Technical Field

[0001] This utility model relates to the field of rice seedling cultivation technology, specifically to a high-temperature resistant rice seedling cultivation device with adjustable spacing. Background Technology

[0002] Rice seedling raising involves cultivating rice seedlings in nurseries, hotbeds, or greenhouses in preparation for transplanting to fields. In agricultural production, rice seedling raising has advantages over direct seeding, such as saving seed usage, extending the crop's growing season, promoting early maturity, increasing yield per unit area, and saving breeding time. It can also shorten the rice planting time, making it easier to plant in fields and improving land use efficiency.

[0003] Chinese Patent CN107736157A discloses a rice seedling raising device, including a seedling frame and seedling trays. The seedling frame consists of a support rod and a mounting plate frame. The mounting plate frame has placement slots of the same size arranged on it, and seedling trays are installed in the slots. Each seedling tray consists of a tray body, a frame, and a seedling tray. The bottom of the tray body has an opening, and a movable plate is installed inside the opening. The movable plate consists of a plate body and a rotating shaft. This rice seedling raising device is simple and convenient because the mounting plate frame is installed on the support rod using matching posts and holes. When installing the seedling frame, simply lift the mounting plate frame to detach the posts from the holes. Furthermore, based on the movable plate installed at the bottom of the tray body, when changing the soil, simply pull down the movable plate to allow the soil to fall off, thus preventing damage to the seedlings when changing the soil.

[0032] To address the issue of existing rice seedling raising devices failing to guarantee seedling cultivation effectiveness due to high temperatures during practical use, please refer to... Figure 1 - Figure 5 This embodiment provides the following technical solution:

[0033] In this embodiment, the water inlet of the active spray frame 2 is connected to a water pump, and a number of spray holes 201 are evenly distributed on the surface of the active spray frame 2.

[0034] The movable seedling box 3 has an integrally formed partition trough 301 inside.

[0035] Specifically, through the active sprinkler frame 2 running through the device support 1, clean water can be drawn for intermittent spraying according to the ambient temperature. The principle of water evaporation and heat absorption is used to reduce the local temperature and achieve high temperature resistance. This is also a highly efficient irrigation system with a compact structure and small footprint. It complements the device support 1, sprays water evenly, and improves the seedling raising effect.
