北票半干旱地区大扁杏整地施肥造林效果分析

Afforestation Effect of Site Preparation,Fertilization of Armeniaca vulgaris in Semi-arid Area of Beipiao City

基于生产试验,研究了不同整地方式和根部施肥不同施肥方法对大扁杏新梢生长量和杏核产量的影响,结果表明:梯田等高线整地方式优于鱼鳞坑和不整地的坡地对照,梯田整地比对照提高新梢生长量77.26%,新梢直径生长量提高69.70%;树冠投影环状施肥比对照提高杏核产量47.8%。整地方式和施肥方法显著影响大扁杏新梢生长量和杏核的产量。

Based on the production experiment,the effect of different methods of soil preparation and root fertilization with different fertilization methods on growth of new-shoot and kernel yield of Armeniaca vulgaris was studied. Result shows that the method of site preparation of terrace contour line is optimal than that of scale-pit site preparation and without site preparation; the terraced soil preparation improve the shoot growth by 77. 26% and the new shoot diameter increase by 69. 70%.The canopy-projection ring-fertilization increase the kernel yield of apricot by 47. 8% compared to the control. Soil preparation methods and fertilization methods affect the shoot growth kernel yield of Armeniaca vulgaris significantly.
