[目的]筛选适宜在庐江县种植的早熟糯稻品种。[方法]从周边种植单位引进12个中早熟糯稻品种,各品种均设2个播种期,分析比较2种播期下各参试品种的生育期、田间性状、抗性及产量结构。[结果]正常在5月上、中旬播种的参试糯稻品种,提前至... 详细信息

[目的]筛选适宜在庐江县种植的早熟糯稻品种。[方法]从周边种植单位引进12个中早熟糯稻品种,各品种均设2个播种期,分析比较2种播期下各参试品种的生育期、田间性状、抗性及产量结构。[结果]正常在5月上、中旬播种的参试糯稻品种,提前至4月中、下旬播种,生育期延长,叶片、节间相对减少,有效穗数增加,成穗率降低,千粒重变轻,产量降低,抗倒性变差,水稻三大病害、穗发芽变重,综合抗性降低。[结论]从提早上市、增加经济效益和调优作物茬口考虑,根据参试品种的生育期、田间性状、产量结构等方面综合分析,光明糯1号是较为理想的水稻品种,适合在庐江县推广种植;其次是皖垦糯1号,早期播种产量高,但综合抗性最差,需要在种植期间加强稻瘟病等病虫害防治;籼型糯稻两优1674,适当迟播,避开抽穗开花期高温,加强稻曲病防治,也值得推广种植。

High-speed landslide is a catastrophic geological disaster in the mountainous area of southwest China. To predict the movement process of landslide reactivation in Chenjiaba town, Beichuan county, Sichuan province, China, we simulated the movement process of two landslide failures in Chenjiaba via rapid mass movement simulation and unmanned aerial vehicle images(UAV), and obtained the movement characteristic parameters of the landslides. According to a back analysis, the most remarkable fitting rheological parameters were friction coefficient(μ=0.18) and turbulence(). The parameter of landslide pressure was applied as the zoning index of landslide hazard to obtain the influence zone and hazard zoning map of the Chenjiaba landslide. Results show that the Duba River was blocked quickly with a landslide accumulation at the maximum height of 44.14 mwhen the Chenjiaba deposits lost stability. The hazard zoning map indicated that the landslide hazard degree is positively correlated with the *** landslide assessment is a quantitative hazard assessment method based on a landslide movement process and is suitable for high-speed landslide. Such method can provide a scientific basis for urban construction and planning in the landslide hazard area to avoid hazards effectively.
