分析苹果产量形成过程中光、热、水的利用指出,10年平均,形成生物学产量利用光能的1.62%,形成经济产量利用0.4%。高产品种相应为2和0.6%,低产品种为1.4和0.28%。同期内在产量形成过程中利用55%的降雨(各年占42—85%)。生物学产量与研究的生态因子间存在着密切的显著相关,成为函数关系。但经济产量与这些因子间无重要联系。就是说生物学产量是植物光合活动的机能,而经济产量数值是不稳定的,它决定于许多多变的因子,总的体现在经济产量上。
Analysis of apple production during the formation of light, heat, water pointed out that the average of 10 years to form a biological yield of 1.62% of the use of light energy, the formation of economic output utilization of 0.4%. The corresponding high-yielding varieties are 2 and 0.6%, while the low-yielding varieties are 1.4 and 0.28%. During the same period, 55% of the rainfall was utilized in the production process (42-85% each year). There is a close and significant correlation between biological yield and ecological factors under study, which becomes a functional relationship. However, there is no important correlation between economic output and these factors. In other words, biological yield is the function of plant photosynthetic activity, and the economic output value is not stable, it is determined by many changing factors, the total reflected in economic output.
