| 中文摘要: |
| 通过田间试验，在冬小麦开花前叶面喷施多功能抗蒸腾剂（FA）和自主研发的多糖类活性制剂（GR），比较研究其对冬小麦叶绿素含量、光合蒸腾特性、干物质积累与分配、水分利用及产量的影响。结果表明，喷施制剂17 d后，冬小麦旗叶总叶绿素含量和光合速率较对照增加了5.0%～9.1%和33.1%～56.7%；FA和GR促使收获期小麦茎叶干物质重显著提高了23.5%和16.0%，同时，FA使冬小麦穗干重和总干物质累积量也显著增加了30.2%和22.0%；喷施FA和GR后，小麦产量比对照提高了7.1%和5.1%。分析认为增产与两种生化制剂促进冬小麦叶绿素合成，提高光合潜能，以及有效调控植株体内干物质分配有关。 |
| 英文摘要: |
| 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%, respective
ly, 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. |
