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%。
The spatial distribution of high light efficiency light distribution, yield, quality and benefit of Red Fuji apple and its relationship with light distribution were studied. The distribution threshold of high light efficiency illumination was ascertained. The spatial distribution of high light output, high quality and high efficiency was uniform (1: 1.16: 1.16). The vertical distribution of light threshold was 85%, 65% and 40% respectively. The results showed that reasonable illumination and photosynthetic rate could increase yield, improve appearance quality and increase income of Red Fuji apples, increase yield by 28.5%, increase first grade yield by 15%, reach 98%, increase efficiency by 28.1% Yield 71.5%.
