Description
Technical field
The present invention relates to bamboo grows and adopt the glue technical field, specifically, relate to and use in aged bamboo grows (more than 25 years), a kind ofly stimulate bamboo grows in tree head boring and injection ethrel preparation, adopt the methods collection latex such as short line rubber tapping, low frequency rubber tapping, Puncture tapping, to reach volume increase, to raise the efficiency, reduce the method for the purposes such as bark consumption.
Background technology
At present, about 1,000,000 hectares of the Natural Rubber Industry in China cultivation gross area occupies the 4th in the world, and wherein the age of tree is in the aged bamboo grows more than 25 years about 330,000 hectares, accounts for 1/3 of the gross area, accounts for to open and cuts 2/5 of the tree gross area.The cultivation of natural rubber belongs to the labour-intensive mode of production, and labor cost accounts for more than 60% of total cost of production, and wherein adopting glue production is the key link that the natural rubber cultivation is produced, and accounts for more than 75% of workforce cost.Along with improving constantly of wage level, labor cost has growing trend.Adopt the glue technology and be the key technology in rubber production, workman's pre-job training needs a large amount of time and expense.Reducing labor cost, particularly reduce the labor cost of adopting the glue link, is the key that the natural rubber cultivation benefit improves.
Traditional glue mode of adopting is to cut everyday or cut once in two days, and labor productivity is very low., after secant spreads the ethrel tapping with stimulus, can cut once in three days, four days from the invention seventies in last century, improve labor productivity.But, use the ethrel preparation at adjacent bamboo grows secant position, secant and near bark structure following variation can occur: the outer latex dust Mortality of bark, cause the binder removal line to narrow down, the screen casing layer thickness reduces owing to outer screen destroys, and is getting close to formation layer place's formation lithocyte, and tannin cell increases, bark occurs fertile swollen, and wound is difficult for healing.Therefore, use ethrel and promoted bark local old and feeble, excessively use ethrel even can cause the appearance of gum dead skin symptom.Owing to usage amount is restricted, ethrel was smeared stimulation five days or the longer time is cut the tapping system of a cutter in never spread use of production.Same reason is smeared ethrel by increasing and is realized that the effect of short line rubber tapping is also very limited.If but to further improve glue worker's labor productivity, the method that existing secant is smeared the ethrel tapping with stimulus just is faced with the limit that is difficult to cross over.
Since early 1990s Malaysian invention gas thorn is adopted gluing method (seeing Chinese patent mandate publication number CN 1069164A), owing to stimulate bark with the direct high strength of ethylene gas, the Length Ratio tradition rubber tapping method of secant is wanted much shorter, workman's speed of tapping rubber improves (can bring up to 1000 strains from cutting for each person every day 350 strains in theory) greatly, to the also greatly reduction of requirement of rubber tapping technology.But, (see Chinese patent mandate publication number CN 2606521Y although over more than 20 year the method constantly improved; CN 200973290Y; CN 202276688U), a undisputable fact is: owing to the method install complicated, cost is higher, bark is had certain reasons such as injury, up to the present, in China, also not on producing spread use.
Tree injection dispenser (fertilizer) technology is a comparatively ripe technology.Interior absorption medicine, mineral matter, plant growth regulator etc. inject in the tree body by self-flowing type or high pressure, vertically transportation can occur with the moisture movement of tree body in them, horizontal diffusion occurs in transportation simultaneously, can either be from root to top tip transport of blades, spread, retain and occur metabolism, some medicine can be transported to root through phloem sieve tube with descending liquid again simultaneously, or directly shifts, transmits, spreads, retains and occur metabolism from xylem to phloem.After ethrel preparation (the pH value is below 3) infiltrates through bamboo grows xylem (the pH value of resin is about 7), can decompose and discharge ethylene gas, bamboo grows is produced spread effect.Gas stings little segmentation method application attestation on producing: bamboo grows can be restrained oneself heavy dose of ethylene gas to be stimulated.The bamboo grows xylem has substantially exceeded phloem to the ethrel drug resistance, for the ethrel of heavy dose adopt that use in the glue production provides may.
