| 摘 要： | 山东是马铃薯二季作地区，原来具有一定生产规模和基础，近年生产发展很快，每年收获季节大量马铃薯销往省内外，甚至还有相当数量马铃薯返销东北。目前提高马铃薯种植和产量已是当务之急。研究马铃薯光合生产力是提高产量的基础，本文对鲁南生产条件下的马铃薯光合作用测定结果予以探讨。

| Abstract: | Measurements of the photosynthetic rate of two potato cultivars in the field have shown that there are differences between the cultivars,while both of their curves of photosynthetic diurnal variation of potato leaf had two pesks with an obvious midday depression .Different leaves at the same plant have different photosynthentic rates and one leaf under the different conditions has different photosynthentic rates as biological character of the cultivar,intensity of light and soil relative moisture,affected the single leaf and canopy photosynthesis of potato grown in the field.Apart from light intensity,soil relative moisture and other fact ors,the effective way to increase the yield is to search appropriate plant density and their appropriate canopy construction in the field. |
