Description
技术领域 technical field
本实用新型涉及一种土壤碱解性氮的扩散皿，属于实验器材技术领域。 The utility model relates to a diffusion dish for soil alkali-degradable nitrogen, which belongs to the technical field of experimental equipment.
背景技术 Background technique
目前，土壤碱解性氮测定方法：称取风干土，将其均匀地置于扩散皿外室，取2%硼酸指示剂溶液放于扩散皿内室，然后在扩散皿外室边缘涂上碱性胶液，盖上毛玻璃，旋转数次，使皿边与毛玻璃完全粘合。再渐渐转开毛玻璃一边，使扩散皿外室露出一条狭缝，迅速加入氢氧化钠溶液，立即盖严，再用橡皮筋圈紧，使毛玻璃固定，轻轻摇动扩散皿，使碱液与土壤充分混合。在操作过程中，制备碱性胶液及在外室边缘涂碱性胶，使得实验操作繁琐，胶液涂好后皿边与毛玻璃片旋转数次容易使扩散皿内的溶液污染，返工率高，对操作人员的技术水平要求高，影响工作效率。 At present, the method of soil alkaline hydrolysis nitrogen determination: take air-dried soil, place it evenly in the outer chamber of the diffusion dish, take 2% boric acid indicator solution in the inner chamber of the diffusion dish, and then coat the edge of the outer chamber of the diffusion dish with alkali Cover with frosted glass and rotate several times to make the edge of the dish and the ground glass completely bonded. Then gradually turn one side of the frosted glass to expose a slit in the outer chamber of the diffusion dish, quickly add sodium hydroxide solution, immediately cover it tightly, and then tighten it with a rubber band to fix the frosted glass, and gently shake the diffusion dish to make the lye and soil Mix well. In the process of operation, the preparation of alkaline glue and the application of alkaline glue on the edge of the outer chamber make the experimental operation cumbersome. After the glue is coated, the edge of the dish and the frosted glass are rotated several times to easily pollute the solution in the diffusion dish, and the rework rate is high. The technical level of the operator is high, which affects the work efficiency.
