滨海地区增温对水稻产量及稻米品质的影响

Effect of Increasing Temperature on Rice Yield and Rice Quality in Coastal Area

为探究滨海地区增温对水稻产量及稻米品质的影响,以“盐粳476”、“盐粳313”为试验材料,设增温(增加2℃)、常温对照两个处理进行试验。结果表明:水稻花粉不育率增温处理盐粳476为15.18%、盐粳313为12.56%;增温处理盐粳476产量为277.81 kg/667 m^(2)、盐粳313产量388.36 kg/667 m^(2),比相对应的CK处理大幅减产,分别减产231.89 kg/667 m^(2)、265.3 kg/667 m^(2);增温处理的加工品质大体呈下降的趋势,增温处理相比于对应CK处理食味值降低、直链淀粉含量和蛋白质含量升高。

In order to investigate the effects of temperature increase on rice yield and quality in coastal areas,two treatments of temperature increase(2℃)and normal temperature control were used as experimental materials,"Yangeng-476"and"Yangeng-313".The results showed that the fertility rate of rice pollen was 15.18%for Yangeng-476 and 12.56%for Yangeng-313.The yield of Yangeng-476 and Yangeng-313 were 277.81 kg/667 m^(2)and 388.36 kg/667 m^(2)respectively,which were significantly reduced by 231.89 kg/667 m^(2)and 265.3 kg/667 m^(2)respectively compared with the corresponding CK treatment.Compared with CK treatment,the food taste value decreased and amylose content and protein content increased.
