Corn stalk bleeding sap collection device

Abstract

The invention discloses a corn stalk bleeding sap collection device which comprises a dustproof cover, a centrifugal cover, a counterbalance cover and a collector; the dustproof cover is movably connected with a first port of the collector before centrifugal treatment of corn stalks and is used for preventing dust when the collector collects the corn stalks; the centrifugal cover is movably connected with the first port of the collector when centrifugal treatment of the corn stalks is performed; the counterbalance cover is in sealing connection with a second port of the collector; the collector is internally provided with a fixing layer; and the fixing layer is used for fixing the corn stalks when a corn stalk bleeding sap is collected. For the corn stalk bleeding sap collection device, when the corn stalks are collected, the dustproof cover is arranged, so that the collected corn stalks cannot be polluted; when the corn stalk bleeding sap is collected, the dustproof cover is replacedwith the centrifugal cover, and centrifugal treatment is performed; and in addition, during centrifugation, the counterbalance cover can be used for counterbalance with water, and the stability of centrifugal treatment is ensured, so that the corn stalk bleeding sap can be acquired to the maximum, and the accuracy of the detection result of the bleeding sap in the later period is facilitated.

Description

technical field [0001] The present application relates to the technical field of collecting plant wound sap, in particular to a device for collecting corn stalk wound sap. Background technique [0002] The maize root system not only fixes the plant body, uptakes, transports and stores nutrients, but also synthesizes a series of organic compounds ranging from major storage products and soluble metabolites to growth regulators. Part of the inorganic salts absorbed by plants undergoes primary assimilation in the roots, transforms into organic matter and transports them to the shoots. Injury fluid is the juice of the transporting tissue of plant wounds, which is transported from the ground to the ground through the transporting tissue under the action of root pressure and transpiration pull. Plant root injury flow is an important manifestation of root vitality and can better reflect Plant root absorption, root metabolism and root activity, and the determination of the types and...

Problems solved by technology

[0004] However, there are still many irrationalities in these methods in the past. The "direct collection method" is beneficial to the period when the corn wound fluid is more, and has limitations; the "absorption method" wound fluid is absorbed into the absorbent cotton and then squeezed out. It is easy to leave absorbent cotton and cause pollution; the "negative pressure / pressurized collection method" has relatively high technical requirements, and the required equipment is relatively cumbersome and inefficient

In addition, there are methods such as micro-injury phloem to collect wound fluid, but it is only suitable for dicotyledonous plants such as cotton, not for monocotyledonous plants such as corn

Extrusion method is often used for the recovery of wound fluid. The absorbent cotton that has absorbed the wound fluid is put into the syringe, and the liquid is manually squeezed out. This method is labor-intensive, low recovery rate, and time-consuming.
