Abstract
Based on orthogonal experiment, the paper studies on different proportion of nitrogen, phosphorus and potash fertilizer and only nitrogenous fertilizer on seedling growth of the Pistacia chinensis Bunge. Through analysis of the height, dry weight and shoot to root ratio of the seedling, the experiment has proved that the suitable amount of fertilization for only nitrogenous fertilizer is 0.5~1g/kg per seedling. For different levels of nitrogen, phosphorus and potash fertilizer, the applicable proportion of N∶P_(2)O_(5)∶K_(2)O is equal to 12~6∶1∶2.
