In mid-April, when the water temperature rises above 15℃, sow 50 grams of Sophora alopecuroides seeds per mu. Before sowing, add 3 ~ 5 cm of water to the pool, with the deepest depth not exceeding 20 cm. Expose the seeds in sunny days for 1 ~ 2 days, then soak the seeds for 12 hours, take them out and rub them out of the fruit. And clean up the mucus on the seeds, then wrap the seeds with semi-dry and semi-wet fine soil or fine sand and sow them in the whole pool. There are still many seeds in the rubbed fruit that have not been rubbed out and are scattered in the pool. When the water temperature is 18 ~ 22℃, it takes 4 ~ 5 days for seeds to germinate, and the germination rate exceeds 98% at 15 days.
