锰是植物正常生长发育不可缺少的微量营养元素之一。锰的供给不足,会影响农作物产品的品质及产量。锰肥的效果取决于土壤、肥料、作物三者间的关系。研究济南地区主要土壤类型的锰含量及锰肥肥效,对于评价该地区土壤中锰的丰欠、锰肥的使用和推广,都具有一定的价值。济南地区除棕壤略有分布以外,大部分是石灰性土壤。我们根据石灰性土壤的分布面积
Manganese is one of the essential micronutrients for the normal growth and development of plants. Inadequate supply of manganese can affect crop product quality and yield. The effectiveness of manganese fertilizer depends on the soil, fertilizer, crops, the relationship between the three. Studying the manganese content of main soil types in Jinan area and the fertilizer efficiency of manganese fertilizer are of certain value for evaluating the manganese deficiency in the soil and the use and promotion of manganese fertilizer in this area. In addition to a slight distribution of brown earth in Jinan, mostly calcareous soil. We are based on the distribution area of calcareous soil
