Constant-temperature seed germinator with high germination uniformity

Abstract

The invention discloses a constant-temperature seed germinator with high germination uniformity. The constant-temperature seed germinator comprises a box, wherein a liquid feeding port is formed on the top of the box; a plurality of illuminating lamps are arranged on a top wall of an inner chamber of the box; a rail rod and a screw rod are arranged in the middle of the inner chamber of the box; the screw rod is sleeved with a moving block which is matched with the rail rod; a spraying device is fixedly connected with the bottom of the moving block; a liquid supply box is arranged on the top of the spraying device; a constant-temperature heating device is arranged on the top of the other inner chamber wall of the box; support plates are symmetrically arranged on left and right side walls at the bottom of the inner chamber of the box; a storage plate is arranged at the top ends of the support plates; a germination box is placed on the top of the storage plate. The spraying device of the constant-temperature seed germinator is capable of uniformly spraying the liquid onto the germination box, the outside air enters into the box through an air vent window, sufficient oxygen is filled into the box, the constant-temperature heating device is used for supplying constant temperature to the inner chamber of the box and sufficient illumination is supplied by the illuminating lamps, so that an excellent environment is supplied for the seed germination and the seed emergence rate is greatly increased.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a constant temperature seed germination device with high germination uniformity. Background technique [0002] Mature and dry seeds are in a dormant state when certain external conditions are not obtained. At this time, the embryos in the seeds almost completely stop growing. Once the dormant seeds are released from dormancy and obtain suitable environmental conditions, Embryos in a dormant state become active and begin to grow, a process known as seed germination. The indispensable external conditions for germination are: sufficient water, suitable temperature and sufficient oxygen; when some seeds germinate, light is also a necessary factor. [0003] The seed germination devices in the prior art are all through adding liquid or material to the seeds in a large area. The seed germination effect is good at the center of the bearing plate inside the germination dev...

AI Technical Summary

Problems solved by technology

[0003] The seed germination devices in the prior art all add liquid or feed to the seeds in a large area. The seed germination effect is good at the center of the bearing plate inside the germination device, while the germination of the seeds at the edge of the bearing plate inside the germination device is slow, so that the seeds The germination is uneven, and there will be too much liquid waste. In order to ensure the uniformity of seed germination, sometimes the supply of liquid is increased, which will cause too much liquid in the central area, causing the seeds to fail to germinate normally. and death, thereby reducing the germination rate
