分析大埔县山区杂交水稻的产量构成规律和山区杂交水稻高产与否的前、中、后期生长指标。指出对产量构成的相关关系规律是有效穗数、平均穗总粒数、实粒数与产量成显著或极显著正相关。提出山区杂交水稻平衡高产应根据不同生态环境分类指导，高产途径应该是高产田选用中迟熟大穗多粒型组合，在足穗基础上争大穗；中低产田应以增加有效穗数，走多穗夺高产的途径。不论哪类田增产核心是增加单位面积内有效颖花数。

The form law of production of hybrid rice in mountain areas in Dabu county is analyzed. The growth index in early, middle and last period on whether hybrid rice is high yield or not in the mountain areas is analyzed. The effective panicle number, average total grains and average filled grains per panicle and production are significantly or extremely significantly positive correlated. There is not an only solution to increase production in high yield in balance on hybrid rice in mountain areas, should be provided in classified guidance according to different ecological environment. The solution to increase production should be in combination of middle ripe and late ripe, large panicle and many grains in the high yield field, striving for large panicle on a basis of getting sufficient particles as well, while increasing effective panicle number and obtaining the high yield by making the panicles in unit area abundant in middle and low yield field. The core of increasing the production is to increase the effective number of spikelets per area in which type of field.
