摘　　要：茭白是桐乡主要的特色经济作物,为合理利用现有的耕地面积,提高复种指数,筛选出科学高效的栽培模式,以3个茭白品种和1个晚稻品种为试验品种,进行了茭-稻一年二熟新技术模式的研究。结果表明,11月24日定植双季茭白薹管秧苗,第二年茭白返青后追肥3~4次,在5—6月即可采收茭白,7月10日至20日种植上师大19号晚稻,11月即可收割水稻。3个茭白品种均适合茭-稻一年二熟耕作制度,先种植龙茭2号双季茭白再种植上师大19号晚稻时的总产值最高,每667 m^(2)总产值11 248.05元,其中每667 m^(2)茭白产值8 699.65元,每667 m^(2)晚稻产值2 548.4元,是本次试验的最佳组合。Zizania latifolia is the primary cash crop in Tongxiang City.In order to optimise the utilisation of existing arable land,enhance the replanting index and identify a scientific and efficient cultivation mode,three Zizania latifolia and one late rice varieties were selected as experimental varieties to study the new technology model of Zizania latifolia-rice double cropping.The results showed that transplanting double-season Zizania latifolia seedlings on November 24th,applying additional fertilizer 3~4 times after the Zizania latifolia regrow in the second year,allows for harvesting the Zizania latifolia in May and June.Planting Shangshida 19 late rice variety between July 10th and 20th enables harvesting the rice in November.Three Zizania latifolia varieties were identified as suitable for Zizania latifolia-rice double cropping system.It is crucial to plant the double-season Zizania latifolia variety Longjiao 2 and late rice variety Shangshida 19 as test varieties initially to obtain the highest total output value,with a total output value of 11248.05 yuan per 667 m^(2).The output value of Zizania latifolia was 8699.65 yuan per 667 m^(2),while that of late rice was 2548.4 yuan per 667 m^(2),representing the best combinations in the experiment.
