This invention discloses a method for preparing a rice seedling substrate based on rice and wheat straw, its products, and applications. This application converts rice and wheat straw into earthworm castings, optimizes the earthworm castings, and prepares a rice seedling substrate more suitable for rice seedling cultivation practices in the middle and lower reaches of the Yangtze River. The water retention capacity of this seedling substrate is significantly superior to that of general seedling substrates. When using the "running water" irrigation method, it can continuously supply water to the seedlings even without timely irrigation, ensuring robust root growth; it can continuously control the pH of the seedling substrate, significantly improving the seedling's root development; and it can increase nutrient retention, ensuring the formation of strong seedlings.

This invention discloses a method for preparing bio-organic fertilizer that reduces the incidence of tobacco root-knot nematodes. The bio-organic fertilizer consists of a fermentation substrate, microbial inoculant, and earthworm castings in a mass ratio of 10:0.2-0.4:2-3. The invention uses Bacillus subtilis, Trichoderma harzianum, and Bacillus mucilaginosus in a mass ratio of 15-25:8-13:30-40 to prepare the microbial inoculant. The fermentation substrate and microbial inoculant are mixed and fermented. The fermentation substrate includes cow dung, wheat bran, straw, and earthworm castings. The bio-organic fertilizer of this invention can reduce the incidence of tobacco root-knot nematodes and also promotes tobacco root growth and increases tobacco leaf yield.

The application discloses an earthworm manure compound substrate for improving tomato yield and quality and a planting method, and comprises the following steps: a substrate is prepared from the following components in percentage by volume: soil 10-50%, earthworm manure 40-80% and vermiculite 10%; and 0.05-0.1% of nitrogen fertilizer and live earthworms in the total mass of the substrate; the nitrogen fertilizer is added to the substrate as a seedling raising substrate, the water content of the seedling raising substrate is adjusted, the seedling raising substrate is loaded into a plug tray, tomato seeds are sowed, and seedling raising is carried out by controlling the environmental temperature; after the seedlings reach a planting standard, the seedlings are transplanted into a planting bag filled with the seedling raising substrate for planting; after the planting and seedling recovery are completed, the live earthworms are inoculated into the seedling raising substrate in the planting bag to obtain a compound substrate; the water content of the compound substrate is controlled during the whole growth period of the tomatoes; the tomatoes are subjected to hanging, pruning, branch beating and leaf picking treatments; and the tomatoes are harvested after the fruits are matured. The application realizes the best balance between high yield and high quality of the tomatoes.

The present disclosure relates to a vermicomposter. It is disclosed a vermicomposter comprising: a frame supporting all functional components above ground level, a housing comprising an open upper inlet configured to receive organic waste and a lower outlet configured to discharge vermicompost, and an extraction device arranged at the lower outlet, wherein the lower outlet comprises a plurality of spaced structural members forming gaps that define a at least partially open bottom surface extended laterally on at least one side of the housing, thereby allowing passage of vermicompost through said gaps, wherein the extraction device comprises at least one horizontally movable scraping mechanism extending across substantially the entire width of the lower outlet, the scraping mechanism being movable along a horizontal path parallel to the bottom of the housing so as to displace and remove the accumulated vermicompost through said partially open surface, causing the vermicompost to fall to a collection area below the frame.

The application discloses a soil conditioner for improving quality and yield of continuous cropping tomatoes, and raw materials of the soil conditioner include earthworm manure powder, sinomenium acutum powder, fallopia multiflora, limestone powder, humic acid, active adsorbent, composite microorganism, carboxymethyl hydroxyethyl cellulose, acrylamide, crosslinking agent, photoinitiator, catalyst and iron salt. The application also discloses a preparation method of the soil conditioner for improving quality and yield of continuous cropping tomatoes. The application adopts the compounding of the loaded microorganism and the earthworm manure powder, can quickly increase soil water stable aggregates, improve soil physical structure, enhance soil fertility, and has extremely remarkable effect of improving soil, and in combination with the sinomenium acutum and the fallopia multiflora, can not only show the inhibiting effect on fusarium oxysporum in the soil continuously cropped for 5-10 years, but also can continuously enhance soil enzyme activity.

This invention relates to the field of soil conditioning materials technology, and more particularly to a salt-tolerant earthworm castings-based dual-network microbial slow-release gel microsphere, its preparation method, and its application. By selecting earthworm castings as a filler, sodium alginate as an encapsulating agent, and desulfurized gypsum as a crosslinking agent, this invention constructs salt-tolerant earthworm castings-based dual-network microbial slow-release gel microspheres with high mechanical strength and high microbial encapsulation rate. These gel microspheres can effectively improve saline-alkali soils by increasing soil nutrient and organic matter content, improving microbial survival rate, and reducing soil pH and salinity. They possess advantages such as safety, high efficiency, low cost, and simple operation, and have broad application prospects.

This application discloses a method for preparing functional earthworm protein powder and earthworm casting organic fertilizer based on dry bed and intermittent feeding, comprising: aerobic composting and fermentation of livestock and poultry manure raw materials, laying them into a dry material worm bed as a habitat layer for earthworms; inoculating earthworm seedlings into the dry material worm bed; preparing a thin mud-like slurry using organic waste; adding functional materials during the preparation of the thin mud-like slurry or before feeding; uniformly applying the thin mud-like slurry with added functional materials to the surface of the dry material worm bed; intermittent feeding, controlling temperature and humidity, and maintaining ventilation; stopping feeding when the earthworm density reaches the harvesting conditions, separating the earthworms and earthworm castings, and collecting the functional earthworm bodies and functional earthworm castings separately; obtaining functional earthworm protein powder and functional earthworm casting organic fertilizer. This invention realizes the resource utilization of livestock and poultry organic waste, simultaneously producing high-value-added functional earthworm protein powder and high-quality functional earthworm casting organic fertilizer.
