| Abstract: | Based on investigation and analysis on the fertilization management and soil nutrients in the young(1～4 years old)and full fruit period(5～8 years old) of Lycium barbarrum in Caowotan town of Jingtai county,and soil nutrient testing of 20～40 cm,the study was conducted on the main problems and characteristic of soil nutrients in the different ages of Lycium barbarrum in this region.The results showed: the farmers paid attention to organic fertilizer,but the amount of application was less;and there was common phenomenon of emphasizing the application of N and P,but K of the chemical fertilizer application was neglected.The content of organic and total N was medium level or slightly lower,total P was very deficiency,total K was comparatively abundant,and the total K of young period orchard was more than full fruit period orchard.The content of available N and available P of young period orchard was lower,but the content of available N and available P of full fruit period orchard was medium level The pH of full fruit period orchard was lower than that of young period orchard. |
| Keywords: | Lycium barbarrum young period orchard full fruit period orchard soil nutrients yellow river irrigation area the central section of Gansu |
