Background

The bleeding sap is the sap of the conduction tissue of the plant wound, and is transported to the ground through the conduction tissue under the action of root pressure and transpiration pull force; the injury flow of the plant root system is an important expression of the strength of the root system activity, and can better reflect the conditions of plant root system absorption, root system metabolism and root system activity. In recent years, plant bleeding fluid composition analysis has been attracting attention, and plays an important role in growth and stress response as signal molecules in underground and overground parts. Therefore, the collection and research of the bleeding sap of plants are particularly important.

At present, the collection device of the bleeding sap is mainly a simple collection method introduced by referring to Jinchengzhi and the like, a section of glass tube with an opening and a section of closed glass tube is selected, and the bleeding sap is collected by a method that absorbent cotton is filled in the glass tube, and a plastic sealing bag is also used for collecting the bleeding sap instead of the glass tube.

However, the glass tube is fragile and not easy to store, and the glass tube is heavy, often influences the outflow of the bleeding sap due to weight pressure, and the leakproofness is not good, and the bleeding sap is volatile, and the inner wall easily forms water droplets. The plastic bag is easy to fall off, and the bleeding liquid is not easy to be preserved. The method for recovering the bleeding sap mostly adopts an extrusion method, absorbent cotton absorbing the bleeding sap is placed into an injector, and the fluid is manually extruded. Therefore, it is necessary to design a device for collecting and recovering the plant bleeding liquid.
