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.
