摘要
选取诺木洪农场3~5年生枸杞植株为试验材料,利用诺木洪国家基准气候站提供的2023年7月至9月的气象数据,结合试验周期内植株的株高增长情况、生理指标、叶片光合指标、果实产量及部分品质指标,深入分析光热资源对诺木洪地区枸杞的影响,并探讨光合指标与枸杞产量及部分品质指标之间的关系。研究结果表明:随着积温升高,株高增长率和产量也显著提升,同时鲜干比降低,色差增大;光照累积时长的变化与SPAD和N含量的变化同步达到峰值,而H_(2)O含量在日照时长达到最大值时处于最低值;光合指标对产量和部分果实外观品质有显著影响。
The experimental materials consisted of 3-5-year-old goji berry plants from Nuomuhong Farm.Utilizing meteorological data from the Nuomuhong National Benchmark Climate Station for the period from July to September 2023,combined with observations on plant height growth,physiological indicators,leaf photosynthetic indicators,fruit yield,and certain quality indicators during the experimental period,we conducted an in-depth analysis of the effects of light and heat resources on goji berry in Nuomuhong area.Additionally,we explored the relationship between photosynthetic indicators and the yield and quality of goji berry.The study results indicated that with increased accumulated temperature,both plant height growth rate and yield showed significant improvement,while the fresh-to-dry ratio decreased,and color difference increased.The variation in cumulative light duration reached its peak simultaneously with the changes in SPAD and nitrogen content,while H_(2)O content was at its lowest when light duration was at its maximum.Photosynthetic indicators had a significant effect on yield and certain fruit appearance qualities.
