生物有机肥对“黄金”梨栽培的影响

Effect of Biological Organic Fertilizer on ‘Huangjin' Pear Cultivation

以新乡市稼豪生物制剂有限公司生产的"稼豪"牌生物有机肥、青岛"龙力"牌生物有机肥、三门峡龙飞生物工程有限公司生产的"龙飞大三元"牌有机肥为试材,以青岛昌华集团公司生产的硫酸钾复合肥作对照,于2010—2012年研究了生物有机肥对10年生"黄金"梨栽培土壤有机质及土壤营养成分的影响,对树体叶片生长,果实主要性状和产量的影响。结果表明:"黄金"梨施用生物有机肥后土壤有机质含量显著增加,且沙壤土比沙土有机质含量增加幅度大;土壤中水解氮明显提高,有效磷和有效钾绝对值显著增加。在沙壤土施用生物有机肥效果较好。"黄金"梨百叶重施用生物有机肥效果不明显,"稼豪"牌和"龙力"牌生物有机肥处理的百叶厚在盛花期和成熟期比对照硫酸钾复合肥增加极显著,而"龙飞大三元"牌有机肥增加不显著。"稼豪"牌生物有机肥和"龙力"牌生物有机肥可以在生产上推广应用。

Using three bio-organic fertilizer as test materials（Xinxiang City Jia Hao Biological Preparation Co.Ltd.‘Caterpillar hao＇brand of bio-organic fertilizer,Qingdao ‘Long Li＇brand of bio-organic fertilizer,Sanmenxia Longfei Biological Engineering Co.Ltd.production of‘The dragonfly triple double＇brand of organic fertilizer and potassium sulfate）,Qingdao Changhua group company production of compound fertilizer as the control,in 2010—2012,the effect of bio-organic fertilizer on the 10-year-old of‘Huangjin＇pear cultivation of soil organic matter and soil nutrients,on the growth of tree leaves,main characters and yield of fruit were studied.The results showed that‘Huangjin＇pear soil organic matter content increased significantly,after applying bio-organic fertilizer and the content of organic matter of the sandy loam increased greatly than that of sandy soil;hydrolysis of nitrogen in the soil increased,the absolute value of available phosphorus and available potassium increased significantly.The effect of applying bio-organic fertilizer in sandy loam soil was good.‘Huangjin＇pear shutter was replicating organic biological fertilizer effect was not obvious,thick shutter‘Caterpillar hao＇brand of bio-organic fertilizer and ‘Long Li＇brand biological organic fertilizer treatment full-bloom stage and mature stage than control potassium sulfate compound fertilizer increased significantly,and ‘The dragonfly triple double＇brand of organic fertilizer increased that not be significantly.‘Caterpillar hao＇brand of bio-organic fertilizer and bio-organic fertilizer‘Long Li＇brand could be applied in production.
