伟大的领袖和导师毛主席有1955年就预言:“将来会出现从来没有被人们设想过的种种事,几倍、十几倍以至几十倍於现在的农作物的高产量”。(《毛泽东选集》第五卷252页)现代农学研究突飞猛进,不断地揭示各种作物的高产潜力和高产途径,推动着现代农业生产的高速发展。近十多年来,国内外有许多学者对作物的高产潜力的理论推算进行了广泛地研究。以水稻为例:汤佩松(1963年)根据京津地区单季稻生长季节太阳总辐射量推算京津地区水稻最高亩产干谷为2500斤;竺可桢(1964)以我国长江中下游和华南广大稻区太阳年辐射量推算单季稻每亩可产干谷2823斤。叶诸沛(1963)则从土壤肥力角度出发推算单季稻亩产干谷可达2494斤。薛德榕(1977)根据广州地区太
The great leader and teacher Chairman Mao predicted in 1955: “There will be various kinds of things that have never been envisioned in the future, several times, ten times or even a few times as high as the current crops.” (Selected Works of Mao Zedong, Vol. 5, p. 252) Modern agronomical research advances by leaps and bounds and constantly reveals the high yield potential and high-yielding ways of various crops and promotes the rapid development of modern agricultural production. In the recent ten years, many scholars at home and abroad have conducted extensive research on the theoretical estimation of the high yield potential of crops. Taking rice as an example: According to the total solar radiation of the single season rice growing season in Beijing and Tianjin, Tang Peisong (1963) estimated that the highest dry weight of rice in Beijing and Tianjin is 2,500 kg; Zhu Kezhen (1964) took the sun in the middle and lower reaches of the Yangtze River and in southern China Estimated annual emissions of single-season rice can produce dry valley 2823 kg. Ye Zhu Pei (1963) from the point of view of soil fertility projections single crop of dry acres per mu up to 2494 kg. Xue Derong (1977) according to the Guangzhou area too
