杂交稻组合选择是再生稻高产栽培的关键,我们对目前赣北大面积生产应用的一晚、二晚及早稻组合进行多年多点试验研究和大面积生产验证表明:协优63具有生育期适宜,适应性广,两季高产;协(汕)46生育期较短,再生稻产量高,但对温度反应敏感,可在温度条件好的地区试种;协优49等早杂组合在种双季晚稻水源条件不够的田块作应变的再生稻组合较为适宜。
Hybrid rice combination selection is the key to high-yielding ratoon rice cultivation. We have conducted many years of multi-year trial and large-scale production verification of the present night, second and early rice combinations in large-scale production and application in northern Jiangxi Province. The results show that: Adaptability, high yield in two seasons; Association (Shantou) 46 shorter growth period, high yield of ratooning rice, but sensitive to temperature, can be good test conditions in the region; Late rice water conditions are not enough for the field of rejuvenation of the rice combination is more appropriate.
