摘　　要：研究了不同栽培模式对水稻产量及农艺性状的影响。结果表明:两个品种中,均以旱作覆膜栽培(HF)产量最高,与水作覆膜栽培(SF)、旱作不覆膜栽培(HBF)、常规栽培(CK)的差异达显著水平。超级杂交稻组合88S/1128不同栽培模式产量从高至低的顺序为:HF>SF>HBF>CK。优质常规稻湘晚籼17号产量从高至低的顺序为:HF>HBF>SF>CK。有效穗数、结实率和千粒重增加是HF产量高的主要因素;两个品种均表现HF干物质积累、单株分蘖数、叶面积指数和SPAD显著高于CK、SF和HBF,但HF、SF和HBF株高不如CK。This study aimed to reveal the effects of different cultivation modes on production and agronomic traits of rice. The results showed that： 1 ）The highest yield of both rice species were under film mulching cultivation in glebe （HF）, which compared with film mulching cultivation in paddy field （SF）, dry farming cultivation （HBF） and conventional cultivation （CK）, the difference reached significant level. The yield sequence of super hybrid rice combination 88S/1128 under different cultivation modes was HF〉SF〉HBF〉CK. The yield sequence of elite inbred rice Xiangwanxian 17 was HF〉HBF〉SF〉CK. 2）The main factor of high-yield rice under HF could attribute to effective panicle number, seedsetting percent and 1 000-grains weight were increased. The dry-matter accumulation, tillering number per plant, leaf area index and SPAD of both rice species under HF were significantly higher than which under CK, SF and HBF, but plant height under HF, SF and HBF were lower than which under CK.
