本文分析了甘薯在不同施肥水平下,各生育阶段内碳氮代谢与养分运转的生理过程。讨论了甘薯的叶层结构、净同化率、生物产量、经济产量与叶面积的关系。初步拟出认为适宜的叶面积指标。
In this paper, the physiological processes of carbon and nitrogen metabolism and nutrient turnover in different growth stages of sweet potato under different fertilization levels were analyzed. The relationship between leaf structure, net assimilation rate, biomass yield, economic yield and leaf area of sweet potato was discussed. Initially proposed as appropriate leaf area indicators.
