After sowing, it is covered with fine sieve mesh, so that no seeds are used. No sand and sand damage can no longer cover the soil, gently suppress after sowing (tap the bed with a shovel), then spray with water to make the seeds go into practice and close to the soil. If there is sandstorm damage or heavy drought, you can cut the shade and block the wind at the bedside.
Tending management points
After sowing, the willows can be emerged if the temperature and humidity are suitable for 2-3 days. After emergence, pay attention to moisture management, keep the bed surface moist, and pay attention to shading. Do not let the seedlings suffer from sunburn. The rest of the management is the same as poplar. There are many river ponds in the willow producing areas, and the seeds often fall along the water and the wetlands with the catkins, and then naturally grow into seedlings. The author once collected the natural planting of Xiaoliu Miao in the floodplain. It eliminates the need for seed collection and seedling management. The seedlings were as high as 1.5-2 meters and the highest was 2.5 meters.
