| 摘 要： | 为充分利用一季中稻地区的光温和农田资源，以超级稻中浙优1号为材料，进行了不同播种期对头季稻及再生稻的产量影响试验。结果表明，一季中稻区种植超级稻中浙优1号蓄留再生稻播种期在3月19日-4月8日均能保障头季稻于8月20日前成熟收割，再生稻于11月上旬黄熟，但以3月19日左右播种的产量最高，两造产量达14197．5kg／ha，可在一季中稻区推广应用。

| Abstract: | In order to make full use of light resources, temperature and field in one-cropping middle rice zone, super rice variety Zhongzheyou 1 was used to study the effects of different seeding dates on the yields of the first cropping and ratoon rice. The results showed that the first cropping of rice variety Zhongzheyou 1 (sown during March,19 to April,8 in one cropping middle zone)could be harvested before August, 20 and ratoon could be harvested in the first ten-day of November. But the yield of super rice was ... |
