A controlled-release aggregate capsule for soil and water conservation plant measures and its preparation method

Abstract

The invention discloses a controlled-release granule capsule used for a plant measure of conservation of water and soil and a preparation method thereof. The controlled-release granule capsule capableof making soil and a fertilizer coexist, used for the spray-seeding plant measure, and suitable for concrete slope surface, rock surface, steep slope surface, counter-slope surface, common slope surface, gravel surface and soil slope surface and the preparation method thereof are provided. The spray-seeding speed is high, the quality is good, the equipment requirements are low, the capsule can resist water flow and freezing erosion and is wide in application range and little in waste, and industrialization and standardization can be easily formed.

Description

technical field [0001] The invention belongs to the field of water and soil conservation, and relates to planting measures on slopes in aspects of greening and ecological management. In particular, it involves spraying and greening measures on concrete surfaces, rock surfaces, steep slopes, reverse slopes and other slopes. Wide application range, simple equipment, good quality, short construction period, less waste, easy to form industrialization and standardization. Background technique [0002] At present, in water conservancy and hydropower, highways, railways, port and shipping transportation and other industries, the spraying and greening measures adopted on the rock surface after manual work or the slope surface after shotcrete, as well as the steep slope and reverse slope mainly include high-order aggregate spraying. method, foreign soil spraying method, hydraulic spraying method, CBS vegetation concrete spraying method, three-dimensional net vegetation spraying meth...

AI Technical Summary

Problems solved by technology

In addition, in the high temperature season, the temperature of the concrete surface of spray anchor or lattice frame, and rock surface is relatively high. Even if water-retaining materials such as coconut powder and water-retaining agent are used, the water in the thin substrate layer is still very easy to transpire, which will lead to poor plant survival rate. Low or relatively limited survival time

Because the CBS vegetation concrete spraying method uses more consolidation materials, although it solves the water erosion, it also partially solves the problems of frost resistance and drying shrinkage expansion, but the soil matrix nutrients are low, easy to harden, and water is easy to evaporate.

There is also a common problem in the above-mentioned technologies, which is that excessive nutrients in the early stage lead to burning or crazy growth, and in the middle stage, due to the poor environmental resistance caused by crazy growth, they are in a dying state, and in the later stage, plants with nutrient depletion are not easy to survive.
