The present invention provides biodegradable projectiles for toy launchers that contain viable seeds. When lost outdoors the projectiles do not pollute the environment but instead degrade naturally and the seeds grow into plants that enhance the landscape.

A seed delivery device that includes an enclosed container inside which is encapsulated one or more plant seeds and a medium. The medium may comprise one or more particulate materials, one or more aqueous materials, or a combination of one or more particulate materials and aqueous materials. The specific gravity of the entire device is greater than the specific gravity of water. The seed delivery devices may be used to address the planting of seeds in conditions where water is or may become present.

The present invention relates to a rice seedling substrate and a preparation method thereof, which is of the technical field of rice planting. The rice seedling substrate according to the invention was prepared from the raw materials includes the following by volume: 40-60% of dredging sediment, 30-50% of vegetable straw, and 10-30% of hickory shell. The rice seedling substrate according to the invention can not only turn waste into treasure to improve the recycling rate of sediment and agricultural and forestry waste resources, but also save the limited cultivated soils, reduce the production cost of rice seedling substrate, and promote the healthy and sustainable development of rice planting. Therefore, The inventive substrate has significant benefits in terms of economics, sociology and ecology.

The present invention relates to a device and method for sowing seeds. The invention relates more particularly to a device and method for sowing seeds as part of a plant. The system according to the invention comprises a separating device for separating a single seed relative to a remainder of the plurality of seeds, an optical recognition system (9) for recognizing the separated seed, a robot arm device (4) for picking up the separated seed and for sowing the picked-up seed, arid a control unit for controlling the separating device, the optical recognition system (9) and the robot arm device (4). With this system it is possible to sow seeds in a more accurate and less error-prone manner.

The present disclosure relates to an onion growing method, and more particularly, to an onion growing method that includes the steps of: (a) allowing onions to be dormant; (b) breaking the dormancy of the onions; (c) planting the onions of which dormancy is broken in a field; (d) growing the planted onions to produce a plurality of stems and bulbs divided from the respective onions; and (e) harvesting the plurality of stems and bulbs. According to the present disclosure, the onion growing method does not have any limitation in growth time unlike a conventional onion growing method, reduces a period of growth, and drastically increasing onion yield to raise a farmer's profits. Also, the onion growing method stably supplies onion stems and leaves, thereby providing various profits through onions.
