Description

Tray for seedlings {Tray apparatus for rasing seedings}

The present invention relates to a tray for seedlings, and more particularly, to a tray for seedlings capable of supplying water to plants by combining a drip tube.

Strawberry is one of the fruits preferred by consumers due to its excellent taste and nutrition, and the demand for it is increasing every year. In order to secure the supply of strawberries, specialized nurseries and farms are putting great effort into the production of seedlings for the next year's strawberry production.

Unlike other plants that propagate by seeds, strawberries are propagated in a way that a stem usually called a 'runner' extends from the mother seedling, takes root on the ground, and grows as a single individual. When the seedlings bred during the seedling production process grow to a certain size, they are stored in a low-temperature condition such as a refrigerator, and then transferred to the ground or a container for hydroponics.

For this reason, seedling is the most important step in the strawberry production process, and it is the most important step to secure healthy seedlings. Recently, as improved or new varieties of strawberries are developed, there is a demand for a seedling tray capable of effectively increasing seedling production in order to quickly supply a large amount of seedlings to farms.

Korean Patent Registration No. 10-1823253 discloses a strawberry cultivating apparatus using individual seedling pots that can produce uniform and healthy strawberry seedlings by planting runner seedlings generated from mother seedlings of strawberries in individual seedling pots.

Strawberry cultivating apparatus using individual seedling pots as described above improves efficiency of strawberry production by facilitating control of nitrogen, which affects strawberry flower and differentiation, as the runner and soil are isolated in individual seedling pots having a certain rhizosphere capacity. have the advantage of being able to However, such an apparatus for growing strawberries using individual seedling pots requires frequent irrigation. Watering through a method of scattering water droplets such as a sprinkler is apt to spread pathogens such as anthrax as the water is atomized by contact with water and air. There is a problem in creating a high-temperature and high-humidity environment.
