在毛主席革命路线指引下,我国杂交水稻,在短短几年内培育成功,并迅速应用于生产,为大幅度地提高我国水稻产量开辟了新的途径。华主席和党中央亲切关怀、热情扶植这一新生事物,使杂交水稻的科研和生产不断发展和提高,大大地丰富了我国育种科学的理论和实践,并对我国农业科学研究工作产生深远的影响。1976年我们在已有的基础上,根据全省杂交水稻科研协作计划,选择了南优2号及其亲本三系,在几个主要生育时期,作了一些有关光合效率、呼吸机能、根系活力等方面的对比分析测定。希望通过分析测定,逐步了解亲本三系对杂种生理机能以及产生优势的影响,同时希望逐步弄清杂种及其亲本三系有关物质代谢和生理机能的变化趋势,并找出一定的指标,供栽
Under the guidance of Chairman Mao’s revolutionary line, hybrid rice in China has been successfully cultivated in just a few years and rapidly applied to production, opening up new avenues for drastically increasing the output of rice in our country. Chairman Hua and the CPC Central Committee cordially care and warmly support this new birth thing so that the research and production of hybrid rice will continue to develop and increase. This greatly enriches the theory and practice of breeding science in our country and will have a profound impact on our country’s agricultural science research work . In 1976, on the basis of the existing plan, we selected Nanyou 2 and its parents for three lines according to the provincial plan of hybrid rice scientific research. During several main growth periods, we made some suggestions on photosynthetic efficiency, respiratory function, root activity And other aspects of comparative analysis determination. Hope that through the analysis and determination, and gradually understand the parents of three lines on the physiological function of hybrids and the advantages of production, and hope to gradually understand the hybrids and their parents three lines of related substances metabolism and physiological function trends, and find some indicators for the planted
