稻稻晚秋薯三熟制是在农业学大寨运动中从薯稻稻三熟制的基础上发展起来的。它的特点是“一早、两改、三优势”,即早造早插,晚稻改为中稻,冬薯改为晚秋薯,在保证早造高产稳产优势的前提下发挥中造及晚秋薯的优势。东山公社1976年试种4130亩,晚秋薯平均亩产2100斤,东溪大队3个基点队试种61.27亩,平均亩产2690斤,第3队高产田4.67亩,平均亩产4547斤,最高1.07亩,亩产4873斤。它的优点在于在保证两造水稻高产优势的基础上,有效地利用从10月到第二年2月这段对番薯有利的气候条件,使全年作物对太阳能源的
Rice cropping of late autumn triple-cropping system was developed on the basis of three-cropping system of potato and rice in the movement of Dazhai in agriculture. It is characterized by “early morning, two changes, three advantages”, that is, the early make early plug, late rice to medium rice, winter potato into late autumn potato, ensuring the advantages of early made high yield stable under the premise of making and late autumn potato advantage . Dongshan commune in 1976 planted 4,130 acres, the average yield of late autumn potato 2100 pounds, Dongxi Brigade 3 base team test 61.27 acres, the average yield 2690 pounds, the third team 4.67 acres of high yield fields, the average yield 4547 pounds, the highest 1.07 mu, 4873 kg per mu. Its advantage is that on the basis of ensuring the high yield of two-rice making, it is effective to utilize the favorable climatic conditions for sweet potato from October to the next February so as to make the full-year crop to solar energy
