Problems solved by technology

The nutrient testing results showed that, except that the total nitrogen level of the soil tended to be balanced, the available phosphorus, exchangeable calcium and magnesium were all lower in the root diseased area than in the disease-free area, which fully explained the insufficient fertilizer supply capacity of the soil in the root diseased area. It is unfavorable to the growth and development of rubber trees and their root systems, greatly reducing the resistance of rubber trees to root diseases, which may be one of the reasons for the serious occurrence of root diseases

Abstract

The invention relates to the field of tree root disease prevention and control and concretely relates to a nutritional agent for preventing and treating rubber tree root diseases and a preparation method and use thereof. Each liter of the nutritional agent contains 0.07-0.15g of triadimefon, 0.20-0.30g of hymexazol, 0.65-1.25g of nutrition fertilizer and 0.02-0.05g of a rooting agent. The nutritional agent comprises potassium dihydrogen phosphate, potassium nitrate, calcium chloride and magnesium sulfate. The invention also discloses the preparation method and use of the nutritional agent. The nutritional agent can be used for preparing a preparation for preventing and treating the root diseases of a rubber tree, has substantial bactericidal and bacteriostatic effects after being used for plants infected with the root disease of the rubber tree, can promote the rapid growth of new roots of the diseased plant, can shorten the diseased plant recovery time and has a good prevention and treatment effects on rubber tree root diseases.

Description

technical field [0001] The invention relates to the field of forest tree root disease prevention and control, in particular to a nutritional agent for preventing and treating rubber tree root disease, a preparation method and application thereof. Background technique [0002] With the continuous increase of natural rubber planting area and planting years in my country, the replanting of the first and second generation old rubber plantations, the hazards of rubber tree root diseases are becoming more and more serious. At present, rubber tree root disease has become one of the three major destructive diseases of rubber trees, and it is a key factor limiting the increase of rubber per unit yield in my country. Rubber tree root disease is a root disease caused by fungi parasitic on the roots of rubber trees, and the pathogenic bacteria are Basidiomycotina and Ascomycotina fungi. The root diseases caused in my country mainly include red root disease, brown root disease, purple r...
