潮褐土是北京农业地区的重要土类之一,它不但分布面积广而且肥力差异大。本文是研究三种混合肥料(普通型、高磷型、缺钾型)在潮褐土的三种肥力水上,对大麦的反应,对大麦籽粒品质的影响,大麦对混合肥料中养分的利用率。同时还探讨了混合肥料中大量养分与微量养分的相互关系,利用硝基腐植酸铵作载体配制有机一无机混肥的可能性。
Cinnamon is one of the most important soil types in Beijing’s agricultural areas. It not only has a wide distribution but also has great differences in fertility. This article is to study the effects of three kinds of compost (common type, high phosphorus type and potassium deficiency type) on the three fertility waters of moist cinnamon soil, the response to barley, the grain quality of barley, the nutrient utilization rate of barley . At the same time also discussed the relationship between a large number of nutrients and trace nutrients in the compost, the use of nitro humic acid ammonium as a carrier to prepare the possibility of organic-inorganic fertilizer.
