Ultralow-frequency resin tapping method

Abstract

The invention discloses an ultralow-frequency resin tapping method. The method includes the following steps that a shaved face is made in advance; a middle groove is formed; a resin guiding device and a resin receiving device are installed, namely, the resin guiding device and a resin receiving bag are installed at the tail end of the middle groove; the top of the middle groove is cut towards the left and right sides in an upward inclined mode to form a first pair of cut grooves respectively; afterwards, every 12-20 days, a trunk continues to be cut from top to bottom in sequence from the lower edges of the tapping cut grooves formed last time; a resin accelerator is sprayed on cutting faces; the part between the tops of the first pair of cut grooves and the upper portion of the resin receiving bag is covered with a film in a closed mode. The method has the advantages that the tapping frequency is reduced, the tapping period is prolonged, and the resin tapping time limit of each pine reaches above 30 years; meanwhile, the quality of resin is improved, the impurity removal process is omitted for subsequent processing of resin, and therefore the subsequent processing cost is lowered.

Description

technical field [0001] The invention relates to a turpentine collection technology, in particular to a resin collection technology that prolongs the harvesting interval and improves the quality of the resin, which we call an ultra-low frequency resin collection method. Background technique [0002] First of all, it needs to be explained that the so-called "ultra-low frequency" refers to the time interval between the upper and lower cutting trenches, which is the number of times pine trees are harvested and cut within a year. That is to say, the shorter the harvesting interval, the higher the harvesting frequency, and the longer the time interval, the lower the harvesting frequency. Generally speaking, the time interval of traditional fat harvesting technology is 1 to 2 days, which is usually called high-frequency fat harvesting, and the time interval of more than 4 days is usually called low-frequency fat harvesting. It can be called ultra-low frequency fat extraction. ...

Simultaneously, because its cutting surface and cutting ditch are exposed outside for a long time, impurity such as coarse dander, leaf, sandstorm, moth, insect of pine tree enters in the grease acceptor with flowing rosin, seriously pollutes the quality of the turpentine that collects, makes Subsequent processing of rosin has to carry out impurity removal treatment (and some impurities are difficult to remove, thereby affecting the quality of subsequent processing products), thus increasing the cost of subsequent processing
