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。 The effects of N, P and K nutrients on the biomass of Peganum harmala in Xinjiang were studied to provide a scientific basis for scientific application of Peganum harmala in Xinjiang. Taking Peganum harmala from Pishan County, Xinjiang as the research data, the experiment design was to process the three elements of N, P and K five times for four times to determine the demand regularity of N, P and K. From the perspective of fertilizer supply, the biomass of Peganum harmala decreases with the increase of nitrogen application rate, and the highest reduction rate reached 68.4%. The increase of P fertilizer application showed a gradual increase of biomass, which increased by 42.9% compared with the control. However, there was some special demand for potash fertilizer, which increased first and then decreased, and the increase in treatment Ⅲ was 57.9% higher than that of the control. In Pisha County, Xinjiang, the use of nitrogen fertilizers during the seedling stage of Peganum harmala did not increase yield, and the demand for phosphate fertilizer was almost linear. The demand for potash fertilizer first increased and then decreased.
