痕量灌溉条件下不同施肥量对甜椒产量和品质的影响

为探索痕量灌溉条件下甜椒适宜的施肥量,以甜椒‘京甜3号’为试验材料,研究春季日光温室栽培条件下,痕量灌溉条件下不同施肥量对甜椒生长、产量和品质的影响。试验结果表明,常规施肥量下降25%处理产量最高,与常规施肥量和施肥量0处理相比,产量分别增加8%和27%;与常规施肥量相比,Vc含量提高8%,硝酸盐含量降低43%,品质有所提高。综合产量和品质指标,在该试验条件下,认为常规施肥量下降25%,即每次施肥112.5kg/hm2能够获得甜椒高产优质。

Effects of different fertilizing amount on yield and fruit quality of Pimento under trace irrigation

In order to explore the appropriate fertilizing amount under trace irrigation,the effects of fertilizing amount on pimento growth,yield and fruit quality of spring pimento’jingtian No.3’in solar greenhouse was studied.The results showed the treatment of 25% conventional fertilization received the highest pimento yield.The yield increased by 8% and 27% compared with conventional fertilization and control respectively.The content of VC increased by 8% and the nitrate content decreased by 43% compared with conventional fertilization.With analyzing the properties of pimento yield and quality in this experiment,decreasing fertilizing amount by 25% than conventional fertilization can result in high pimento yield and quality.
