Abstract:: 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.75-225 kg?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 225 kg?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 was 211.64 kg?hm-2,but the maximum economic benefit phosphorus pentoxide dosage of the region was 187.14 kg?hm-2.
