Method for promoting fruit setting of jujube trees in arid regions and special preparation thereof

Abstract

The invention discloses a method for promoting fruit setting of jujube trees in arid regions and a special preparation of the method. According to the method for promoting the fruit setting of the jujube trees in the arid regions and the special preparation of the method, 5-aminolevulinic acid, bromine, thidiazuron, boric acid, FeSO4CuSO4, zinc sulfate, manganese sulfate and sodium sulfate are prepared to form a solution with the concentration of 0.2% to 0.4%; and the solution is sprayed on the jujube trees in 15 to 25 days after the jujube trees start to blossom. Compared with a traditional method, the method for promoting the fruit setting of the jujube trees in the arid regions and the special preparation of the method have an obvious promoting effect on the fruit setting, the fruit setting rate is generally improved by 35%, the fruit protection rate is particularly and remarkably improved, and the commodity rate of jujube fruits can be improved remarkably; and meanwhile, the mixed preparation is composed of biological agents and inorganic substances, is harmless to human body and high in safety, has the advantages of being convenient to use and stable in effect, and has quite broad application prospects.

Description

technical field [0001] The invention relates to the field of jujube high-yield cultivation, and more specifically relates to a method for promoting fruit setting of jujube trees in arid areas and a special plant growth regulator for the method. Background technique [0002] Jujube is a unique economic tree species in my country, and its current area has reached 1.5 million hectares. It is the largest dry fruit tree species in my country. In recent years, Xinjiang has become a new jujube plantation area due to its natural environment and geographical advantages, and the jujubes produced are of high quality. However, although the amount of jujube flowers is large, the natural fruit setting rate is only about 2%, especially when the humidity is too low (less than 50%) during the flowering period, it will inhibit the germination of jujube pollen. The healthy development of the jujube industry has been ensured. [0003] Among the existing known technologies, the most widely use...

Problems solved by technology

GA 3 It is a broad-spectrum growth-promoting substance, which has a significant effect on promoting fruit setting on jujube trees, but it can easily cause jujube hangings to accelerate growth and form nutritional competition, causing the young fruits to fall off easily, especially in arid areas affected by air humidity. The application effect is unstable
