活性制剂对冬小麦光合特性及产量的影响
Effects of new active agents on the growth and yield of winter wheat
摘要
Abstract
The chlorophyll content, photosynthesis and transpiration, water use efficiency, dry matter accumulation and distribution were studied in field experiment, with the aim of determining the effects of multi-functional anti-transpirant (FA) and new active agent (GR) on the growth and grain yield of winter wheat after foliage spraying before the flowering stage. The results indicated that after 17 days, the chlorophyll content and photosynthesis in flag leaves of winter wheat increased by 5.0 % ~ 9.1% and 33.1% ~ 56.7 % compared to those of the control. In FA and GR treatments,the dry matter accumulations in stems and leaves incr sharply eased by 23.5% and 16.0%, respectively. Meanwhile,the spikes dry weight and total dry matter in FA treatment significantly increased by 30.2% and 22.0%. The grain yields increased by 7.1% and 5.1%, respectively, after spraying FA and GR. It was initially considered that due to the increasing of chlorophyll content, photosynthetic capacity, and the effective control and regulation of dry matter partition,the yields of winter wheat were enhanced in biochemical agent treatments.关键词
