摘要: 为揭示不同播期对浙江省常规晚粳稻品种稻米品质的影响,选取了16个浙江省常规晚粳稻代表品种为试验材料,分别在2013年5月29日、6月28日和7月13日播种。结果表明:大部分品种6月28日播种糙米率、精米率、整精米率和胶稠度最高,直链淀粉含量随播期推迟呈增加趋势,胶稠度和赖氨酸含量随播期推迟呈先增后减的趋势。总体来看,适当延迟播种有助于提高稻米品质。

Abstract:  In order to reveal the effects of different seeding dates on rice quality of conventional photosensitive japonica rice varieties in Zhejiang Province, 16 conventional photosensitive japonica rice varieties were used as materials and seeded on 29th May, 28th June, 13th July in 2013. The results showed that the optimum seeding time for brown rice rate, milled rice rate, head rice rate and gel consistency of most varieties was 28th June; Amylose content increased with the postpone of sowing date, Gel consistency and amino acid content firstly rised then declined. In general, late sowing could get better quality.
