摘　　要：对不同水稻栽培方式群体株高、叶片和穗部性状进行了研究。结果表明,乳苗抛栽群体株高低于手插秧和抛秧,不同栽培方式株高的差异达极显著水平,乳苗抛栽群体上层叶片比较平展,穗型比手插秧方式和抛秧方式小,各形态特征之间的关系比较复杂,不同栽培方式对水稻群体形态特征的影响较大。Plant height, leaf characteristics, panicle characteristics of different rice populations were studied. The results showed that, plant height of rice nursing seedlings scattering （NSS） was lower than that of hand-transplanting （HT） and scattering-transplanting （ST）. There was a very significant difference among plant heights of different planting patterns. The top leaves of NSS were plane and their panicles were smaller than that of HT and ST. The results indicated that complicated correlations among morphological characteristics. Rice population morphological characteristics were obviously affected by planting patterns.
