摘要
本研究对澄迈县主要辣椒种植乡镇0~20 cm土层进行取样与测定。结果表明,澄迈县土壤交换性钙、交换性镁含量缺乏,土壤有效硫、有效铁、有效锰、有效铜、有效锌及有效硼含量较丰富。区域内土壤交换性钙含量处于四级、五级水平的样品占83.3%,土壤交换性镁含量处于三级及以下水平占比88.0%,土壤有效硫、有效铁、有效锰、有效铜、有效锌、有效硼处于三级及以上水平的占比分别为83.0%、98.9%、68.6%、100.0%、96.5%、91.3%。根据调查结果,应重视钙肥、镁肥的施用。
The soil nutrition contents within 0 to 20 cm depth of pepper planting area in Chengmai County were investigated in this paper. The results showed that,in Chengmai County, the content of exchangeable calcium and exchangeable magnesium in soil was poor, the content of available sulfur,available iron,available manganese,available copper,available zinc and available boron was rich. Exchangeable calcium in 83.3% of the soil samples was in fourth and fifth level, and exchangeable magnesium in 88.0% of the samples was in level of third or below. The proportion of soil nutrition in level of third or above was available sulphur （83.0%）, available iron （98.9%）, available manganese （68.6%）, available copper （100.0%）, available zinc （96.5%）, available boron （91.3%）.According to the survey, the fertilizer attention should be paid to the deficiency of calcium and magnesium in the soil.
