Method of determining formula of fruit tree formula fertilizer

Abstract

The invention discloses a method of determining a formula of a fruit tree formula fertilizer. The method comprises the following steps: determining an annual absorption operating law of fruit tree mineral nutrition, and drawing a fruit tree mineral nutrition annual absorption operating law drawing: determining demand quantities of a fruit tree for producing fruits with unit yield for elements including nitrogen, phosphorus, potassium, calcium and magnesium in each key growth and development stage through determination and analysis calculation, and drawing a fruit tree mineral nutrition annual absorption operating law drawing; and then carrying out a yearly '5416' orthogonal fertilizer applying experiment, namely 16 treated and optimized incompletely implemented orthogonal experiments with five elements which are the nitrogen, the phosphorus, the potassium, the calcium and the magnesium and control four levels including high level (1.5 times), middle level (1.0 time), low level (0.5 time) fertilizer applying quantity and 0 time. With adoption of the method, the demand quantities of fruit tree plants to the fertilizer such as the nitrogen, the phosphorus, the potassium, the calcium, the magnesium and the like in different growth and development stages, an optimum formula of the fertilizer application and the fertilizer applying quantity can be accurately obtained, and the method is suitable for being applied as a method of determining the formula of the fruit tree formula fertilizer.

Description

technical field [0001] The invention proposes a method for determining the formula of formula fertilizer for fruit trees in the field of agriculture and forestry. Background technique [0002] As of the end of 2015, the total area and output of fruit tree cultivation in my country ranked first in the world. my country has become the world's largest producer of fruit trees, and the fruit tree industry has become one of the pillar industries for farmers to increase their income and become rich and for rural economic development. However, at present, my country’s orchard nutrition and fertilization application foundation and application technology research is weak, fertilization management is mainly based on experience, fertilization technology is backward, and fertilizer utilization rate is low, resulting in orchard soil acidification, salinization and compaction increasing year by year, tree nutrition imbalance, Physiological diseases occur widely, seriously affecting the heal...

Problems solved by technology

[0003] In order to solve the problem of fruit tree formula fertilization and fertilizer efficient utilization, the present invention proposes a method for determining the formula of fruit tree formula fertilizer

This method first clarifies the absorption and operation rules of mineral nutrients in fruit trees, and then determines the optimal formula and fertilization amount of formula fertilizer for fruit trees based on the absorption and operation rules of mineral nutrients in fruit trees through orthogonal fertilization experiments, so as to solve the technical problems of formula fertilization and efficient utilization of fertilizers
