以吉林地区关苍术为试材,设5个施肥量处理水平,即5kg/667m2(N1)、10kg/667m2(N2)、15kg/667m2(N3)、20kg/667m2(N4)、25kg/667m2(N5),以不施肥为对照,研究施用不同量氮肥对关苍术生育性状和产量性状的影响,探讨有利于关苍术高产的最佳施肥量。结果表明:施肥与不施肥比较,关苍术产量、质量有很大提高,不同施肥量对产量的影响达到显著或极显著的差异水平;最佳的施氮量为15kg/667m2(N3)。
Taking the herb of Guanseng in Jilin Province as test material, five treatment levels of fertilizer were set as 5kg / 667m2 (N1), 10kg / 667m2 (N2), 15kg / 667m2 (N3), 20kg / 667m2 N5). With no fertilization as control, the effects of applying different amounts of nitrogenous fertilizer on the fertility traits and yield traits of Atractylodes L. were studied, and the best fertilization amount for high yielding herb was studied. The results showed that compared with no fertilization, the yield and quality of Guanzhu were greatly improved. The effects of different fertilizers on yield were significant or extremely significant. The best nitrogen application rate was 15kg / 667m2 (N3).
