At this time, a seedbed can be built. The seedbed can be 10 cm high and 100~ 120 cm wide, and it should be shaped like a turtle's back. It is best to choose seeds with medium maturity. After selecting the seeds, you can soak them in warm water all day. After the seeds are fished out, the water drops should be dried, then mixed with plant ash or fine sand, and the seeds can be sown. When sowing, we should build some sheds and strengthen management. Fertilize and weed regularly, and keep the seedbed moist.
Planting Alisma orientalis should also pay attention to seedling management, especially when the temperature is very high, to avoid soil drought and heat dissipation. Pay attention to the amount of water when watering, so as to ensure the better growth of seedlings. Moreover, if it is rainy, drainage should be carried out in time to prevent the seedlings from rotting due to accumulated water. In the future, topdressing should be carried out according to the growth of seedlings to provide the necessary nutrition for seedlings.
Because the seedling stage usually takes about a month, and then it will be transplanted, it is best to choose cloudy days or evening when transplanting, because the chances of success will be higher. Moreover, the appropriate density should be selected when transplanting, which can better improve the yield and quality. It should be noted that the density between vaccines should be reasonable, and generally about 9000 plants can be planted per mu. Appropriate planting density should be selected according to the base area and seedling size.
