Abstract

The invention discloses a plant root absorption data collection device and method, including a positioning tube, a nutrient maintenance part, a filling body and a detachable circulation structure. The positioning tube is composed of a symmetrical left half tube and a right half tube. The shell of the maintenance part is formed with a maintenance cavity, which is filled with an aqueous solution for plant roots to maintain normal survival. The filling body is a porous sponge. The detachable circulation structure includes a liquid injection pump, a quantitative solution bottle, a circulation tube and an air pump. The invention can accurately measure the amount of a certain element absorbed by plant roots within a certain period of time in situ, and provides important data support for plant soilless cultivation.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a device and method for collecting data of plant root absorption. Background technique [0002] Fertilization refers to the agricultural technical measures that apply fertilizer to the soil or spray it on the plants to provide the nutrients needed by the plants and maintain and improve the soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, fertilize soil and improve economic efficiency. Therefore, rational and scientific fertilization is one of the main means to ensure food security and maintain sustainable agricultural development. [0003] Fertilization is mainly based on soil fertility level, crop type, target yield, climatic environment and fertilizer characteristics, so as to select suitable fertilizers, estimate the amount of fertilizer required, and determine the time and mode of fertilization. According to th...
