Description

A young mulberry harvester

technical field

The invention relates to the field of agricultural machinery, in particular to a young mulberry harvester.

Background technique

Young mulberry has high nutritional value and strong regeneration ability, and is widely used in feed, medicine, industrial raw materials and other fields. At present, there are no high-efficiency harvesting platforms and harvesters for tender mulberry on the market. The tender mulberry mainly relies on manual and simple auxiliary machinery for harvesting. This operation mode cannot guarantee the same stubble height and incision after harvesting the tender mulberry. Flat and unbroken agronomic requirements, and affect the regrowth ability and yield of tender mulberry, seriously hinder the development of large-scale planting of tender mulberry.

To sum up, the current methods of harvesting young mulberry mulberry manually and with simple mechanical assistance cannot meet the agronomic requirements of consistent height of stubble and smooth cut without damage after harvesting young mulberry.
