生物有机肥替代部分化肥对甜樱桃果实的影响

Effects of bio-organic fertilizer instead of partial chemical fertilizeron sweet cherry fruit

以常规施肥做对照,试验生物有机肥替代部分化肥对甜樱桃生长发育、产量、品质及效益的影响。结果表明,在甜樱桃关键生育时期,由生物有机肥替代20%化肥养分量处理的叶片增厚、叶绿素含量SPAD值增加;果实硬度增加,可溶性固形物和Vc含量增加,酸度降低,单果重比对照增加0.2g,每666.7m^2增产153.9kg,增产率11.75%,效果显著,综合收益增加3437元;由生物有机肥替代40%化肥养分处理的品质有所改善,但减产39.5kg,减产率3.02%,收益下降。

The effects of partial replacement of biological organic fertilizer with chemical fertilizer on the growth,yield,quality and benefit of sweet cherry were studied using conventional fertilization as control.The results showed that during the key growth period of sweet cherry,the leaf thiCKness,SPAD value,fruit hardness,soluble solids and Vc content increased,but the acidity decreased,the single fruit weight increased by 0.2g,and the yield increased by 153.9kg per 666.7m 2,and the yield increase rate was 11.75%,the comprehensive income increased by 3437 yuan.Compared with conventional fertilization,bio-organic fertilizer instead of 20%chemical fertilizer.The quality of bio-organic fertilizer instead of 40%of chemical fertilizer was improved,but the yield and income decreased.The yield decreased by 39.5kg,and the yield decreased by 3.02%.
