| Abstract
|
| [Objective] To explore the effects of N,P and K ratio on the yield,quality,nutrient absorption and soil of salvia miltiorrhiza,and provide technical support for standardized fertilization of salvia miltiorrhiza.[Methods] Pot experiment was carried out with "3414" design to study the effects of different N,P and K fertilization treatments on the growth,nutrient absorption and content of medicinal ingredients of salvia miltiorrhiza and soil physiochemical properties.[Results] N2P1K2 had the best growth,and the root diameter,root length,aboveground dry weight and underground dry weight increased by 74.15%,31.41%,278.54% and 329.40%,compared with the CK.Soil pH increased with the increased N,P and K fertilizers.In N2P1K2,the contents of soil available N,P and K increased by 37.01%,17.26% and 10.72%,compared with the CK.The contents of total nitrogen,phosphorus and potassium were increased by 67.88%,18.62% and 93.34% under N2P1K2 treatment compared with the CK.In N2P1K2,the contents of tanshinone and salvianolic acid B were 3.33,51.45 mg/g,increased by 26.05%,49.52% compared with the CK.[Conclusion] N,P and K ratio can affect the growth index and soil nutrient status of salvia miltiorrhiza,especially can effectively improve the yield and active component content of medicinal materials.The best and recommended fertilization scheme of N,P and K is 0.389 1,0.205 3 and 0.521 4 g/L,which has a certain popularization significance in the large-scale field planting activities of salvia miltiorrhiza. |
