| [surveillance on contamination of total aflatoxins in corn, peanut, rice, walnut and pine nut in several areas in china]. | to realize the contamination of total aflatoxins in corn, peanut, rice, walnut and pine nut in china, and provide the base data for establishing a china tolerance limit standard and an international control practice for total aflatoxins. | 2006 | 16620597 |
| contamination of aflatoxins in different kinds of foods in china. | to study the contamination of total aflatoxins (afs) in different kinds of foods including corn, peanut, rice, walnut, and pine nut in six provinces and two municipalities in china. | 2007 | 18348407 |
| mycorrhizal colonization status of lowland rice (oryza sativa l.) in the southeastern region of china. | the accumulation, distribution, and speciation of contaminants, such as arsenic, in rice can be affected by soil microorganisms such as arbuscular mycorrhizal fungi (amf). as a potential measure to control contaminant acquisition in rice, the status and performance of amf in the field need to be investigated. root samples of rice plants were collected in seven different cities in guangdong, jiangxi, hubei, and jiangsu provinces in china in order to investigate the colonization rate of amf. the t ... | 2017 | 28004369 |
| [cycling and balance of copper in farmland ecosystem of jianghan plain in hubei province]. | the cycling and balance of copper in 8 cropping systems, i.e., wheat-rice, rice-rice, rape-soybean, rape-peanut, wheat-sesame, wheat-cotton, pepper-cabbage and radish-eggplant in jianghan plain of hubei province were studied. the results showed that the main output of copper was crop harvesting, up to 85.9%-95.1% of total output, and the output of copper by field runoff and soil leaching was low. the main inputs of copper were organic fertilizer, rainfall, falldrop, and natural return. the input ... | 2003 | 12722442 |
| chemical forms of selenium in corn and rice grown in a high selenium area of china. | the chemical forms of selenium were determined in maize grown near yutangba village and in rice grown near haubei village, exi prefecture, enshi county of hubei province, china. the maize sample contained 18 ppm and the rice samples an average of 3.6 ppm selenium. after they were ground to obtain a fine flour, this was acid hydrolyzed with hydrochloric acid in an inert atmosphere and the hydrolyzates chromatographed on columns of dionex dc6a resin. the results indicate that the majority of the s ... | 1991 | 1781934 |
| [co2 fluxes from red soil under four land use types in mid-subtropical, china]. | co2 fluxes from red soil under different land use (paddy, upland, woodland and orchard) were measured at xianning city, hubei province with closed chamber method. the results showed that the annual co2 emission were 1129, 632, 533, and 828 g/(m2 a) for paddy, upland, woodland, and orchard respectively. soil co2 fluxes revealed seasonal fluctuations, with the tendency that maximum value was in summer, minimum was in winter and intermediate in spring and autumn except for paddy soil. co2 fluxes fo ... | 2007 | 17891977 |
