Composite liquid fertilizer for injection of fruit stem and its production process

Abstract

The liquid fertilizer contains several nutritious elements and is compounded with urea, potassium nitrate, ferrous sulfate, zinc sulfate, magnesium sulfate, manganese sulfate, boric acid, potassium dihydrogen phosphate, calcium nitrate, copper sulfate, citric acid and water. It has less pollution of soil and underground water, can regulate the balance between the nutritious elements inside tree body and may be produced in simple process, at low cost and high production efficiency.

Description

Technical field: [0001] The invention belongs to the field of fertilizers, in particular to a compound liquid fertilizer for fruit tree trunk injection and a preparation method thereof. Background technique: [0002] Fruit trees are perennial woody plants with strong branch skeletons and the characteristics of storing nutrients. The root system of fruit trees is well developed, and the distribution is deep and wide. Once they have been planted for many years, they will selectively absorb nutrients from the same soil for a long time, which will easily lead to insufficient supply of soil nutrients, and physiological obstacles such as nutritional disorders and deficiencies. Therefore, carrying out fertilization management to fruit trees is one of important links in fruit tree cultivation. The traditional method of fertilizing fruit trees adopts soil fertilization and foliar spray fertilizer. These fertilization methods have many defects, such as soil fertilization with a large...
