我们公社有87,000亩耕地,地势较平坦,适于机械化栽培。近两年来机械作业的实践表明,无论是高粱还是玉米,采取大垄形式,都较为有利。景家堡四队今年有140多亩丹玉6号玉米,采取1.8尺大垄,株距1尺,平播后起垄,四铲三趟,每亩实收3,000株左右,平均亩产达1,000斤。育新十队玉米1.8尺大垄,株距1～1.2尺,平均亩产900多斤。育新十队还搞了“晋杂1号”高粱1.5尺原垄、1.8尺大垄、2.2尺大垄双行三种不同形式的大面积(各40亩)对比试验,结果大垄栽培表现较好,大垄单行与大垄双行分别比原垄高粱增产6.8%和26.7%。 Our commune has 87,000 mu of arable land, which is relatively flat and suitable for mechanized cultivation. The practice of mechanical work in the past two years shows that it is more advantageous to adopt the form of a large ridge, whether it is sorghum or corn. Jinguang four teams this year, 140 acres of Dan Yu No. 6 corn, to 1.8 feet wide ridge, spacing 1 foot, flat sowing ridge, four shovel three times, about 3,000 acres of real harvest, the average yield of 1,000 jin. New ten sets of corn 1.8-foot wide ridge, spacing 1 ~ 1.2 feet, the average yield of 900 kilos. Yuk new ten team also engage in “Jin hybrid 1” sorghum 1.5 feet ridge, 1.8 feet wide ridge, 2.2 feet wide ridge double row three different forms of large area (40 acres) comparative test, the results of large ridge cultivation performance Better, big ridge single row and big ridge double row than the original ridge sorghum yield 6.8% and 26.7%.
