| 内容記述 | We used hydroponic culture and performed a leaf petiole sap test to study the influence of low phosphorus (P) availability on the growth, nutrient uptake, and dry matter production of cucumber (Cucumis sativus L.). Plants were grown by the deep-flow technique for 64 days after transplanting, using nutrient solutions with different P levels (0.2, 0.4, 0.8, 1.4, or 2.2 meq L^–1). The P concentration in the nutrient solution was strongly and significantly correlated with P absorption (r = 0.982) and total dry matter (r = 0.915). There was a linear correlation between the P level in the nutrient solution and P absorption. However, the increase in total dry matter in response to the P level in the nutrient solution exhibited a peak, with no additional increase of total dry matter at a P concentration of 1.4 meq L^–1 or more. For plants grown with a low P level ( ≤ 0.8 meq L^–1), dry matter production was significantly reduced compared with growth in other treatments because of decreased leaf area development and decreased nutrient uptake. There was a strong and significant correlation (r = 0.946) between the P concentrations in the leaf petiole sap (PPS) and in the leaves (PL) : PL = 3.134 × ln(PPS) - 6.267 PPS increased linearly with increasing P level in the nutrient solution. These results suggest that to sustain dry matter production, the P concentrations in the nutrient solution and the leaf petiole sap should be maintained at ≥ 0.8 meq L–1 and ≥ 90μL L^–1, respectively. However, at a P concentration in the nutrient solution higher than 1.4 meq L^–1, the P fertilization efficiency decreases. | |||||||||||||||||
