Problems solved by technology

[0007] In order to solve the technical problem of decoupling of ecology and production function synergy after artificial afforestation in rocky desertification areas, the purpose of the present invention is to provide a method for synergistic improvement of ecology and production functions suitable for rocky desertification control. The adaptive restoration of rocky desertification with a simple process and both ecological and production value simplifies the planting process, reduces soil cultivation disturbance, optimizes tending management, builds a suitable habitat for moss growth, and gives full play to the "moss-moss" The ecological service function of the composite system improves the way of picking leaves, improves the yield of mulberry trees and the quality of branches and leaves

Embodiment 1

[0037] A method for synergistic improvement of ecology and production functions suitable for rocky desertification control, the steps of which are:

[0038] (1) There is no need to level the land, just remove the weeds on the ground. In the winter of the previous year of afforestation, open pits at a row spacing of about 1.5×1.5m. The length, width, and depth of the pits are 40-50cm and 40cm respectively. ~50cm, 20~30cm. Then, apply about 200g of fully decomposed cow dung in each pit as a base fertilizer, and cover with a layer of 5-10cm thick topsoil as an isolation layer. 300 pits can be opened per mu of land.

[0039] (2) The cutting propagation time is May, when the temperature is about 25°C and the precipitation is relatively abundant. Select mature and robust, no pests and diseases, tree (year) age of 3 years as the parent tree, and choose the annual lignified shoots in the mother tree as cuttings. It is required that the spikes develop normally, have no pests and dis...

Embodiment 2

[0049] A method for synergistic improvement of ecological and production functions suitable for rocky desertification control, including the following main steps:

[0050] (1) Soil selection: In December of the year before planting the mulberry tree, open pits after removing weeds on the ground. The row spacing of the pits is 1.8×1.8m, and the length, width, and depth of the pits are 50cm, 50cm, and 25cm, respectively. . Then, apply about 200g of fully decomposed cow dung in each pit as a base fertilizer, and cover with a layer of 8cm thick topsoil as an isolation layer. There are 220 pits per mu.

[0051] (2) Heading collection and planting: In May of the second year, a mature and robust tree with no pests and diseases and an age of 2 years was selected as the mother body, and the annual lignified twigs in the mother tree were selected as cuttings. The selected cuttings developed normally and were free from diseases and insect pests. Use branch scissors to cut the upper en...

Embodiment 3

[0059] A method for synergistic improvement of ecology and production functions suitable for rocky desertification control, the steps of which are:

[0060] Concrete implementation steps are basically the same as embodiment 1, the difference is:

[0061] In step (1), in this embodiment, there are many exposed bedrocks in the rocky desertification area. According to the actual situation, the exposed bedrocks are avoided, and the method of "seeing needles" is used to open pits, and the row is adjusted according to the actual conditions of exposed bedrocks. Spacing and pit size. Due to the large amount of exposed bedrock, 243 pits were actually opened per mu of land.

[0062] In step (2), the thickness of soil covered by the cuttings is about 10 cm above the ground.

[0063] In step (3), the amount of compound fertilizer added is 35g per plant.

[0064]In step (4), the amount of phosphate fertilizer added is 60g per plant, and the amount of compound fertilizer added is 35g per...

Abstract

The invention discloses an ecological and production function collaborative improvement method suitable for stony desertification treatment, which comprises the following steps: 1) strong seedling cultivation: (1) soil selection: removing ground weeds without land leveling; (2) planting time: planting in April to May with mild climate and abundant rainfall; (3) collecting cutting slips: selecting matured and robust paper mulberry without plant diseases and insect pests as a parent body; (4) the cutting method: vertically putting the scions into the pits, enabling oblique cuts to cling to soil in the pits, and enabling the cutting depth not to bury axillary buds; and (5) covering the cuttings with soil; 2) tending management: (1) fertilizing; (2) performing moss transplanting; (3) forest land management: clearing and removing scattered dry branches and fallen leaves in the paper mulberry forest land; (4) supplementing moss; and (5) winter management: cutting off from the trunk of the paper mulberry before winter each year to promote branch germination in the next year; and 3) picking branches and leaves. The method is easy to implement, the treatment process is simple, rocky desertification adaptive restoration with ecological and production values is achieved, soil tillage disturbance is reduced, tending management is optimized, and the yield of paper mulberry trees and the quality of branches and leaves are improved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration in rocky desertification areas, and more specifically relates to a method for synergistically improving ecology and production functions suitable for rocky desertification control, which is suitable for ecological restoration in rocky desertification areas and the development of alternative herbivorous animal husbandry. Background technique [0002] The karst ecosystem (also known as the karst ecosystem) accounts for 1 / 3 of China's total land area, and the continuous exposed areas of bedrock are concentrated in Southwest China. The karst development in this area is intense, the contradiction between human and land is sharp, and the ecosystem is extremely fragile. Under the disturbance of human cultivation, soil erosion is rapid and severe, and land degradation characterized by rocky desertification is serious. Under the interaction of fragile ecological environment, huge population...
