为筛选适宜湘东地区机插栽培的双晚品种,以12个水稻品种为材料,在醴陵市泗汾镇开展了双晚机插品种筛选试验,考察了秧苗素质、生育期、分蘖动态、经济性状和产量等指标。结果表明:H优518、岳优518、五优15、五优308和盛泰优9712生育期适中、抗性强、成熟好、产量较高,可作双晚机插栽培;中早39、荣优233全生育期短,生物产量低,作双晚机插栽培难以获得高产;深优9586和桃优香占未能在安全齐穗期(9月15日)前齐穗,作双晚机插栽培存在一定风险;岳优2115、五优369和岳优3700在某一性状指标有优势,但单产相对偏低,能否作双晚机插栽培有待进一步验证。
In order to screen double-breed varieties suitable for machine-mediated cultivation in the eastern part of Hunan Province, 12 rice varieties were used as materials to screen double-inserted varieties in Sifen Town, Liling City. The effects of seedling quality, growth period, tillering dynamics and economy Traits and yield and other indicators. The results showed that H You 518, Yueyou 518, Wuyou 15, Wuyou 308 and Shing Taiyou 9712 had moderate growth period, strong resistance, good maturity and high yield, You 233 had short growth period and low biological yield. It was difficult to obtain high yield for double cropping cultivation. Shenyou 9586 and Tao Youxiang accounted for the failure to get a full double crop before the safe heading date (September 15) There was a certain risk in planting and cultivating. Yueyou 2115, Wuyou 369 and Yueyou 3700 had the advantage in one trait index, but the yield per hectare was relatively low.
