摘  要:
文章通过测定苗木施肥后体内生理、生化指标,统计分析施肥效果,建立抗寒施肥模型。研究结果表明,提高苗木抗寒性的最佳处理为处理10,即每株施肥氮80g、磷40g、钾60g抗寒性为最优。

摘  要:
In this paper the physiological and biochemical index of seedlings are determined, the fertilization effects are analyzed, and the model of cold-resistance fertilization is established. The results show that Test No. 10 is the best treatment to improve the cold resistance of seedlings, i.e.,80 g of nitrogen, 40 g of phosphorus, and 60 g of potassium.
