例句与用法
- Abstract : spraying chemical controlling matter ( drought - resistant agent ) on wheat blade in medium - late growth period . we found it influenced transpiration rate , water - retaining capacity , containing water content of dry weight , seeping conductive rate , chlorphyll content and so on in different degree , and improved the moisture content stage of wheat , reduced the seeping of electrolyte , have an obvious effect on delaying decrepit and increasing production
文摘:小麦生育中后期叶面喷施化学调控物质(抗旱剂) ，对蒸腾速率、保水力、干重含水量、外渗电导率和叶绿素含量等均有不同程度的影响，明显地改善了小麦的水分状况，降低了电解质的外渗率，有明显的保绿延缓衰老的作用，增产效果显著。 - The changes of leaf water potential , water deficiency , water - holding ability under drought stress conditions were measured . the water parameters were calculated by using pressure - volume technique , also the abilities of maintaining turgor and adjusting osmotic potential of the four species were comprehensively evaluated . the effects of drought stress on photosynthesis , transpiration and water use efficiency were studied
