Problems solved by technology

[0003] The mountainous and hilly areas in southern my country are the main production areas of tropical and subtropical fruits in my country. Fruits are the main pillar industry of farmers' economic income in this area; Shallow, hard texture, many gravels, it is difficult to use ditch (hole) fertilization method and it will greatly damage the green turf, the utilization rate of fertilizer is very low, the fertilizer efficiency is poor, and the conventional fertilization is difficult or the fertilizer efficiency is not high. A major problem in the survival and normal growth of garden trees

Embodiment 1

[0020] Embodiment 1: longan test

[0021] (1) Experimental design

[0022] The test was arranged in Nanrongtang Village, Xindu Town, Putian City, and the soil fertility for the test was medium. There were 11 treatments in the test, namely: treatment 1: spreading (CK1), treatment 2: furrow application (CK2), treatment 3: hole application (3 fertilization holes, hole depth 20 cm), treatment 4: hole application (3 Fertilization holes, hole depth 40cm), treatment 5: hole application (3 fertilizer holes, hole depth 60cm), treatment 6: hole application (4 fertilizer holes, hole depth 20cm), treatment 7: hole application (4 fertilizer holes , hole depth 40cm), treatment 8: hole application (4 fertilization holes, hole depth 60cm), treatment 9: hole application (5 fertilization holes, hole depth 20cm), treatment 10: hole application (5 fertilization holes, hole 40cm deep), treatment 11: hole application (5 fertilization holes, 60cm deep); represented by T1~T11 respectively.

Abstract

The invention discloses a nutrient carrier material with functions of looseness, air permeability, water retention and fertilizer retention, and its formula is a ternary compound fertilizer of quartz sand, perlite and attapulgite. The application method of the invention is a new type of fertilizer supply technology for the full plow layer of horticultural trees. The invention can not only effectively improve fertilizer utilization rate, reduce labor intensity, reduce environmental pollution and increase labor benefit, but also is expected to improve fruit yield and quality, and has important practical significance for promoting farmers' income increase, agricultural efficiency enhancement, rural development and urban greening.

Description

technical field [0001] The invention belongs to the technical field of plant fertilization, and in particular relates to a nutrient carrier material which has the functions of looseness, air permeability, water retention and fertilizer retention, and is conducive to rapid and uniform diffusion of nutrients inside. Background technique [0002] Fertilization is a major task in horticultural tree management. Whether the method of fertilization is reasonable or not directly affects tree growth, fruit yield and quality, and economic and social benefits. At present, tree fertilization methods mainly include spreading, furrow and hole application. Spreading, although labor-saving and time-saving, tends to make the root system shallower, reduce the stress resistance of trees, and cause a large loss of nutrients. Not only the fertilizer utilization rate is low, but also the eutrophication of the water body and the greenhouse effect will be exacerbated. Furrow fertilization or hole ...
