This experiment was conducted to improve the germination when we sowed Chinese milk vetch (Astragalus sinicus L. Local vas. Jinjoo) in the up-land.. The results are summerized as follows 1. There is no difference on the germination of Chinese milk vetch from $15^{\circ}C$ to $35^{\circ}C$. Germination ratio is 7l%, speed is 60% and mean of germinating day. is about 4. But at $10^{\circ}C$ germination ratio and speed are decreased as 65%, 8% but mean of germinating day is increased as 8. 2. Chemicals used for improve of germination $KNO_3$, $H_2SO_4$, HCl, NaOCl, NaOH and GA were increased about 6~8% of germination ratio. 3. Germination in response to soil covering up depth, surface sowing showed 68% of germination and not more than 4cm the seed is germinated 60% but not less than 6cm, germination ratio is not more than 50%. 4. Soil water content needed in the germination is proper about 70~80% of field water capacity and the ratio is 65% but not. more than 40% germination ratio is not more than 31%. 5. Germination in response to seed treatment (1 day sbsorption /1 day dry) germination ratio is not decreased when it treated 2 times but not less than 3 times it decreased seriously and not less that: 5 times it decreased not more than 31%. 6. Germination in response to seed largement, small seed is not good for germination, so seeds harvested after the majority of the seed is ripened.
