将垦稻12、绥粳4号混合种植既保留了垦稻12米质优、分蘖力强及绥粳4号有香味的优良特性，又克服了垦稻12秸秆软、绥粳4号分蘖力差的缺点。本文研究了垦稻12、绥粳4号不同比例混播对水稻产量和品质的影响。结果表明，垦稻12和绥粳4号按4∶6的比例混种，提高了水稻抗倒伏能力，增加了水稻茎蘖数，产量达9 233.55 kg/hm2，食味评分87分。

Mixed planting of the two cultivars between Kendao 12 and Suigeng 4, retained the excellent qualities of the strong tillering of Kendao12 and the flavor of Suigeng 4, and overcame the disadvantages on soft straw of Kendao 12 and poor tillering ability of Suijing 4. This paper studied the effects of different mixed planging ratio between Kendao 12 and Suigeng 4 on rice yield and quality. The results showed that mixed planting ratio of 4∶6 between the two varieties could improve the lodging resistence, increase the tiller number, the yield reached 9 233.55 kg/hm2, and the taste reached 87 points.
