我县于1968年示范推广陕棉四号抗病品种.根据毛主席“要认真总结经验”的教导,为充分发挥良种的作用,现就该品种的试验推广过程,品种特性及主要栽培特点作一简结.高陵县位于泾惠灌区中下游,地势平坦,土质肥沃,渠井双灌化,地下水位较高,历史上棉花面积约占50%左右.解放以后棉花产量逐年增加,1959年全县平均亩产37斤.近年来,由于棉花枯、黄萎病的蔓延扩大等原因,使产量下降,面积压缩.1972年面积只占集体耕地的35%.1956年前后,棉花枯、黄萎病在个别田块发生,1960年普遍发生.据资料
In 1968, our county demonstrated and popularized the resistant varieties of Shaan Mian No. 4. According to the teaching of Chairman Mao “should conscientiously sum up experiences ”, in order to give full play to the role of elite varieties, Gaoling County is located in the middle and lower reaches of Jinghui irrigation area, flat, fertile soil, irrigation wells double irrigation, higher groundwater levels, the history of cotton area accounts for about 50% .After liberation cotton production increased year by year, 1959 The county average yield 37 kg in recent years, due to the spread of cotton withered, Verticillium wilt and other reasons, so that production decline, area compression .1972 area accounted for only 35% of collective land .1956 years ago, cotton withered, Verticillium wilt occurred in individual fields and occurred generally in 1960. According to the data
