摘要:

为了探讨不同浓度萘污染水的灌溉对水稻生长发育及稻米安全性的影响,以水稻品系哈04-34为材料,采用盆栽试验,在人工气候箱内模拟水稻生长环境,测定哈04-34的成活率、产量及其构成因子和残留。结果表明,不同浓度萘处理均能降低秧苗株高,减少秧苗叶片数,但能增加秧苗的根数量,抑制水稻的生长发育,延迟抽穗、延缓抽穗进程、延迟成熟,并且随处理浓度的增大这种变化趋势更明显。随着萘处理浓度的增加,其最终产量下降愈明显,主要表现为每穴穗数和每穗粒数的下降。用萘污染水灌溉的水稻,只要能生长并成熟,其植株和籽粒中均不能检测出萘的残留。

Abstract:

In order to exploring effect of irrigation by contaminated water of naphthaline on rice growth and food security of rice, the trail was carried on by potted experiment in climate cabinate using rice variety Ha04-34. The results indicated that the effect of irrigated rice by contaminated water of naphthaline were depressing plant height of seedling, reducing leaves, increasing root number, delaying heading and delaying maturity. The tendency was evident along with concentration increasing, and yield declining evident along with increasing concentration, the main expression was declining panicle number per hill and grains number per ear. It had not detected naphthaline residue in seed and plant only the rice could to maturity.
