开原县柴河公社柴河大队认真落实农业“八字宪法”,经多年试验,推广了“凤双6428”玉米对垵双株密植的栽培方式。在相应增施肥料的情况下,逐年缩小垵距,增加每亩株数,单产随着相应提高。1969年行垵距1.8×3.0尺,垵内株距1尺,亩产681斤;1970年行垵距1.8×2.0尺,垵内株距7寸,亩产1,021斤;1971年行垵距1.8×1.9尺,垵内株距缩小为5寸,亩产1,222斤。去年,这个大队种植“凤双6428”玉米1,112亩,有490亩采用了行垵距1.8×1.8～2.0尺,垵内株距5～8寸对垵双株密植,比一般清种增产10～15%。
Kaiyuan County Chaihe Commune Chaihe Brigade conscientiously implement the agricultural “Character Constitution”, after many years of testing, to promote the “Feng Shuang 6428” double-sowing Shuangbian corn cultivation methods. In the case of the corresponding increase in fertilizer, narrowing the distance every year, increasing the number of trees per acre, with a corresponding increase in yield. In 1969, the plantation distance was 1.8 × 3.0 feet, and the plant spacing was 1 foot and the yield was 681 kg per mu. In 1970, the plantation distance was 1.8 × 2.0 feet and the plant distance was 7 inches. The yield was 1,021 kg per mu. In 1971, the plantation distance was 1.8 × 1.9 Ruler, 垵 narrowed within the plant spacing of 5 inches, 1,222 pounds per mu. Last year, this brigade planted 1,112 mu of “Feng Shuang 6428” corn, with 490 mu of line spacing ranging from 1.8 × 1.8 to 2.0 feet. The plant spacing within the plant ranged from 5 to 8 inches, and its yield was 10-15 %.
