摘　　要：阐述了杂交稻制种节水增效关键技术和节肥高产稳产关键技术及其3项改进措施。即在技术路线上,改主攻穗数的高投入途径为采取穗粒兼顾的节本高产稳产途径;在施肥量上,改"高氮高磷钾"施肥为"适氮高磷钾"施肥;在各次肥料施用比例上,改"前促一轰头"施肥为"稳促"施肥,从而实现杂交稻制种节本增效、高产稳产。Water-saving and fertilizer-saving techniques in hybrid rice seed production and 3 improved measures were discussed. 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 fertilizer promoting into steadily promoting. By all of these, high and stable yield of hybrid rice seed production was obtained.
