Background: Nitrogen (N), phosphorous (P), and potassium (K) are critical nutrient elements necessary for crop plant growth and development. However, excessive inputs will lead to inefficient usage and cause excessive nutrient losses in the field environment, and also adversely affect the soil, water and air quality, human health, and biodiversity. Methods: Field experiments were conducted to study the effects of controlled-release fertilizer (CRF) on seed yield, plant growth, nutrient uptake, and fertilizer usage efficiency for early ripening ...

目的:氮(N)、磷(P)和钾(K)是作物生长发育所必需的营养元素。然而,过度地投入会导致田间低效的利用率,造成大量养分损失,影响土壤、水和大气的质量,以及人类健康和生物多样性。因此,本实验研究控释肥料(CRF)是否可以替代可溶性肥料(SF),有效地增加作物产量,提高肥料利用率,减少田间养分损失。创新点:连续2年(2011~2013年)在中国南方红黄壤地区开展田间试验,研究控释肥料对早熟油菜(湘杂油1613)的产量、生长、养分吸收和肥料利用率的影响。可更好地解决稻?稻?油生产过程中的季节矛盾,简化油菜生产模式,增加农民收入,并确保国家粮油安全。方法:设置SF和等量CRF五个施用量处理,即SF1/CRF1 (3750 kg...
