Method for cultivating and managing inter-planted mahonia fortunei in walnut forest in rocky desertificated area

Abstract

The invention discloses a method for cultivating and managing inter-planted mahonia fortunei in a walnut forest in a rocky desertificated area. The method comprises following steps: (1) picking a walnut forest for inter-planting and preparing the walnut forest; (2) accelerating germination of walnut and mahonia fortunei; (3) growing the seedlings of walnut and mahonia fortunei; (4) carrying out domestication and thinning of walnut and mahonia fortunei; (5) fix-planting seedlings of mahonia fortunei in the walnut forest; (6) removing the weeds and performing irrigation; (7) under inter-plantingconditions, fertilizing walnut trees and mahonia fortunei; (8) controlling the diseases and pests; and (9) harvesting fruits and preparing seeds. Mahonia fortunei is inter-planted in a walnut forest,spatial distribution characteristics of different plants are fully utilized, nutrients in different soil layers can be fully absorbed, the soil utilization rate of the walnut forest is increased, thedesertification damage is reduced; at the same time, the mahonia fortunei can increase the income of walnut farmers, and walnut plantation has a long term effect in relieving desertification.

Description

technical field [0001] The invention belongs to the technical field of economic forest cultivation, and in particular relates to a cultivation management method for interplanting under walnut forests in rocky desertification areas. Background technique [0002] Rocky desertification is a land degradation phenomenon in which karst is extremely developed under tropical and subtropical monsoon climate conditions, surface vegetation is destroyed by man-made, rainwater erosion causes serious soil loss, and large areas of bedrock are exposed. It is an extreme form of land degradation in karst areas. It is defined internationally as: the process of drought, land degradation in semi-arid and sub-humid areas, and changes to desert landscapes caused by climatic factors and human activities. Rocky desertification and karst fragile ecological governance are one of the focuses of current global sustainable development strategy research. [0003] At present, the land use in rocky deserti...

2. Cultivated land resources are scarce and land productivity is low

Moreover, most rocky desertification areas belong to dry land, which belongs to slope farmland without effective irrigation. Due to the topographical conditions of high mountains and steep slopes, unique karst double-layer geological structure, and climate characteristics of abundant and concentrated precipitation, limited land resources are not only extremely easy to It is lost by surface runoff, and it is easy to seep from pores to the ground and be lost. It is difficult to store and retain water in the soil, and nutrients are lost, and the level of land productivity is low.

3. The poor population is concentrated and the economic development capacity is weak

Moreover, most of the rocky desertification areas are located in the "old, young, border, mountainous, and poor" areas of Guangxi. Most of the local GDP comes from planting, breeding, and some low-end service industries. Farmers can only live in rocky crevices Living by planting low-value dryland crops such as corn, which is a typical planting pattern of wide planting and low harvest, it is difficult to get rid of poverty
