Problems solved by technology

It has been planted on a large scale in the red soil area in southern my country. Due to its drought resistance and barrenness tolerance, most of the artificial pure forests are planted in Class III and IV forest lands, so that the masson pine pure forest has a single tree species structure, lack of shrub and grass layers, and slow litter accumulation. , low biodiversity, declining soil fertility, deterioration of the ecological environment, and serious damage from pine scales and pine nematodes

Embodiment 1

[0042] Implementation location: Dongshan Park, Jingdong Village, Jingcheng Street, Zhangping City, Fujian Province, with an area of ​​20 mu, and the site type is Class III. The altitude is 205m, the terrain is relatively gentle, and the slope is below 20°. Afforestation was carried out in 1990, with a plantation density of 167 trees / mu, and a plant-to-row spacing of 2m×2m. Cutting once in 2005, with 80 remaining plants.

[0043] (1) Thinning: The second thinning was carried out in 2013. After thinning, the canopy density of the remaining stand was 0.4, and the number of remaining trees was 30 trees / mu.

[0044] (2) Digging holes: Under the canopy of Masson pine after thinning, randomly dig holes along the contour line according to the reserved density. The density is 80 plants / mu. Apply 5 kg of organic fertilizer to each hole.

[0045] (3) Planting: Select the rainy day in January to implant the annual Sapindus and the biennial Golden Camellia container seedlings into the ...

Abstract

The invention relates to a method for transforming different-age compound layers of pinus massoniana and planting camellia nitidissima under canopy. The method comprises following steps: selecting forest land, thinning, reducing canopy density, land preparing, interplanting broad-leaved trees and camellia nitidissima, planting, tending, water and fertilizer management, pruning, disease and insectpest control, etc. The invention has innovations in forest stand transformation, soil improvement, disease and insect pest control, camellia nitidissima planting and management. The space of pinus massoniana is fully utilized; deciduous broad-leaved trees and evergreen camellia nitidissima are planted according to a certain proportion; biological characteristics of the mix tree species are taken into consideration, realizing the mutual promotion of multiple tree species, so that the growth of the forest tree can reach the near-natural effect so that that high-efficient utilization of the forest land resource can be realized, and the planting way of the rare plant camellia nitidissima can be enlarged. The method is a kind of imitation wild planting method, which can improve the yield and benefit of woodland per unit area, and can also achieve the goal of long-term near-natural management of eco-economic mixed forest of Pinus massoniana, and obviously improve the efficiency of artificialafforestation of mixed forest.

Description

technical field [0001] The invention belongs to the field of tree cultivation, and in particular relates to a method for transforming a pure masson pine forest after canopy closure into a multi-layered forest of different ages and planting golden camellia under the canopy. Background technique [0002] Masson pine (Pinus massoniana Lamb.) is a tree in the family Pinaceae, with a height of 45m and a diameter at breast height of 1.5m; the bark is reddish-brown, the branches are flat or oblique, the crown is wide tower-shaped or umbrella-shaped, and the branches grow 1-3 times a year. Round, winter buds ovoid-cylindrical or cylindrical, needles, soft, slightly twisted, with stomatal lines on both sides, fine serrations on edges; leaf sheaths persistent. Male cones are light reddish brown, cylindrical, clustered in the bract axils of the lower part of new branches, spike-shaped, female cones are clustered near the top of new branches, lavender, long oval seeds, flowering in Apri...
