摘  要：
银川平原设施内多注重氮肥的投入,对磷肥的投入较少,以银川设施内广泛种植的"长剑"辣椒为研究对象,设定磷肥的不同用量试验,分析了磷肥对辣椒生长、产量及经济效益的影响,确定最佳磷肥施用量。结果表明:初果期前增施磷肥能显著促进辣椒株高增长;适宜的低磷投入能促使辣椒植株健壮;75~225kg·hm~(-2)P_2O_5用量能促进冠幅显著增加,更高则产生反作用;磷肥用量与辣椒产量表现为典型的抛物线式,当P_2O_5用量低于225kg·hm~(-2)时,随磷肥用量的增加,辣椒产量增加,但进一步增加的磷肥用量导致产量下降。该地区最高产量P_2O_5施用量为211.64kg·hm~(-2),最大经济效益P_2O_5用量为187.14kg·hm~(-2)。

摘  要：
People usually pay more attention to nitrogen fertilizer input but less investment in phosphate fertilizer in Yinchuan greenhouse.Based on the widely cultivated pepper in Yinchuan as the research object,setting the different dosage of phosphate fertilizer experiment,through the analysis of phosphate fertilizer effect on pepper growth,yield and economic benefit to screen the optimum applying phosphorus content.The results showed that increasing phosphate fertilizer could significantly promote the pepper plant growth during the early fruiting period.Suitable low phosphorus inputs could cause pepper plants robust.75~(-2)25kg·hm~(-2) phosphorus pentoxide dosage could promote the crown significantly increased but more had the opposite effect.The relationship between phosphate dosage and hot pepper production performance was a typical parabolic type,when the dosage of phosphorus pentoxide was less than 225kg·hm~(-2),with the increase of the dosage of phosphate fertilizer,the hot pepper production increased,but further increase dosage of phosphate fertilizer,leading to decline in output.The highest yield applying phosphorus pentoxide content was211.64kg·hm~(-2),but the maximum economic benefit phosphorus pentoxide dosage of the region was 187.14kg·hm~(-2).
