校园基地土壤理化性质及其改良对策

试验测定了校园基地土壤耕层的一般理化性状,得出如下结论:①花卉基地、菜地土壤结构较好,富含有机质、水解性氮、速效磷,这是多年培肥改土的结果。②蓍草园、桃园土壤有机质含量不高,缺少速效钾。经改良可进一步利用。③学生宿舍院内荒地理化性状均差,目前不宜直接利用。同时提出了相应的土壤改良措施。

THE PHYSICAL AND CHEMICAL PROPERTY OF THE CAMPUS BASE SOIL AND RECLAMATION CONNTER-MEASURE

Through determining the physical and chemical status of the plough layer of the Campus Base soil, we have drawn the following 3 conclusions: (1) The soil structure of the flower base and the vegetable base is better and it is full of organic matter., hydrolyzable nitrogen and rapidly available phosphorus. The result relies on soil reclamation of many years. (2) The organic matter content of the yarrow-land and the peach-orchard is lower, moreover, the soil is lack of ex-changable potassium. It won't be used until the soil is improved in advance. (3) The state of chemical and physical of the wasteland nearby the yard of the student apartment is so bad that the wasteland might not be used directly at present. Then we have presented the adaptable soil reclamation measure as well.
