Abstract

The invention discloses composite fertilizer for planting fruit trees and a preparation method thereof and belongs to the technical field of agricultural fertilizer. The composite fertilizer is prepared from, by weight, 30-42 parts of urea, 20-35 parts of calcium superphosphate, 18-33 parts of potassium sulfate, 40-55 parts of organic fertilizer, 15-24 parts of trace elements, 20-30 parts of tobacco waste, 16-30 parts of starch, 14-25 parts of fruit charcoal and 8-15 parts of water retaining agent. The invention also provides the preparation method of the composite fertilizer. The composite fertilizer is comprehensive in nutrient and capable of effectively preventing diseases and damage and increasing the yield of fruits.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a compound fertilizer for planting fruit trees and a preparation method thereof. Background technique [0002] The fruit tree is a perennial woody plant with a strong branch skeleton. The root system of the fruit tree is developed and the distribution is deep and wide. Once it has been fixed for many years, it will selectively absorb nutrients from the same soil for a long time, which will easily cause insufficient supply of soil nutrients. Physiological obstacles such as nutritional imbalance and deficiency syndrome are prone to occur. Therefore, the management of fertilization of fruit trees is an important part of fruit tree cultivation. At present, the commonly used compound fertilizers for fruit trees are mainly urea, diammonium phosphate, superphosphate, potassium sulfate, etc. . Common fruit tree compound fertilizers in the prior art have low fer...
