宁县和盛良种场地处黄土高原的董志塬南部,海拔1300米,年平均降水575毫米,年平均气温8.7℃,一月平均气温-5.9℃,绝对最低气温-25.4℃。全场耕地294亩,土壤多属黑垆土,微碱性。繁殖冬小麦良种是该场主要生产任务。建场初,由于土地瘠薄,耕作粗放,品种严重老化混杂,小麦亩产仅80多斤;60年代平均亩产173斤,1969年亩产250.6斤为最高;70年代初平均亩产也只有217斤。1975年以来,通过引进、繁育良种,广辟肥源,培
Ningxian He Shengliang is located in the south of Dongzhi plateau in the Loess Plateau. It has an elevation of 1,300 meters and an average annual rainfall of 575 millimeters with an annual average temperature of 8.7 degrees centigrade. The average January temperature is -5.9 degrees centigrade and the absolute minimum temperature is -25.4 degrees centigrade. The audience of 294 acres of arable land, mostly black soil soil, slightly alkaline. The breeding of winter wheat seeds is the main production task of the field. At the beginning of the establishment of the site, due to the infertile land and extensive cultivation, the variety of serious aging mixed only 80 kilos of wheat per mu; the average yield per mu in the 1960s was 173 kilograms; the highest was 250.6 kg per mu in 1969; and the average yield per mu in the early 1970s was only 217 jin. Since 1975, through the introduction, breeding varieties, widen the source of fertility and training
