Kalanchoe daigremontiana planting method and plant restoration system

Abstract

The invention discloses a kalanchoe daigremontiana planting method and a plant restoration system, and mainly relates to the field of plant cultivation and heavy metal restoration. According to the method, the effect of efficiently restoring heavy metal lead and zinc polluted soil in a short period is achieved through soil water permeability treatment, as well as earlier-stage culture, individual selection and planting culture of kalanchoe daigremontiana. According to the plant restoration system, seedlings on the planted and cultured kalanchoe daigremontiana maternal plants are stimulated, so that circulating type plant restoration of the kalanchoe daigremontiana is realized; by arranging the detachable and splicable fence strips, the working condition adaptability of the restoration system is greatly improved, construction operation of workers is facilitated, and the cost of the kalanchoe daigremontiana in the plant restoration process is reduced; by arranging the kalanchoe daigremontiana planting device reasonable in structure and a monitoring system of the kalanchoe daigremontiana planting device, kalanchoe daigremontiana seedlings poor in growth capacity are eliminated while monitoring and meeting the environmental requirements, and the plant restoration efficiency and effect are improved.

Description

technical field [0001] The present invention relates to the fields of plant cultivation and heavy metal environmental conservation and restoration, in particular to a planting method and a phytoremediation system of large leaves falling to the ground. Background technique [0002] As important mineral resources in my country, lead and zinc ore are widely used in electrical, mechanical, military, metallurgy, chemical industry, light industry and pharmaceutical industries, and occupy an important position in non-ferrous metal resources. China is also a country with large reserves of lead and zinc ore. In the world, China, Australia, Peru, Mexico, the United States, Canada and other countries are in the forefront of the world. my country's lead-zinc ore resources are widely distributed, spanning 9 provinces. Yunnan, Inner Mongolia, Guangxi, Shaanxi and other places are the main producing areas of lead-zinc ore , In recent years, China's domestic non-ferrous metal output and deman...

Problems solved by technology

Phytoremediation methods can be mainly classified into plant volatilization, plant stabilization and plant extraction methods, which have obvious advantages and have little impact on the soil, but the existing phytoremediation disadvantages also exist: the growth of plants is limited, and the size of individual plants is basically the same. Stereotype, the amount of heavy metal pollution that can be absorbed is limited; the ability to adsorb pollution is limited by its own characteristics, and many hyperaccumulator plants are wild plants, which are difficult to cultivate and the plants are small, which affects the adsorption capacity; the environment required for plant growth is insufficient in mine soil , the soil is poor, and the branches, leaves and flowers will inevitably fall and be damaged during the growth of the plants, and the pollution adsorbed in the body will return to the soil without treatment; it takes time for the plants to grow, resulting in a long repair cycle
