Description

A device for cutting the stellera chamaejasme with roots in grassland

Technical Field

The invention relates to the technical field of mowing devices, in particular to a device for mowing Stellera chamaejasme with roots in grasslands.

Background technique

Stellera chamaejasme belongs to the genus Stellera of the family Thymelaeaceae. It is a perennial herb with a thick root system. It is commonly known as heartbroken grass, steamed bun flower, red match head, and stuffy flower red wolfsbane. It has a strong root system and strong ability to adapt to climate. It is a poisonous plant that causes serious harm to natural grasslands in northern my country. Since the whole bead of Stellera chamaejasme is poisonous, its roots are the most toxic. The main toxic components are diester diterpene alkaloids such as aconitine, mesoaconitine and mesaconitine. The tubers after the branches and leaves wither are highly toxic, followed by the stems and leaves. The allelopathic substances in its roots can significantly inhibit the growth of excellent forage roots, leading to the deterioration of the grassland ecological environment. When Stellera chamaejasme occurs on a large area on a flat grassland, a harvester can be used to mow it. When Stellera chamaejasme grows on hillside grasslands and is scattered on the grassland, most of them are harvested and excavated by hand because large equipment is not easy to carry.

However, although manual excavation of Stellera chamaejasme is convenient, the excavation efficiency is low. A large excavation area is required during the excavation process, which is very destructive to the grassland and has low soil loosening efficiency. When the excavation depth is not enough, the roots of Stellera chamaejasme cannot be completely removed. The roots of Stellera chamaejasme are easily damaged during the excavation process, which is not conducive to its complete removal and affects the management efficiency. Therefore, a grassland Stellera chamaejasme root mowing device is needed to solve the above problems.
