Apparatus and method for fine measurement of new plant root system improving soil infiltration effect

Abstract

The invention discloses a device and method for finely measuring the penetration effect of new plant roots improving soil, which comprises a stable water supply device, a constant pressure device, a planting frame, a bottom plate, a leveling device and an automatic weighing device. The stable water supply device is a cylindrical container, and the constant pressure device and the planting frame are fixed with screws, and the constant pressure device ensures that the water head of a certain thickness is maintained on the planting frame. The planting frame is filled with the soil to be tested, and plants are planted, and the bottom plate is fixed on the leveler. The automatic weighing device is placed on the base of the leveler, accepts the amount of water seeping from the planting frame, and automatically measures the total amount of water seepage and the rate of infiltration. At different stages of the plant growth process, the weighing device can automatically measure the total water seepage and infiltration rate of the planting frame, and compare and analyze the growth of the new root system after planting, and accurately evaluate the improvement of the soil soil pores by the amount of the new plant root system It can be used to measure and evaluate the influence of new root systems of different plants and different growth stages of the same plant on soil pores.

Description

technical field [0001] The invention relates to a technology for improving soil physical properties by plants, in particular to a fine measuring device and method for improving soil penetration effect of new plant roots. Background technique [0002] It is well known that plant roots can improve the soil, especially the voids formed after the death of the roots can greatly increase the soil porosity and improve the permeability of the soil, so that more rainwater can penetrate into the soil, so as to prevent soil erosion and conserve water sources. . [0003] However, the new plant roots will inevitably squeeze and occupy the existing soil pores during the growth process, and new pores may also be formed during the squeezing process. So whether the new plant roots increase soil pores, improve soil permeability, or New plant roots reduce soil porosity and deteriorate soil permeability. There is no accurate measurement and evaluation method at present. SUMMARY OF THE INVENT...

Problems solved by technology

[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 The newly born plant roots reduce soil porosity and deteriorate soil permeability. Currently, there is no accurate measurement and evaluation method
