Problems solved by technology
[0005] Aiming at the deficiencies of the prior art, the present invention provides: a study on the soil moisture inversion model of Lycium barbarum based on red edge parameters, which has the advantages of high detection feasibility, and solves the problem that the change of spectral reflectance of leaves of Lycium barbarum in different growth stages cannot be well detected. The influence of regularity and red edge characteristics cannot meet the problem of providing a theoretical basis for non-destructive and rapid monitoring of wolfberry soil moisture.

The invention relates to a Chinese wolfberry fruit soil moisture inversion model research based on red edge parameters, which comprises the following steps: 1, test material planting management and corresponding detection tests; 2, analysis of traditional red edge characteristics of different soil moisture; 3, lycium barbarum soil moisture analysis inversion; and 4, processing and summarizing of the whole data, wherein proper temperature and humidity is set in the corresponding garden field experiment base greenhouse, and potted Chinese wolfberry for the experiment is cultured. According to the Chinese wolfberry fruit soil moisture inversion model research based on the red edge parameters, the red edge position does not shift along with the change of the irrigation level by detecting different irrigation level conditions, and basically remains unchanged in the same growth period; secondly, the change rules of the red edge area Sdry, the red edge amplitude D lambda re, the red edge skewness D lambda re and the red edge kurtosis in each growth period are influenced by the irrigation level.
Description
technical field [0001] The invention relates to the technical field of wolfberry soil moisture inversion, in particular to research on a wolfberry soil moisture inversion model based on red edge parameters. Background technique [0002] Lycium barbarum is a characteristic agriculture in Ningxia Hui Autonomous Region. It has the characteristics of the same origin of medicine and food. It is a "red business card" for Ningxia facing the whole country and the world. In recent years, the demand for wolfberry has continued to grow, and the planting area of wolfberry in my country has also increased year by year. , by 2016, the planting area of wolfberry will reach 133,000 hm 2 , the planting area covers 13 provinces. The quality and output of wolfberry are not only affected by factors such as region, temperature and meteorological conditions, but also directly affected by soil moisture. The soil moisture content is closely related to the yield and growth state of wolfberry. Th...
