摘要: 试验通过氮、磷、钾肥配比,在大田生产条件下研究配合施肥对狗牙根种子生产的影响,结果表明:(1)配合施肥对狗牙根枝条数和生殖枝数有显著影响,施肥后狗牙根的枝条数和生殖枝数分别比对照提高31.20;~51.78;和54.54;~98.21;;(2)配合施肥对狗牙根种子产量构成因子影响显著,配比100 kg/hm2N、80 kg/hm2P2O5、80或160 kg/hm2 K2O能显著增加小穗数、种子数,提高结实率和千粒重;(3)配合施肥可以显著提高狗牙根种子产量,配比100 kg/hm2 N、80 kg/hm2 P2O5、80或160 kg/hm2K2O,其种子产量分别比对照提高300 kg/hm2、264 kg/hm2.
