Flower-forcing and fruit-protecting fertilizer for mango and application method of flower-forcing and fruit-protecting fertilizer

Abstract

The invention provides a flower-forcing and fruit-protecting fertilizer for mango. The flower-forcing and fruit-protecting fertilizer comprises the following active components in parts by weight: 0.1-0.3 part of polyaspartic acid, 0.2-0.8 part of chitosan oligosaccharide, 0.05-0.2 part of forchlorfenuron, 200-400 parts of potassium nitrate, 100-300 parts of calcium magnesium phosphate, 10-30 parts of a borax fertilizer and 5-20 parts of zinc sulfate. The flower-forcing and fruit-protecting fertilizer is prepared by mixing all components of the flower-forcing and fruit-protecting fertilizer for mango evenly. The special fertilizer provided by the invention is free of pollution to environment, free of a harm to a human body, comprehensive in nutrient and easy to absorb, can be absorbed by foliar application, root irrigation and the like; the photosynthesis of plants can be greatly improved; the resistance is improved; absorption of the mango on the nutrient elements such as potassium, magnesium, calcium, boron and zinc can be effectively improved; reproductive development and nutrient development of the mango are promoted; flowering of the mango is promoted; the fruit setting rate and the content of the fruits are improved; and the fruit quality is improved.

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 urging 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
