Embodiment 1

[0046] Such as figure 1 , 2 , 3, a method for sustainable management of pine wood dual-purpose forests, comprising the following steps:

[0047] (1) Select a 10-year-old Masson pine with a DBH of 16.5 cm in the log storage yard of Dawu Subfield, Longlin Farm, Hengxian Town, and collect resin on both sides of the tree from the ground to the tree height of 2m from the ground to the height of 2m. Fat harvesting method, with a single angle of 30 degrees, cutting grooves deep into xylem 0.3cm, step distance 0.1cm, harvesting once a day; open a middle groove on the longitudinal center line of the cutting surface, cutting 30cm long, 1.0cm wide, and 0.5cm deep , Install a fat-receiving container at the lower end of the middle ditch. The fat-receiving container is made of a plastic cup and fixed with bamboo products. The fat harvesting load rate is 45%, and the circumference of the cut surface is 23.3cm. The fat harvesting has been carried out continuously for 8 years, and the fat har...

Embodiment 2

[0051] Such as figure 1 , 2 , 3, a method for sustainable management of pine wood dual-purpose forests, comprising the following steps:

[0052] (1) Select a 10-year-old Masson pine with a DBH of 16.7cm in the log storage yard of Dawu Subfield, Longlin Farm, Hengxian Town. On the upslope of the tree, harvest from both sides of the descending double-side ditch from the ground to the tree height of 1.9m. Fat harvesting method, with a single angle of 30 degrees, cutting grooves deep into xylem 0.3cm, step distance 0.1cm, harvesting once a day; open a middle groove on the longitudinal center line of the cutting surface, cutting length 32cm, width 1.2cm, depth 0.5 cm, install a fat-receiving container at the lower end of the middle ditch, use a plastic film bag for the fat-receiving container, and fix it with wooden products. fat;

[0053] (2) Select the downhill surface of the tree, leave 11cm and 10cm nutrient zones respectively from the uphill cutting surface, and extract res...

Embodiment 3

[0056] Such as figure 1 , 2 , 3, a method for sustainable management of pine wood dual-purpose forests, comprising the following steps:

[0057] (1) Choose 10-year-old Masson pine with a DBH of 17.3 cm in the log storage yard of Dawu Subfield, Longlin Farm, Hengxian Town. On the upper slope of the tree, from the ground to the tree height of 2.1 m, it is collected on both sides of the descending double-side ditch. Fat mining method, with a single angle of 30 degrees, cutting grooves deep into xylem 0.3cm, step distance 0.1cm, harvesting once a day; open a middle groove on the longitudinal center line of the cutting surface, cutting length 36cm, width 1.3cm, depth 0.5 cm, install a fat-receiving container at the lower end of the middle ditch, use a plastic cup for the fat-receiving container, and use bamboo products to fix it, the fat harvesting load rate is 45%, the circumference of the cut surface is 24.4cm, the fat harvesting has been continuous for 8 years, and the fat harv...

Abstract

The invention discloses a pine tree and rosin material dual-purpose forest sustainable management method. The method comprises the following steps of (1) selecting an upslope surface of a pine tree, collecting rosin according to a descending double-side ditch two-side rosin collecting method, forming a middle ditch in the longitudinal center line of a cutting surface, installing a rosin receivingcontainer at the lower end of the middle ditch, and completing upslope rosin collection; (2) selecting a downslope surface of the tree, collecting the rosin according to the descending double-side ditch two-side rosin collecting method, forming a middle ditch in the longitudinal center line of the cutting surface, installing a grease receiving container at the lower end of the middle ditch, and completing the downslope rosin collection of the tree; and (3) calculating the total rosin collection area, felling and selling the pine trees subjected to uphill and downhill two-side rosin collection,counting the total output value of the sum of the rosin income and the wood income, and calculating the economic benefit. The method provided by the invention is applicable to medium-and-long-term pine tree rosin collection, and solves the problems of backwardness, poor forest quality, slow growth of forest trees, low rosin yield per unit area, shortened cutting life, low economic benefit and thelike of the traditional rosin collection technology.

Description

【Technical field】 [0001] The invention belongs to the technical field of pine tree planting, and in particular relates to a sustainable management method for dual-purpose forests of pine resin materials. 【Background technique】 [0002] Masson pine grows rapidly and has a wide range of uses. It is an important native tree species in southern my country, supporting the development of Guangxi's "papermaking and wood deep processing" industry worth 100 billion yuan and its characteristic advantage "pine resin industry". Guangxi is the central production area of ​​masson pine, rich in genetic resources, and has achieved remarkable results in genetic improvement. Guangxi is the most important producer of rosin and rosin in the country. The output of rosin and rosin has ranked first in the country for many years. At the same time, rosin can provide important economic income other than timber, and it is the most traditional source of bulk forest products for southern plantations. W...
