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及产量的影响。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11 167.9 kg.hm-2,亦比翻耕高1.6%,但未达到5%的显著差异水平。
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. The average yield of NT-RT rice reached to 11 116.9 kg·hm^-2, and increased by 1.6% compared with CT- RT rice, however, the difference was not up to significant level of 5% between NT - RT and CT - RT.
