Description

A banana shovel type subsoiler

technical field

The invention belongs to the technical field of agricultural machinery, and in particular relates to a banana shovel type subsoiler.

Background technique

For a long time, the plowing operation of banana plantations in my country still uses the traditional plowing and rotary plowing methods, which not only causes the plow layer to be compacted under the plowing layer of the soil, but also leads to a decrease in the surface roughness of the soil, and rainwater cannot quickly penetrate into the soil to form a plow layer. The runoff takes away a large amount of soil and organic matter, seriously affecting the growth of banana trees and the yield and quality of bananas.

Subsoiling and plowing is a new type of soil cultivation method. If the subsoiling technology can be used to loosen the soil of the banana field, break the plow layer formed by plowing for many years, and deepen the plow layer, not only can adjust the three-phase ratio of the banana field soil, Optimize the soil structure, reduce soil water erosion, and improve the water storage and moisture conservation capacity of the banana field and the ability to resist drought and flood. And to a certain extent, it can improve the yield of bananas, root growth and lodging resistance of banana trees.

Therefore, it is of great significance to develop a subsoiling weeding machine adapted to my country's banana plantations with simple structure, small working resistance, and small soil disturbance, which is used in conjunction with tractors, to promote agricultural development in tropical crop areas.
