Single-hole glue collection method with low skin consumption and dead skin prevention
A technology for picking rubber and dead skin, which is applied in agriculture, forestry, application, etc. It can solve the problems of increased skin consumption, drying of the rubber harvesting surface, and affecting the economic life of rubber trees, so as to reduce skin consumption, prevent dead skin, and improve The effect of rubber mining labor efficiency

Embodiment 1
[0033] Example 1. A single-hole rubber mining method that consumes less skin and prevents dead skin, such as Figure 1-2 shown, including the following steps:
[0034] Step A. Select the trunk of the rubber tree with complete and full raw skin as the rubber harvesting planning surface, shallowly open the upper water line, lower water line and half of the spiral secant on the rubber harvesting planning surface, and above and below the newly opened spiral secant The rubber picking is called opening line according to the slope of the secant line of the positive knife and the slope of the secant line of the negative knife. The slope of the secant line of the positive knife is 25-30 degrees, and the slope of the secant line of the negative knife is 40-45 degrees. Helically arranged in the direction of male secant and / or female secant;
[0035] Step B. Arrange single-hole rubber sampling points on the rubber mining planning surface, and arrange about 10 points along the positive k...
Embodiment 2
[0046] Example 2. When a single-hole rubber mining method that consumes less skin and prevents dead skin is applied, the rubber mining steps include:
[0047] Table 2 The design of the rubber mining method of implementing the undercut knife on the rubber mining surface
[0048]
[0049] Note: In this example, the knife-cut rubber harvesting frequency at the end of the year is used every three days, and other rubber tapping frequencies can also be used to tap rubber, or the bark can be directly shoveled off. P6 means every six days, P5 means every five days, P4 means every four days, and P3 means every three days.
[0050] The single-hole rubber mining method using the negative knife cutting line, according to the different rubber mining frequencies, the drilling time and tapping time are different. The rubber mining started in May, and the month of six-day one-needle single-hole rubber mining is from May to October, and the rubber can be harvested 30 times in 5 months. Ac...
Embodiment 3
[0056] Example 3. A single-hole rubber mining method with less skin consumption and anti-dead skin is compared with the conventional tapping glue outflow, rain flushing, and rain stop cutting times, as shown in Table 4.
[0057] Table 4 Statistics on the number of conventional 1 / 2 cutting glue outflow, rain flushing glue, and stop cutting due to rain
[0058]
[0059] Note: CK refers to the conventional one-half rubber cutting (knife cutting control) method.
[0060] Conventional use of half the length of the cutting line for cutting glue. In one cutting year, due to the outflow of glue, the number of rain flushing and the number of cutting knives stopped due to rain is about 17 times, accounting for 28.3% of the entire cutting year, which not only causes waste of glue, but also greatly The labor productivity of picking rubber is reduced, which is unfavorable for rubber production.
