摘要
在宽叶羌活大田种植条件下,研究了不同栽培方式、不同栽培密度对宽叶羌活药材产量的影响。结果表明:一年生移栽栽培方式宽叶羌活产量最高,三年后根部产量可达49.7kg/100m^2,高于种子撒播方式22.5%,高于种子条播方式14.9%。同时,密度试验表明20cm×20cm栽培密度产量最高,三年后根部产量可达54.8kg/100m^2。因此,宽叶羌活大田条件下的最佳栽培条件为育苗一年后移栽,20cm×20cm密度栽培。
The effect of different cultivation methods and planting density on yield of notopterygium forbesii. medicinal herbs were studied. The results show that the transplanting cultivation methods of N. forbesii annual yield was the highest,three years after the root yield of up to 49. 7kg/100m^2,more than 22. 5% seeds,14. 9% higher than that of seed drilling. At the same time,the density test showed that the density of 20 cm ×20cm was the highest,and the root yield was 54. 8kg/100m^2.
