中文摘要: 1997年进行的小麦喷施多功能防旱剂的试验结果表明,光合作用强度较对照提高14%~28%,气孔阻力较对照提高24%~51%,蒸腾强度降低1%~9%,水分利用效率提高2%~27%,千粒重提高2%~6%,产量增加1.8%~7.1%,说明喷施多功能防旱剂后,对促进小麦生长、降低蒸腾强度、提高产量有一定的作用。
Abstract:By spraying Multi function drought preventing agents onto winter wheat,photosynthesis was increased by 14~28 percent compared with that of the natural plot. Stomata resistance was increased by 24~51 percent. Transpiration was decreased by 1~9 percent. Water use efficiency was increased by 2~27 percent. The weight of 1000 grains of winter wheat and yield were raised by 2~6 and 2~7 percent respectively. These indicate that the multi function drought preventing agents have the function of promoting growth,decreasing transpiration,and raising yield for winter wheat.
