测土配方施肥对金银花产量和质量的影响
Influence on Yield and Quality of Lonicera japonica by Soil Testing and Formulated Fertilization
摘要
Abstract
In order to study the effects of nitrogen,phosphorus and potassium fertilizer on the yield and quality of Lonicera japonica test of soil testing and formulated fertilization was carried out in Linyi,Shandong in the paper.Overall,three fertilizer factors (N,P2O5 and K2 O) are designed,together with four fertilization levels (Level 0:no fertilizer application;Level 1:0.5 time as much as the common fertilizing amount;Level 2:common rate of fertilizer application;Level 3:1.5 times of the common rate of fertilizer application),totally 14 types of proportional fertilization treatments are involved.As is suggested in the findings,the fertilization treatment has a significant influence on the output of Lonicera japonica.Among them,the highest yield of N2P3K2 reaches 391.8 g,37.6％ surpassing the control.For every gram of nitrogen,phosphorus and potassium fertilizer applied in the field,the output of bud was increased by 1.98 g,8.21 g and 4.56 g,respectively.The phosphorus content of soil is the primary factor restricting the honeysuckle yield.In addition,the paper formulates the fitting equation of the yield per plant of honeysuckle and fertilization effect of nitrogen,phosphorus and potassium fertilizer.The recommended amount of fertilizer is 34.9 ～ 47.9 g,13.1 ～ 14.4 gand 18.5 ～ 23.8 g respectively for N,P2O5,and K2O,with the yield per plant being 387.0 ～ 430.3 g.The nitrogen,phosphorus and potassium fertilizer are all positively correlated with the length of flower bud,among which the phosphorus fertilizer displays marked influence.Apart from that,the phosphate fertilizer also constitutes key fertility factor affecting the thousand-flower bud weight,as well as key element in the growth and development of bud.In terms of different fertilization treatments,a significant positive-corre ation was observed between the contents of phosphate fertilizer and chlorogenic acid.At the same time,the synergistic effect of phosphate fertilizer and potash fertilizer is positively correlated with the content of luteolin.The study provides a theoretical reference for the rational formula fertilization of nitrogen,phosphorus and potassium in Lonicera japonica.关键词
