中文摘要:为了探究寒地黑土区水稻植株干物质积累对耗水过程的响应规律,于2017年在黑龙江省水稻灌溉试验站的蒸渗仪内进行了水稻耗水试验。采用U7(76)均匀试验设计,深入解析了各生育阶段耗水量对水稻干物质量及干物质积累过程的影响。结果表明,各生育阶段耗水量对水稻干物质积累的影响决定系数由大到小依次为:抽穗开花期、拔节孕穗期与抽穗开花期的耦合效应、拔节孕穗期、抽穗开花期与乳熟期的耦合效应、分蘖中期与抽穗开花期的耦合效应、分蘖中期与拔节孕穗期的耦合效应、分蘖中期。在水稻营养生长阶段,各阶段耗水量通过影响干物质积累进入快速增长的时间和最快增长速率,进而间接影响干物质积累量,分蘖中期耗水量每增加1mm,将提前0.459d进入干物质积累快速增长阶段;拔节孕穗期耗水量每增加1mm,干物质积累的最快增长速率提高0.0113g/d。进入生殖生长阶段,各阶段耗水量对干物质积累量的直接影响大于间接影响。各生育阶段耗水量对水稻产量和干物质量的影响排序相同,由大到小依次为:抽穗开花期、拔节孕穗期、分蘖中期、乳熟期、分蘖前期、分蘖后期,拔节孕穗期、抽穗开花期耗水量与水稻经济系数呈显著负相关。研究结果可为寒地黑土区水稻合理制定灌溉制度提供理论依据。

Abstract:In order to explore the response of rice dry matter accumulation to the water consumption process in the cold black soil region, the rice water consumption test was performed by evapotranspiration in the rice irrigation test station in Heilongjiang Province in 2017. The U7(76) uniform test was conducted to analyze the influence of water consumption in each growth stage on rice dry matter quality and dry matter accumulation process deeply. The results showed that the order (from large to small) of the determinant coefficient of water consumption in each stage on rice dry matter quality was bloom, coupling effect of jointing and booting with bloom, jointing and booting, coupling effect of bloom with milk ripe, coupling effect of filled tillering with bloom, coupling effect of filled tillering with jointing and booting, and filled tillering. During the rice vegetative growth stages, through the time the dry matter accumulation entered into the rapid growth stage and the maximum of growth rate, the water consumption affected the dry matter accumulation quality indirectly. Each additional millimeter of water consumption in filled tillering would shorten the time the dry matter accumulation entered into the rapid growth stage by 0.459d;while each additional millimeter of water consumption in jointing and booting would speed up the dry matter accumulation in 0.0113g/d. During the reproductive growth stages, the direct effect of water consumption on the dry matter quality was greater than that of indirect effect. The effects of water consumption in each stage on rice yield and dry matter quality were the same, and the order from large to small was bloom, jointing and booting, filled tillering, milk ripe, early tillering, and late tillering, while the water consumptions in jointing and booting stage and in bloom stage were negatively correlated with the economic coefficient. The result could provide theoretical basis for making the irrigation system in cold black soil region.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
