摘　　要：为给欧李的栽培生产提供技术指导,以同一品系的3年生欧李为试料,在不同程度的遮光处理下对欧李的坐果率、叶片中叶绿素含量、新梢的生长量、果实生长量、单果质重、单株产量、果实的可溶性固形物含量和pH值进行了试验研究。结果表明:遮光25%后,欧李的坐果率、叶绿素含量、新梢伸长量、单果质重、单株产量和可溶性固形物含量与正常光照下的差异均不显著,而新梢增粗量和pH值与正常光照下的差异显著;遮光50%和遮光75%后,其坐果率、叶片中叶绿素含量、新梢的生长量、果实生长量、单果质量、单株产量、果实的可溶性固形物含量和pH值均显著低于正常光照的,这说明欧李具有一定的耐阴能力,在遮光50%以上的条件下仍能生长良好。由此可知,欧李的种植范围还可以扩大,生产中可将欧李栽植在高大木本植物行间,以提高土地的利用率。In order to provide reference for cultivation and production of Chinese dwarf cherry,taking 3-year-old plants of Chinese dwarf cherry as materials,some indexes were determined under different shading degrees,including rate of fruit setting,chlorophyll content,new shoot increment,and so on.The results showed that under the condition of 25% shading,rate of fruit setting,chlorophyll content,length increment of new shoot,fruit mass,yield per plant and soluble solid content were not significantly different from the values under the condition of normal light,but thickness increment of new shoot and pH value.Under the conditions of 50% and 75% shading,all of the indexes were significantly lower than the values under the condition of normal light.The results indicated that Chinese dwarf cherry had a certain shade-tolerant capability,and still could well grow under the condition of below 50% shading.So cultivation zone of Chinese dwarf cherry could be enlarged,and it could be planted in the lines of high plants for improving land use capability.
