在毛主席革命路线指引下,我省蚕区广大干部、贫下中农和蚕桑科技人员,积极开展科学实验,1966年试栽桑树无干密植成功。无干密植可使桑树速生高产,当年栽桑,当年采叶养蚕,当年亩产桑叶超千斤,亩产蚕茧超百斤。栽植后2—5年内,还能大幅度增产,亩产桑叶可稳定在5,000—6,000斤,甚至更高一些。据1972年秋统计,全省已有50多个县试种,栽培面积达6万多亩。 Guided by Chairman Mao’s revolutionary line, a large number of cadres, poor middle peasants and sericulture scientific and technological personnel in our province’s silkworm area actively carried out scientific experiments. In 1966, the test mulberry trees were successfully dried without planting. Drying can make mulberry fast-growing high yield, then planted mulberry, year-old leaf sericulture, mulberry leaves mu per mu when super-mu, per mu cocoon yield per kilogram. 2-5 years after planting, but also a substantial increase in yield, mulberry leaves can be stable at 5,000-6,000 pounds, or even higher. According to the statistics of the autumn of 1972, more than 50 counties in the province have been experimentally cultivated and their cultivation area has reached 60,000 mu.
