在毛主席“以粮为纲,全面发展”的方针指引下,在批林批孔运动的推动下,我省的农业生产和全国生产一样迅猛发展。我省的柑桔生产正处在大发展的前夕,各地纷纷要求良种苗木。因此,加速柑桔良种繁育已成为当前的迫切问题。自1972年开始,我们恢复柑桔选种这项研究工作。两年多来,初步选出三十余个优良单株,并繁殖推广。但是,我省当前柑桔发展的速度远远超过良种繁育的速度,不少地区每年繁殖的柑桔苗木以数百万株计算。因此,如何快速繁育良种接穗,让良种接穗遍布全省,这
Guided by the principle of “taking grain as the key link and all-round development” of Chairman Mao, agricultural production in our province has enjoyed the same rapid development as the national production under the impetus of the “campaign to criticize Lin and criticize the Confucius.” The production of citrus in our province is on the eve of the great development, all over the country require improved seedlings. Therefore, accelerating the breeding of citrus seeds has become an urgent problem. Since 1972, we have resumed the research on citrus seed selection. Over the past two years, the initial selection of more than thirty excellent single plant, and breeding promotion. However, the development speed of citrus in our province far exceeds the rate of thoroughbred breeding. In many areas, millions of citrus seedlings are bred each year. Therefore, how to quickly breeding elite scion, so that varieties of scion throughout the province, this
