分析了不同肥力水平条件下水稻品种分蘖特性对产量的影响．结果表明，１）穗数型品种分蘖力强，高肥栽培时单茎增多、叶面积增大、茎秆细弱、倒伏、结实率降低，不适于高产再高产的要求；２）高肥栽培时，分蘖力偏弱但有效分蘖期长，在较长分蘖期内逐渐产生分蘖的品种类型，可协调穗数、穗粒数和结实率的矛盾，从而获得高产；３）具有矮秆、中等分蘖能力、有效分蘖期长、有效分蘖率高、叶长而直立的穗重型品种，可协调高肥栽培时群体和个体的矛盾，有望实现超高产．
The effects of tillering characteristics on yield of rice cultivars under different fertility levels were analyzed. The results showed that: 1) Spike number of spike type was strong, tillering ability was higher in high-yielding cultivation, the number of single stem increased, the area of leaf increased, the stem was weak, lodging and seed setting rate decreased, which was not suitable for the requirement of high yield and high yield; , Tillering ability is weak but effective tillering stage is long, and tillering stage is gradually produced in longer tillering stage, which can coordinate the contradiction between ear number, ear grain number and seed setting rate to obtain high yield; 3) With dwarf, medium tiller Ability, effective tillering period, effective tillering rate, leaf length and erect panicle varieties can coordinate the contradiction between groups and individuals in high-fat cultivation, is expected to achieve ultra-high yield.
