不同钾肥品种对加工番茄产量、品质和效益的影响

4R养分管理案例3 - 不同钾肥品种对加工番茄产量、品质和效益的影响 加工番茄的正常生长和高产优质需要大量的钾素营养,对钾的需求量甚至超过氮。用于番茄生产的钾肥品种主要有硫酸钾、硝酸钾和氯化钾。在生产中,种植者大多选用硫酸钾或硝酸钾,因为他们害怕氯化钾中的氯离子会影响番茄生长和品质,特别是在干旱地区。Chapagain 等 (2003)的研究指出,在加工番茄 .

新疆加工番茄生产中4R 钾肥管理措施

新疆是我国加工番茄主要生产和加工基地,番茄种植面积由2001年的33万亩,增加到2010年的140万亩,产量已达500万吨。新疆光照充足、昼夜温差大、湿度低等有利于加工番茄生长和干物质积累。加工番茄的正常生长需要大量的钾素营养,对钾的需求量超过氮。然而传统上认为在新疆灰漠土上钾充足,从而导致农民长期不施用钾肥,造成土壤钾素耗竭,土壤有效钾含量下降,从而.
