摘要
为了解滦南县北圈村苹果施肥现状,走访了该村50个农户,对果园产量、施肥种类及管理措施等进行了实地调研。结果表明:全村农户在苹果生产过程中,化肥施用量的变化幅度很大,但是不同的化肥施用量对苹果产量影响并不显著;氮、磷和钾肥投入过量的农户比例分别为74%、100%和72%;农户的施肥种类仍然是以化肥为主、有机肥为辅,且化肥以三元素复合肥为主、有机肥以农家肥为主;此外,化肥施用时间与果树生理需求不匹配。为此,提出了采用"定果施肥"方式,加强科学施肥,提高有机肥和微量元素的投入,从而改善果实品质和提高经济效益。
In order to understand the status of fertilization for apple in Beiquan Village of Luannan County,50 farmers were interviewed to conduct on-the-spot research.The survey indicators includes the apple yield,types of fertilizers and management measures.The results showed that the chemical fertilizer application rate varied greatly among farmers,but it had no significant impact on the apple yield.The proportion of farmers with excess inputs of nitrogen,phosphorus and potassium fertilizers was 74%,100%and 72%,respectively.The chemical fertilizer was the dominant nutrient source which was mainly compound type and organic fertilizer was used as a supplementary most of which was from farmyard.In addition,the chemical fertilizer application time could not meet the requirements of fruit trees in different stages.Therefore,the mode of target fertilization according yield level was proposed,it was suggested that the application of organic fertilizer and microelement should be promoted to improve fruit quality and economic benefits.
