中国香稻关键栽培技术初探

通过连续两年的栽培试验和调查发现，中国香稻在孝感市孝南区宜于作中稻和一季晚稻栽培；结实率低是限制该品种发挥增产潜力的主要限制因素。在孝南区的最佳播种期是5月中旬至5月25日；最适宜的栽培密度为1．8万蔸。在栽培中国香稻时，应适当使用氮肥，增施磷钾肥。后期注意保持土壤湿润，同时注意防治病害。

Initial Discussion on the Key Cultivation Technology of Chinese Fragrant Rice

Based on two years trial data,Chinese fragrant rice could be used as middle rice and late rice growing one season in Xiaonan district of Xiaogan city.The main limited factor of increasing yield was fruit rate too low.The optimal seedtime of Chinese fragrant rice was from the middle ten-day period to the 25th of May in Xangan and optimal cultivated density was 18 thousands sockets per 666.7m 2.It was very important that we properly used nitrogenous fertilizer and increasedly used phosphorus and potassium fertilizer,and kept soil wetness in later growth stage when Chinese fragrant rice was cultivated.The pests and diseases of rice must be prevent and cured on time.
