| 摘 要： | 以Y两优9918和晶两优华占2个水稻品种为试验材料,研究了不同水稻品种进行中稻-再生稻高产栽培时头季稻、再生稻的生育期、产量和经济效益的变化。结果表明:在中稻-再生稻高产栽培模式下,2个水稻品种水稻生育期均无明显差异;头季稻产量以Y两优9918较高,达545.88 kg/667m~2;再生季水稻产量以晶两优华占较高,达254.53 kg/667m~2。两季水稻,以Y两优9918的经济效益较高,为910.37元/667m~2。总的来说,选择Y两优9918水稻品种开展中稻-再生稻栽培模式能获得较高的经济效益,具有一定的应用前景。

| Abstract: | The growth period, grain yield and economic benefit of rice were affected by different planting patterns. Effects of different planting patterns on the growth period, grain yield and economic benefit of mid-season and ratoon rice were tested by using two rice varieties Yliangyou 9918 and Jingliangyouhuazhan as materials in this study. The result showed that there was no significant difference in the growth period between the two rice varieties. The Yliangyou 9918 had higher grain yield at 8188.20 kg/hm2 in the mid-season rice (first crop), but the Jingliangyouhuazhan got higher grain yield at 3817.95 kg/hm2 in the ratoon rice (second crop). And the Yliangyou 9918 had the higher economic benefit at 13655.55 yuan/hm2(RMB) by the mid-season and ratoon rice planting pattern. So the Yliangyou 9918 used as the mid-season and ratoon rice would be of a certain application prospect. |
