Automatic seed soaking pregermination device

Abstract

The invention discloses an automatic seed soaking pregermination device which comprises a seed soaking pregermination tank (1) and a control device (2); wherein, the bottom of the seed soaking pregermination tank (1) is provided with a water drain valve, and the seed soaking pregermination tank (1) respectively controls an oxygenation device, a heating device and a cooling device by the control device (2); the oxygenation device is communicated with an oxygenation pipeline arranged at the bottom of the seed soaking pregermination tank (1) through a gas pipeline (9); the heating device includesa sterilizing heating device and a heat insulating heating device, and the sterilizing heating device is communicated with the heat insulating heating device through a steam conduit and then communicated with the seed soaking pregermination tank (1); the cooling device is communicated with the upper part and the lower part of the seed soaking pregermination tank (1) through a low temperature water pipeline (4), so as to form a low temperature water circulation system together with the interior of the seed soaking pregermination tank (1). The invention has the advantages of controllable moisture, temperature, oxygen and illumination, high automation control degree, stable quality of presprouting of seeds and the like, and is especially suitable for the batch production of seed soaking pregermination of small size seeds having small volume and light weight of tobacco, grazing, ornamental grasses, milk vetch, etc.

Description

Technical field: [0001] The invention belongs to the technical field of seed production, in particular to a plant seed soaking and accelerating germination device, in particular to an automatic seed soaking and accelerating germination device suitable for small and light seeds such as tobacco, grass, ornamental grass and milk vetch. Background technique: [0002] In agriculture, forestry and horticultural planting, seeds play an important role. The survival rate of seed emergence and the quality of seedlings formed are closely related to the cost and income of production. Generally, in cold and cool areas that are not suitable for seed germination, the seeds are first germinated and then planted. With the development of modern agricultural technology, higher requirements are put forward for the survival and seedling emergence of seeds. Neat and uniform emergence of seeds is more suitable for large-scale planting. Therefore, the seed germination technology is also developing...
