Description

Seed stem preparation and cutting equipment for cassava planting

Technical Field

The invention relates to the technical field of cassava planting, in particular to seed stem preparation and cutting equipment for cassava planting.

Background

The cassava, also called pachyrhizua angulatus, is one of three potato crops, is called starch king, is planted in many areas at present and is often used as industrial raw materials such as feed, starch, fuel ethanol and the like.

In the cassava planting process, healthy, strong and mature cassava stems are selected to serve as seed stems, after the seed stems are selected, original furrows in a field are dug deeply, the cassava stems are buried well, covered with grass or wool felt, prevented from freezing or turned home, placed in a shade house and planted in the spring of the next year.

The cassava seed placing method generally comprises three methods of straight insertion, oblique insertion and horizontal swinging, and each method has the advantages. The straight insertion is deep, drought resistance and wind resistance are strong, but the potatoes grow downwards and are difficult to pull out and dig. The germination rate of the oblique cutting is high, the potatoes grow obliquely when being gathered at one end, the potatoes are easy to harvest, but the wind resistance is poor. The two ends of the seed stem in the flat pendulum can bear potatoes, which is more wind-resistant and drought-resistant but has difficult seedling emergence. The location should be flexibly controlled according to the specific situation.

The cassava seed stem preparation and cutting equipment is generally carried out in steps (firstly, soil is thrown away, then, the cut and segmented cassava seed stems are placed, and finally, soil is backfilled), the operation steps are multiple, machines are frequently adjusted to ensure that the steps can be mutually matched to smoothly complete the cassava seed stem preparation and cutting, and the problems of complex operation and low working efficiency exist.
