我们队,过去没有种过杂交玉米,一九七七年春建立玉米科研组,试种杂交玉米高产田一亩五分,品种群单105,早造总产干粒1857.8斤,平均亩产1238.5斤,间种黄豆亩产15.5斤;晚造收玉米干粒1128斤,平均亩产752斤。早晚两造合计亩产玉米1990.5斤,加上黄豆,首创我队畲地亩产一吨粮的记录。高产试验田的主要栽培措施是: 1.深耕,足肥改土,双行密植,打好丰产基础在播种前,我们把犁翻晒好的畲地,每隔3.8尺开一条宽1.5尺,深一尺的播
Our team, in the past have not been planted with hybrid corn, the establishment of corn research group in the spring of 1977, test hybrid corn high yield field acre five points, 105 species groups, as early as 1857.8 kg of total dry grain production, the average yield of 1238.5 kg , Inter-species soybean 15.5 kg per mu; evening harvested 1128 kg dry corn, the average yield 752 kg. In the morning and evening, a total of 190.5 kilograms of corn per mu was produced. Together with the soybeans, a record of producing one ton of grain per mu for our team was conducted. The main cultivation measures of high-yielding experimental field are: 1. Deep plowing, enough fertilizer to soil, double row close planting, laying a good foundation for yielding Before sowing, we plow the sun drying well, every 3.8 feet open a wide 1.5 feet deep one Sowing
