摘要
利用专用无纺布进行水稻育苗试验,结果表明:采用无纺布育水稻秧苗在水稻出苗前必须覆盖地膜,可提高前期苗床保温保湿效果,并且在水稻出苗前后根据天气情况及时揭去地膜。无纺布育苗的出苗期比对照晚3～5 d,苗床内地表温度比对照在4:00时低2℃,12:00时低9℃,20:00时低5℃。
The non-woven fabrics were used to raise rice seedling in the experiment.The results showed that plastic film must be covered before seedling in non-woven fabrics to improve temperature and humidity keeping effects in seedbed,and plastic film must be uncovered in time according to weather.In raising rice seedling with non-woven fabrics,seedling stage was 3-5 days later than the control.At 4 o＇clock,12 o＇clock and 20 o＇clock,temperature in seedbed was 2℃,9℃,5℃ lower than the control,respectively.
