The invention relates to a bionic cultivation method for precious oil source plant microula sikkimensis grown specifically in the Tibet plateau and rich in Gamma-linolenic acid, and the method includes selecting varieties with low fruitdrop rate for use; breeding fine varieties and supplying variety sources in irrigated areas with the altitude between 2000 to 2300m; establishing a bionic cultivation base in appropriate dry farming fields, grassland from farmland or deteriorated grassland with the altitude between 2200 to 4200m in the original production area of microula sikkimensis. EMS solution with the concentration of 0.1 to 0.2 percent is used for dipping seeds before spring sowing, and then the seeds are mixed with sand and treated under the low temperature of 3 to 5 DEG C for 3 to 5days, thus the germination capacity of the seeds can be improved by more than 70 percent. The interplanting of the seeds and root tuber is carried out, the treated seeds are sowed in drill first, thesowing amount is 400 to 500g per mou; the sowing is conducted between the last third of August and the first third of September in autumn, with the sowing amount of 600 to 700g per mou, the row spacing of 40cm, the root distance of 10cm and the cultivation amount of the root tuber of 17,000 strips per mou. By utilizing the fruitdrop characteristic of the microula sikkimensis, after sowing once, the summer harvest for a batch of seeds and the fall harvest for a batch of root tuber can be realized each year and can continue for 3 to 5 years. The bionic cultivation method of the invention successfully solves the technical problem that seeds are not easy to harvest in large-scale cultivation of the microula sikkimensis and provides scientific and advanced practical technique for the sustainable utilization and large-scale cultivation of the microula sikkimensis resource.
