The Design And Application Of Efficient Heating Device For Floating Nursery

摘要

Considering the relative large heat capacity of water, this study intends to assess the application of heating blanket as a homoiothermal heating source to heat water in the floating nursery pond. In order to minimize the unfavorable effects of low temperature on the growth of seeds, this study tries to develop a comprehensive set of float breeding technology that consumes less energy. The results indicate that an improved high-efficiency heating blanket has a higher heating ability and heat-insulating property. With proper supporting technology, the system is expected to reduce the relative temperature difference between day and night, and the influence of low temperature on the relative temperature in greenhouse, shorten the time for float breeding by about 10 to 15 days, improve the quality of tobacco seeds, increase the strong seedling rate by 3% and ultimately save energy and cost.
