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.
