Composition for preventing and treating fruit-cracking disease, sunscald and navel orange yellowing disease of crop fruits as well as preparation method thereof

Abstract

The invention discloses a combination for prevention and cure of the disease of dehiscent fruit, sunscorch and yellow-navel disease. The combination is prepared with raw materials with the following weight percentage: 0.5-0.7 percent of EDDHA-Fe, 0.7-1.3 percent of EDTA zinc-titanium, 3.0-4.2 percent of EDTA manganese-titanium, 1.0-1.5 percent of EDTA calcium- titanium, 2.5-3.5 percent of high polymerized sulfonated naphthalene formaldehyde, 0.3-0.7 percent of EDTA titanium and 88-92 percent of deionized water. The invention has the advantages of that: 1) after the product is sprayed on the crops, the flexibility and expansion strength of the fruit skin can be improved, and the phenomenon of dehiscent fruit due to the poor flexibility of the fruit skin is avoided; besides, the effective constituents of the invention carry large quantity of moisture to penetrate from the foliages toward the fruits rapidly supplement the fruit moisture, and as a result, sunscorch is avoided; 2) the product is capable to enhance the adverse-resisting property of the plant, increase the anti-disease capability so that to achieve the effects of prevention and cure of dehiscent fruit, sunscorch and yellow-navel; 3) the invention is capable to improve the activity of microelements and enhance the microelement absorbing capacity of the plant.

Description

technical field [0001] The invention relates to a composition for preventing and treating physiological diseases of crop fruits and a preparation method thereof, in particular to a composition for preventing and treating fruit cracking disease, sunburn and navel yellow disease of crop fruits and a preparation method thereof. Background technique [0002] Fruit cracking disease, sunburn and navel yellow disease are the three major physiological diseases of fruit trees, which seriously endanger the growth and development of fruit trees and the yield and quality of fruits. The mild ones will cause quality decline and production reduction, and the severe ones will cause no harvest. [0003] The cause of fruit cracking disease is: 1) It is caused by the imbalance of soil moisture, that is, in the growth process of the fruit, the soil is too dry in the early stage, the fruit tissue is less elastic, and the soil moisture suddenly increases in the later stage, such as continuous rain...

2) Due to the poor toughness of the peel, the fruit pulp is arranged too tightly, and the fruit particles are squeezed each other, resulting in cracking
