Collection device and collection method for ripened cones of abies of Fanjing mountain

Abstract

The invention discloses a collection device and collection method for ripened cones of abies of Fanjing mountain. The collection device comprises high branch scissors and a bagging structure, whereinthe high branch scissors are of an attachment structure of the bagging structure; the bagging structure can stretch to a high place through stretching of the high branch scissors; and the bagging structure is arranged at the outer sides of a shearing head of the high branch scissors, a bottom rod and an extension rod. When the extension rod of the high branch scissors drives the shearing head to extend to the high place, a closing edge of a metal net cover is opened by virtue of an L-shaped main rod and an L-shaped secondary rod of the bagging structure, and the metal net cover sleeves the outer side of one cone; a nylon cable tie is pulled to lock the metal net cover by virtue of a movable knot of a fiber rope; the tail part of the nylon cable tie is sheared off by using the high branch scissors; and an inserted branch of the bagged cone is sheared off by the high branch scissors to harvest the cones of the abies after the cones of the abies are ripened thoroughly, thereby achieving complete collection of the ripened cones of the abies of the Fanjing mountain.

Description

technical field [0001] The invention relates to the technical field of picking machinery, in particular to a collecting device and a collecting method for mature cones of Abies Fanjingshan. Background technique [0002] Fanjingshan fir is a unique plant in Tongren Fanjingshan, Guizhou, China. It is a national first-class protected plant and is also an endangered plant. Abies Fanjingshan is a rare species in the genus Abies, and there are three reasons why it is endangered: ① Due to the narrow distribution, the natural population reproduction and renewal are poor; ② The seed setting rate of Abies Fanjingshan is very low, and the seed germination rate is lower, only 10% about. ③Because broad-leaved trees dominate the community, and the coverage between shrubs and herbaceous layers in the community has reached 95%, moss on the surface grows densely and has a thick covering layer, so it is difficult for fir seeds to touch the soil. , Seedlings are also unable to grow into sapl...

AI Technical Summary

Problems solved by technology

[0003] The mature cones of the existing Fanjingshan fir are picked under the conventional tree with ordinary high-branch shears, which may easily cause the mature cones to scatter seeds due to shaking (or scatter seeds due to collisions during the falling process of the cones), and also cause the cones to fall to the ground. Afterwards, it is difficult to find and seriously affect the efficiency of seed collection. In addition, although the collection of immature cones in advance by conventional under-tree picking methods can reduce seed scattering, the germination ability of collected immature cone seeds will be greatly reduced.
