Horticultural tree full-plow-layer stereo fertilization method

Abstract

The invention discloses a horticultural tree full-plow-layer stereo fertilization method. According to the method, fertilization holes are drilled around a tree-crown drip line of a horticultural tree; a PVC pipe is arranged in each fertilization hole; and a nutrient carrier material with loosening, ventilation, water retention and fertilizer retention functions, fertilizers needed for the tree, and water are applied into the fertilization holes together. Therefore, fertilizer nutrients can quickly spread into the nutrient carrier material in the hole in a condition with sufficient water, and nutrients can be continuously provided for tree roots at different soil layers. With the method, fertilizer utilization rate can be effectively improved; labor intensity can be reduced; environment pollution can be reduced; labor benefit can be improved; and fruit yield and quality can be improved. Also, farmer income increase, agricultural efficiency increase, rural development and city greening processes can be effectively promoted.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a full-plow three-dimensional fertilization technology of horticultural trees and a use method thereof. Background technique [0002] Fruits and landscaping seedlings are the main pillar industries of my country's farmers' economic income. China is the world's largest fruit producer. According to statistics, in 2013, the sown area of ​​orchards in my country reached 11.1395 million hm 2 , the total fruit output reached 200 million tons, ranking first in the world; in 2013, my country's fruit trade surplus reached 2.2 billion US dollars. At the same time, with the acceleration of my country's urbanization process and the improvement of people's living standards, the people's demand for greening the living environment is increasing day by day, and the landscaping industry is changing with each passing day, with broad prospects for development. [0003] The current fertiliz...

AI Technical Summary

Problems solved by technology

The landscaping belt has a shallow soil layer, hard texture, and many gravels. It is difficult to fertilize in trenches (holes), and the labor cost is high. Nutrients are easy to be fixed. It is easy to cut off the horizontal root system of trees when ditching (cavity), and the scope of fertilization is small, which makes the root system float on the topsoil; although spreading fertilizer saves labor and time, it is easy to make the root system shallow and reduce the stress resistance of the tree. Very low yield, poor fertilizer efficiency

Difficulty in conventional fertilization or low fertilizer efficiency is a major problem hindering the survival and normal growth of garden trees
