Latest Technical Method Tutorial for Field Management of Anemarrhena asphodeloides
Anemarrhena asphodeloides is a perennial herb of the Liliaceae family. Its rhizome can be used as medicine and has the effects of clearing heat and purging fire, relieving cough and eliminating phlegm, and calming the fetus. Current market demand is very large, and it is one of the major medicinal materials in China. With the depletion of wild resources, the trend of artificially cultivating Anemarrhena asphodeloides is growing. Doing a good job in field management during planting is an important measure to achieve yield and returns. Let us take a look at the key points of field management for Anemarrhena asphodeloides.
1. Thinning and final singling of seedlings
Anemarrhena asphodeloides is divided into two types: seed propagation and division propagation. When using seed propagation, thinning should be carried out in time after emergence. When thinning, strong seedlings should be retained, and weak and diseased seedlings should be removed. The remaining seedlings after thinning can be transplanted elsewhere, or if there is dead seedling phenomenon after thinning, replanting should be carried out in time. When the seedlings grow to 10 cm high, final singling can be carried out at this time. The plant spacing for final singling should be controlled at 7-10 cm, and can also be increased or decreased accordingly according to the growth of the seedlings and soil fertility; for general soil fertility, it can be sparser.
2. Loosening soil and earthing up
When the seedlings grow 3 true leaves, the soil should be loosened and weeds removed at this time. When loosening the soil, it should not be too deep, so as not to damage the seedling root system and cause poor growth or death of the seedlings. Weeding should be frequent, removing weeds as soon as they are seen, so as to prevent weeds from seizing growth space and nutrients from the seedlings. In addition, when there are too many weeds, diseases and insect pests are very likely to occur. When the plants grow larger, only 2-3 times of soil loosening and weeding are needed each year thereafter. Because the root system of Anemarrhena asphodeloides is distributed relatively shallowly and mostly grows in the surface soil layer, it will be exposed after rain or watering, so attention should be paid to earthing up to prevent lodging.
3. Topdressing
⟦NL>If you want the plants to grow quickly and have high yield, fertilization is inevitable. For each mu, 4000 kg of decomposed farmyard manure and 20 kg of compound fertilizer should be applied in batches. Stir them evenly and spread them beside the root system, and combine with soil loosening to cover them under the soil. In addition, after topdressing, water 1-2 times so that the fertilizer penetrates downward, which is beneficial to root absorption. In addition, during the peak growth season of Anemarrhena asphodeloides, foliar fertilizer should be sprayed every half month, which can improve the disease resistance of the plants and promote rhizome growth and expansion, increasing yield.
4. Irrigation
After sowing, water frequently to keep the soil moist. During growth, water an appropriate amount according to soil moisture conditions and climate changes. Water in time during drought to prevent the plants from lacking water, while in the rainy season attention should be paid to drainage to prevent root rot. Before overwintering, water well for overwintering to help the plants overwinter safely. After the plants sprout in spring of the following year, water appropriately during drought.
