生物有机肥对苹果产量品质及化肥减施效果的影响

Effect of Bio-organic fertilizer on Apple Yield,Quality and Reducing Fertilizer

2020年在辽宁苹果主产区开展生物有机肥替代化肥田间试验,设置5个处理进行对比分析。结果表明:667 m^(2)施用600 kg生物有机肥以替代40%的底肥,可使苹果增产2.4%~28.2%,平均增产率达9.0%以上;在保障产量情况下,施用1200 kg生物有机肥可完全替代底肥;生物有机肥替代部分化肥可提高苹果品质,VC含量可增至0.30~0.73 mg/100 g,可溶性固形物含量增至0.71%~0.93%,可溶性糖含量增幅在0.67%~1.01%。

In 2020,the field experiment of replacing biological organic fertilizer was carried out in the main apple producing area of Liaoning province,and 5 treatments were set up for comparative analysis.The results showed that:Applying 600 kg of bio-organic fertilizer to replace 40%of base fertilizer in 667 m^(2) increased by 2.4%to 28.2%,the average yield rate above 9.0%;In the case of guaranteed yield,the application of 1200 kg bio-organic fertilizer can completely replace the base fertilizer;Bio-organic fertilizer to replace some chemical fertilizer can improve the quality of apple,VC content can increase to 0.30~0.70 mg/100 g,soluble solid content increased to 0.71%~0.93%,soluble sugar content increased from 0.67%to 1.01%.
