茶园沼液水肥一体化技术应用研究

Application Research of Fertigation Technology with Biogas Slurry in Tea Garden

通过田间试验,探讨沼液水肥一体化技术模式对茶叶产量及经济效益的影响。结果表明,在满足土壤肥力标准下,氮肥是影响茶树生长最主要因素,“沼液+化肥”能满足茶树生长所需养分;茶园水肥一体化喷施沼液较常规化肥节肥16.23%,增产6.67%,增值5.17%,施肥效率提高10倍以上,具有较高的推广应用价值。

Through field test,the influence of fertigation technology with biogas slurry on tea yield and economic benefit was studied.The results showed that nitrogen was a major element affecting the growth of tea tree when the fertilizer in soil was above the standard,and thus the“biogas slurry+chemical fertilizer”was sufficient to provide the nutrients for tea growth.Comparing to the way of conventional fertilization,the net weight of fertilizer of fertigation technology with biogas slurry was decreased 16.23%,the yield was increased 6.67%,the income was increased 5.17%,the fertilization efficiency was increased by more than 10 times.The fertigation technology with biogas had the value of popularization and application.
