摘要: 应用“3414”试验设计方案,进行不同肥力水平下土壤氮磷钾肥效田间试验。结果表明:土壤肥力高水平时,施用氮、磷、钾肥料与缺素区相比平均增产效果为N>K>P,施氮效果最好,增产率为21.2%;土壤肥力中、低水平时施用氮、磷、钾肥料与缺素区相比平均增产效果为K>N>P,施钾效果最好,增产率分别为25.1%、26.0%。 高肥力水平土壤上,仙草氮磷钾经济施肥量为N 195.2 kg/hm2、 P2O5 83.8 kg/hm2和 K2O 204.4 kg/hm2,三要素最佳比例为1:0.43:1.05;在中肥力土壤上,仙草氮磷钾经济施肥量为N 193.8 kg/hm2、 P2O5 89.2 kg/hm2和K2O 238.7 kg/hm2 ,三要素最佳比例为1:0.46:1.23,多施用钾肥;在低肥力土壤上,仙草氮磷钾经济施肥量为N 186.4 kg/hm2、 P2O5 90.5kg/hm2和 K2O 231.8 kg/hm2,三要素最佳比例为1:0.49:1.24,少施氮肥,多施钾肥。

Abstract: Application of "3414" test design scheme of the soil under different fertility levels of NPK fertilizer effect of field experiment. The results show that the high level of soil fertility, application of nitrogen, phosphorus and potassium fertilizer materials and deficiency area compared with the average increase yield was N > K > P, N the best effect, the increase rate of 21.1%; Soil fertility, low level of application of nitrogen, phosphorus and potassium fertilizer materials compared with deficiency area average yield effect of K > N > P, K application effect is best, increase rate of 25.1%, 26.0% respectively. Economic high fertility soils, this product NPK fertilizer use for for N, P2O5 5.67 13.08 kg / 667 m2 of 667 kg K2O / 667 m2 and 13.76 kg/m2, best ratio of the three elements was 1:0.43:1.05, this product NPK economic fertilizer rate for N, P2O5 12.76 kg / 667 m2 of 5.87 kg K2O / 667 m2 and 15.49 kg / 667 m2, the three elements of the best ratio was 1:0.46:1.21, more K fertilizer; In low fertility soils, this product NPK economic fertilizer rate for N, P2O5 12.58 kg / 667 m2 of 6.11 kg K2O / 667 m2 and 15.76 kg / 667 m2, the three elements of the best ratio was 1:0.49:1.26, less amount of nitrogen and potassium application.
