近几年来,各地水稻科研工作者和农民育种家,都在通过不同途径探索水稻高产育种问题,以期在继高杆变矮杆后,在水稻生产再来一个大的突破,跟上国民经济新跃进的步伐。例如,有人提出丛生快长或早熟高产类型,进一步争取更多穗数或提高每日生产量来夺取高产;有人主张穗数、粒数并重;有人致力于“上攻粒重、下攻根”;有人从事高光效品种的选育等等。一些地区和单位已取得可喜成绩,为我们再闯高产开阔了眼界,增强了信心。由于各地气候条件和生产水平不同,影响产量提高的主要矛盾不一样,水 In recent years, all over the rice research workers and farmers breeders are exploring the issue of high-yielding rice breeding through different channels, with a view to continue to make a big breakthrough in rice production, follow the new national economic leap forward pace of. Some people, for example, have proposed that there should be clusters of fast-growing or early-maturing high-yielding types, and further strive for more spikes or higher daily yields to win high yields. Some have argued that the number of spikes is equal to the number of grains; ; Some people engaged in high light efficiency breeding and so on. In some areas and units, gratifying achievements have been made, broadening horizons for us to break through high-yielding products and boosting our confidence. Due to the different climatic conditions and production levels, the main contradictions affecting the output increase are not the same. Water
