作者（2019）在《Status of Soil Nutrients in Citrus Orchards of Guangxi》一文中研究指出：Based on the investigation of 56 soil samples( 0-30 cm) in citrus orchards of Guangxi,the content of soil organic matter and available nutrients as well as their correlations in the citrus orchards were studied. The results showed that soil was rich in organic matter,and the proportion of soil samples deficient in available N,P and K was 30. 36%,32. 14% and 28. 57% respectively. Soil was seriously deficient in soil available Ca,Mg and B,while the content of soil available Fe and Cu in soil was too high. There were significant or extremely significant positive or negative correlations between soil pH,organic matter and several available nutrients. It is recommended to apply Mg fertilizer,B fertilizer,lime or other alkaline fertilizer and reduce the spraying of fungicides containing Cu in the citrus orchards.

Soil was seriously deficient in soil available Ca,Mg and B,while the content of soil available Fe and Cu in soil was too high. There were significant or extremely significant positive or negative correlations between soil pH,organic matter and several available nutrients.
