摘要
对红富士苹果高光效光照分布特性、产量、品质和效益的空间分布及其与光照分布的关系进行了研究。探明了高光效光照分布阀值、高产、高品质、高效益空间分布为均匀型(1∶1.16∶1.16),其光照阀值垂直分布分别为85%、65%和40%。该研究结果表明,合理的光照分布和高光合速率对红富士苹果增产、外观品质改善和增收效果显著,可增产28.5%,一级品率提高15%,达98%以上,增效28.1%,收益率达71.5%。
Studyed on canopy light distribution charactess relationship between space distribution of yield,quality and economic effect in high light efficieucy red Fuji apple,Researched high light listribution threshoed ,The space distribution of high yield,high quality and high economic effect was unform type,light thresholds at vertical were respectiudy 85%,65%and 40%.the resutt indicated that rational light distribution and high photosynthesis speed rate had remarrable effect on increasing yield ,inproving gualily and euhancing income in red Fuji apple.yield incriasing was 28.5%,the best quality rate was enhanced 13%,economic effect increasing was 28.1%,Profit rate reached 71.5%.
