Water-soluble fertilizer for preventing fruit cracking of fruit trees

Abstract

The invention relates to a water-soluble fertilizer for preventing fruit cracking of fruit trees. The water-soluble fertilizer comprises the following effective components: 0.2 parts of gibberellin GA3, 0.5 parts of polyglutamic acid, 8-10 parts of N, 10-13 parts of P2O5, 30-32 parts of K2O, 2-3 parts of Ca, 0.1-0.3 parts of Fe, 0.2-0.3 parts of B, 0.1-0.3 parts of Cu, and 0.1-0.3 parts of Mn; the N is provided by one or more of urea, monoammonium phosphate, potassium nitrate and calcium nitrate, P2O5 is provided by one or two of potassium dihydrogen phosphate and monoammonium phosphate, K2O is provided by potassium nitrate and potassium dihydrogen phosphate, Fe is provided by ferrous sulphate, Zn is provided by zinc sulfate, B is provided by boric acid, Cu is provided by copper sulphate, Ca is provided by calcium nitrate, and Mn is provided by manganese sulfate. The water-soluble fertilizer can enhance the fruit tree resistance performance, increases the output, increases the quality, and prevents the fruit cracking.

Description

technical field [0001] The invention relates to a water-soluble fertilizer for preventing fruit tree cracking and a preparation method thereof. Background technique [0002] A large number of studies have shown that fruits are rich in antioxidant vitamin E, trace elements and a large number of other natural plant compounds. These substances can regulate the activity of detoxification enzymes, improve hormone metabolism, have antibacterial and antiviral capabilities, and play a role in delaying aging . Since fruits contain many vitamins and trace elements, they can also be used to prevent diseases. Fruits prevent and treat cardiovascular diseases, and can inhibit the growth of strong carcinogen nitrosamines and the proliferation of cancer cells, and produce certain enzyme activities. According to data analysis, fruits can improve digestion, improve myocardial function, and play a regulating role in maintaining acid-base balance in the human body. Some fruits are rich in di...

Problems solved by technology

At present, in the process of planting fruit trees, the fertilizers used are mainly potassium sulfate-type compound fertilizers or compound fertilizers combined with farmyard manure, and sulfur-based organic-inorganic compound fertilizers are also used, but with these types of fertilizers being used in large quantities, Nitrogen, phosphorus and potassium nutrients form antagonism with some trace elements in the soil, and the continuous intake of trace elements in the soil by fruit trees planted year after year leads to the lack of trace elements in the soil that can be absorbed by fruit trees, and the occurrence of physiological diseases of fruit trees As a result, the quality of fruits in older orchards continues to decline, and the economic benefits continue to decrease. Many orchards have to cut down fruit trees and close orchards, especially in the middle and late growth stages of fruit trees. Symptoms of deficiencies such as diseased fruit cracking appear, because it will seriously affect the appearance quality of the fruit, and after the cracking, the fruit is prone to storage diseases to varying degrees, thereby shortening the storage period and shelf life of the fruit, so it often causes major economic losses to production
