摘要
By planting rice in big vats, the ecology effects on rice root system and plant irrigated with the Yellow River water and well water were investigated. The results are shown as the follows: Average root length, root number and root weight of all the treatments of rice irrigated with the Yellow River water are more or better than those of the rice irrigated with well water. Plant height, tiller number, leaf number, 1000 grain weight, grain weight per plant, grain number per spike of rice irrigated with the Yellow River water not only has good effect on growth and development of rice root system, but also is good to plant. Among different rice treatments irrigated with the Yellow River water, treatment Ⅰ(irrigation with the Yellow River water in all development stages), Ⅲ(irrigation with the Yellow River water in tillering stage) and Ⅵ(irrigation with the Yellow River water in tillering stage and heading stage) are more benefiting than other treatments.
