虾肽有机肥与磷肥配施对苹果产量和品质的影响

Effect of Combined Application of Shrimp-peptide Organic Fertilizer and Phosphatic Fertilizer on Yield and Quality of Apple

[目的]研究虾肽有机肥(SPOF)与磷肥配施的协同增效作用。[方法]采用田间小区试验,设尿素1.4 kg/株(CK)、尿素1.4 kg/株+农家肥50 kg/株+磷酸二氢钾1.54 kg/株(TT1)、尿素1.4 kg/株+SPOF 30 kg/株+磷酸二氢钾1.54 kg/株(TT2)、尿素1.4 kg/株+SPOF 30 kg/株+普通过磷酸钙0.83 kg/株+磷酸二氢钾1.25 kg/株(TT3)。[结果]各处理的产量TT3>TT2>TT1>CK,且TT3达到了显著水平;TT3的品质指标,即可溶性固形物、维生素C、蔗糖、葡萄糖以及硬度均达到了显著水平。[结论]TT3处理虾肽有机肥和磷肥(SSP+KH2PO4)协同将其效力发挥到最大。

[Objective] To study the synergistic effect of shrimp-peptide organic fertilizer(SPOF)and phosphatic fertilizer. [Method] A field plot test was adopted including four experiments(Urea 1.4 kg/plant,CK;Urea 1.4 kg/plant + farmyard manure 50 kg/plant + KH2 PO41.54 kg/plant,TT1;Urea 1.4 kg/plant +SPOF30 kg/plant + KH2 PO41.54 kg/plant,TT2;Urea 1.4 kg/plant +SPOF 30 kg/plant + SSP 0.83 kg/plant + KH2 PO41.25 kg/plant,TT3). [Result] The yield of each treatment was TT3>TT2>TT1>CK,and TT3 reached significant level. The character indexes of TT3,such as soluble solids,Vc,sucrose,glucose and fruit hardness,reached significant levels. [Conclusion] TT3 could maximize the effectiveness cooperating with SPOF and phosphatic fertilizer(SSP+KH2 PO4).
