Embodiment 1

[0054] Such as figure 1 , 2 , 3, a kind of method that realizes fat material double-purpose pine forest to collect fat for a long time, comprises the following steps:

[0055] (1) A 13-year-old Pinus massoniana with a diameter at breast height of 18.8 cm was selected in the Sanhe sub-field of Longlin Farm in Hengxian County, and the resin was harvested from the ground to the tree height of 1.7m by the method of descending double-side ditch and four-sided resin extraction, with a single angle of 30 The depth of the cutting groove is 0.3cm deep into the xylem, the step distance is 0.1cm, and it is harvested every two days; a middle groove is opened on the longitudinal center line of the cutting surface, 30cm long, 1.0cm wide, and 0.5cm deep, and a fat-receiving container is installed at the lower end. Select plastic cups and fix them with bamboo products. The fat harvesting load rate is 35%, the circumference of the cut surface is 20.7cm, and the fat harvesting is carried out c...

Embodiment 2

[0061] Such as figure 1 , 2 , 3, a kind of method that realizes fat material double-purpose pine forest to collect fat for a long time, comprises the following steps:

[0062](1) Select a 13-year-old Pinus massoniana with a diameter at breast height of 20.6cm in the Sanhe sub-field of Longlin Farm, Hengxian Town, and extract resin from the ground to the tree height of 1.8m by the method of descending double-side ditch and four-sided resin extraction, with a single angle of 30 The depth of the cutting groove is 0.3cm deep into the xylem, the step distance is 0.12cm, and it is harvested every two days; a middle groove is opened on the longitudinal center line of the cutting surface, 32cm long, 1.2cm wide, and 0.5cm deep, and a fat-receiving container is installed at the lower end. Select plastic film bags, use wooden products to fix, the fat harvesting load rate is 35%, the circumference of the cut surface is 22.6cm, the fat harvesting is continuous for 8 years, and the east fa...

Embodiment 3

[0068] Such as figure 1 , 2 , 3, a kind of method that realizes fat material double-purpose pine forest to collect fat for a long time, comprises the following steps:

[0069] (1) A 13-year-old Pinus massoniana with a diameter at breast height of 19.4cm was selected in the Sanhe subfield of Longlin Farm, Hengxian Town, and the resin was harvested from the ground to the tree height of 1.8m by the method of descending double-side ditch and four-sided resin extraction, with a single angle of 30 The cutting ditch is 0.3cm deep into the xylem, the step distance is 0.11cm, and it is harvested every two days; the middle ditch is opened on the longitudinal center line of the cutting surface, and the cutting length is 36cm, the width is 1.3cm, and the depth is 0.5cm. The fat container is made of plastic cups, fixed with bamboo products, the fat harvesting load rate is 35%, the circumference of the cut surface is 21.3cm, the fat harvesting is continuous for 8 years, and the east face f...

Abstract

The invention discloses a method for realizing long-term resin tapping of a pine forest with dual purposes of resin and timbers. The method comprises the step of tapping resin through adoption of a resin tapping mode, wherein in the resin tapping mode, resin tapping is carried out from four surfaces of the east, west, south and north, and the tapping height is controlled strictly. A nutrition zoneof 10 cm or above is retained among the four tapping surfaces, little effects are generated on the growth in volume of pine trees on the premise of ensuring continuous resin tapping for 32 years, andoutput of timbers and pine resin can be optimized; and the goals of sustainable utilization and sustainable development of forests can be achieved through the pine forest with dual purposes of resinand timbers, and useful complements are provided for poverty elimination of forest farmers and ecological construction in mountainous areas.

Description

【Technical field】 [0001] The invention belongs to the technical field of pine tree planting, and in particular relates to a method for realizing long-term resin harvesting in pine forests with both resin and resin materials. 【Background technique】 [0002] Masson pine is an important native fast-growing timber and resin species in southern my country, which grows rapidly and has a wide range of uses. Guangxi is the central production area of ​​masson pine, rich in genetic resources, and the effect of genetic improvement is in the forefront of the country. Guangxi is the most important producing area of ​​rosin and rosin in the country, and the output of rosin and rosin has been in the forefront of the country for many years. Because the dual-purpose forests only harvest resin and do not cut down trees, which meets the needs of ecological construction, the area of ​​resin mining forests in southern my country increases year by year. Forest farmers take short-term benefits as...
