Combined-type seedling culture aperture disk of photinia serrulata

Abstract

The invention relates to a combined-type seedling culture aperture disk of photinia serrulata, which mainly comprises a rectangular aperture disk frame, round small aperture disks and an aperture disk cover, wherein the small aperture disks are regularly disposed on the aperture disk frame, the small aperture disk comprises a growth aperture, a matched groove disposed around a circle on the upper end of the growth aperture and an aperture disk plate; and the growth aperture and the aperture disk plate are integrated. The aperture disk cover comprises a cover plate and a sowing hole layer, wherein the cover plate comprises a flat plate and a fixation plate 1, the plat plate is leaf-shaped, the cover plate is connected to the matched groove in the small aperture disk through interference fitting by the fixation plate 1, the sowing hole layer and the cover plate are mutually connected and can be rotated relatively, and positions of sowing holes are corresponding with the growth apertures. By installing the aperture disk cover on the small aperture disk, the combined-type seedling culture aperture disk of the photinia serrulata provided by the invention can fix sowing positions in the center of the growth apertures. After sowing, the sowing hole layer is rotated till the holes are shielded by the cover plate. By the design, root damage caused by frozen soil can be prevented in cold weathers, and anti-season cultivation can even be realized.

Description

technical field [0001] The invention relates to the field of plant seedling raising, in particular to a combined seedling raising tray for Photinia fruticosa. technical background [0002] As a new technology for specialized cultivation and production of commercial seedlings in plug trays, seedling cultivation carriers are mostly light loose substrates with good water and fertilizer retention properties, such as peat, vermiculite, crushed fruit chips, organic humus, etc. One or more Therefore, the amount of raw materials can be reduced to meet the nutrient and water for seedlings, and light and simple seedlings can be implemented; precision sowing in the holes of the plug trays can realize one seed for one seedling, which greatly saves the use of seeds; it also saves seedlings. Intensify and factoryize management. At the same time, the labor intensity is reduced during transplanting, which is beneficial to mechanized operations. It has the characteristics of being suitable...

Problems solved by technology

Among them, the sowing process is a key step in seedling cultivation, and it is also the most important link. Whether it is mechanical sowing or manual sowing, it is necessary to strive for the seeds to fall in the middle of the hole. , usually covered with plastic film, this method is easy to cause pollution, and the cost of laying plastic film is relatively high
