Problems solved by technology

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

Embodiment Construction

[0062] The technical solution of the present invention will be further described below, but the present invention is not restricted in any way. Any changes and substitutions based on the present invention belong to the protection scope of the present invention.

[0063] The present invention is a cultivation management method for interplanting Ten Major Meridians under walnut forests in rocky desertification areas. The specific operation steps are as follows:

[0064] Step 1. Site selection and site preparation: select walnut forests in rocky desertification areas (including flat land, slopes and rocky mountains) as the area for interplanting the top ten merits. The selected walnut forest planting row spacing is ≥5m, 8 years old or less, canopy closure Between 0.3 and 0.5, the growth is medium; in the middle and late March of the spring of the year when the ten major achievements were planted in the walnut forest area, the selected walnut forest land was deep-turned 25cm-30cm, then ...

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 specifically relates to a cultivation management method for interplanting Ten Major Meridians under walnut forests in rocky desertification areas. Background technique [0002] Rocky desertification is a phenomenon of extreme karst development under tropical and subtropical monsoon climate conditions, ground vegetation being destroyed by man-made damage, severe soil erosion caused by rain erosion, and land degradation in a large area of ​​exposed bedrock. It is an extreme form of land degradation in karst areas. Internationally, it is defined as the process of land degradation in arid, semi-arid and semi-humid areas and changes to desert landscapes caused by climatic factors and human activities. The control of rocky desertification and karst fragile ecology is one of the focuses of current global sustainable development strategy research. [0003] At present, the land use in th...
