Mango flower-promoting and fruit-preserving fertilizer and its preparation method and application method

Abstract

The invention provides a mango flower-promoting and fruit-preserving fertilizer. According to parts by weight, its active components include: 0.1-0.3 parts of polyaspartic acid, 0.2-0.8 parts of chitosan oligosaccharide, and 0.05-0.2 parts of pyroxuron , 200-400 parts of potassium nitrate, 100-300 parts of calcium magnesium phosphate fertilizer, 10-30 parts of borax fertilizer, and 5-20 parts of zinc sulfate. All the components of the mango flower promoting and fruit preserving fertilizer are uniformly mixed to obtain the obtained mango. The special fertilizer of the present invention has no pollution to the environment and is harmless to the human body. It has comprehensive nutrition and is easy to absorb. It can be absorbed through foliage spraying and root irrigation, etc., can greatly improve the photosynthesis of plants, improve resistance, and can effectively Improve mango's absorption of potassium, magnesium, calcium, boron, zinc and other nutrients, promote mango reproductive development and nutritional development, promote mango flowering, increase fruit setting rate and yield, and improve fruit quality.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizers, in particular to a mango flower-promoting and fruit-preserving fertilizer and a preparation method and application method thereof. Background technique [0002] Generally, it takes a long time for mango to bloom naturally, and there are two flowering characteristics. Especially in off-season cultivation, flowering occurs first and then, coupled with low fruit setting rate and difficult fruit preservation. Therefore, mango catalytic fruit preservation directly affects The formation of flowering period, flowering uniformity, fruit setting rate and fruit quality, etc. Therefore, the mango flower-promoting and fruit-preserving fertilizer product has been produced. At present, there are some flower-inducing and fruit-preserving products on the market that use a single flower-inducing and fruit-preserving drug, such as paclobutrazol, ethephon, potassium nitrate, 920 and other products....

AI Technical Summary

Problems solved by technology

[0003] In the off-season mango cultivation and management process, it is difficult to achieve early flowering of mangoes with a single flower-promoting and fruit-preserving fertilizer (medicine), and the flowering uniformity is not high, and the effect of improving fruit setting rate and fruit quality is extremely limited.

In addition, for single drugs such as paclobutrazol and 920, it is difficult to grasp the concentration and frequency of use, and at the same time, it decomposes slowly. Most of paclobutrazol is applied to the soil and remains in the soil for a long time. Drug poisoning, resulting in a large number of short inflorescences, large flower clusters, deformed leaves, etc., also affects fruit quality
