本文阐述利用地热作热源,进行人工气候温室花果木扦插快速育苗工程研究。经三年乡试验表明:温室结构以拱型镀锌钢管大棚使用性能好;苗床宜以细砂作基质并采用地下铺设镀锌钢管通地热水提高地温方式。试验采用自行研制的简易电子调节器温控仪控温;用连续可调式定时加湿控制器或分档可调式定时加湿控制器控湿以及一套扦插花果木育苗技术工艺规程,可使苗床5～10cm 深处的地温保持在25±3℃;相对湿度达85%.在此环境条件下,可缩短成苗期1/3,苗木发根率达90%以上。从而实现了打破季节和地域限制,排除气候干扰,常年进行花果木扦插育苗,具有显著经济效益。
This article describes the use of geothermal as a heat source for artificial climate greenhouse fruits and trees cuttings quickly breeding project. After three years of rural experiments show that: the greenhouse structure to arched galvanized steel pipe greenhouse performance; seedbed should be fine sand as a matrix and the use of underground galvanized steel pipe through the hot water to increase ground temperature way. Test using a simple electronic regulator developed by the temperature controller temperature control; with a continuously adjustable timing humidifier or sub-file adjustable timing humidifier control humidity and a set of cuttings flower seedling nursery technical procedures, seedbed 5 ~ Under 10 cm depth, the ground temperature is kept at 25 ± 3 ℃ and the relative humidity is 85%. Under this environmental condition, the seedling stage can be shortened by 1/3 and the hairiness rate by 90%. In order to achieve the breaking the seasonal and geographical restrictions, eliminate the interference of climate, perennial fruit tree cuttings, with significant economic benefits.
