摘 要:在江苏省西瓜甜瓜重点产区的苏南、苏中和苏北地区7个市瓜地采集了38个土壤样本,对土壤肥力状况进行了调查研究,结果表明:全省西甜瓜地土壤pH值平均为7.63,整体处于中性水平;土壤有机质和全氮平均含量分别为23.14、1.28 g·kg-1,均处于中等水平;土壤速效磷平均含量为45.66 mg·kg-1,处于很丰富水平;土壤速效钾平均含量为150.10 mg·kg-1,处于丰富水平;有效锌平均含量为1.94 mg·kg-1,处于丰富水平;而土壤有效硼平均含量为0.14 mg·kg-1,处于很缺乏的水平。因此,在培肥地力上应增施有机肥,适当降低磷肥的施用;此外,还应重视微量元素有效硼的施用。38 watermelon and melon soil samples were collected from seven cities in Jiangsu Province which are the key watermelon and melon production areas of the southern, central and northern Jiangsu. The obtained results showed that average soil pH was 7.63. The average soil organic matter and total nitrogen contents were 23.14 g/kg, 1.28 g/kg, respectively. The average soil available phosphorus was 45.66 mg/kg, a very rich level. The average content of available potassium was 150.10 mg/kg,a rich level. The average soil available zinc was 1.94 mg/kg,a rich level. The average soil available boron was 0.14 mg/kg, a very deficient level. In order to improve soil fertility, the application of organic fertilizer should be increased and the application of phosphate fertilizer should be reduced. In addition,extra attention should be paid to the application of mi- croelements fertilizer, such as boron.
