一九七四年全队种植的四十五亩玉米,平均单产一千二百九十五斤,一九七五年全队种植的玉米也在千斤以上,我们的具体作法是“四早促一早”,即: 一、早播种。从前,因壮原地区气候凉,玉米成熟不好,近几年为使玉米早生根、早发苗,我们提早从三月二十日开始播种,月底种完,四月下旬出苗,比以往早种十天到半月。品种采用英粒子,头年先在田间单株选择早熟、穗大的玉米棒子,挂晒越冬,到来年去两头留中间籽粒作种用。每亩施农家肥三十车,磷肥一百五十斤。实行等行距种植,即隔两杠种一杠,行距一尺六寸,株距八、九寸。每亩保苗四千株左右。

In 1974, the average output of 45 mu of corn planted by the team was 1,295 kilograms. In 1975, more than one kilogram of corn was planted by the entire team. Our specific practice is “ Early morning ”, namely: First, early sowing. Once upon a time, due to the cool climate in Zhuangyuan and the poor maturity of maize, in order to make early roots and early seedling of corn in recent years, we planted it early from March 20, the end of the month and the end of April germinated earlier than usual Ten days to half a month. British species of varieties of particles, the first year in the field first single plant selection precocious, spike large corn cob, hanging the sun over the winter, the next two years to stay in the middle of the seeds for planting. Farmers apply fertilizer per acre thirty cars, 150 pounds of phosphorus fertilizer. The implementation of line spacing planting, that is separated by two bar a bar, spacing of one foot six inches, spacing of eight, nine inches. Seedlings per mu four thousand or so.
