Disease prevention and frost resistance fruit selenium-enriching nutritional agent for fruit trees and preparation method of disease prevention and frost resistance fruit selenium-enriching nutritional agent

Abstract

The invention discloses a disease prevention and frost resistance fruit selenium-enriching nutritional agent for fruit trees and a preparation method of the disease prevention and frost resistance fruit selenium-enriching nutritional agent. The nutritional agent consists of the following components in part by weight: 20-40 parts of urea, 5-20 parts of ammonium dihydrogen phosphate, 35-65 parts of potassium dihydrogen phosphate, 15-35 parts of a boron fertilizer, 7-15 parts of a selenium fertilizer, 3-8 parts of salicylic acid, 1-3 parts of captopril, 4-10 parts of humic acid, 3-5 parts of pyrazinamide, 2-6 parts of metronidazole, 10-20 parts of paclobutrazol, 0.4-1 part of methylglutarate and 0.5-2 parts of disopyramide phosphate. The selenium-enriching nutritional agent disclosed by the invention has strong pertinence, can be used for solving multiple prominent problems existing in the planting of the fruit trees simultaneously, and has multiple effects such as disease prevention, rotten fruit prevention, frost resistance, dehiscent fruit prevention, fruit dropping prevention, fruit plumpness promotion, nutrition, selenium enrichment and the like.

Description

Technical field [0001] The invention belongs to the technical field of fertilizers, and particularly relates to a selenium-enriched nutrient for preventing disease, freezing and promoting fruit for fruit trees, and a preparation method of the nutrient. Background technique [0002] At present, most of the selenium-enriched fertilizers are broad-spectrum. One product is suitable for various crops, fruits, etc. It is not highly targeted and has weak matching with the growth characteristics of the crop; its function is relatively single, and the main function is enrichment Increase vitamins, increase sweetness, increase production, etc., and the effect of increasing production and sweetening is not ideal; it cannot simultaneously solve the prominent problems in fruit tree planting, such as disease, rotten fruit, freezing damage, insufficient fruit, fruit cracking, serious fruit drop, etc. [0003] Aiming at the current selenium-enriched fertilizers that are not highly targeted, have r...

Problems solved by technology

[0002] At present, most of the selenium-enriched fertilizers are broad-spectrum. One product is suitable for various crops, melons and fruits, etc., which is not highly targeted and has a weak match with the growth characteristics of crops; Increase vitamins, increase sweetness, increase production, etc., and the effects of increasing production and sweetening are not ideal; it cannot solve the outstanding problems in fruit tree planting at the same time, such as disease, rotten fruit, freezing damage, unfulfilled fruit, cracked fruit, severe fruit drop, etc.

[0003] In view of the lack of pertinence, single function and inability to solve outstanding problems in fruit tree planting in current selenium-enriched fertilizers, the present invention provides a kind of anti-disease, anti-rotten fruit, anti-freezing damage, anti-cracking fruit, anti-dropping fruit, Selenium-enriched nutrition agent for fruit tree disease prevention, anti-freeze, and fruit-enriched selenium, which can promote fruit plumpness, nutrition, and selenium-enrichment
