Method for collecting latex from old rubber trees

Abstract

The invention discloses a novel method for collecting latex from old rubber trees. Specifically, the method comprises the steps of drilling a drill hole (2) with the diameter being about 0.8 cm and the depth being 15 cm on a tree head (1), and implanting a set of new plastic tube device in the drill hole (2); and the device is characterized by comprising a thin plastic tube (3) with the length being about 20 cm and the inner diameter being about 0.15 cm; the outer tail end of the thin plastic tube is sleeved with a conical tubular plug (4) with the length being about 8 cm and the diameter in the maximum position being about 1 cm; two handles (5) are formed on the plug; a liquid inlet (6) with the diameter being about 0.15 cm and a liquid outlet (7) with the diameter being about 0.15 cm are formed at the outer tail end of the plug; the thin plastic tube (3) and the liquid inlet (6) form a liquid inlet pipeline; excess liquid in the drill hole (2) can be discharged from the liquid outlet (7); and a plastic cover (8) covers the outer tail end of the plastic tube device. A certain amount of ethephon preparation is injected through the plastic tube device, so as to stimulate a rubber tree, latex is collected through methods, such as short line rubber tapping, low-frequency rubber tapping, acupuncture rubber collection and the like as required, and the collection position can be any position of a trunk bast. According to the method, the purposes of increasing in yield, improving efficiency, reducing the bark consumption and the like are achieved.

Description

technical field [0001] The present invention relates to the technical field of rubber tree rubber harvesting, in particular, relates to the application in old rubber trees (more than 25 years old), a method of drilling holes in the tree head and injecting ethephon preparation to stimulate the rubber tree, adopting short-line rubber tapping and low-frequency rubber tapping , acupuncture and other methods to collect latex to achieve the purpose of increasing production, improving efficiency, and reducing bark consumption. Background technique [0002] At present, the total area of ​​natural rubber cultivation in China is about 1 million hectares, ranking fourth in the world. Among them, there are about 330,000 hectares of old rubber trees over 25 years old, accounting for about 1 / 3 of the total area and 2% of the total area of ​​cut trees. / 5. The cultivation of natural rubber is a labor-intensive production method, and labor costs account for more than 60% of the total produ...

Problems solved by technology

However, although the method has been continuously improved for more than 20 years (see Chinese Patent Authorized Publication No. CN 2606521Y; CN 200973290Y; CN 202276688U), an indisputable fact is: due to the complicated installation of the method, high cost, and certain influence on the bark Injury and other reasons, so far, in China, it has not been widely used in production
