Embodiment 1

[0028] The implementation site is located on the northern slope of Taibai Mountain, Tiantong Forest Farm, Yinzhou District, Ningbo, Zhejiang Province, with an altitude of 530m, a slope facing north, a slope of 25°, red soil, soil thickness ≤ 90cm, loam quality, and an area of ​​320 mu.

[0029] The forest history of the implementation site is before 1959. The land is shrubs and barren hills. In 1965, the forest farm built a black pine artificial forest with an initial planting density of 420 trees. Frequent outbreaks and low protection efficiency. It is expected that the growth of black pine shelterbelts will not reach the cultivation target to realize the forest stand. In 1978, pine seedlings were replanted under the canopy of the black pine forest. In 1991, black pine trees withered and died in large areas.

Abstract

The invention discloses a method for transforming degraded lodgepole pines into a high-quality pseudolarix protection forest. For the situations of lodgepole pines in mountainous regions at a higher altitude that the growth is slow, plant diseases and insect pests occur frequently, the protection effect is poor and the stand regeneration is difficult, through the technical measures of sample-plotsurvey, determination of restoration tree varieties, sanitation felling and land preparation, reinforcement planting of target tree varieties, young forest tending, lighting cutting, tending felling,cultivation of target tree varieties and stand management, the stand structure, species composition and stand health condition are improved, the survival and growth of trees are obviously promoted, and the forest wood quality is improved. Compared with the prior art, the method for transforming the degraded lodgepole pines into the high-quality pseudolarix protection forest has the advantages thatthe construction is easy, the restoration is fast, the productivity is high, the protection effect is good, the operation is easy, the healthy and stable development and sustainable use of the forestcan be effectively promoted, and the method can be used for the ecological restoration reconstruction of degraded protection forests in the mountainous regions at the higher altitude.

Description

technical field [0001] The invention relates to a transformation technology of a degraded shelter forest, and specifically introduces a method for transforming a degraded black pine forest into a high-quality pine forest. Background technique [0002] Due to the influence of special geographical and environmental conditions, there are many high-altitude and difficult-to-afforestation areas within the coastal mountain range. These mountainous areas with an altitude of 400-700m have complex climate conditions, fragile ecological environment, frequent ecological disasters, and difficulties in afforestation. How to keep the protective benefits of existing shelterbelts uninterrupted has become a difficult point in the management of coastal shelterbelts. In order to strengthen the construction of protective forests, a large area of ​​black pine or masson pine forests were artificially built in the 1960s. However, due to the damage of pine nematodes and ineffective tending measures...
