Planned area is 340.9km~2 in the plan for Daqing of the Ha-Da-Qi Industrial Corridor,including saline land 320km~2.Based on grid datasets and map algebra,the sites selecting model is built in this article using the spatial analyst.
Yanjing68 is the high yield and quality rice which is breeded by Liaoning Province Saline or Alkaline Land Utilization and Research Institute, it was examined and approved by Liaoning Province variety examine and approve committee in 2003, it is better than liaojing294 on plant figure, yield, the yield on production is 650 kg/667 m2, it increase 10% than antitheses.
The generation T_5 of upland rice carried mtlD gene steadily and the generation T_2 of upland rice carried BADH gene steadily were cultivated in 0.5%-0.6% NaCl alkaline land in Dongying, Shandong province. Most of the transgenic upland rice could grow normally, while the nontransgene plants can not grow (upland rice 502).
Literature on utilizing alkali saline soil to grow fruit trees at home and abroad, salt tolerance of germplasm resources of different fruit trees, effects of salt stress on vegetative growth, fruit quality and physiological biochemical characteristics, as well as indices of salt tolerance identification is reviewed.
The characteristics of the infiltration, the salt content, salt concentration distribution, are studied through a series of experiments of the soil water movement and salt transport at laboratory in accordance with the characteristics of alkali saline soils and the concerning research results under one dimension water ponding infiltration at home and abroad. The results will provide some guidance for the utilization of the salt effected soil.
Detection of Coastal Saline Land Uses with Multi-Temporal Landsat Images in Shangyu City, China
rostrata is moderately salt tolerant and may be utilized as forage crop and green manure on saline land.
The frequent temporal and spatial transition in source class, grassland, alkali-saline land and irrigated cultivated land caused negative effects on the oasis environment.
To the extent new cropland can be developed from unused saline land, further land clearing and loss of C storage in forest fallow and old growth forests can be spared, thereby adding to the carbon sequestering potential of all usable ecosystems.
Feasibility Study of Salicornieae as Oil-seed Halophytes for Saline Land and Water.
The result shows that there were rapid increases in the area of cropland, saline-alkaline land, and dramatic decreases in grassland, water area and wetland between 1986 and 2002.
frigida steppe and eight non-grassland types: active cropland, harvested cropland, urban area, wetland, desertified land, saline and alkaline land, cloud, water body + cloud shadow.
The area of soil salt accumulation was greater in irrigated than in non-irrigated landscape types with an increasing of 40.04% from 1983 to 2005 in cropland at ～0.43?t ha-1 year-1, and an increase at ～0.68?t ha-1 year-1 in saline alkaline land.
