摘要
试验利用根际培养箱中猪粪与化肥配合施用培养小麦幼苗,通过测定植株和根际土壤中的养分含量,研究化肥、猪粪配施对小麦根际微区养分的空间效应。结果显示,猪粪、化肥配施的小麦对氮、磷、钾的吸收更好,且根际周围形成亏缺区,配施处理对小麦生长较纯施化肥显著提高。
Root is an important organ of plant to obtain nutrients and water from soils.Rhizospheric nutrition is an important field in recent years.Therefore,present experiment was carried out to study the spatial nutrient effects produced by combination fertilization of pig manure with chemical fertilizer in the rhizosphere of wheat by us root culture chamber.In the study,nutrients in the seedlings and the rhizosphere were measured.The absorptions of nitrogen,phosphorus and potassium by wheat seedlings were highest in combination fertilization of chemical fertilizer and pig manure,plant height and biomass were found in blank and chemical fertilization treatment.
