【摘要】 板栗矿质营养是板栗生长结实不可缺少的重要营养物质。当年板栗树体矿质营养的贮藏对于来年板栗的生长发育和产量有着密切的关系。有效的施肥量可以增加肥效的利用率,提高板栗的矿质营养的贮藏,从而提高板栗产量和防止大小年出现。通过运用凯氏定氮法测定其全氮的含量,等离子发射法测定其全磷、全钾的含量,对比研究不追肥、传统施肥、专用、配方和配方施肥+喷肥这5种不同方法的施肥效果。结果表明,配方施肥+喷肥方法能最有效地提高板栗枝条矿质营养贮存,增加板栗N、P、K的含量,进而提高板栗果实产量。更多还原

【Abstract】 This article discusses the important role of mineral nutrients in the growth and fruiting of Chinese chestnut.The storage of mineral nutrients in the first year is vital to the growth and output of Chinese chestnut in the second year,and efficient methods of fertilizing can improve the utilizing of fertilizer,and raise the output of Chiese chestnut.By measuring the percentage of nitrogen,phosphorous and potassium with Kjeldahl and ICP-AES,and by reviewing effects of unfertilizing,fertilizing by a tree farm mode,special fertilizer of Chiese chestnut,formula fertilizer and union of formula and spraying fertilization,the conclusion has been drawn that union of formula and spraying fertilization can raise the storage of mineral nutrients in Chinese chestnut most effectively,enhance the percentage of N,P,K and the output of Chinese chestnut.更多还原
