摘要
为筛选适宜桐城双季稻区种植的早粳稻品种,于2022—2023年开展早粳稻品种比较试验,其中2022年以中早39为对照,选择莲稻2号等10个品种;2023年以早籼310为对照,选择垦稻23等12个品种,对各品种生育期、经济性状和产量水平进行对比评价。结果表明,2022年各参试品种全生育期131~137 d,产量4860.00~7476.00 kg/hm^(2);2023年各参试品种全生育期122~131 d,产量3765.75~6126.90 kg/hm^(2)。其中垦稻23抽穗早,生育期适宜,产量高,抗寒能力强,分蘖早而快,有效穗多及后期转色好;牡丹江30的产量较高,抽穗期适中,株高恰当,有效穗充足,结实率高,千粒重适宜;通35的产量较高,有效穗多,穗型适中,结实率高,千粒重适宜,熟期转色佳,但抽穗期偏迟。上述3个品种可作为研究区的早粳稻品种推广种植,对于提高早稻产量和品质具有重要意义。
To screen suitable early japonica rice varieties for planting in the Tongcheng double season rice area,a comparative experiment of early japonica rice varieties were conducted from 2022 to 2023,in 2022,Zhongzao 39 was selected as the control,and 10 varieties such as Liandao 2 were selected,in 2023,Zaoxian 310 were selected as the control,and 12 varieties such as Kendao 23 were selected,and the growth period,economic traits,and yield levels of each variety were compared and evaluated.The results showed that,in 2022,the whole growth period of each tested varieties was 131-137 days,and the output was 4860.00-7476.00 kg/hm^(2),in 2023,the whole growth period of the tested varieties was 122-131 days,and the yield was 3765.75-6126.90 kg/hm^(2).Kendao 23 had early heading,suitable growth period,high yield,strong cold resistance,early and fast tillering,more effective panicles,and good color change in the later stage.Mudanjiang 30 had a high yield,moderate heading stage,appropriate plant height,sufficient effective panicles,high seed setting rate,and suitable thousand grain weight.Tong 35 had a high yield,multiple effective ears,moderate ear shape,high seed setting rate,suitable thousand grain weight,and good color change at maturity,but the heading stage was relatively late.The above three varieties could be promoted and planted as early rice varieties in the study area,which is of great significance for improving the yield and quality of early rice.
