Provided is a method for hydroponic culture of a plant of the family Asteraceae which is suitable for growing the roots of the plant of the family Asteraceae. The method for hydroponic culture of a plant of the family Asteraceae includes a hydroponic culture step including culturing a plant of the family Asteraceae while adjusting the amount of a nutrient solution so that 10 to 50% of the total length from the tip of the tap root of the plant of the family Asteraceae is soaked in the nutrient solution, and the rest of the tap root is exposed to a gas.

Growing system for growing plants, for example vegetables and ornamental plants, includes a container tray (1) which is floatably arranged in a liquid reservoir (14). The container tray (1) is configured to float on nutrient water (6) during use and has at least one opening (4) which is arranged in a tray bottom (2) of the container tray (1) for bringing a growth substrate (11) which is arranged on the container tray (1) into contact with the nutrient water (6). The container tray (1) is a substantially flat container tray (1) which includes an upright tray edge (3), and wherein the at least one opening (4) has an upright opening edge (5) having a height which is such that the growth substrate (11) is situated above a water line of the nutrient water (6) during use.

The invention concerns novel nitrification inhibitors.

Various implementations of the present disclosure are directed systems and methods of preparing a fertilizer product from cactus. The method includes grinding cladodes of one or more cactus plants into ground cactus and selecting prickly pear fruits from the one or more cactus plants. The method further includes combining the ground cactus, the selected prickly pear fruits, water, and a ruminal fluid in a first container to form a mixture. The method further includes storing the mixture in the first container for a first time period such that the mixture reacts to form a digestate. The method further includes storing the digestate in the first container or a second container for a second time period such that the digestate forms the fertilizer product.

The present disclosure provides an Anabasis aphylla field planting device, falling within the technical field of plant planting. The planting device includes a frame body of a mobile machine, a planting frame and a sprinkling irrigation system. A top of the planting frame is arranged with a seedling clamping and conveying mechanism; the seedling clamping and conveying mechanism includes a conveying rod shaft, a rotary supporting and feeding piece, an autorotative driving ring piece, a clamping piece and a driving piece; and the clamping piece includes a fixed supporting rod and a U-shaped clamping body. The planting device is simple in structure and can automatically support and feed the planting seedlings; and after the planting seedlings are filled with soil and irrigated, the supporting and feeding mechanism is automatically separated from the planting seedlings, without manual operation and having high planting efficiency.

The objective of the invention is to provide a plant activator having a resistance to the wash-off and a superior handleability, transportability and storage stability. A powdery plant activator comprising, at least one compound selected from an oxo fatty acid or a derivative or a salt thereof and a hydroxy fatty acid or a derivative or a salt thereof, and an unsaturated fatty acid (excluding an oxo fatty acid and a hydroxy fatty acid).

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.
