Fine measurement device and method for newly-born plant root system improved soil permeation effect

Abstract

The invention discloses a fine measurement device and method for improving the soil permeation effect of a new plant root system. The fine measurement device comprises a stable water supply device, aconstant pressure device, a planting frame, a bottom plate, a leveler and an automatic weighing device, wherein the stable water supply device is a cylindrical container, the constant pressure deviceand the planting frame are fixed through screws, the constant pressure device ensures that a water head with a certain thickness is maintained on the planting frame, the planting frame is filled withsoil to-be-measured, plants are planted in the planting frame, the bottom plate is fixed to the leveler, and the automatic weighing device is placed on a base of the leveler, receives the water seeping out of the planting frame and automatically measures the total water seepage amount and the seepage rate. The method is advantaged in that different stages in the plant growth process can be realized, the total water seepage amount and the seepage rate of the planting frame are automatically measured through the weighing device, after the planted plants are compared and analyzed along with the growth of new roots, the improvement effect of the new plant root amount on soil pores is accurately evaluated, and the method can be used for determining and evaluating the influence of the new rootsof different plants and the new roots of the same plant at different growth stages on the soil pores.

Description

technical field [0001] The invention relates to a technology for improving the physical properties of soil by plants, in particular to a fine measurement device and method for improving the infiltration effect of new plant roots. Background technique [0002] It is well known that the root system of plants can improve the soil, especially the void formed after the root system dies can greatly increase the soil porosity and improve the permeability of the soil, so that more rainwater can infiltrate into the soil, so as to prevent soil erosion and conserve water. . [0003] However, the new plant roots will inevitably squeeze and occupy the existing soil pores during the growth process, and may also form new pores during the extrusion process, so whether the new plant roots increase soil pores and improve soil permeability, or New plant roots reduce soil porosity and deteriorate soil permeability. Currently, there is no accurate measurement and evaluation method. Contents o...
