| 摘 要： | 应用311-A最优回归设计方法,研究了冬季施用氮、磷、钾对于工厂化育苗条件下茶苗生长的影响,建立了施肥与茶苗生长过程中株高变化的多项式回归模型,并且寻求出其最佳用量方案。当N=185.7 kg/hm2,P2O5=239.8 kg/hm2,K2O=0.0 kg/hm2,株高的最大增加量预计为8.3 cm。

| Abstract: | 311-A optimum regression design was used to study effects of application of nitrogen,phosphorus and potassium on tea breeding in greenhouse in winter.The regression models was established to obtain the optimum application of NPK fertilizers.When the amount of fertilizers was N= 185.65 kg/hm2,P2O5=239.75 kg/hm2,K2O=0.00 kg/hm2,the maximum length of tea seedlings was predicted to increase 8.3 cm. |
