我所于1978年开始进行矮早三大麦高产栽培试验,连续三年亩产超千斤。1979年1.04亩,亩产1,073.9斤;1980年1.77亩,亩产1,080斤;1981年1.08亩,亩产1,161斤。高产试验田的土质为沙壤土,肥力中等(有机质含量1.32％—1.56％)。前两年采取宽幅条播,麦幅1.5尺,在11.2尺畦面上种6行麦。去年改为窄行条播,在4.1尺畦面上种24行,平均行距6寸。每亩纯氮用量,前两年分别为49.6斤、50.3斤,今年由于地力较高,下降到25.7斤。
In 1978, we started to carry out high-yielding cultivation trials of short morning three barley, exceeding three kilos for three consecutive years. 1.04 mu in 1979, yielding 1,073.9 kilograms per mu; 1980, 1.77 mu, 1,080 kg per mu; 1981 1.08 mu, mu produce 1,161 pounds. The soil quality of the high-yielding experimental field is sandy loam with medium fertility (organic matter content 1.32% -1.56%). The first two years to take broad-band broadcast, 1.5-meter-wide maize, 11.2-inch mash-planted row of 6 wheat. Last year changed to narrow-strip broadcast in the 4.1-inch surface of a planted 24 lines, with an average spacing of 6 inches. The amount of pure nitrogen per mu, the previous two years were 49.6 pounds, 50.3 pounds, due to higher ground force this year, down to 25.7 pounds.
