摘要
为比较稻豆复种模式较常规双季稻种植模式的优势,于2022年在杭州富阳设置早稻-晚稻、春大豆-晚稻与早稻-秋大豆3种种植模式开展大田试验。结果表明:在相同施肥量与大田管理下,春大豆-晚稻种植模式经济效益最高,较双季稻模式提升63.3%,主要得益于晚稻产量的提高及春大豆的经济效益高于早稻;春大豆-晚稻模式下晚稻干物质量较双季稻模式晚稻增加206.3%;早稻-秋大豆种植模式经济效益较双季稻模式提高51.0%,两种模式下早稻产量无显著差异,但秋大豆的经济效益高于双季晚稻。稻豆复种可保障水稻正常生长发育,并提高作物总产量和经济效益,具有较大推广应用价值。
In order to clarify the effect of Rice-Soybean multiple cropping on rice growth and yield compared with conventional double-cropping rice planting mode,a field experiment was carried out in Fuyang,Hangzhou in 2022.Three planting modes were set up:Early Rice-Late Rice,Spring Soybean-Late Rice,Early Rice-Autumn Soybean.Results showed that under the same fertilization and field management,Spring Soybean-Late Rice model had the highest economic efficiency,63.3% higher than the double-cropping rice planting model,mainly due to the increase of late rice yield and higher economic efficiency of spring soybean.Spring Soybean-Late Rice model increased 206.3% dry matter in late rice compared with double cropping rice model.Compared with the double cropping rice model,the Early Rice-Autumn Soybean model increased 51.0%economic efficiency.There was no significant difference in early rice yield between the two models,but autumn soybean planting efficiency was higher than the continuous cropping late rice.This experiment result showed that Rice-Soybean multiple cropping can guarantee the rice growth and increase crop yield,which had great promotion and application value.
