Application device and method for arbuscular mycorrhizal fungi capable of recycling fertilizer

Abstract

The device comprises a fertilizer guide groove device, the interior of the fertilizer guide groove device is divided into a left chamber and a right chamber through a partition plate, bacterial fertilizer windows are formed in the side, close to the left chamber, of the fertilizer guide groove device at equal intervals, and buffer holes are formed in the partition plate at equal intervals; the method comprises the following steps: inoculating an arbuscular mycorrhizal fungi inoculant to a host plant, and planting and culturing on ridges, so that the arbuscular mycorrhizal fungi can be colonized on the root system of the host plant, and hyphae can extend and develop on the ridges and enter a left chamber in a fertilizer guide groove device through a bacterial fertilizer window so as to be in contact with a blended water and fertilizer solution; hyphae of the arbuscular mycorrhizal fungi are transferred to the plant water and fertilizer, water and fertilizer supply of the plant is met, meanwhile, the symbiotic effect of the arbuscular mycorrhizal fungi and the host plant is enhanced, water and fertilizer are isolated from soil, damage of chemical fertilizer to the property and structure of the soil is avoided, the water and fertilizer are regularly recycled and reused, and the yield of the soil is increased. The water and fertilizer cost is saved.

Description

technical field [0001] The invention relates to the technical field of biological bacterial fertilizer, in particular to an arbuscular mycorrhizal fungus application device and method capable of recycling and reusing fertilizer. Background technique [0002] With the development of ecological green agriculture, traditional chemical fertilizers are no longer suitable for large-scale application, and biological green fertilizers are developing rapidly, and various biological bacterial fertilizers have emerged as the times require. [0003] Although there are many kinds of biological fertilizers today, most of the current biological fertilizer products and application techniques follow the idea of ​​traditional chemical fertilizers. They are still widely fertilized and the application techniques are extensive. For example, the earliest developed rhizobia bacterial fertilizer, seedling After fertilization, although the plant growth effect is obvious in the early stage of fertili...

Problems solved by technology

[0003] Although there are many kinds of biological fertilizers today, most of the current biological fertilizer products and application techniques follow the idea of ​​traditional chemical fertilizers. Extensive application techniques, such as the earliest developed rhizobia bacterial fertilizer, after application at the seedling stage, although the plant growth effect is obvious in the early stage of fertilization, there is no corresponding application technology for maintaining efficacy in the middle and late stages. The popular Trichoderma bacterial fertilizer is also widely applied. After fertilization, only rely on the growth-promoting and bio-controlling effect of the bacteria itself, without the corresponding subsequent application management technology. Moreover, some chemical fertilizers or compound fertilizers are added to the bacterial fertilizers on the market today, and the rest of the growth-promoting effect on plants depends on The mineralization of soil nutrients by bacteria cannot play a role in some nutrient-poor southern soils

[0004]The nutritional symbiotic effect of arbuscular mycorrhizal fungi on the supply of nitrogen, phosphorus and potassium to host plants has long been expected by people, but there is no reasonable application of arbuscular mycorrhizal fungi. Fungal fertilizer and supporting high-efficiency application technology, that is, there is no high-efficiency application system for arbuscular mycorrhizal fungi that can be recycled and reused, resulting in the lack of efficient application technology for arbuscular mycorrhizal fungus-related biological fertilizers, and low efficacy in the later stage. Therefore, the present invention proposes an arbuscular mycorrhizal fungus application device and method that can be recycled and reused to solve the problems in the prior art
