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:0.406~0.435βg/kg土,P2O5:0.159~0.170βg/kg土,K2O:0.186~0.198βg/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: 0.406~0.435βg/kg soil, P2O5: 0.159~0.170βg/kg soil, K2O: 0.186~0.198βg/kg soil, and N:P2O5:K2O was 1:0.39:0.46.
