Please introduce the methods of Rehmannia glutinosa seedling stage management can refer to the following methods: 1.

How to manage rehmannia seedlings? What should I pay attention to? Please give me an introduction The following methods can be used for seedling management of rehmannia root: 1. Weeding in cultivation: from the end of April to the beginning of May, the management should focus on weeding in cultivation. During this period of rehmannia emergence, weeds in the field must be removed in time to prevent weeds from competing for light and fertilizer, affecting the normal growth of rehmannia. At this time, the seedlings are small and the roots are shallow. Be careful not to loosen the rhizomes to prevent damage to the rhizomes. 2. Thinning and seedling determination of rehmannia root: When the seedlings are 3-4 cm high, when the seedlings grow 2-3 leaves, they should be thinned in time. Because rhizomes have more than 2 bud eyes, they can grow multiple seedlings. If they are not thinned in time, they will affect the development of rhizomes in the later stage due to lack of concentration of nutrients. Leave 1-2 seedlings in each hole. Such as found when the lack of seedlings can be supplemented, supplemented seedlings should be watered in time, conducive to seedling survival. 3. Fertilization and irrigation of rehmannia: rehmannia is a densely planted crop, so fertilization must keep up to meet the nutritional needs of plants. Not only enough basal fertilizer should be applied, but also appropriate topdressing. After the seedlings are fully grown, the compound fertilizer should be applied beside the plants (or 100kg of calcium superphosphate and 30kg of decomposed cake fertilizer should be applied per mu after thinning to promote the development and expansion of rhizomes. When sealing the rows, ash should be applied once between rows) to ensure the nutrients required for the growth of rehmannia root and strengthen the medicinal properties of roots. After topdressing, water should be watered in time to meet the needs of rehmannia growth for water, so that plants can fully absorb nutrients.
