Description

Method for fertilizing walnut trees

Technical Field

The invention relates to the technical field of fertilization, in particular to a method for fertilizing walnut trees.

Background

The walnut is a food which is often eaten in daily life of people, can be eaten as raw or fried, can be used for extracting oil and preparing cakes, candies and the like, has very delicious and not only very good taste, but also has very high nutritional value and medicinal value and has very great beneficial effect on human bodies. During the growth process of walnut trees, various mineral nutrient elements need to be absorbed from soil to maintain the normal growth and development of the walnut trees, but most of the nutrients are provided by fertilization. As for the walnut trees growing for many years, the walnut trees are often luxuriant in branches and leaves, and the demand for fertilizers is great. At present, the fertilization method for perennial walnut trees is completed by a mode of manual ditching and deep burying, but the method is troublesome, high in manual strength and inaccurate in fertilization position, in order to solve the problem, the method adopted by the prior art is to drill holes in the bottom of the walnut trees towards the ground by using hard objects such as steel rods and the like, and then put fertilizers into the holes, but the operation has a defect that the roots of the walnut trees are damaged in the drilling process due to the fact that the end parts of the steel rods are sharp.

Disclosure of Invention

The invention aims to provide a method suitable for fertilizing walnut trees with deep root systems.

In order to achieve the purpose, the technical scheme of the invention is to provide a method for fertilizing walnut trees, which comprises the following steps:

step 1: preparing a walnut tree fertilizing device, wherein the device comprises a hole rotating mechanism and a material spreading mechanism, the hole rotating mechanism comprises a cylinder with the upper end closed and the lower end open, a pressure spring and a rotating head, and the cylinder comprises a top surface and a side wall; the material scattering mechanism comprises a material conveying pipe, a telescopic pipe and a hopper; the lower end of the cylinder is fixedly connected with the rotary head through a pressure spring, the rotary head consists of a rotary block, and the rotary block is arc-shaped; a cavity is arranged in the hole rotating mechanism in the whole body, and a telescopic cylinder fixedly connected with the top surface is arranged in the cavity; the feed delivery pipe is connected with a telescopic cylinder, and the telescopic length of the telescopic cylinder is greater than the length from the bottom end of the feed delivery pipe to the tip end of the rotary head; the hopper is arranged on the side wall, and the hopper is communicated with the conveying pipe through a telescopic pipe.

Step 2: moving the device under a walnut tree, applying downward pressure to the top surface of the hole turning mechanism to punch holes, compressing the pressure spring to the maximum extent, and driving the turning head to deviate by the deviation of the pressure spring when the turning head contacts with the root of the walnut tree;

and step 3: when the drilling depth reaches 0.5m, starting a telescopic cylinder, and enabling a telescopic rod conveying pipe of the cylinder to move downwards;

and 4, step 4: in the process of lifting the hole rotating mechanism upwards, the conveying pipe moves downwards to bounce off each rotating block, meanwhile, fertilizer is poured into the hopper, and the fertilizer enters the deep soil through the telescopic pipe and the conveying pipe.

The beneficial effect of this scheme is: the fertilizer can be conveyed to the deep part of the root system of the walnut tree after being punched by the fertilizing device, the fertilizing effect is good, and meanwhile, the problem that the root system is easily damaged by the rotary head in the punching process is effectively avoided; when the in-process that the mechanism of punching got into soil gradually, turn round probably with the contact of walnut tree root, because turn round be convex, root hardness is bigger than surrounding soil hardness simultaneously, at the in-process that continues to exert force and punch, the skew can take place for turning round to drive the pressure spring skew, so turn round can bypass the root, thereby avoid it to damage the walnut tree root.

Furthermore, a baffle is welded at the joint of the pressure spring and the lower end of the cylinder, and the angle formed by the baffle and the pressure spring is 5 degrees. The beneficial effect of this scheme is: the baffle can effectively avoid that the pressure spring deflection angle is too large, so that the dislocation between the rotary head and the side wall is too serious, and the drilling can not be continued.

Further, a handle is arranged at the upper end of the side wall. The beneficial effect of this scheme is: an operator can hold the handle to apply pressure downwards to punch holes, and operation is facilitated.

Further, the arc angle of the rotating block is 20 degrees. The beneficial effect of this scheme is: the arc angle is 20 degrees and is the preferred angle of this scheme, and most points of arcwall face contact can all effectively bypass the root under this angle with the root, avoids its damage.

Further, the upper wall and the side wall are integrally formed. The beneficial effect of this scheme is: the integrated into one piece makes things convenient for the casting, and the structure is more stable simultaneously.

When adopting above-mentioned technical scheme, can be through punching earlier, throw the root system depths with fertilizer again to reach better fertilization effect, effectually avoided the problem of punching in-process damage walnut tree root simultaneously.
