良好的营养是植物健康的关键

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.

今天的氮肥管理与你父辈时代不同

Cliff Snyder著, 谢玲 译 涂仕华 校 我们有很多上了年纪的人可能还记得那些苦难的年代,父辈们日夜劳作,也只能从地里收回些许粮食;因为这些土地从祖父们开始,就一直管理不善。很多现代农民面对的是另外的问题,继承了过度或“休闲”土壤耕作的遗产,以及满足于最佳土壤肥力管理与实施最佳保护性耕作的遗产。现在无人耕种的土地面积比例很高,这使一个农民除了收║.

钾肥的来源与品种

Mike Stewart著, 谢玲 译 涂仕华 校 农业中的钾(K)通常泛称为钾碱。术语钾碱是来源于早期一种生产技术,那时K是用水过滤柴灰,滤液置于铁锅中经水分蒸发而得到。这种方法是依靠树木的根系从土壤中吸收矿物K,然后将树木砍下燃烧获取。得到的K是碳酸钾,它被用作肥料以及用于生产玻璃和肥皂等。有趣的是,美国授权的第一个专利是生产钾肥(1790)。在那个年代,收集 .

改善土壤中移动性差养分在田间分布的策略
