Abstract

The invention discloses crops nitrogen element nutrition diagnostic equipment, which comprises a crops canopy information measure module, a mobile terminal and a remote server, the remote server comprises a fixed IP address for receiving the measure data of the reception mobile through GPRS transmission; the crops canopy information measure module is composed of a microcontroller, a sunshine light intensity detector, a canopy reflected light detector, a lithium battery power supply module and a bluetooth module. The microcontroller comprises two IIC interfaces, six analogue I/O interfaces, a digital I/O interface and a serial communication interface connected to the bluetooth module. The microcontroller is connected to the lithium battery power supply module through the digital I/O interface and is capable of controlling the lithium battery power supply module. A diagnosis method is divided into five steps. The method can rapidly measure the nitrogen concentration, biomass and nitrogen element nutrition index information of crops in a nondestructive mode, and measurement point latitude and longitude, crop nitrogen element nutrition lack level and fertilization suggest can be given. The crops nitrogen element nutrition diagnostic equipment has important meaning for accurately managing a nitrogenous fertilizer for crops, increasing fertilizer utilization rate, and reducing environmental pollution.

Description

technical field [0001] The invention relates to a nutritional diagnostic instrument and a method, in particular to a crop nitrogen nutritional diagnostic instrument and a method, and belongs to the technical field of vegetation remote sensing testing. Background technique [0002] Nitrogen is an important nutrient element necessary for crop growth and development. In order to ensure the yield, farmers often apply excessive nitrogen fertilizers to the fields; indiscriminate application of nitrogen fertilizers not only reduces farmers' income, but also causes environmental pollution. Therefore, there is an urgent need to quickly and non-destructively obtain the nitrogen nutrition status of crops, and apply nitrogen fertilizers accurately and quantitatively according to the nitrogen fertilizer requirements of crops themselves. [0003] At present, the instruments for quickly testing the nitrogen nutrition status of crops can be roughly divided into two categories: one is reali...
