摘要
为满足花生生产绿色可持续发展的需求,以花生品种豫花22号为试验材料进行田间试验,设置常规施肥(农民习惯施肥)、施肥量减少30%、施肥量减少25%共3种施肥量,起垄和平作2种种植模式,共6个处理,研究减量施肥及起垄对花生产量的影响。结果表明,常规施肥下,与平作种植模式相比,起垄种植花生荚果增产不显著;在肥料减施25%、30%的情况下,起垄种植的花生荚果产量显著增加;平作条件下,肥料减施25%的花生荚果产量显著降低;但在起垄条件下,肥料减施25%对花生荚果产量的影响不显著,说明合理减量施肥和起垄种植不仅不影响花生产量,还能减少肥料投入,降低生产成本,降低养分流失造成面源污染的风险。
In order to realize the sustainable development of green ecological production of peanut,three fertilization amount,such as conventional fertilization(farmers’habitual fertilization),the fertilizer amount reduced by 30%and the fertilizer amount reduced by 25%,and two riding modes of flatting and ridging were set up by field experiment to study the effects of reducing fertilization and ridging on peanut yield of variety Yuhua 22.Results showed that under conventional fertilization,the yield of peanut pod under ridge planting was not significantly higher than that under flat planting.Under flat planting,the yield of peanut pod under ridge planting was significantly higher than that under conventional fertilization,the yield of peanut pod was significantly reduced by 25%fertilizer reduction,but the effect of 25%fertilizer reduction on the yield of peanut pod was not significant.Results showed that reasonable reduced fertilization and ridging can not only reduce fertilizer input and production cost,but also reduce soil nutrient residue.
