太阳能温床是江苏省沛县唐高林同志发明的,曾获江苏省人民政府科技成果三等奖,是一种经济有效的适用技术,是农业生产上一项新成果,现除在本地推广应用外,还在山东等地推广应用,取得了显著效果,深受广大群众的欢迎。一、温床的特点1.保温性能好,土温高而稳定。太阳能温床能使热空气输送至温床底部,从而提高土壤温度,这是太阳能温床的关键,据1981年1月17日至2月1日测定,营养土下1厘米深处日平均温度为15.1℃,比普通薄膜温床高9.1℃。在早春(三月中、下旬),床内土壤平均温度一般为20℃左右,比普通温床高10℃上下。81年冬季,连续六天雨雪,大气温度降至零下13℃时,床土温度仍保持在14℃以上。2.空间温度高,昼夜温差小。
Solar hotbed was invented by Comrade Tang Gaolin of Peixian County in Jiangsu Province and won the third prize of scientific and technological achievements of Jiangsu Provincial People’s Government. It is a kind of economical and effective applicable technology and a new achievement in agricultural production. , But also in Shandong and other places to promote the use and achieved remarkable results, welcomed by the masses. First, the characteristics of hotbed 1. Insulation performance, high temperature and stability. Solar hotbed allows hot air to be delivered to the bottom of the hotbed to raise soil temperature, which is the key to solar hotbed, as measured from January 17 to February 1, 1981, with a daily average temperature of 1 centimeter below nutrient soils , 9.1 ℃ higher than ordinary film hotbed. In early spring (mid-March, late), the average soil bed temperature is generally about 20 ℃, 10 ℃ higher than the average hotbed up and down. 81 years of winter, rain and snow for six consecutive days, the air temperature dropped to minus 13 ℃, bed soil temperature remained above 14 ℃. 2. Space temperature is high, small temperature difference between day and night.
