坡缕石对匙叶翼首草生长、产量和品质的影响

试验采用田间单因素随机区组设计,研究了加施破缕石0、750、1500、2250和3000 kg hm-2五个处理对匙叶翼首草产量及品质的影响。结果表明:缕石在750~3000 kg hm-2施用量下,均能提高匙叶翼首草的产量和品质,且产量随着坡缕石的增加而增加;加坡缕石为3000 kg hm-2时的产量最高较对照极显著增产26.56%(P<0.01),品质也最优;在匙叶翼首草栽培中科学合理的将N、P和K肥料与破缕石配施是提高其产量和品质的一个重要的农艺措施之一。

Effects of Playgoskite on Growth,Yield and Quality of Pterocephalus hookeri(C.B.Clarke) Diels

The single factor randomized blocks design was adopted in the experiment,and the effects of Playgoskite at five different rates of 0,750,1500,2250 and 3000 kg hm-2 were studied on the yield and quality of Pterocephalus hookeri(C.B.Clarke) Diels.Results showed that playgoskite at rates of 750-3000 kg hm-2 could enhance the yield and quality of Pterocephalus hookeri(C.B.Clarke) Diels,whose yield increased along with the increase of Playgoskite.The yield was the highest at the rate of 3000kg hm-2 playgoskite and increased 26.56%(P < 0.01)compared to the control,and the quality was also the best.It is one of important agronomic measures to increase the yield and quality in the cultivation of Pterocephalus hookeri(C.B.Clarke) Diels by the way of scientific and rational combined application of N,P and K fertilizer with Playgoskite.
