不同沼肥施用量对露地芹菜生长发育和品质的影响

Effects of different application rates of biogas fertilizer on growth,development and quality of open field celery

为探索沼肥基肥不同施用量对芹菜生长发育和品质的影响,试验以露地芹菜施用不同量沼肥基肥,以农家肥做对照,研究沼肥对芹菜生长、性状、产量和品质的影响。结果表明:以沼肥做基肥可有效提高芹菜的品质,在锡林郭勒盟地区以37500～45000 kg/hm^2沼渣肥做基肥,追施沼液可有效提高芹菜的品质及抗病性,减少生产成本和提高产品价值,生产中辅以少量化肥亦可减少产量损失。

This study explored the eftects of different application rates of anaerobic digestate fertilizer （ADF）on the growth and quality of celery. The experiment applied different concentrations of ADF to open field celery, used famlyard manure as a control, and measured the effect on growth, traits, yield and disease resistance. The results showed that using ADF can improve the quality and disease resistance in celery. In Xilin Gol League, biogas slurry is applied as a basing fertilizer at 37 500-45 000 kg/hm^2 and can effectively improve the quality and disease resistance of celery, reduce production costs and increase product value. In addition, using a small amount of chemical fertilizer can also reduce production losses.
