本文在分析讨论四川紫色土、黄壤中硼、锌含量状况及其影响因素的基础上,对它们的丰缺趋势进行了评价。指出这两类土壤均系缺硼土壤;缺锌的差别甚大,紫色土比黄壤普遍。据此提出因地制宜地推广应用硼、锌微肥的建议。 Based on the analysis of the contents of boron and zinc in the purple soils and the yellow soils of Sichuan Province and their influencing factors, this paper evaluates the trends of their abundance and deficiency. It is pointed out that these two types of soils are all deficient in boron-deficient soils; the difference in zinc deficiency is very large, and purple soils are more common than yellow soils. Proposed according to the local popularization and application of boron, zinc fertilizer recommendations.
