Detailed Explanation of Key Management Techniques for Angelica sinensis During the Overwintering Period
For directly sown Angelica sinensis (Chinese angelica), in combination with topdressing before winter, cover the seedlings with manure-enriched soil or add a layer of fine soil about 1 cm thick over the seedlings to protect them from frost damage; for seedling-raised and transplanted Angelica sinensis, seedling storage work must be done well in winter; for seed-bearing Angelica sinensis, in order to improve seed yield and quality, before harvest, robust and uniform seedlings grown on high mountains or mid-mountain slopes must be selected for seed production. Afterwards, cut off the aboveground parts of the seed-bearing plants, remove all weeds, let them overwinter naturally, and keep watch frequently to prevent livestock from entering and trampling them, which would cause gaps in the seedlings. In early spring of the following year, if weeds are seen growing, they can be pulled out by hand; at this time, the root system covers the soil surface, so hoeing for weed control and fertilization must not be used, to avoid cutting the root system and hindering plant growth.

Key Technical Points for Pest and Disease Control During the Cultivation Period of Gastrodia elata
Gastrodia elata is a commonly used traditional Chinese medicinal herb. It is a special seed plant with no roots and no green leaves; it cannot nourish itself and must rely on symbiosis with Armillaria mellea to obtain nutrients for reproduction and growth. Therefore, cultivating Gastrodia elata differs from growing green plants, and three key steps must be managed according to its growth patterns. First, the cultivation of Armillaria mellea-infected wood; second, the selection and cultivation of Gastrodia elata seed tubers; third, the symbiotic cultivation of Gastrodia elata with Armillaria mellea. In all three production steps there is a chance of contamination by miscellaneous fungi, and if any step is done poorly, especially under unfavorable conditions, it will lead to failure in Gastrodia elata cultivation.

What are the key technical points for managing Schisandra chinensis during its growing period?
1. Water management: In the first year after planting, water should be applied multiple times to ensure soil moisture content, thereby ensuring the survival rate of the seedlings and the normal growth of young trees. For trees that have entered the fruiting stage, in a normal year, ensure 4-5 waterings: pre-flowering water, post-flowering water, fruit-swelling water, and freeze-up water, while combining with intertillage and weeding. After watering, loosen the soil immediately to preserve moisture and prevent soil compaction. 2. Fertilization management: In the first year after planting, in early to mid-June, apply 15-20 kg of urea per 667 sq m as a top dressing. For 2-year-old plants, in early May, apply phosphorus

How do you manage the growing period when cultivating Rehmannia (Chinese foxglove)?
How do you manage the growing period of Rehmannia? Please give a detailed description of the methods. For managing the growing period of Rehmannia, you can refer to the following methods: 1. Weeding in the Rehmannia field: After Rehmannia enters the growing period, its root system develops rapidly, so cultivation should be strengthened to promote deep rooting, keep the soil loose, control excessive vegetative growth of the plants, and prevent weeds from growing densely...
