Rob Mikkelsen著, 谢玲 译 涂仕华 校 想要获得作物高产，良好的开端是关键。在其作物生长的早期阶段，幼苗特别容易受到多种环境和生物胁迫的影响。为了使作物免受环境胁迫和病害困扰，从播种到收获都必须保证均衡营养。随着我们对植物健康前沿研究的不断深入和了解，植株营养和抗病性之间的关键联系也更加清晰可见。本文可提供以下一些例证： 钾 钾在植物很多人们熟o.

加工番茄的4R钾肥管理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.
