摘要
采用二次通用旋转组合设计研究了不同施氮、钾量及种植密度对秋茭、夏茭的有效分蘖数、单茭重及产量的影响。结果表明,对秋茭施氮量16~18kg/667m2、施钾量17~18kg/667m2、种植密度0.7~0.8m2/穴最为适宜;对夏茭施氮量控制在9~10kg/667m2,增施钾肥,种植密度维持在0.7~0.8m2/穴较为适宜。
By means of 3 factors-5 levels universal rotational regression combination design, the effective tillering number, single stem weight and yield of water bamboo were studied. The results show that for the first harvest season(autumn), it is very applicable that using amount of the nitrogen fertilizer is 16-18 kg/667 m2, the potassium fertilize is 17-18 kg/667 m2 and the density is 0.7-0.8 m2/cluster. For the second harvest season(summer), it is more applicable that the nitrogen fertilize is 9-10 kg/667 m2, and the potassium fertilize must be increased.
