Abstract

The invention discloses a pinus yunnanensis bark beetle-resisting mingled forest mode rapid screening method, and relates to a combined method for intergrowth of various forests. The method comprises the following steps of: selecting a mingled proportion by using a Y-shaped olfactometer, setting a replacement corresponding set of pinus yunnanensis needles and non-host leaves on a reaction arm (n is not greater than 10) of the Y-shaped olfactometer, and then selecting different mingled modes by using branch frames, wherein Cupressus torulosa, camphor trees and Cyclobalanopsis glaucoides are used as the non-host leaves and branches for testing. As a result, the inter-plant mingled forest culture of the pinus yunnanensis and the non-host leaves is better, and the non-host leaves appropriately account for 30%-50%. The method has the advantage of less material consumption and can rapidly and conveniently forecast the disease and inset-resisting mingled forest modes.

Description

technical field The invention belongs to forestry protection, and relates to a combined method for the symbiosis of various trees. Background technique Pine yunnanensis is the main tree species in Yunnan and Sichuan, and it is facing the serious threat of the pine beetle. Large areas of pure forests are killed by the beetle. The main control measures include cleaning the beetle wood, pesticide control, biological control, and bark beetle. Aggregate pheromones for lure and silvicultural measures. Mixed forest is one of the important ecological control technologies generally recognized at home and abroad. Compared with artificial pure forest, mixed forest has incomparable advantages in terms of forest ecosystem stability, forest soil fertility improvement, water and soil conservation, restoration of degraded ecosystem, forest disease and insect pest control, etc. Advantage. However, most studies on mixed forest models are not designed for pest resistance, but are based on th...
