Abstract
Description
Technical Field
[0001] The utility model relates to the field of microbial testing, in particular to a growth core testing device for AMF ecological functions. Background Art
[0002] Mycorrhiza is a symbiotic relationship between mycorrhizal fungi in the soil and the roots of higher plants. It is one of the most common symbiotic phenomena in nature. Mycorrhizal fungi are divided into ectomycorrhizal fungi and endophytic mycorrhizal fungi. Endophytic mycorrhizal fungi are also called vesicular arbuscular mycorrhizal fungi, referred to as arbuscular mycorrhizal fungi. AMF is a type of indigenous microorganisms commonly found in farmland soil. Arbuscular mycorrhizal fungi can form mycorrhizal symbioses with most crops, woody plants, and herbaceous plants. Studies have shown that arbuscular mycorrhizal fungi can improve the stress resistance of plants, such as drought resistance, heat resistance, waterlogging resistance, salt resistance, resistance to heavy metal ions, disease resistance, cold resistance, acid resistance, and insect resistance. However, arbuscular mycorrhizal fungi cannot reproduce in vitro and can only reproduce after symbiosis with the roots of living plants.
[0003] Most of the existing arbuscular mycorrhizal fungi growth core test devices use partitions as partitions, and use cultivation containers on both sides of the partitions. Arbuscular mycorrhizal fungi are planted in the cultivation containers on one side and then cultivated for comparative experiments. They can only ensure the impact on the soil under natural conditions, but cannot ensure that the environmental conditions at both ends of the fixed partition are completely the same. The lack of airtightness may lead to deviations in the experimental results. At the same time, they generally only make one sample for the experiment, which makes the experimental device lack diversity and is inconvenient to sample the soil. Utility Model Content
