配比施肥对槟榔幼苗肥料利用率及养分协同效应的影响
Effects of Fertilization Ratio on Fertilizer Uptake and Nutrient Syn-ergy of Areca catechu Seedlings
摘要
Abstract
In order to explore the effects of N,P and K fertilizers on the growth and nutrient uptake of areca nut seedlings and provide a scientific fertilizer application in field management,areca nut seedlings were used to conduct the"3414"fertilizer ratio in pots at the greenhouse.Fertilization significantly increased biomass and fertilizer utilization of areca nut seedlings.In balanced nitrogen,phosphorus and potassium fertilization,N and P fertilizers had the maximum utilization.Balanced nitrogen and potassium fertilization without phosphate fertilizer,K fertilizers had the maximum utilization.The N content was the main factor affecting the stem and leaf biomass,while the P content was the main factor affecting root biomass.Correlation and path analysis indicated that N and P could synergistically improve the growth of areca nut seed-lings,but they were affected by the application of K fertilizer.However,N,P and K fertilizers could reach balance and synergy to improve the growth of seedlings.In conclusion,N,P and K fertilizers in a rational proportion was beneficial for the nutrient uptake and utilization of areca nut seedlings,and N∶P∶K=2∶2∶2(T6)was the most suitable fertilization ratio.关键词
