速测土壤养分新技术———树脂膜插长期以来，传统的土壤养分测定方法需从田间用土钻多点取样、室内风干、浸提过滤，最后测定养分含量。工序繁琐，劳动量大。树脂膜插技术直接应用于大田是９０年代初期加拿大首先发展。树脂膜插技术（以下简称膜插技术）在浸提土壤养分的... Rapid testing of soil nutrients a new technology --- membrane plugging period, the traditional method of determination of soil nutrients from the field with multi-point sampling with earth-drilled, indoor air-dried, leaching and filtering, and finally determine the nutrient content. Tedious process, a large amount of labor. Direct application of resin membrane technology in Daejeon was first developed in Canada in the early 1990s. Resin membrane technology (hereinafter referred to as membrane technology) in the leaching of soil nutrients ...
