据《Scientia Horticulturae》的一篇研究报道(doi:10.1016/j.scienta.2016.05.002),来自巴西圣玛利亚联邦大学的Gustavo Brunetto等人研究了不同时间施用不同量的尿素15N氮肥对葡萄营养的作用。巴西种植于沙地的葡萄园,氮肥(N)应当在适当时期(需求量最大的时候)适量施用,从而减少N流失。本研究评估了葡萄N分布及发芽期和开花期施用15N后的营养恢复情况。2009年研究人员在巴西南部圣安娜—利
According to a study by Scientia Horticulturae (doi: 10.1016 / j.scienta.2016.05.002), Gustavo Brunetto et al from the Federal University of Santa Maria in Brazil studied the effect of applying different amounts of urea 15N nitrogen fertilizer on grapes The role of nutrition. In vineyards planted in sandy land in Brazil, nitrogen (N) should be applied in moderation (at the time of peak demand) to reduce N losses. The present study evaluated the N distribution of grapes and the nutritional recovery after 15 days of application at the germination and flowering stages. 2009 researchers in Santa Ana - south of Brazil
