北京怀柔地区钉型腐殖酸复混板栗专用肥的研究初报

Studies on NailForm Compound Fertilizer with the Prescriptions Special for Chinese Chestnut in Huairou Country,Beijing

通过在北京市怀柔县沙峪乡红军庄低产坡地做板栗专用肥试验，将新型板栗复混专用肥（“钉型”肥）分９种配方肥料与等量养分的粉态肥及当地传统施肥为对照，在产量、百果重、叶绿素含量、百叶鲜重、干重和空蓬率等几个指标上进行了比较．结果表明，“钉型”肥中以５，６，７配方与粉态肥相同配方及当地传统施肥相比，在以上几个指标上均达到显著或极显著的差异水平．本试验结果为进一步优选出适合北京地区板栗生长的专用肥奠定了基础．

For testing the nailform fertilizers with 9 prescriptions desigened for Chinese chestnut(Castanoa mollissimaBL), the experiments were carried out with the powder fertilzier and traditional fertilzier as controls in low yield area of Chinese chestaut plantation in Shayu Township, Huairou Country,Beijing. The nailform fertilizers with prescriptions 5,6 and 7 were significantly or extremesignificantly better than the powder fertilizers with corresponding prescriptions and better than the traditional fertilizer in respect of yield,100 kernel weight,chlorophyll content, fresh weight and dry weight of 100 leaves, and the rate of empty bitter fleabane.
