What are the precautions for planting Zedoary?
Zedoary is a Chinese medicinal herb, also known as Shuyo or turmeric, and is a perennial herbaceous plant of the genus Curcuma. Its rhizome can be used as medicine and has the effects of promoting qi and relieving pain, dispersing accumulations and nodules, and breaking blood and removing stasis, with good effects on the human liver and gastrointestinal tract. Many people want to grow it, so below the editor brings you the precautions for planting it.
1. Growing environment
Zedoary has relatively strict requirements for the ecological environment. It prefers a warm and humid climate and is suitable for planting in loam or sandy loam with deep soil layers, good drainage, a loose and fertile upper layer, and a compact lower layer. Low-lying areas prone to water accumulation are not suitable for planting. The soil requires a loose upper layer and a compact lower layer, which can prevent the tubers from entering the soil too deeply and causing incomplete excavation. In addition, vegetable garden soil is fertile and loose and suitable for its growth, and secondly wheat fields can also be used for planting. Before planting, the land must be prepared and fertilized. After fully mixing the soil and fertilizer, shape and rake it level, and make beds.
2. Planting time and method
The planting time of Zedoary is closely related to its variety and the local climate and environment. Under normal circumstances, the planting time for Zedoary is from May to June, but in regions near the tropics the temperature is higher, and by May to June the temperature is already very high, so planting at this time is no longer favorable for its growth. Therefore, in regions near the tropics, such as Guangxi and other places, it is generally planted in February. In addition, Zedoary is propagated by rhizomes, so in winter high-quality seed rhizomes must be selected and treated with plant ash, which can increase the emergence rate.
3. Seedling stage management
After emergence, loosen the soil and remove weeds in a timely manner. Weeds will affect the growth of the seedlings. When weed infestation is severe, the growth space and nutrients of the seedlings are taken away, which in mild cases causes the seedlings to grow thin and weak, and in severe cases causes them to wither and die. Therefore, throughout the entire growth process, weeds must be removed frequently so that there are no weeds in the field. At the same time, in order to promote seedling growth, after weeding, timely topdressing should be applied, and attention should be paid to watering to keep the soil moist. During the rainy season, attention should be paid to drainage to avoid root rot of the seedlings.
4. Pests and diseases
Zedoary has quite a few pests and diseases during planting. The main diseases include leaf spot and root rot. Generally, the peak period of these diseases is during high temperature and rainy weather, and at this time thiophanate and mancozeb can be sprayed for control. The main insect pests include underground pests such as cutworms and white grubs, which can be controlled by using black light traps to lure and kill them or by poisoning them with trichlorfon.
