The invention belongs to the technical field of soil microbial control, and discloses a compound microbial agent for treating mine tailing polluted soil, the compound microbial agent comprises a coxsackie P1-4-containing bacterial liquid and a stenotrophomonas R5-containing bacterial liquid in a volume ratio of (1-2): (1-2), and the OD600 value of the coxsackie P1-4-containing bacterial liquid and the OD600 value of the stenotrophomonas R5-containing bacterial liquid are independently 0.5-1.5. The invention further discloses a preparation method of the complex microbial inoculant and application of the complex microbial inoculant in treatment of mine tailing polluted soil. The coxakia P1-4 and the stenotrophomonas R5 screened by the invention are both derived from a cadmium-resistant environment (rhizosphere of miscanthus sinensis and endogenous rice), and have natural tolerance to heavy metal stress; the microbial agent prepared by compounding the microbial agent shows extremely strong adaptability and repair pertinence to typical acidic and cadmium-lead combined polluted soil in mine tailing areas, and solves the general problems of low survival rate and function failure of a common microbial agent in a severe tailing environment.

The invention discloses a compound microbial agent for ensiling miscanthus sinensis and application of the compound microbial agent. The microbial agent is prepared from lactobacillus plantarum LW8 (CGMCC NO.28108) and lactobacillus plantarum K3 (CGMCC NO.34845) according to the viable count ratio of (1.5 to 2.5): 1. The method comprises the following steps: chopping miscanthus sinensis, adjusting the water content, spraying a zymophyte solution prepared from the complex microbial inoculant and brown sugar, and carrying out vacuum sealing and anaerobic fermentation to obtain the miscanthus sinensis silage. The complex microbial inoculant utilizes rapid acid production of LW8 and later-stage stability of K3 to synergistically promote lactic acid fermentation, can rapidly reduce the pH value, significantly inhibit protein degradation (ammoniacal nitrogen / total nitrogen is less than or equal to 0.70%) and reduce the fiber content, and finally obtains miscanthus silage with stable fermentation quality and high nutritional value.

This invention belongs to the field of mine wasteland remediation technology, specifically disclosing a plant-microorganism synergistic method for mine wasteland remediation. The method includes the following steps: mixing organic waste, an alkaline amendment, and a first compound microbial agent with the topsoil of the mine wasteland, and conducting aerobic cultivation to obtain pretreated soil; tilling the soil, planting Miscanthus sinensis, and cultivating until the Miscanthus sinensis grows stably; planting ramie between the Miscanthus sinensis rows, spraying a second compound microbial agent on the soil surface between the rows, and harvesting the above-ground parts of the Miscanthus sinensis and ramie after 25-35 days to determine the metal accumulation; detecting the target metal content in the soil, and if the target is not reached, retaining the root system for multiple rounds of remediation. This method can effectively adsorb heavy metals in the soil, solving the problems of low remediation efficiency, long cycle, lack of resource consideration, and insufficient restoration of soil ecological function, providing an efficient, economical, and environmentally friendly solution for the sustainable ecological restoration of mine wastelands.

The utility model relates to the technical field of triarrhena lutarioriparia picking, in particular to equipment suitable for rapidly picking triarrhena lutarioriparia, which comprises a rod body, a mounting plate is arranged in the rod body, a first air cylinder and a second air cylinder are arranged on the mounting plate, and a connecting seat is arranged at the output end of the first air cylinder. A cutting tool is arranged at the output end of the second air cylinder, a sliding plate and a swing arm are arranged on the portion, between the first air cylinder and the second air cylinder, of the mounting plate, the connecting base is connected with the sliding plate, a sliding groove is formed in the plate face of the sliding plate, a thrust block is arranged at the front end of the swing arm, and a sliding ball is arranged at the rear end of the swing arm. The sliding ball is arranged in the sliding groove and slides along the sliding groove. In the picking process, it is only needed to place the to-be-picked southern diels into the cutting notch, automatic and rapid picking can be achieved through front-back stretching and retracting of the cutting tool, manual work does not need to participate in cutting work, the working intensity can be lowered, and meanwhile a large amount of time can be saved.

Low moisture content at harvest is important since green biomass material is not suitable for many applications such as for combustion in power stations. It is unusual to find a Miscanthus variety that is both cold tolerant and / or vigorous but that dries down well in years with mild winters. A mild winter may reduce the amount of usable biomass that is obtained from Miscanthus plants, including from cold hardy varieties that will stay green and fail to dry down properly at the end of a season unless there is a heavy prolonged frost. To address this issue, the present description relates to the production of increased usable biomass yield that may be obtained at harvest from Miscanthus plants that are cold tolerant, vigorous, and which also have good dry down properties during mild winters. The present methods include plants and methods for regenerating plants from a cell, rhizome, or cutting of a Miscanthus sacchariflorus x Miscanthus sinensis cross, and then selecting one or more regenerated plants that produce increased usable biomass and / or increased carbon sequestration.
