粒状钙镁磷肥对长白山欧李产量和品质的影响

Effects of GFMP on Yield and Quality of Hybrid Seedlings of Prunus humilis

以4a生长白山欧李为试材,研究了粒状钙镁磷肥(GFMP)施用时期和施用量对长白山欧李产量和品质的影响。结果表明:施肥时期、施肥量与欧李果实的含糖量、含酸量、糖酸比、单果重、单株产量有着密切关系,GFMP以花后6周施用250g/株对长白山欧李产量和品质提高效果最为明显。果实成熟前30d施用300g/株对长白山欧李产量与品质的提高也具有一定的作用,但果实的综合指标及肥效利用率不如花后6周施用250g/株效果好。

Taking 4-year-old Prunu.; humilis in Changbai mountain as material, the effect of GFMP application period and fertilization amount on the yield and quality of Prunus hurnilis were studied. The results showed that application period and fertilization amount had close relationship with the sugar content, acid content, sugar-acid ratio, fruit weight, yield per plant of Prunus humilis fruits;the effects in improving the yield and quality of Prunus hurnilis when spring 250 g/plant GFMP in the sixth week after becoming flowers was the most obvious. Spring 300 g/plant GFMP in the thirtieth day before fruits ripening had some functions in improving the yield and quality of Prunus hurnilis, but the integrated indicators and fertilizer efficiency utilization of the fruits were worse than spring 250 g/plant GFMP in the sixth week after becoming flowers.
