The neutral filtering mud produced in the low-temperature phosphor floating method can be directly used as fertilizer. 低温磷浮法产生的中性滤泥可以直接用作肥料或进一步提取高附加值产品。
Neutral aroma components and flavor quality in flue-cured tobacco leaf in the west of Henan Province under the zinc fertilizer were studied. 从评吸评价结果看,锌促进了豫西烤烟下部和中部叶片香气质量的提高。
Compared with different N fertilizer treatments, the quantities of the neutral insect, the natural enemy and the pest in the 16 kg/ 667m~ 2 N fertilizer treatment is more than that of the other treatments. 通过比较不同N肥施用水平发现,16kg/667m~2N素处理害虫数量较多,中性昆虫和天敌数量也更多。
Effect on Nutrient Release Characteristics of Neutral Compound Slow Release Fertilizer by Sand Soil pH 砂质土壤pH对中性缓释复合肥养分释放特性的影响研究
The contents of the total neutral aroma components, middle leaves of every treatment, increased first and then decreased with the increase of nitrogen fertilizer rate, indicating that too much nitrogen fertilizer was not conducive to the formation of burley aroma. 各处理中部叶总中性致香成分含量随施氮量的增加呈现出先增加,后又有所降低的趋势,说明过多的氮肥用量不利于白肋烟香气物质的形成。
