Good lun plantations and the promotion of strong growth in many proved t: red-orange in the first five years after planting must be carried out after the first transmission interval t 3 to 5 years to conduct four translucent,[link widoczny dla zalogowanych], except in the light even when to retain some responsibility for hardwood outer needle. Other broad-leaved and irrigation technique to be cutting pine growth when the gland ‰ to 2O years later, will be carried out after the first one helped nurture the growth of every 5 ~ 1o years and then with secondary growth tending t the growth of population work research and development at different stages, each hectare of number of trees for the 21 ~ 3O years old as 1200, 31 ~ 4o years old when 800, 41 to 50 years old when 500 in the growth rearing process, retention of wood to the single- strains of scientific management, such as the timely repair technology, timely fertilization, pollination,[link widoczny dla zalogowanych], spraying hormones to accelerate tree growth and early fruit. according to the inherent assets, household contracting, two-way by security,[link widoczny dla zalogowanych], with a valid return has been to foster two-way operation area, operating period,[link widoczny dla zalogowanych], the contractor responsibility, care harvest, and households to benefit from the implementation, do not sweep blue, without prejudice to the retention of wood.

Third, two-way pine plantation cultivation. From understanding to implementation only in recent years, Mudanjiang Forestry forest during the two-way education process Suiyang indicated: two-way one-way nurturing and fostering the economic ratio of 2:1. T listed in the following table with the one-way two-way comparative effectiveness of training hectares Unit: million of future economic construction as the fat feed and increasing the living standards of people, two-way training content of the new forestry production will bring to the enterprise to report high economic benefits.
