摘要
以"大石早生李"为试材,研究了连续2年农家肥、菌渣、缓释肥处理对土壤养分、果实品质和产量的影响。结果表明:农家肥更好地提高了土壤有机质、全氮、全磷、速效钾含量,分别比对照提高了60.61%、79.08%、26.00%、41.44%。菌渣提高土壤速效磷含量效果最显著,比对照提高了43.51%。缓释肥将全钾含量提高了10.05%,效果比其它处理显著。农家肥改善果实品质效果最为显著,果实硬度、可溶性固形物含量、可溶性糖含量、维生素C含量分别比对照提高了25.98%、16.15%、49.39%、27.42%,可溶性酸含量降低了19.39%,果实钙、镁、锌、铁含量高于其它处理。缓释肥改善果实矿质元素含量的效果不显著。3个处理均提高了果实单果重,其中菌渣效果最好,增重率为27.45%。缓释肥能显著提高李子产量,单株平均产量达到74.86kg,比对照提高了54.83%。
Taking Prunus salicina＇Oishiwase＇ as test material, the effects of armyard manure, edible fungi residue, and slow release fertilizer on the soil nutrient and fruit quality were studied. The results showed that the farm manure significantly increased the soil organic matter, total nitrogen, total phosphorus, available potassium, it better than other treatments, were increased by 60. 61%, 79. 08 %, 26. 00 %, 41.44 %. Edible fungi residue had the most significant effect to improve the soil available phosphorus,it was increased by 43. 51% than CK. Slow release fertilizer had more obvious effect on total potassium than the other treatments, it was increased by 10. 05 %. Farmyard manure increased fruit firmness,the total soluble solids content, fruit soluble sugar content,vitamin C content by 25. 98%, 16. 15% ,49. 39%, 27. 42 %, soluble acid content decreased by 19. 39 %, it had the most significant effect. Farmyard manure could improve the fruit calcium,magnesium,zinc,iron, it was better effect than other treatments, and the effect of slow release fertilizer on improving the fruit mineral element was not significant. 3 treatments had a significant effect on increased fruit weight, edible fungi residue was the best, and the weight was increased 27. 45%. Slow release fertilizer can obviously improve the plum yield,the plum yield per plant was 74. 86 kg,it was increased 54. 83% higher than the control.
