摘　　要：采用随机区组试验(15m2/小区),研究不同施肥处理对藜麦不同物候期农艺性状、生物量、叶绿素和产量的影响。结果表明,氮磷(NP)、氮钾(NK)、磷钾(PK)(N:485.94g、P:585.86g、K:374.98g)处理之间对藜麦的生长和产量均无显著差异(p<5%),但显著高于对照(CK)处理;氮磷钾(NPK)处理对藜麦有显著的肥料效应,其株茎、株高、叶数和产量均有显著增加,藜麦叶片SPAD值在麦穗期和旺长期分别比ck处理增加了63.09%和66.57%,比NP、NK和PK处理下增加了11.47%~22.31%;NPK处理下,藜麦平均生物量(135.47g/株)显著高于CK(79.61g/株),平均产量为862.76g,比CK、NP、NK和PK处理分别高51.54%、36.33%、38.61%和41.07%。因此,合理调节N、P、K肥的用量,提高肥料利用率,可促进藜麦生长,达到增产增收的目的。In order to provide a theoretical basis for fertilization for the growth process of quinoa,the fertilizer efficiency test method of random block(15 m2 plot)experiment is used to study the growth、biomass、chlorophyll and yield of quinoa.The results showed that there was no significant(p<5%)difference in the growth and yield of quinoa between the treatments of NP,NK,PK(N:485.94 g,P:585.86 g;K:374.98 g),but it was significantly higher than CK treatment;NPK treatment had significant(p5%)fertilizer effect on quinoa.The SPAD value of leaf increased by 63.09%and 66.57%respectively in panicle stage and vigorous period than CK treatment,11.47%-22.31%than NP,NK and PK treatment;Under NPK treatment,the average biomass(135.47 g per)of quinoa was significantly(p5%)higher than CK(79.61 g per),the average yield was 862.76 g,it was higher than CK,NP,NK and PK treatment 51.54%,36.33%,38.61%and 41.07%respectively.Therefore,it was necessary to adjust the amount of N,P and K fertilizer reasonably,improve the utilization rate of fertilizer,promote the growth of quinoa,and achieve the purpose of increasing production and income.
