有机无机肥料配施对益都椒产量及红色素含量的影响

Effect of Combined Application of Organic and Inorganic Fetilizer on Yield and Red Pigment of Yidu Pepper

采用"3414"方案,研究了N、P、K及有机肥配施对益都椒产量及红色素含量的影响.结果表明:有机无机肥料配施使益都椒的平均产量达到3948kg/hm2,比单施无机肥产量增长16.8%,红色素含量达到了168kg/hm2,增长31.25%.有机肥在0kg/hm2-1300kg/hm2内对产量和红色素的含量均产生极其显著的影响.N肥是益都椒产量的主要限制因子,但对红色素含量没有明显影响.在本试验条件下,比较好的施肥方案是尿素400.2kg/hm2,过磷酸钙400.2kg/hm2,硫酸钾300.kg/hm2,有机肥1100.4kg.在此条件下益都椒产量为5263kg/hm2,红色素的产量达到243kg/hm2.

＂3414＂ program was used to research the N、P、K and mixture of organi-inorganic fertilizer how to affect the productivity of YiDu pepper and content of red pigment.The results indicated that： the average productivity of Yidu pepper reach 3948kg/ hm2 with the Function of organic and inorganic fertilizers,productivity increased 16.8% compared with just using inorganic fertilizer,red pigment contents reached 168kg/ hm2,up 31.25%.Organic fertilizer have extremely significant effects on the productivity and red pigment content within the range of 0kg/hm2-1300kg/hm2.N fertilizer is the main limiting factor of Yidu pepper Productivity,but have no obvious effects on red pigment content.In this experimental condition,the fertilizing program of urea 400.2kg/ hm2,superCalcium phosphate 400.2kg/hm2,potassium 300.kg/hm2 organic fertilizer 1100.4kg is the better.Under the condition,Yidu pepper productivity is 5263kg/hm2,red pigment productity reached 243kg/ hm2.
