在毛主席的无产阶级革命路线指引下,我省蚕区的广大贫下中农、革命科技人员和革命干部,积极地开展了在桑蚕应用保幼激素的科学实验,为我省养蚕事业的发展作出了新的贡献。根据近几年来的试用和推广的结果,桑蚕使用保幼激素后,一般可增加产丝量10—15%。由于使用保幼激素,使桑蚕的5龄期延长了1天左右,用桑量相应增多了10%左右。因此,提高单位土地面积的桑叶产量,是推动保幼激素的扩大使用,促进蚕、桑生产发展的一项迫切任务。
Guided by Chairman Mao’s proletarian revolutionary line, the vast majority of poor peasants and middle peasants, revolutionary scientists and technicians and revolutionary cadres in our province’s silkworm area have actively carried out scientific experiments in the application of juvenile hormones to silkworms, and have contributed to the development of sericulture in our province Made new contributions. According to the trial and promotion results in recent years, silkworms use juvenile hormone, the general increase in silk yield 10-15%. Due to the use of juvenile hormone, so that the 5th instar silkworms extended by about 1 day, with the amount of mulberry increased by about 10%. Therefore, raising the yield of mulberry leaves per unit of land area is an urgent task to promote the expanded use of juvenile hormone and promote the development of silkworm and mulberry production.
