摘要
本文系统地阐述了青贮玉米施肥的理论与技术,内容包括青贮玉米养分需求规律、土壤养分供应规律、肥料养分含量、肥料当季利用率、施肥量确定方法、青贮玉米土壤养分丰缺指标推荐施肥体系、测土定肥、施肥原则、施肥时期、施肥次数、施肥方法等。
The fertilization theory and technology of silage corn were systematically explained in this paper. The content include nutrients requirement law of silage corn, nutrients supply law of soil, nutrient contents of fertilizer, fertilizer use efficiency in current season, determining method of fertilizer application rate, fertilizer recommendation system based on soil nutrient abundance-deficiency index for silage corn, soil testing and fertilizer recommendation, fertilization principle, fertilization period, fertilization frequency, fertilization method, etc.
