Abstract
The effects of fertilization modes on soil properties,agronomic characteristics,yield,and fertilizer use efficiency of strawberry under continuous mono-cropping condition were studied in a field plot experiment.Compared with the conventional fertilization mode,the optimized fertilization modes I and Ⅱ increased the activity of urease,available nitrogen and potassium contents in soil significantly,and enhanced the dry weight of underground part,length of flower stalk,number of floral bud per plant,and number of flower shoot per plant.The optimized fertilization mode I reduced the soil bulk density and increased dissoluble sugar content in fruit.By using the optimized fertilization modes I and Ⅱ,the yields of strawberry were increased by 58% and 39%,respectively,agronomic efficiencies of nitrogen,phosphate and potassium fertilizer were increased by 14.0-14.6 times and 8.6-9.5 times,PFPs(partial factor productivities) of nitrogen,phosphate and potassium fertilizer were increased by 47.5%-50.6% and 17.3%-28.7%,whereas relative yield were decreased by 36.4% and 28.0%,respectivly.It was demonstrated that optimized fertilization modes could improve the yield and fertilizer use efficiency of strawberry efficiently under continuous mono-cropping,with mode I better than mode Ⅱ.
