【摘要】 用溶液培养和田间试验的方法研究了氮、磷、钾不同施用量及其配比对芦苇生长发育及品质的影响.结果表明:在溶液培养中,氮、磷、钾分别为160、10、80mg/L时,有利于芦苇实生苗的生长;在当地土壤肥力状况下,氮、磷、钾公顷施用量分别为207kg、15kg、61kg可提高产量23.4%,并提高了芦苇的纤维含量和长度。该配比在部分苇场示范,增产率平均达51.6%,说明高氮、高钾对提高芦苇产量有利。更多还原

【Abstract】 utilized solution culture and field experiment to study the effect of different dose and proportion of N、P and K to reed development and nature.The experiment result shows N、P and K was respectively160?10?80mg /L that benefit seedlings development.Under local fertilizer condition,N、P and K dose was respectively207kg?15kg?61kg can increase yield23.4%and increase the content and length of reed fibre,which was demonstrated in partial reed farms with increasing yield51.6%averagely.So illustrate high N and K is favorable to reed yield.更多还原
