Problems solved by technology

After the 1970s, it was gradually used for the correction of iron deficiency chlorosis of woody plants such as fruit trees and the production of other deficiency diseases and trace element-rich fruits (such as selenium-enriched fruit and high-iodine fruit). Aiming at one element, supplementing a single element for the tree body often causes an imbalance of the proportion of elements in the tree, and while solving a certain deficiency disease, it causes a new imbalance or even imbalance among the nutritional elements in the tree, which cannot reach The purpose of increasing production and income

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...
