Description

Seedling tray and device for feed watering

The present invention relates to a tray for seedlings and an irrigation device, and the conventional method for sprinkling heads, such as sprinklers used for irrigation of seedlings during strawberry seedlings, causes not only water droplets to cause anthrax, but also high temperature and humidity conditions. There is a problem of making a favorable environmental conditions for germination of pathogens, the present invention seedling seedlings such as strawberries in a tray formed with a plurality of ports while seedlings are planted without splashing water droplets to prevent the occurrence and spread of anthrax It is to allow a constant and uniform amount of watering to the topsoil.

Korea's strawberry cultivation area in 2006 is 6,813 ha, with annual output of 205,307 tons, the third and fourth largest in the world. According to the strawberry cultivation area, about 68 million rice seedlings must be grown in about 1100 ha of seedling area.

Strawberry seedlings are seasonally high in summer and use of pots with low rooting volume to promote flower differentiation is common, requiring frequent watering every day. Here, water droplets such as sprinklers installed for watering of seedlings not only disperse anthrax bacteria, but also rapidly spread anthrax by creating high temperature and high humidity conditions.

In order to produce 1ha of strawberry, it was necessary to form 3000 runners in winter and run runners in spring, and then secure seedlings of more than 100,000 weeks from the end of May, and then go through a two-month nursery period. This is invested. Since the seedlings of strawberries have passed the nursery period of more than 60 days after independence, the ability to produce fruit is not available. . The biggest threats to securing seedlings during the seedling period are the loss of seedlings and poor growth of seedlings caused by anthrax.

The head sprinkler irrigation method using the existing sprinkler is difficult to uniformly grow seedlings due to the difficulty of uniform irrigation because the spraying range overlaps or cannot be sprayed depending on the location, and water droplets may be a means of scattering anthrax. In addition, it creates a favorable environment for germination of pathogens by making high temperature and high humidity conditions. Strawberry anthrax is the primary source of infectious disease, such as mother strain and soil, and is actively inhibiting the introduction of pathogens by seedling methods and chemical control, such as segregation from soil and use of non-foresting facilities. However, once anthrax bacteria are introduced, water droplets derived from sprinklers installed for watering of seedlings become a means of scattering anthrax bacteria, creating a high temperature and high humidity environment in which pathogens can germinate well with high temperatures in summer. For this reason, a bottom irrigation method has been developed in which water droplets do not fly to the ground of crops, but some attempts have been made.

In addition, the 32- and 30-hole trays, which are mostly used by farmers, can produce 200-150 strains of seedlings per ㎡ of seedling area, so they can be mass-intensively produced in a small area, but the seedlings are caused by excessive competition between individuals in a small area. Rather than increasing the leaf area, it is easier to paint and there are fewer crowns.

The present invention has been made to solve the above problems, in the present invention was devised a method for uniformly supplying nutrients and water to the top soil portion located in the roots for each seedling in a method other than the head coronary water, mass intensive production It is to provide a watering device that prevents the spread of anthropogenic trays and anthrax germs, which are capable of producing uniform seedlings without any differences between individuals. .

In order to achieve the above object, the present invention provides a plurality of ports, which are planted vertically and horizontally on the upper surface of the tray, at regular intervals, and a front and rear, left and right adjacent ports are formed in cross-shaped irrigation channels formed crosswise. It provides a seedling port, and a distributor connected to the irrigation hose is installed between the irrigation hoses so that the water supplied from the irrigation hose is supplied to each irrigation channel through the distributor so as to flow uniformly into each port.

The present invention also provides a watering device for the seedling port, the watering device is a main water supply pipe connected to the water tank, a watering hose connected to the main water supply pipe and a plurality of distributors installed in the middle of the watering hose The distributor includes an inlet and outlet connected to the watering hose and a plurality of outlets for discharging water to the watering passage, the watering hose has a closed loop form, both ends of which are connected to the main water supply pipe. In this way, a watering device is provided so that uniform water pressure can be applied over the entire area of the watering hose.

The seedling tray of the present invention can be applied to a new irrigation method that can replace the existing two head irrigation method, and if the seedling is grown by installing a watering device on the seedling tray, the uniform seeding is made and uniform nurturing is achieved. It is possible to produce high quality seedlings, and the amount of water required for watering of seedlings is much higher than the amount directly irrigated to the seedlings by conventional head sprinkler methods such as evaporation, passages, and facilities. Compared to many, it can save considerable amount, and because water droplets do not blow out during watering, it does not cause the problem of spreading anthrax germ, so it is possible to prevent the death of seedlings due to anthrax caused by anthrax or the death of anthrax. It has a useful effect such as.
