水气热耦合作用下寒区稻种吸水规律试验研究

Experimental Study on Water Absorption Law of Rice Seeds in Cold Regions under Water Air Thermal Coupling Cooperation

实施水气热耦合供给的新型浸种催芽模式已开始在水稻种植中实践和推广。稻种萌发过程中,水分、氧气和温度的相互作用关系尚未完全摸清。选择增氧时距和温度为控制参数,对绥粳27稻种吸水规律开展全因素试验分析。结果表明,稻种吸水速度主要受温度影响,受氧气状态影响不明显。稻种吸水速度随温度升高而增加,可通过调节温度的方式缩短浸种耗时。

The implementation of a new type of seed soaking and germination inducing model that couples water,air,and heat supply has begun to be practiced and promoted in rice cultivation.The interaction between water,oxygen,and temperature during the germination process of rice seeds has not been fully understood.A full factor experimental analysis was conducted on the water absorption law of Suijing 27 rice seeds by selecting the time interval and temperature as control parameters.The results showed that the water absorption rate of rice seeds was mainly affected by temperature,and was not significantly affected by oxygen status.The water absorption rate of rice seeds increases with the increase of temperature,and the soaking time can be shortened by adjusting the temperature.
