从八十年代初开始,我们在所内设置大麦施用有机无机氮不同配比定位试验,并在东台、大丰两县建立试验示范基点,研究有机无机氮肥不同配比对大麦增产效果,及对土壤肥力的影响。现将试验结果整理如下。
Since the early 1980s, we have set up barley different proportioning experiments of organic-inorganic nitrogen in our institute and set up demonstration bases in two counties of Dongtai and Dafeng to study the effects of organic and inorganic nitrogen fertilizers on yield increase of barley, Fertility effects. The test results are summarized below.
