Abstract:
Taking 2-year-old Panax notoginseng as test material，the effect of fertilizing different proportion of N，P and K on the growth，yield were studied and to reveal optimal fertilization mode under the target yield of Panax notoginseng by the optimal design of N，P and K with four levels in the field experiments.The results showed that treatment (N∶P∶K=0.192 5∶0.192 5∶-1) had the highest height which was higher than the control treatment 16.9%，however，another treatment (N∶P∶K=-0.291 2∶1∶1) had the shortest height which was less than the control 20.4%.Underground fresh weight of different treatments were higher than the control，especially，weight of fresh and dry of the treatment (N∶P∶K=1∶1∶-0.291 2) were the largest among them.The treatment (N∶P∶K=-1∶-1∶1) was more conducive to the accumulation of the effective ingredients for the biggest percentage of the total saponin contents，while the treatment (N∶P∶K=-0.192 5∶0.192 5∶-1) had the biggest plant production.Different ratio of N，P and K had significant on plant growth.Nitrogen and phosphorus could promote plant height growth，improve crop yields and potash can promote roots.Potash was more conducive to the accumulation of the active ingredient because of the biggest percentage of the total saponin content，while was not conducive to the accumulation of the plant products.The fertilizer amount of N，P and K was N 71.60-149.37 kg/hm2，P2O5 46.54-110.62 kg/hm2，K2O 236.35-444.72 kg/hm2 when Panax notoginseng target yield at 861.541-1 139.458 kg/hm2.
