Abstract

The invention solves a method of simultaneous fertilization and loosening of the soil, or simultaneous digging of holes for planting fruit trees using explosives, which is applicable both when planting a new orchard of fruit trees and when fertilizing and loosening the soil in older orchards. The essence lies in the fact that a combined charge consisting of industrial explosives and fertilizer is inserted into the holes in the soil.

Description

The present invention relates to a method for simultaneous fertilization and loosening of soil, or concurrent digging of fruit tree planting pits by means of explosives, which can be used both for planting a new orchard and for fertilizing and loosening the soil in older orchards.

Increasing fruit production is possible not only by expanding planting areas, but also by increasing yields of existing orchards. It is known that insufficient soil loosening prior to planting and poor tillage are the cause of poor growth, susceptibility to disease, increased susceptibility to frost and, consequently, unsatisfactory yields. Improving the living space of the root system of trees and shrubs and improving the soil is a crucial condition for success in fruit growing.

The planting of fruit trees is done by first loosening the plot to a depth of 0.5 to 0.7 m, then digging or drilling the usual holes. When a tree or shrub can unfold unhindered, the roots grow not only in width but also in depth to ensure the greatest possible living space. As most soils do not meet the requirements of fruit trees in their composition, or only partially comply, fertilization must be carried out.

In older orchards, deep soil loosening is sometimes necessary to improve the living conditions for the root system and to establish a balance between the crown and the root system.

It is necessary to replenish the exhausted elements. Due to soil loosening and fertilization, older trees and shrubs can again be encouraged to increase fertility and prolong their fertile years. As can be seen from the above, there are several operations in planting; deep plowing - digging holes (drilling) - fertilization - planting. U zmlazoyání old orchard: deep plowing - fertilization. Plowing can be done between rows, not between trees in a row.

The disadvantages of the conventional soil loosening method, digging of wells and fertilization are partially eliminated by the method according to the invention, which consists in drilling holes of 0.03 to 0.20 m in diameter and 0.5 to 1.2 m in depth, into which a combined charge consisting of 0.05 to 0.15 kg of industrial explosive and 0.05 to 1 kg of fertilizer is inserted and is detonated by detonator.

By using a combined explosive-fertilizer charge, a higher effect can be achieved over the above methods by simultaneously spreading the fertilizer in very fine form into the immediate vicinity of the root system, so that the roots of the tree are immediately acceptable. In such treated soil trees or shrubs develop faster, they are soon to be born and their yields are higher.

In order that the invention may be more fully understood, the following examples are provided.

Example 1

Planting a new orchard

The soil to be planted for the new orchard is analyzed for soil and the elements to be supplied and how much. Based on this, a combined fertilizer is prepared. Drilling is then carried out by 0 min using an earth drill mounted on the tractor. 40 mm, depth 0.5 to 1.0 m, depending on the type of soil. The wells are loaded with a combined charge, consisting of 0.05 to 0.15 kg of industrial explosives, adjusted by a detonator with firing pin and the necessary doses of fertilizer for a tree or shrub. The borehole is covered with soil and the fuse ignites. After the explosion, a crater is formed, the soil is loosened and fertilizer is dispersed into the surrounding soil. Trees or shrubs are then planted in such a well.

Example 2

Rejuvenating older orchards'

In a manner similar to Example 1, boreholes are carried out on the circumference of the tree crown, namely 3 to boreholes at equal distances from each other. In complete orchards, one row is advanced and one charge is placed between two trees and one on each side (3 per tree in total). The wells are drilled in 0 min. 40 mm deep 0.8 to 1.2 m, which is filled with a combined charge consisting of 0.05 to 0.15 kg explosives, adjusted by a detonator with firing pin and the required amount of combined fertilizer, whose composition is determined by soil analysis. The effect of the blasting is not limited to the perimeter of the blasting site, but creates small cracks far from the blasting site, which in turn allows better circulation of water, air and nutrients. The fertilizer is dispersed in a very fine form near the root system, and is immediately available to the tree. This results in rapid regeneration and increased yields of old trees.
