| 摘 要： | 为了探明新高产栽培模式的增产效果和对农艺性状的影响,对9个水稻材料在两种栽培模式下的产量和主要农艺性状进行了比较研究。结果表明：新栽培模式增产效果显著,单位面积有效穗数极显著增加,结实率显著下降,分蘖初期、分蘖盛期提前,生育期有缩短的趋势,但不同水稻材料的以上变化情况各异。

| Abstract: | The grain yields and main agronomic traits of 9 rice cultivars under the new cultivation practice were compared with those of the conventional cultivation practice . The results showed that the number of panicles per square metre under the new cultivation practice was significantly higher than that under the conventional cultivation practice; and compared with the conventional cultivation practice , rice obtained higher grain yield under the new cultivation practice; the seed setting of rice under the new cultivation was lower than that under the conventional cultivation practice. In addition , under the new cultivation practice, the first and middle stages of rice tillering shifted to earlier dates, and the growth duration shortened. |
