“…The statistics show that the maximum value of RMSE is 12.65%, the minimum value is 3.49%, and the average value is 5.48%. 25 As can be seen from the figure, the value of RMSE changes irregularly from 350 to 2,500 nm. At 350 nm, the value of RMSE is 7.41%, and then RMSE decreases with the increase of wavelength.…”

In order to improve the yield of crops, the method of soil water content detection and analysis based on experimental reflectance spectrum data is adopted. From the four aspects of the farmland soil water detection based on reflection spectrum information, soil water content detection in farmland based on spectral absorption characteristics, remote sensing inversion of soil water content of farmland by reflectance spectra data, and soil water content detection in farmland based on near‐infrared spectroscopy, the soil water content of farmland can be analyzed. The absorption valley near 1,920 nm is the characteristic absorption valley of soil water in the black soil, which can be used to predict the water content of the black soil by the spectral characteristic parameters of the absorption valley; soil water will increase the absorption of radiation energy and reduce the overall reflectance spectra of soil. The quantitative monitoring of soil water content can be achieved by using the remote sensing model of soil water content in this paper. In the range of low soil water content, the reflectance decreases with the increase of soil water content in farmland, whereas in the range of high soil water content, it increases with the increase of soil water content in farmland. The correlation between soil water content and normalized spectral reflectance is positive and negative correlation and mainly negative correlation. The method can detect soil water content in farmland under extreme conditions of different texture, soil water, salinity, and organic matter. It is an effective method for soil water content detection.

<p>Hydrological and ecological role of wetlands were growing significant. Based on Landsat satellite remote sensing data collected in the years of 1990, 2000 and 2014, and integrating GIS with analytical methods of landscape ecology, research on changes of land use/cover and landscape pattern of Zhalong Wetland from 1990 to 2014 was conducted. Then, we analysed the effect of human activities and climate changes on land use/cover. The main conclusions were as follows: (1) Significant changes in land use/cover have taken place in Zhalong wetland during 1990-2014.Cultivated land, unused land and construction land increased continually, while the area of reed swamp, water swamp, grass land and water land decreased accordingly; (2) Landscape patch shape has be increasingly irregular and turned complexed, there was the tend of the growing diversification and homogenization of land use change and the growing complicate landscape pattern in Zhalong wetland; (3) There was a warm-dry climate trend from 1958 to 2014; (4) Human activities including population, construction, water land pollution and production have been threatening the wetland ecosystem. Those changes in Zhalong area were caused by nature and human activity. However, the human’s contributions are great.</p>

“…Peanut (Arachis hypogaea L.), a member of the legume family Fabaceae native to South America and an economically important crop in several countries, is grown mainly for its edible seed, which are rich in vitamins and nutrients, have high oil (49.66%) and protein (24.35%) content, and can be processed and used as an animal feed or as human food in the form of peanut butter, salted nuts, and snacks (Bonku & Ju, 2019). In addition to these uses, the oil extracted from the seed can be used for biodiesel production as an alternative to other vegetable oils such as soybean, sunflower, coconut, palm, rapeseed, and cotton (Shalmashi & Khodadadi, 2018).…”

Peanut seed can be infected by pathogen diseases that adversely affect the oil crop’s value chain. Ozone gas (O3) can be an alternative for the control of fungal diseases due to its high oxidizing potential. In this study, we investigated the effects of O3 exposure time on physiological and health characteristics of seed from three peanut cultivars. Seed from peanut cultivars Granoleico, IAC OL3, and IAC 503 were analyzed for their health (blotter test) and physiological potential (germination, first count, and seedling length) after exposure to O3 for 0, 1, 8, and 16 h. Peanut seed physiological quality and health differed among cultivars. Exposure of seed from peanut cultivars IAC OL3, IAC 503, and Granoleico to O3 at a rate of 600 mg h-1 did not affect the development of normal seedlings as measured by the first count and germination, but seedling length increased, decreased, or was not affected in cultivars Granoleico, IAC 503, and IAC OL3, respectively. Also, O3 did not eradicate fungal infections in peanut seed treated with O3 at a rate of 600 mg h-1 for up to 16 h, but the incidence of the fungus Rhizopus sp. in seed from cultivars IAC OL3, Granoleico, and IAC 503 increased, decreased or was not affected, respectively, after 8 h.
