| 摘 要： | 以黔南优2058为材料,通过田间试验研究免耕移栽对杂交水稻生长特性应产量的影响.结果表明,与翻耕移栽相比,免耕移栽水稻成穗率较高,生育后期干物质积累量较大,老化指数和根系氧化力较高,抗衰老能力较强.免耕移栽水稻的有效穗数、结实率和千粒重均比翻耕移栽水稻高,免耕移栽水稻的实收产量为11167.9 kg·hm-2,亦比翻耕高1.6%,但未达到5%的显著差异水平.

| Abstract: | On the condition of field experiments with rice cultivated Qiannanyou2058,the effects of no-tillage and transplanting(NT-RT) on growth properties and yield in hybrid rice were studied.The results showed that compared with conventional tillage and transplanting(CT-RT) rice,the NT-RT rice obtained higher effective spike rate,aging index,root oxidation ability and more dry matter accumulation.The effective panicles number and seed setting and 1000-grain weight of NT-RT rice were higher than those of CT-RT rice... |
