| 摘 要： | 本研究以茶叶为材料,采用二次饱和D-最优设计(311-B方案)设计,研究了N、P、K施用量与茶叶产量的相关性,并建立了相应的数学模型。结果表明:N、P、K三元素中,N肥的施用与茶叶产量的形成呈显著正相关,P、K也有一定的影响,它们作用的大小顺序为N>P>K,N-P、N-K、P-K之间的互作达到显著水平。经多元回归和频率分析方法理论上得到茶叶N、P、K三元素最佳方案是:N:0.406~0.435g/kg土,P2O5:0.159~0.170g/kg土,K2O:0.186~0.198g/kg土,N:P2O5:K2O为1:0.39:0.46。 |

| Abstract: | The return two times set up juices optimumly trying to adopt“311-B”,a three-factor (N,P,K)substrate cultivation experiment was conducted by using tea.The regression equations of the relationship between N,P,K and the effects on the yield were established.The results indicated that the yield of tea would increase with high nitrogen supply,and P,K had certain effects on it,the order is N>P>K,the interactions of N-P,N-K and P-K to the yield were significant.Considering both the yield and quality of the hot pepper,the combinations of N,R K were optimized as follows:N:0.406~0.435 g/kg soil,P2O5:0.159~0.170 g/kg soil,K2O:0.186~0.198 g/kg soil,and N:P2O5:K2O was 1:0.39:0.46. |
