Problems solved by technology

The taxonomic status of Tetragalus is very isolated, and the research on Tetraphyllum has been carried out before the establishment of the protected area, but people don’t know enough about it, and it itself is the main building group of vegetation in this area. The research and protection work is lagging behind, not only is it difficult to find its similar species, leading to the extinction of this rare and endangered plant, but also causing irreversible damage to the ecological environment
At present, the researchers' research on the breeding technology of Tetragalus mainly fo

Example Embodiment

[0009] Example 1:

[0010] When the quadrangle wood turns green, remove the dust on the quadrangle tree plants, choose a windless and sunny weather, and spray 4mg / L cytokinin (CTK) to the quadrangle tree plants according to the dosage (spray 100ml per square meter). Aqueous solution, no rainfall within three days after hormone spraying.

[0011] The thousand-grain weight and seed vigor of Tetragalus (seeds) were recorded when Tetragalus seeds matured. Among them, the thousand-grain weight without hormone injection was 1.0581g, while the thousand-grain weight of Tetragalus chinensis treated with 4mg / L cytokinin was 1.6232g, which was 53.4% ​​higher than that of the control strain, and its seed vigor was 6.7mg.g -1 .h -1 , the control is only 2.8mg.g -1 .h -1 , significantly higher than that of the control, thus effectively improving the thousand-grain weight and seed vigor of Tetragalus seeds.

Example Embodiment

[0012] Example 2:

[0013] When the quadrangle tree turns green, remove the dust on the quadrangle tree plants, choose a windless and sunny weather, and spray 250mg / L gibberellin (GA)+ on the quadrangle tree plants according to the dosage (spray 100ml per square meter) 4mg / L cytokinin (CTK) aqueous solution, no rainfall within three days after hormone spraying.

[0014] The thousand-grain weight and seed vigor of Tetragalus were recorded when Tetragalus seeds matured. The thousand-grain weight of not spraying hormone is 1.0581g, and the Sihemu thousand-grain weight after utilizing the aqueous solution treatment of 250mg / L gibberellin (GA)+4mg / L cytokinin (CTK) is 1.3123g, improves 24.0% than control strain, Its seed vigor is 7.1mg.g -1 .h -1 , the control is only 2.8mg.g -1 .h -1 , effectively improving the seed-setting properties of Tetragalus.

Abstract

The invention relates to a method for improving fruiting performance of tetraena mongolica maxim. The method is characterized by comprising the following steps of: when the tetraena mongolica maxim revives every year, removing dust on tetraena mongolica maxim plants, and spraying 100 ml of aqueous solution of 2-6mg/L cytokinin or 100 ml of aqueous solution of 200-400mg/L gibberellin and 2-6mg/L cytokinin per square meter of tetraena mongolica maxim plants in wind-free and sunny weather. The method has the benefits that the fruiting performance of the tetraena mongolica maxim can be improved by spraying exogenous hormones, thousand seed weight and vitality of seeds of the tetraena mongolica maxim are improved, the abortion rate of the seeds of the tetraena mongolica maxim is reduced, and the method is easy to operate and provides a new path for improving the current development and propagation situations of the tetraena mongolica maxim. According to the method, the growth and propagation performance of the tetraena mongolica maxim is controlled by using different plant growth hormones for the first time, and a new path is provided for improving the fruiting performance of the tetraena mongolica maxim and changing the endangered status of the tetraena mongolica maxim.

Description

technical field [0001] The invention relates to a method for improving the solid performance of quadruple wood. Background technique [0002] Tetraena mong olica Maxim is a small deciduous shrub of the family Zygophyllaceae. It is a relic species of the ancient Mediterranean 140 million years ago. It is known as the "giant panda" among plants and is a national first-class protected plant. Its distribution range is very narrow, and it is scattered in some parts of Russia and Ukraine in the world. The concentrated and contiguous growth of Sihemu only exists around Mahuanggou, the northernmost tip of Wuhai and Shizuishan Mountains in my country, and is a unique species in this area. In its distribution area, Tetragalus often becomes the construction species of desert communities. Its existence not only has important theoretical significance for understanding the ancient Mediterranean flora and the origin of vegetation, but also plays an important role in maintaining biodiversit...
