An artificial seedbed used in growing vegetation. The artificial seedbed comprises a base layer formed of a biodegradable product having a porosity and wet density that permit a root of the desired vegetation to penetrate the base layer and establish the vegetation for growing. The artificial seedbed also comprises an intermediate layer comprising a plurality of seeds for use in growing the desired vegetation. A cover layer cooperates with the base layer to form an envelope about the intermediate layer. The cover layer can be coextensive with the base layer and secured to the base layer by a bonding agent. The cover layer is formed of the same or different biodegradable product as the base layer. The material used in the cover layer permits the sprouting vegetation to penetrate it during the growing process.

The invention relates to a rapid composting microbial inoculum of agricultural wastes and a method for preparing organic fertilizer from the same, belonging to the field of waste resource recycle. In the invention, a strain NJZ5 capable of rapidly decomposing various wastes rich in cellulose at 50 DEG C is separated. The strain NJZ5 is inoculated in a fermentation cylinder, and the obtained fermentation broth contains culturable colonies the number of which is no less than 1*109 per milliliter; after the fermentation broth and an adsorbent rice bran are mixed uniformly, the product of the rapid composting microbial inoculum of agricultural wastes can be obtained, wherein the content of the agricultural wastes in the NJZ5 strain can be no less than 1*108 per grame. The NJZ5 composting microbial inoculum can remarkably improve the composting temperature and shorten the composting period, and can control the composting period within about 30 days.

The invention discloses an intelligent aerobic composting reactor system. The reactor system comprises a reactor tank body, a programmable logic controller (PLC) control system, a gas distribution system and a water distribution system, wherein a feed port, a gas outlet and a water supplement port are formed in the top of the reactor tank body, and the water supplement port is connected with the water distribution system; the bottom of the reactor tank body is provided with a leachate collecting port; the lower part of the reactor tank body is provided with a discharge port and a gas inlet, and the gas inlet is connected with the gas distribution system; the discharge port and the gas inlet are arranged at the upper part and the lower part of a gas distribution screen respectively; and the gas distribution system and the water distribution system are all connected with the PLC control system. Due to good design of an insulating layer of the reactor system, the fermentation effect and product quality can be effectively guaranteed; the intellectualization of the experimental simulation and production process can be realized based on the control system of a multi-sensor; and due to design of a tail gas purifying system and the leachate collecting port, the ecological environmental protection of the composting fermentation process can be effectively realized.
