Fertilizing method for improving fertilizer effect of microelement and application

Abstract

The invention provides a fertilizing method which can improve the manurial effect of a trace element, in particular relates to furrowing (or holing) fertilization, comprising the following steps: half of acid medium is put in every dressing furrow (or hole), trace element fertilizer is put inside, and then the other half of acid medium is put inside. The acid medium is red loam, or peat bog or fertilizer, such as decomposed pig manure, chicken manure, etc. The application ratio of the trace element fertilizer and the acid medium is determined by climate, soil and plant. By adopting the method, root field soil pH can be decreased to lead the trace element fertilizer to be effective steadily for a long time, and over-high local concentration of the trace element can be effectively avoided; microbial activity of the soil is improved, which is favourable for the absorption of micro-nutrient by a root system and transportation in a tree, the physiological passivation of the trace element is eliminated, and the activity thereof is improved; growing conditions of the tree is improved, nutritive equilibrium is promoted, and tree vigor is strengthened; and trace element nutrient deficiencysymptom of the tree can be controlled, and quality fruit with relatively high content of the trace element can be produced. The method can be applied to the control of calcareous soil woody plants which lack the trace element.

Description

technical field [0001] The invention belongs to a fertilization method, and relates to a fertilization method and application for improving the fertilizer efficiency of trace elements of woody plants in calcareous soil. Background technique [0002] Woody plants refer to perennial plants whose roots and stems thicken and grow to form a large amount of xylem, and the cell walls are also mostly lignified. Woody plants have well-developed xylem and hard stems. During their growth and development, only when the concentration and proportion of various nutrients in the soil are moderate and balanced can the best growth and yield quality be obtained. However, due to various obstacles in the soil that limit the absorption of nutrient elements by the root system, and the interaction between various elements, it is difficult to achieve or maintain this nutrient balance state. Fertilization can adjust the balance of mineral elements in the tree body and promote The tree grows and deve...

Problems solved by technology

However, foliar spraying has the characteristics of large amount of medicine required, easy to cause environmental pollution, and difficult to ensure uniform spraying; high-pressure injection has problems such as complicated operation, easy to form fertilizer damage, and physical wounds will cause local serious damage to the trunk; infusion method and Although the root cutting method has quick results, it does not last long

Due to the narrow concentration range of trace elements suitable for tree growth, excessive application, too little or improper application methods will affect the normal growth of trees, and even cause poisonous damage, which will bring losses to producers.
