Description

A subsoiling machine suitable for brick red loam banana field

technical field

The utility model relates to a subsoiling machine, in particular to a subsoiling machine suitable for brick red loam banana fields, belonging to the technical field of agricultural machinery.

Background technique

Banana is the world's largest fruit in terms of trade volume and fresh fruit consumption. It is positioned by the United Nations Food and Agriculture Organization as the fourth largest food crop in developing countries after rice, wheat and corn. Today, the banana industry has become the mainstay of agriculture in the South subtropical region of China. The sex industry plays an important role in the economic and rural social development of hotspots.

The short-cycle banana planting method combined with the traditional banana field ploughing and rotary tillage has greatly increased the number of operations of agricultural machinery and tools. In the long-term, the soil under the ploughing layer of the banana field has been continuously compacted and formed a plow bottom, which in turn reduces the soil surface roughness. It is difficult for rainwater to quickly penetrate into the soil to form surface runoff and take away a large amount of surface soil and organic matter, which affects the growth of banana trees and the yield and quality of bananas. The banana fields in the hot zone are mainly brick red loam, which is sticky and heavy, and the soil layer is deep. In the hot and rainy environment, the soil is prone to brick red loam, resulting in high resistance and low efficiency in the current subsoiling operation of banana fields.

As one of the key technologies of conservation tillage, subsoiling uses subsoiling shovel to loosen the soil and break the bottom of the plow, which can effectively improve the soil structure and improve the ability of soil water storage and drought resistance.
