一、研究目的与方法据日本报导,烤烟施用硝基腐植质肥料能使烟株叶片减少,叶肉增厚,有害成分减少,能使烟叶达到优质品。1980年我所根据农业部土地利用局下达的试验设计方案在所外基点进行了田间试验,研究硝基腐钾、硝基腐氮磷肥料同进口复合化肥对春烟增产增质的效果,以便为推广提供科学依据。
First, the research purposes and methods According to reports from Japan, the use of nitro humus fertilizer flue-cured tobacco leaves can reduce the leaves, thickening of leaf meat, reducing the harmful components, can make tobacco to achieve high quality products. In 1980, according to the experimental design scheme issued by the Bureau of Land Utilization, Ministry of Agriculture, we conducted field experiments at other sites to study the effect of nitrotyrosine and nitrofurantosorb fertilizer on the yield and quality of spring tobacco with imported compound fertilizers so that To provide a scientific basis for promotion.
