Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] The following is a detailed introduction by taking the detection of stripe rust in winter wheat as an example.

[0020] Using Xuezao, a variety sensitive to stripe rust, 98-100, a general susceptible variety, and Jing 4113, a relatively disease-resistant variety, under natural conditions, artificially inoculated with stripe rust on the diseased area and the normal growth control area. The winter wheat single leaf spectrum, canopy spectrum, physiological parameters, agronomic parameters and other factors have been deeply and systematically analyzed, and the main conclusions are as follows:

[0021] Firstly, the study found that the physiological parameters and agron...

Abstract

The invention discloses a disease detector, comprising a micro-processor for receiving and processing the signal from an incidence sensor and a reflection sensor; a power unit connected with the micro-processor and for providing power for the micro-processor; an incidence sensor connected with the micro-processor and for converting the incident light of sensitive wave-band corresponding with the disease index of the crop to be tested into the incidence electric signal and transferring the incidence electric signal into the micro-processor; a reflection sensor connected with the micro-processor and for converting the reflection light of sensitive wave-band reflected from the crop to be tested and corresponding with the disease index of the crop to be tested into the reflection electric signal and transferring the reflection electric signal into the micro-processor; a display unit connected with the micro-processor and for displaying data information processed by the micro-processor. The disease detector can quickly, reliably diagnoses the crop disease state on the spot at real time and be widely applied for the diagnosis of the crop disease, agriculture production and research.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a disease detector and a detection method thereof. Background technique [0002] Due to the development of modern industry and agriculture, the ecological conditions for crop growth have been greatly damaged, the ecological food chain has been destroyed, and the disasters of crop diseases and insect pests have become increasingly serious. The impact and harm on agricultural production are quite alarming. According to statistics, crop diseases and insect pests can reduce the world's agricultural harvest by 1 / 3. [0003] Wheat stripe rust is an important disease that endangers wheat production for a long time. It has a wide range of occurrence, strong prevalence, and serious damage. Once it breaks out, if it is not discovered in time and treated in time, it will cause disastrous consequences. Therefore, it has long been a cultivator. , breeders, pathologists, and plant protection expert...
