Method for improving land utilization rate of macadamia nut forest

Abstract

The invention provides a method for improving the land utilization rate of a macadamia nut forest, and belongs to the technical field of under-forest cultivation. The method comprises the following steps: planting any one or more of Lipu taro, amorphophallus bulbifer, rice beans or desmodium leucocarpum in a macadamia nut forest; the forest stand canopy density of the macadamia nut forest is 0.1 or below; the distance between the Lipu taro, the konjak bulbifer, the rice beans or the desmodium banquetum and the macadamia nut forest is 0.7 m or above. The method can effectively improve the growth amount and yield of the forest, shorten the operating cycle of the forest land, effectively improve the continuous operating and comprehensive operating income of the forest land, effectively solve the contradiction between water, fertilizer and light between the forest and crops, and improve the physical and chemical properties of the forest land soil.

Description

A method to improve land use efficiency of macadamia nut forest technical field The invention belongs to technical field of understory cultivation, relate in particular to a kind of method improving macadamia nut forest land utilization rate. Law. Background technique [0002] Economic forest can realize the combination of ecological benefit, economic benefit and social benefit. The characteristic economic forest is the forest in Yunnan Province. It is an important part of the industry and an important source of income for the masses in the mountains. In 2030, China's forest stock volume will be more than An increase of 6 billion m in 2005 3 about. The development of the underforest economy is an important measure to consolidate the achievements of the reform of the collective forest tenure system. It is a main means to increase farmers' income in the post-forest reform period. Promote the sustainable development of characteristic economic forests and increase ...
