从1979年以来,我们在研究杂交稻在本省山区适应性的试验中,发现粳型杂交稻比籼型杂交稻有更好的适应山区气候的能力。它具有生育期短、耐低温、抗逆性(风、病)强,比常规稻稳产高产等特点。因此,认为在本省中高山区推广粳型杂交稻具有一定的经济价值。本文以粳型杂交稻黎明×C_5,为代表品种,根据1979——1981年在天目山区田间试验和调查结果,从农业气象角度分析了该品系在山区种植中有关农业气象指标、经济性状及其适宜种植高度等问题,为推广引种提供依据。
Since 1979, when we studied the adaptability of hybrid rice in mountainous areas in our province, we found that japonica hybrid rice has better ability to adapt to mountain climate than indica hybrid rice. It has a short growth period, low temperature resistance, resistance (wind, disease) strong, stable and high yield than conventional rice and other characteristics. Therefore, it is considered that it is of economic value to promote japonica hybrid rice in the middle and high mountain areas of this province. Based on the field experiments and surveys in Tianmushan Mountain in 1979-1981, this paper analyzed the effects of agro-meteorological indicators and economic traits of the line on the cultivation of mountainous areas from the perspective of agrometeorology Suitable for planting height and other issues, provide the basis for the promotion of introduction.
