The invention concerns novel nitrification inhibitors.

The present invention discloses a cultivation method for the rapid propagation of Davidia involucrata winter buds. The method includes the following steps: (1) collecting winter buds of Davidia involucrata as explants; (2) disinfecting and sterilizing; (3) primary culture of the winter buds; (4) propagation cultivating; (5) cultivating of the strong seedlings; (6) cultivating roots; (7) acclimatization and transplanting; (8) water and fertilizer management. The method of the present invention can effectively promote the artificial propagation of Davidia involucrata and improve the survival rate thereof.

Provided is a light emitting device that includes a light emitting element having a light emission peak wavelength ranging from 380 nm to 490 nm, and a fluorescent material excited by light from the light emitting element and emitting light having at a light emission peak wavelength ranging from 580 nm or more to less than 680 nm. The light emitting device emits light having a ratio R/B of a photon flux density R to a photon flux density B ranging from 2.0 to 4.0 and a ratio R/FR of the photon flux density R to a photon flux density FR ranging from 0.7 to 13.0, the photon flux density R being in a wavelength range of 620 nm or more and less than 700 nm, the photon flux density B being in a wavelength range of 380 nm or more and 490 nm or less, and the photon flux density FR being in a wavelength range of 700 nm or more and 780 nm or less.

Provided herein are methodology and composition for use of any nut (such as almond, walnut, or pistachio) or legume (peanut) shell and/or husk material in a growing substrate, with or without other components such as peat, perlite, or coir; for plant growth, whether it be used in its whole form or some reduced form such as, having been chipped or ground, and whether composted or not.

A self-contained closed aquaponics system comprises an aquarium tank attached side-by-side to a water container for growing plants, having a shared side. An electrically powered water pump streams the water from the aquarium tank via a pipe to the bottom of a compartment in the water container. When the water in the water tank exceeds a pre-set water level, the water are poured back to the aquarium tank via a recess or slit in the shared side. The compartment may comprise a bio-filter that is a sponge filter, a foam cartridge filter and the undergravel filter. The aquarium tank or the water container may be rectangular or cuboid shaped. A cover adapted to cover the water container may include multiple openings for mounting plants in pot nets therein, where roots of the plants are fed from the fish excretions in the aquarium tank after being filtered by the bio-filter.

This invention relates to methods and materials for providing a benefit to a plant by associating the plant with a complex endophyte comprising a host fungus further comprising a component bacterium, including benefits to a plant derived from a seed or other plant element treated with a complex endophyte. For example, this invention provides purified complex endophytes, purified complex endophyte components such as bacteria or fungi, synthetic combinations comprising said complex endophytes and/or components, and methods of making and using the same.

Provided is a method for interplanting grape and Polygonatum kingianum in a photovoltaic (PV) power plant. The method includes: building a grapevine traction frame which is higher in south and lower in north in a space formed by a plurality of PV modules in the PV power plant, the grapevine traction frame includes a plurality of uprights, a plurality of traction crossbars, a plurality of supporting bars and a wire mesh; making a grape ridge below the south of each PV module and planting grape seedlings; maintaining two branches for each of the grape seedlings in the same year of grape planting, and pulling the two branches along the traction crossbar located in south; pulling branches grown out of arm bud points southwards onto the wire mesh in the next year of grape planting; sowing and ploughing a green manure, making planting beds in a shade and planting Polygonatum kingianum.
