为了深入研究谷子丰产栽培技术,1975年在陕北教学基地(安塞县砖窑湾)同农作专业、延安农校师生对春、夏谷生育特点进行了初步观察,现简结如下: 一、品种和种植情况春谷观察长农1号、延谷1号,都属丰产田;夏谷观察竹叶青和辽东黄,是品种密度试验的中等密度处理。川水地,黄绵土,土质沙壤,肥力中上。春谷播前亩施土粪万斤,5月13～14日播种,26日出苗。长农1号8～9叶定苗,行距0.9～1尺,亩20,396株。拔节和生长锥伸长刚开始,亩追尿素13斤。定苗和追肥后各中耕1次。8月19～24日浇1水。长农1号因地积水,浇后又下雨吹
In order to further study millet high yielding cultivation techniques, in 1975, teaching base in northern Shaanxi (Ansai County brick kiln) with farming professionals, Yan’an farmers and students of spring and summer cereal characteristics of a preliminary observation of fertility, are summarized as follows: a Varieties and planting situation Spring Valley observation Changnong 1 and Yanu 1 were all high-yielding fields. In summer valley, the observation of bamboo yellows and Liaodong yellow was the medium-density treatment of variety density test. Chuan water, loessial soil, sandy soil, fertility in the upper. Mushu before spring planting soil Million pounds, sowing May 13 to 14, on the 26th seedlings. Changnong 1 8 ~ 9 Ye Dingmiao, spacing 0.9 ~ 1 feet, 20,396 acres of mu. Jointing and growth cone elongation just started, Mu chase urea 13 pounds. Dingmiao and top dressing after cultivating 1 times. August 19 to 24 poured 1 water. Changnong 1 due to the groundwater, pouring rain again
