Embodiment Construction

[0013] A technique for rebuilding Torreya torreya bases by utilizing gaps, comprising three steps of gap selection, gap management and gap transplanting, characterized in that:

[0014] 1) select

[0015] In the torreya base, choose a forest gap with a large area, and the surrounding trees should be relatively low shrubs, which can help the growth of torreya and form an ecological balance in a small environment;

[0016] 2) management

[0017] Draw fixed-value grooves in the forest gap according to the contour line. The depth and width of the groove are both 2.5 m. The excavated deep soil covers 30-50 cm, and the row spacing for planting Chinese torreya should be controlled at about 5-6 m. During the first 5 years of planting Chinese torreya, the canopy density of the entire forest should be kept below 60% to ensure that the photosynthetic intensity in any period is uniform. Not less than 1600 lx, artificial pruning or transplanting can be adopted, and if necessary, add a sh...

Abstract

The invention discloses a Torreya grandis base reconstruction technology using gaps, in particular to reasonable rebuilding and utilization of gaps of a Torreya grandis base. The Torreya grandis base reconstruction technology using the gaps comprises the steps of selection of secondary forest gaps, gap management and subsequent transplantation of the gaps. The technology provides construction of the Torreya grandis base with a new explore mode, and the quality and yield of Torreya grandis can be maintained without affecting an original forest; by means of the technology, considerable ecological and economic benefits can be brought to the Torreya grandis base, and popularization is worthwhile for Torreya grandis planting industry.

Description

technical field [0001] The invention relates to the field of agricultural technology, and mainly relates to the technology of using forest gaps to rebuild a torreya base. Background technique [0002] 1. Illumination and moisture are important environmental factors affecting plant growth, and the size of the forest gap determines the light level and water content of the understory plants. At present, the evolution of the forest gap is mainly based on natural regeneration, but the base area of ​​Torreya torreya is relatively large , artificially changing the gap structure has a greater impact on the growth of Chinese torreya. [0003] 2. Under the background that the country vigorously advocates environmental protection, the traditional mountain refining method is no longer allowed. The construction of the Torreya base must be carried out in the forest, and the Torreya can still grow normally under a certain level of shading, so The growth of the torreya forest can be used t...
