Effect of Slow Release Fertilizer and Application Method on the Absorption and Utilization of Phyllostachys praecox 'Prevernalis'
In Phyllostachys praecox 'Prevernalis' stand in Hangzhou,Zhejiang province,9 standard plots were established.In November 2017 and November 2019,soil of 0-40cm were sampled for determination of physiochemical properties.In 2018,experiments were conducted on hole(HSF)and furrow(FSF)application of slow release fertilizer in stand with compound fertilizer as control(CK).In January 2019,3 new bamboos of each plots were selected for detection of biomass.The results showed that under different treatments,soil pH decreased in each plot,especially in the control,about 0.52.The accumulation of soil available N,P,and K were as follows:CK>HSF≈FSF,and the accumulation of soil available N,P,and K in CK increased by 26.40％,20.74％,and 3.98％.Dry biomass of bamboo had an opposite trend,CK(985.37 g)<HSF(1276.49 g)≈FSF(1 119.85 g).The contents of N,P,and K,and the dry biomass of plants had the same trend as the dry biomass of plants,CF<HSF≈FSF.Compared with CK,HSF and FSF promoted the absorption of N,P,and K.The experiment demonstrated that HSF and FSF were significantly better than CK on the absorption and utilization of fertilizer,especially HSF had the most significant effect on the absorption and utilization of above ground part,and FSF had the most significant effect of underground part of Ph.praecox 'Prevernalis'.
