近年来,四川蚕业生产部门用“蚕叶草”代替桑叶饲养家蚕成功。我区为了解决桑叶紧缺,加快养蚕数量,探索蚕叶草的养蚕价值大小,于1990年从四川引种蚕叶草,分别进行养春蚕3次、秋蚕2次添草养蚕试验,均获得基本相同的结论,现将有关研究试验结果,详述如下:一、试验设计1.供试材料春蚕为武都蚕桑中心从江苏引进的苏5×苏6止反交种,秋蚕是从陕西引进的菁松×皓月蚕种。蚕叶草由四川绵阳市情报研究所提供种子,种在农科所试验地内,1年可采收3～4次,亩产草8300公斤。蚕叶草为菊科、莴苣属1年生草本植物,株高1～2米,叶互生,无叶柄,柔软多汁,叶长条形,边缘不规则分裂,叶长10～50厘米,宽8～ In recent years, Sichuan silkworm production sector with “silkworm grass” instead of mulberry silkworm breeding success. In order to solve the shortage of mulberry leaf, speed up the quantity of rearing silkworm and explore the value of silkworm rearing culture in our area, we introduced silkworm mulberry from Sichuan in 1990, Are basically the same conclusion, the relevant research test results are now described in detail as follows: First, the experimental design 1 for the test material Spring silkworm Wudu sericulture center imported from Jiangsu Su 5 × Su 6 only anti-crossbred autumn silkworm Jinsong imported from Shaanxi × Haoyue silkworm species. Silkworm leaves from Mianyang City, Sichuan Institute of Information to provide seed, planted in the agricultural experiment, 1 year can be harvested 3 to 4 times, 8300 kilograms per mu of grass. Silkworm leaves as Compositae, Lactuca is an annual herb, plant height of 1 to 2 meters, leaves alternate, no petioles, soft and juicy, long leaves, edge irregular split, leaf length 10 to 50 cm, width 8 ~
