| Abstract: | Water-saving and fertilizer-saving techniques in hybrid rice seed production and 3 improved measures were dis-cussed.Those were,taking account of ears and grains instead of main attacking the ears;advocating suitable nitrogen and high level of phosphorus and potassium instead of high level of nitrogen,phosphorus and potassium;changing strongly fertil-izer promoting into steadily promoting.By all of these,high and stable yield of hybrid rice seed production was obtained. |
