Special foliar fertilizer for ginkgo trees and preparation method of foliar fertilizer

Abstract

The invention discloses special foliar fertilizer for ginkgo trees. The foliar fertilizer is prepared from components in parts by mass as follows: 16-20 parts of urea, 10-12 parts of monopotassium phosphate, 2-4 parts of manganese sulfate monohydrate, 5-10 parts of calcium carbonate, 4-8 parts of magnesium sulfate, 5-7 parts of ferrous sulfate, 3-6 parts of zinc sulfate, 3-9 parts of anhydrous copper sulfate, 3-5 parts of sodium borate, 4-8 parts of a plant amino acid preparation and 200-320 parts of deionized water. With the adoption of the foliar fertilizer, growth condition of the ginkgo trees can be improved effectively, the probability of malnutrition is reduced, planting functions of the ginkgo trees in various aspects are improved, and the adopted preparation is safe and non-toxic and produces no harm to the safety of the environment and people.

Description

technical field [0001] The invention relates to a plant fertilizer, in particular to a special foliage fertilizer for ginkgo trees and a preparation method thereof. Background technique [0002] Ginkgo biloba is a deciduous tree belonging to the Ginkgo family and the genus Ginkgo. Ginkgo is a large deciduous tree with a DBH of up to 4 meters. The bark of young trees is nearly smooth and light gray, and the bark of large trees is taupe, irregularly split and rough; there are long branches and slow-growing short branches. The crown of the tree is conical in young and middle-aged adults, and broadly oval in old age; the branches grow in whorls and extend obliquely. The fruit of the ginkgo tree is commonly known as ginkgo, so ginkgo is also called ginkgo tree. Ginkgo trees grow slowly and have a very long lifespan. Under natural conditions, it takes more than 20 years from planting to bearing ginkgo fruit, and it takes 40 years to bear fruit in large quantities. However, during...

Problems solved by technology

Ginkgo trees grow slowly and have a very long lifespan. Under natural conditions, it takes more than 20 years from planting to bearing ginkgo fruit, and it takes 40 years to bear fruit in large quantities. However, during the planting process of ginkgo trees, the root system of the plant is relatively deep, and traditional fertilizers Limited utility, resulting in reduced fertilizer use efficiency, while heavy use can cause serious environmental problems
