Abstract: Growth dynamic and nutrient uptake of common bean (Phaseolus vulgaris L.) cultivar Liyun 2 were studied in this research to clarify the nutrient uptake over the growth period so as to provide a basis for more scientific nutrient management. Field experiments were carried out in Lishui City, Zhejiang Province in 2016. The agronomic management measures in the production of common beans were consistent with local farmers' practice. In seedling stage, stretch tendril stage, flowering stage, pod setting stage and harvest stage, plant samples were taken to determine and analyze the dry material accumulation and nutrient element content. Results indicated that the dry material accumulation of common bean showed an increasing trend over the growth period, and the harvest stage had the largest accumulation of dry material, 2 304.6 kg·hm-2. The nutrient demands of common bean in different growth stages were showed as follows: harvest stage>pod setting stage>stretch tendril stage>seedling stage and flowering stage. During the common beans production, the nutrient uptake ratio for N, P, K was 1.0∶0.4∶1.0, and nearly 79.0% of all N, P, K uptake were redistributed to economic yield, respectively. The nutrient requirement for N, P and K at the yield level of 30 000 kg·hm-2 were N 155-181 kg·hm-2, P2O5 82-103 kg·hm-2, K2O 136-156 kg·hm-2, which were evaluated according to the yield level, nutrient concentration and N/P/K use efficiency. This study can provide a basis for the nutrient management in common bean production and the control of environmental risk caused by fertilizer over application.
