马铃薯的产量与其在生长季中叶片截获的太阳辐射量有直接关系。因而,产量受可利用的太阳辐射和叶表面生长两者的共同影响。叶片的生长则受到气候、栽培技术、种薯质量以及种薯的生理状况等众多因子的影响。上述这些因素都很重要,只不过种植者尚不能完全控制而已。因此应最有效地运用所能掌握的栽培技术和种薯的生理状况等项措施。本文旨在阐 The yield of potato is directly related to the amount of solar radiation intercepted by the leaves during the growing season. Thus, the yield is influenced by both available solar radiation and leaf surface growth. The growth of leaves is affected by many factors such as climate, cultivation techniques, quality of seed and physiological status of seed. All these factors are important, except that the grower can not yet fully control it. Therefore, we should make the most effective use of the cultivation techniques we can master and the physiological conditions of seed potatoes and other measures. This article aims to illustrate
