摘要
为了促进甘肃省干旱区轻度盐碱地文冠果科学施肥种植,研究了不同种类的施肥处理对文冠果生长及土壤的影响。结果表明:施肥对文冠果生长和土壤都有正向促进作用。其中,复合肥对文冠果生长量促进作用明显,凹凸棒有机肥对土壤的改良作用更为明显。从长远来看,生产上以施有机肥为主,在花期增施钾肥促进坐果率,在果实膨大期增施磷肥促进果实生长,其余时间配施复合肥效果更好。
In order to promote scientific fertilization and cultivation of Xanthoceras sorbifolium in Gansu Province,the study researched the effects of different fertilization treatments on the soil and growth of Xanthoceras sorbifolium.The results showed that all fertilization had positive effects on the growth of Xanthoceras sorbifolium and soil quality.Among them,compound fertilizer significantly promoted the growth of Xanthoceras sorbifolium,and the effect of attapulgite organic fertilizer on soil improvement was more obvious.In the long run,organic fertilizer should be given priority in production.Potassium fertilizers should be added during flowering which can improve setting percentage,and phosphate fertilizers should be added during fruit expansion which can promote fruit growth.the rest of times compound fertilizers work better.
