| 摘 要： | 以典型的广适性杂交籼稻品种天优华占为对照,以21个不同熟期类型的代表性粳稻品种为供试材料,开展了播种期试验。结果表明:在5月30日或6月19日播种的条件下,春优58、甬优8号、常优1号、秀水63均表现出生育期适中、分蘖能力较强、产量高,适合在金华地区种植;在所有供试品种中,以春优58的产量为最高,达9.333 t/hm2,其最适合在金华地区作为单季稻或双季连晚种植推广。

| Abstract: | Based on 21 tested materials which are representative japonica rice varieties with various maturities,taking the typical widely-adaptable indica hybrid rice variety Tianyouhuazhan as the control,the experiment was conducted to select varieties and investigate the optimum sowing date.The results showed that the varieties of Chunyou 58,Yongyou 8,Changyou 1,and Xiushui 63 had better growth period,stronger tillering ability and higher yield than the control under May 30th or June 19th seeding-time treatments.Thus,they were suitable to plant in Jinhua area.In all tested materials,it was found that Chunyou 58,which had the highest yield of 9.333 t/hm2,was most suitable for extension as single cropping rice or continuous double cropping late rice in Jinhua area. |
