基肥与密度互作对水稻产量构成因素及产量的影响
|
摘要
采用随机区组法,以三江6号和绥粳18号为试验材料,研究基肥与密度互作对产量构成及产量的影响。结果表明:两个品种基肥与密度处理间在穗数、穗粒数、结实率、千粒重及产量上均存在互作关系,A3B3(20 kg/667 m~2基肥,30cm×12 cm)组合有利于水稻产量的提高,A1B1(12 kg/667 m~2基肥,30 cm×16 cm)组合不利于水稻产量的提高。
Random block method was used to study the effects of base fertilizer and density interaction on yield composition and yield of Sanjiang-6 and Suijing-18. The result indicated that there were interactions between base fertilizer and density treatments in panicle number, grain number per panicle, seed setting rate, 1000-grain weight and yield. A3 B3(20 kg base fertilizer, 30 cm × 12 cm) combination was beneficial to increase rice yield, A1 B1(12 kg base fertilizer, 30 cm × 16 cm) combination was not conducive to increase rice yield.
