为了探求柿树需光量及光合强度与呼吸强度的周日变化、光照与结果的关系,以作研究柿树生理基础及栽培技术的依据,我们于1977年8月分别在山东省山东农学院校园、山东泰安县姜家庄大队、孙家沟大队等地,以15—40年生镜面柿、四烘柿为试材,进行了测定与研究,初步得出如下结果: 一、柿的需光量植物的需光特性直接影响到它的生长与发育。其需光量的两个主要指标是光合作用的光补偿点与光饱和点。本试验得知柿的光补偿点为900米烛光,只有夏日最强自然光照的1%;
In order to explore the persimmon light demand and photosynthetic intensity and respiratory intensity of the sun, light and the relationship between the results for the study of persimmon physiological basis and cultivation techniques, we were in August 1977 in Shandong Province, Shandong Agricultural College campus , Tai’an County, Shandong Jiangjiazhuang Brigade, Sunjiagou brigade and other places, with 15-40 years mirror persimmon, persimmon persimmon as the test material for the determination and research, the initial results are as follows: First, the demand for light persimmon plant needs Light properties directly affect its growth and development. The two main indicators of light demand are photosynthesis light compensation point and light saturation point. The test found that persimmon light compensation point of 900 m candlelight, only the summer sun strongest natural light of 1%;
