The management of Chinese herbal medicine Astragalus membranaceus is also very important in the seedling stage, but the seedling stage is also divided into two cases. The former case is to start managing the seedlings when using the seedlings to breed, and the other is to transplant the seedlings. It is managed.
How is the management of Astragalus seedlings?
one. Seedling management. After sowing, keep the ground moist, which is conducive to the emergence of seedlings. After the seedlings are unearthed, remove the covered weeds and gently move the topsoil to keep the ground loose. The bottom is moist, which is good for the roots to extend downwards. When the seedlings grow to 4cm high, they will be shallow once, and the dense seedlings will be removed. The nursery field is kept at a distance of 6 cm from the Zhu, and the seedlings are only planted at a distance of 12 cm. After the seedlings are planted, the grass will be simmered, the water will be watered during the drought, and the rainy season will be guarded against flooding.
two. Management after transplanting. After the survival, pay attention to the soil and keep the ground clean. Astragalus has strong drought resistance. In case of severe drought or topdressing, it can be properly watered. Generally, it is not necessary to water. After "Lixia", 1000kg per acre of soil and 150kg of grass ash will be added. After mixing, open shallow ditch in the row, and often weeding after covering the soil to keep the ground free of weeds. Generally, from June to September, the seed maturity period is inconsistent, and it falls with the maturity. For example, the harvested seeds should be harvested in time and stored for later use. If you do not need to receive seeds, you can remove the flower buds to facilitate root growth.
The management of these two periods is not negligible, and the specific operations are as described above.
