有机无机肥配施对葡萄品质及土壤养分的影响

Effects of Organic Combined with Chemical Fertilizers on Grape Quality and Soil Fertility

为实现土壤质量与葡萄品质的协同提升,以6年生‘阳光玫瑰’为试材,通过田间试验调查不同施肥处理对葡萄产量和品质及土壤养分的影响。结果表明,与常规施肥相比,有机无机肥配施能够显著提高葡萄的可溶性固形物与Vc含量,降低果实硬度、密度、出汁率以及可滴定酸含量,并增加葡萄产量。其中化肥减施30%+30 t·hm^(-2)有机肥处理与常规施肥相比,果实的可溶性固形物、Vc含量和产量分别增加10.16%、21.18%和15.15%,可滴定酸含量降低18.92%。同时,有机无机肥配施提高了葡萄园土壤养分含量,使土壤有机质含量明显提升。基于以上结果,科学地有机无机肥配施实现了葡萄园土壤质量与葡萄产量和品质的协同提升。

In order to realize the synergistic improvement of soil fertility and grape quality,six-year-old'Shine Muscat'as the test material in this experiment,to investigate the effects of different fertilization treatments on grape yield and quality and soil nutrients by field experiment.The results showed that compared with conventional fertilization,optimal fertilization reduction combined with organic fertilizer could significantly increase grape soluble solid and Vc content,reduce fruit hardness,density,juice yield,and titrable acid content,and increase grape yield.Among them,under inorganic fertilizer reduction of 30%+30 t·hm^(-2) organic fertilizer treatment compared to conventional fertilization,the soluble solid content,Vc content and yield of grape increased by 10.16%,21.18%and 15.15%,respectively,and the titrable acid content decreased by 18.92%.At the same time,the combined application of organic and inorganic fertilizers promoted the soil nutrient content,especially the content of soil organic matter was significantly increased.Based on the above results,the combined application of organic and inorganic fertilizers realized the synergistic improvement of vineyard soil fertility and grape yield and quality.
