【摘要】 利用开顶式熏气装置,对水稻和青菜进行长时间的HF暴露试验。通过在熏气过程中对叶片电导率、含氟量和脯氨酸的分析比较,以及在熏气结束后对水稻穗数、千粒重和青菜鲜重的生物量统计测定,讨论和评价了HF对该作物产量的影响。更多还原

【Abstract】 The effects of HF on yields of rice and green vegetables were evaluated using open-top field chambers. The leaf conductivity and the contents of fluoride and proline in leaves were measured during the process of fumigation. The ear number and grain weight of the rice and the fresh weight of the vegetables were determined for tested plants.更多还原
