一九七五年以来,上海郊区试种杂交水稻,表现较好,有一定的增产潛力,很受群众的欢迎。杂交水稻是个新事物,技术性也较强,要把杂交水稻种好,就需要摸清它的脾气,了解它的特点。伟大的领袖毛主席教导我们:“事物发展的根本原因,不是在于事物的外部而是在事物的内部,在于事物内部的矛盾性。”杂交水稻是由两个不同遗传类型的品种杂交而成的,这就构成了杂种内部的较大的生物学矛盾,从而表现出较强的生活力。这种较强的生活力现象,我们就称作为杂种优势现象。杂交水稻同一般的水稻品种相此,有共同的地方,也有特殊的地方。我们必须善于分析事物的矛盾,了解和掌握杂交水稻的脾气和特性,通过相适应的栽培措施,最大限度地发挥杂交水稻的优势和增产潛力。
Since 1975, hybrid rice has been tested in the suburbs of Shanghai with good performance and certain yield-increasing potential, which are very popular with the masses. Hybrid rice is a new thing, and its technology is also strong. To grow hybrid rice well, you need to find out its temper and learn about its characteristics. The great leader Chairman Mao taught us: “The root cause of the development of things is not the external things but the internal things and the internal contradictions in things.” Hybrid rice is a hybrid of two varieties of different genetic types , Which constitutes a large biological hybrid within the contradiction, which showed a strong viability. This phenomenon of strong vitality, we call it the phenomenon of heterosis. Hybrid rice with the same type of rice this phase, there are commonplace, there are special places. We must be good at analyzing the contradictions of things, understand and master the temper and characteristics of hybrid rice, and maximize the potential and yield potential of hybrid rice through appropriate cultivation measures.
