近几年来,我们对湛江地区的砂质田类进行了系统调查与试验研究,提出了利用改良砂质田类的途径,现整理如下。砂质田类的概况及分析砂质田类广泛分布于湛江地区各地,尤以雷北、电白、阳江及北部丘陵地带分布较为集中。据调查全区砂质田类(不包括砂质地)总面积为262.5万亩,占水旱田面积的40.7％,而占总耕地面积的28.64％。全区年亩产800斤以下的低产砂质田面积占120万亩左右,其中还有相当面积的砂质田年亩产在500斤以下,这说明改造砂质田类对湛江地区提高单产和增加总产的潜力是很大的。湛江地区砂质田类分布的地形是复杂的, In recent years, we conducted a systematic investigation and experimental study on the sandy fields in Zhanjiang, and put forward the ways to improve the sandy fields by using the following methods. Sandy Field Profile and Analysis Sandy fields are widely distributed in various parts of Zhanjiang, especially in northern Leibn, Dianbai, Yangjiang and northern hilly areas are more concentrated. According to the survey, the total sand area (excluding sandy area) of the whole area is 2.625 million mu, accounting for 40.7% of the total area of ​​dry land and 28.64% of the total cultivated area. The area of ​​low-yielding sandy mound with an annual output of less than 800 kilograms per year covers an area of ​​about 1.2 million mu, of which there is a considerable area of ​​sandy mound with an annual output of less than 500 kilograms per annum, which shows that the improvement of yield- The potential for increasing the total output is great. Zhanjiang sand sandy terrain distribution is complex,
