| 摘 要： | 以四川纳溪区巨桉试验林为研究对象,运用植物营养矢量诊断法,分析植物养分受限制状况、交互作用、施肥效应,结果表明:四川纳溪巨桉试验区以K为第1养分限制因子,P为第2限制因子,N不受限,B素缺乏,P对Ca、Mg存在拮抗作用,对B有促进作用.施肥效应可延续3年以上.

| Abstract: | The principle, technique and its application of vector diagnosis were introduced systematically in the paper. The nutrient-limited status, interactions among nutrients and fertilization effect in Eucalyptus grandis plantation in Naxi County, Sichuan, were analyzed here based on the principle and technique of vector diagnosis. The results showed that potassium was the first nutrient_limited factor, phosphorus second one, nitrogen was not limited, and boron was deficient. Moreover, phosphorus fertilizer antagonized the effects of calcium and magnesium fertilizers, but promoted the boron fertilizer effect. On the whole, the fertilization effect would continue for more than three years. |
