研究氮、磷、钾养分对1a生新疆骆驼蓬生物量的影响,为新疆骆驼蓬科学施肥提供科学依据。以新疆皮山县骆驼蓬为研究资料,试验设计为氮磷钾3要素5个处理4次重复,确定骆驼蓬氮磷钾需求规律。从供肥强度来看,随着氮肥施用量的增加,骆驼蓬的生物量有降低的趋势,其降低率最高时可达68.4%。磷肥料施用量的增加其生物量有逐渐增加的趋势,比对照增加42.9%。但对钾肥的需求有些特别,即先增加后降低,在处理Ⅲ的增加比对照的生物量高57.9%。新疆皮山县1a生骆驼蓬苗期使用氮肥没有增产效果,对磷肥的需求几乎是直线关系,对钾肥的需求是先增加后降低。

To confirm the effect of nutrition,as Nitrogen,Phosphor and Potassium,on the Biomass of annual plant Peganum harmala and provide scientific data for fertilization method,the Peganum harmala from Pishan County was researched by pot experiment with 3 factors,5 treatments and 4 repeats.The biomass of Peganum harmala declined following the increasing of Nitrogen fertilizer,the maximum declining ratio reached to 68.4% relative to CK;The more Phosphor fertilizer,the more biomass of Peganum harmala,the maximum increasing ratio reached to 42.9% relative to CK;the need for Potassium is special,the biomass increased first and decreased later.the maximum increasing ratio reached to 57.9% relative to CK in treatment 3;the nitrogen hasn＇t effect on increasing production,while the phosphor is linear with the production.Potassium fertilizer increases the production of Peganum harmala seedlings.
