A collection device and collection method for the mature cones of Fanjingshan fir

Abstract

The invention discloses a collection device and a collection method for the mature cones of fir from Mount Fanjing, comprising high branch shears and a bagging structure, wherein the high branch shears are the attachment structure of the bagging structure, and the bagging structure can be stretched by the extension of the high branch shears At the height, a bagging structure is arranged on the outside of the cutting head, bottom rod and extension rod of the high branch shears. When the extension rod of the high branch shears extends to the height with the cutting head, the L-shaped main rod of the bagging structure is used. Use the L-shaped sub-rod to open the edge of the metal mesh sleeve, so that the metal mesh sleeve is sleeved on the outside of the cone, and then pull the nylon tie to lock the metal mesh sleeve with the help of the movable knot of the fiber rope, and then use high branch shears to cut the nylon tie. With the tail, after the fir cones are fully ripe, the branches of the bagged cones are cut off with the help of high branch shears to harvest the fir cones, which realizes the complete collection of the mature fir cones in 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 the mature cones of Fanjingshan fir. Background technique [0002] Fanjingshan fir is a plant endemic to Fanjing Mountain in Tongren, Guizhou, China. It is a national first-class protected plant and an endangered plant. Fanjingshan fir is a rare species in the genus Fir. There are three reasons for it to become endangered: ①Due to narrow distribution, the natural population reproduction and renewal is poor; ②Fanjingshan fir has a very low seed setting rate and a lower seed germination rate, only 10% about. ③Because broad-leaved trees dominate the community, and the coverage between shrubs and herbs in the community has reached 95%, the surface moss grows densely, and there is a thick covering layer, so it is difficult for fir seeds to touch the soil. , the seedlings cannot grow into saplings under the pressure of the thi...

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.
