Abstract

The invention provides a root droplet attachment area detection device and method based on low-field nuclear magnetic resonance and optical fiber detection. The device comprises a spraying module, a low-field nuclear magnetic resonance detection system and a water film thickness optical fiber detection module, wherein the spraying module comprises a liquid supply device, a drain pipe, a water supply pipe, a movable joint, an atomizing nozzle, an isolation sheet, a movable baffle and a detachable sealed spraying cavity. Data are collected through the low-field nuclear magnetic resonance detection system and the water film thickness optical fiber detection module, the root droplet attachment area is calculated, whether droplets are uniformly distributed is determined, accurate control and adjustment of spraying are facilitated, and reasonable supply of oxygen, nutrients and water to crop roots is achieved; the economic benefit of crops is improved, a new technical means is provided for solving the problem of imbalance of the root-to-crown ratio of atomization cultivation crops, shortening the growth period and increasing the overall proportion of available stems and leaves, and the detection device and method can be widely used in the market.

Description

technical field [0001] The invention belongs to the field of agricultural engineering, and in particular relates to a detection device and a detection method for root system droplet adhesion area based on low-field nuclear magnetic resonance and optical fiber detection. Background technique [0002] Atomization cultivation is the most practical cultivation method in crop cultivation at present. The root system of crops is suspended in the air and can grow freely, with sufficient oxygen and well-developed root system. Obtaining water and nutrients in the most direct way can greatly increase the quantity and quality of production, and greatly reduce the input of manpower, fertilizer, water and pesticides. At present, atomization cultivation is the most potential and promising development in the field of agricultural production and research. technology. [0003] Most of the existing atomization cultivation techniques are based on the control of spray volume, droplet size, spra...
