Slash pine resin tapping method for total healing of tapping face

Abstract

The invention discloses a slash pine resin tapping method for total healing of a tapping face. The method comprises the following steps: opening a median gutter in the center or at one side of the tapping face during first tapping, wherein the length of the median gutter is about 20-25cm and the width is about 1.5-2cm; tapping in the same year, namely after the first tapping, tapping from top to bottom along a tree trunk in sequence at an interval of 4-6 days, and spraying an irritant agent once to the tapping face in a vaporific manner every 12 days till the end of the resin tapping period of the year; and performing subsequent tapping in the next year, namely tapping according to the tapping method of the past year. The method is characterized in that the cutting depth of the median gutter ensures that a cambium layer of the tree trunk cannot be cut wound, so that the cambium layer of the tree trunk can be reserved undamaged; the subsequent tapping in the next year is performed at a position 1-2cm below a side gutter of the tapping face formed in the past year to cut a new tapping face. The method has the advantages that a biological and chemical reagent is used for stimulating pines to ensure that the pines form and excrete more rosin, the rosin flowing time is prolonged, the yield of rosin is improved, and meanwhile the tapping face can be completely healed in 2-3 years.

Description

technical field [0001] The present invention relates to a kind of pine resin collection technology, especially relates to the technology of slash pine resin collection, specifically a kind that can make the resin collection cut surface of slash pine all heal within 2-3 years, improve the quality of resin collection trees The ability to resist windbreak, moth, and decay, enhance the nutrient transport capacity of trees, and then make the tree's fat production capacity and fat collection amount reach a high-efficiency dynamic balance method. Background technique [0002] The turpentine is processed to remove impurities, and the method of distillation is used to produce qualified rosin and turpentine products, which are important industrial raw materials. [0003] Pine resin is the nutrients absorbed by pine roots such as water and minerals are transported to the needles through the xylem sapwood, and then converted into sugars through the photosynthesis of the needles, and the...

Moreover, because its cut surface cannot be repaired better, there are many cases of resin pine tree malnutrition, cut surface corrosion, and damage by diseases and insect pests.
