The "V"-shaped groove cutting method is simple and easy to implement, and the side groove cutting surface can be updated at any time, but maple resin harvesting has its own particularity, and the above-mentioned "V"-shaped groove cutting method cannot be simply applied
Drilling cutting method is not easy to renew the cutting surface, resin and essential oil are easy to oxidize, deteriorate and volatilize, and the drilling damages the xylem deeply, hindering the growth of sweetgum tree and causing traumatic structural defects in the wood, reducing the physical and mechanical properties of the wood , which seriously affects the use of wood
In CN1195401C, a method for collecting tree exudates is disclosed, which is not fully applicable in the collection of maple resin, and further innovation and improvement are needed

Abstract
The invention discloses a method for collecting resin of sweetgum. The method is a V-shaped descent method, and comprises the following steps of: (1) selecting a sweetgum tree with the diameter at breast height of more than or equal to 20cm, and setting a cut face on a straight trunk which is exposed to the sun and has few burls; (2) setting a bark shaver face according to the selected cut face, wherein the bark shaver face is 4cm wider than the cut face, and the bark shaver face is 5 to 10cm longer than the cut face; (3) setting a medial groove in the center of the bark shaver face, and setting an apron at the tail end of the medial groove, and mounting a cup under the apron; and (4) cutting a first V-shaped lateral groove at the upper end of the medial groove, connecting the bottom of the V-shaped groove with the medial groove, cutting a new V-shaped lateral groove under the last V-shaped lateral groove every 5 to 7 days, wherein the included angle of the V-shaped lateral groove is 70 degrees, and the lateral groove is cut to the first or the second annual ring of the sweetgum tree. The method is particularly suitable for collecting the resin of the sweetgum trees; and after theV-shaped lateral grooves with the included angle of 70 degrees are adopted, and cut to the first or the second annual ring, the yield of the resin of sweetgum is greatly improved, and the growth of the sweetgum trees is not affected, so the method is a simple, convenient, quick and efficient method for collecting the resin of sweetgum.
Description
technical field [0001] The invention relates to a method for collecting tree secretions, in particular to a method for collecting maple gum, which is the oleoresin secreted by liquidambar gum. Background technique [0002] Chinese Sweetgum (Chinese Sweetgum, Liquidambar formosana Hance) is a kind of liquidambar formosana Hance, which belongs to Hamamelidaceae, and its aliases include maple, red maple, big-leaf maple, and triangular maple. There are five kinds of liquidambar plants, and there are 2 kinds and 1 variety in our country. Liquidambar is a deciduous tree, up to 40 m high, the bark is gray and smooth when young, and brown, rough and cracked when old. The leaves are alternate, the petiole is 3-7cm long; the stipules are linear and fall early. The leaves are palmately 3-lobed, and the leaves on seedlings and budding branches are mostly palmately 5-lobed, 6-12cm long. 8-15cm wide, apex acuminate, base heart-shaped, edges serrated. It often grows in the woods beside...
