Latest Guide to Curcuma Planting Precautions
Curcuma is a kind of Chinese medicinal herb, also known as Shuyo and Jianghuang (turmeric), and is a perennial herbaceous plant of the genus Curcuma. Its rhizome can be used as medicine, having the effects of promoting the flow of qi and relieving pain, resolving accumulations and masses, and breaking blood stasis, and it has very good effects on the human liver and stomach and intestines. Many people want to plant it, and below the editor brings you its planting precautions.
1. Growing environment
Curcuma has relatively strict requirements for the ecological environment. It likes 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 land that easily accumulates water is not suitable for planting. The soil is required to be loose in the upper layer and compact in the lower layer, so as to avoid the tubers going too deep into the soil, which would lead to incomplete harvesting. In addition, vegetable garden soil is fertile and loose, suitable for its growth, and secondly wheat fields can also be used for planting. Before planting, the land must be prepared and fertilized, and after the soil and fertilizer are fully mixed, it should be shaped and raked level, and beds made.
2. Planting time and method
The planting time of Curcuma is closely related to its variety and the local climate and environment. In general, the time for planting Curcuma 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, planting is generally done in February. In addition, Curcuma 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, loosening the soil and weeding should be carried out in time. Weeds will affect the growth of the seedlings. When weeds are 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, weeding must be done frequently, so that there are no weeds in the field. At the same time, in order to promote seedling growth, after weeding, topdressing should be applied at the appropriate time, and attention should be paid to watering to keep the soil moist. During the rainy season, attention should be paid to drainage to prevent the seedlings from rotting at the roots.
4. Pests and diseases
Curcuma has relatively many pests and diseases during planting. The main ones include leaf spot disease and root rot, and generally high temperature and rainy conditions are the peak period for these diseases. At this time, Tuzet and mancozeb can be sprayed for control. The main insect pests include underground pests such as cutworms and grubs, which can be controlled by using black light traps to lure and kill them or by poisoning them with trichlorfon.
