Explosive column for blast soil loosening and fertilizer applying of fruit trees

Abstract

The invention discloses an explosive column for blast soil loosening and fertilizer applying of fruit trees. The explosive column comprises a housing, an explosive main charge and a fertilizer, wherein the housing is in the shape of a concave cylinder with an opening at the bottom end and is divided into two parts, namely an inner groove and an outer groove, the explosive main charge is arranged in the inner groove part, and the fertilizer is arranged in the outer groove part. The explosive column can realize the functions of blast soil loosening and fertilizer applying in different depths according to different varieties of the fruit trees and simultaneously prevent high temperature generated at the instant of explosion from damaging the fertilizer.

Description

technical field [0001] The invention belongs to the field of fruit tree fertilization, and in particular relates to a powder column for synchronously performing blasting loose soil and fertilization. Background technique [0002] Nowadays, with the development of the forest and fruit industry, the planting area of ​​fruit trees continues to expand, but within two to three years after the fruit trees are planted, soil compaction, hardening, and loss of fertility are caused by watering, which in turn affects the yield of fruit trees, or causes fruit trees to lose weight. The fruiting period ended early. The traditional solution is to use mechanical or manual methods to loosen the soil and fertilize. However, the shallow soil layer of these two methods is shallow and the fertilization effect is poor. At the same time, the root system of the fruit tree will be laid on the soil surface due to the shallow layer of loose soil, which will cause the fruit tree to resist wind. Reduce...

Problems solved by technology

[0002] Nowadays, with the development of the forest and fruit industry, the planting area of ​​fruit trees continues to expand, but within two to three years after the fruit trees are planted, soil compaction, hardening, and loss of fertility due to watering will affect the yield of fruit trees, or cause fruit trees. Early end of fruiting season

The traditional solution is to use mechanical or manual methods to loosen the soil and fertilize. However, the shallow soil layer of these two methods is shallow and the fertilization effect is poor. At the same time, the root system of the fruit tree will be laid on the soil surface due to the shallow layer of loose soil, which will cause the fruit tree to resist wind. Reduced ability

The method of blasting and loosening soil in the civil explosive industry is made by mixing explosives and fertilizers. The high temperature generated during the detonation of explosives reduces the effectiveness of fertilizers. At the same time, the addition of fertilizers often leads to a decline in the working ability of explosives, which in turn affects Loose soil quality
