“种”是农业“八字宪法”的重要组成部分。在毛主席革命路线指引下,我县推广良种工作取得很大成绩,推动了农业生产的发展,但由于种子提纯复壮工作没有跟上,品种混杂、退化严重,有些良种不良了。一九七二年,我所开始建立“两田三圃”制生产原种。几年来,已生产了原种154,830斤。经过社队试种、繁殖,都获得显著的增产效果,深受广大贫下中农欢迎。我所今年水稻平均亩产比去年增产一成,较未建立“三圃”前的一九七一年增产15％。实践证明,生产原种不仅提高了种子纯度,更重要的是提高了种性,发挥了富有丰产性状株系的增产潜力,使产量大大提高,是一项成本低、收益大的增产措施。 “Species” is an important part of the “eight-character constitution” of agriculture. Under the guidance of Chairman Mao’s revolutionary line, great achievements were made in popularizing improved varieties in our county and promoting the development of agricultural production. However, due to the fact that the work of purifying and rejuvenating seeds has not kept pace, the varieties are mixed, the degeneration is serious and some of the improved varieties are not good. In 1972, I started to establish the original production of “two fields and three gardens”. In the past few years, 154,830 kilograms of original stock have been produced. After the commune trial, breeding, have been significantly increased yield, welcomed by the majority of poor farmers. Our average output of paddy rice this year increased by 10% over last year and 15% more than that of 1971 before the establishment of “three nurseries.” Practice has proved that the production of original species not only increased the purity of the seed, more importantly, increased species, play a yield-rich line of yield potential, greatly increase production, is a low-cost, large yield increase measures.
