【摘要】 为了解决黄果梨栽培中盲目施用化肥，肥料利用率低的问题，本文在秋施基肥的前提下，以常规施肥量为基础，通过减少化肥施用量、添加肥料增效剂和土壤调理剂，对黄果梨进行化肥减施增效试验。结果表明：在果树生长阶段，追施化肥可有效提高果树的座果率、百叶重、枝条生长量、叶片营养水平、单株产量和果实品质；在添加肥料增效剂、土壤调理剂的基础上，减少常规化肥施用量20%，不会对树体生长、座果率、产量和品质产生明显影响。更多还原

【Abstract】 Based on the conventional application of chemical fertilizer,the experiment of chemical fertilizer reduction on Huangguo pear is carried out by reducing chemical fertilizer,adding fertilizer synergist and soil conditioner on the premise of applying basal fertilizer in autumn to solve the problem of low fertilizer efficiency caused by the blind application of chemical fertilizer in the cultivation of Huangguo pear. The results show that topdressing with chemical fertilizer in the growth stage of trees can effectively increase the fruit setting rate,louver weight,branch growth,leaf nutrient level,yield per plant and fruit quality;reducing the application amount of conventional chemical fertilizer by 20% will not have a significant impact on tree growth,fruit setting,yield and quality on the basis of adding fertilizer synergist and soil conditioner.更多还原
