...
