Study on Application Rates of Nitrogen,Phosphorus and Potassium Fertilizer in Aconitum georgei Comber.Cultivation Based on'3414'Experiment
摘要
Abstract
To explore the optimal fertilization ratio and amount of Aconitum georgei Comber.in Lijiang City,Yunnan Province,and to provide suitable fertilization scheme for fertilizer reduction and efficiency enhancement of the Aconitum georgei Comber,the effects of different nitrogen,phosphorus and potassium ratios on the yield,growth multiple and individual weight of the fresh roots tuber of Aconitum georgei Comber.were studied based on the'3414'fertilization design.Application amount of N,P and K was simulated using fertilizer effect function equation,and the interaction effects of N,P and K was analyzed.The results showed that the ratio of N,P and K had significant effects on root stock yield and weight of roots tuber,but had no significant effect on multiple of roots tuber.The effect of the three kinds of fertilizers on the yield was P fertilizer>N fertilizer>K fertilizer,and the effect of appropriate nitrogen and phosphorus was the best;The actual roots tuber yield,growth multiple and individual weight of the N2P2K3 were the highest,which was 6512.39 kg/hm2,1.51 times and 15.55 g every individual,respectively;effect of N,P and K on roots tuber yield of Aconitum georgei Comber.was interactive.The regression analysis results showed an atypical ternary quadratic fertilizer effect model existing between N,P and K fertilization rates and roots tuber yield,but binary quadratic function and unary quadratic function failed to give proper regression.Yield frequency analysis was used to determine the proper recommended fertilizer application amount.The optimal fertilization ratio was N2P2K3(nitrogen,phosphorus and potassium were 138.00,120.00 and 351.00 kg/hm2,respectively);a combination medium P and medium K was advantageous to N efficiency,a combination medium N and medium K was advantageous to P efficiency,a combination medium N and medium P was beneficial to K efficiency.The recommended amount of nitrogen fertilizer was 99.66-127.21 kg/hm2,phosphorus fertilizer was 80.94-110.42 kg/hm2 and potassium fertilizer was 157.82-215.32 kg/hm2,the corresponding ratio was 1:0.64-1.10:1.24-2.16 by the roots tuber yield frequency analysis.关键词
