A Detailed Guide to the Planting Time and Cultivation Techniques of Anemarrhena asphodeloides
AbstractCultivation techniques: It is best to choose well-drained sandy loam or neutral soil rich in humus, plant horizontally and flat in furrows 4-5cm deep at a row spacing of 18-20cm and a plant spacing of 5-7cm, remove weeds promptly when the seedlings grow to 3cm, apply nitrogen fertilizer during the growing period, and apply additional nitrogen and potassium fertilizer later, irrigate once with wintering water before the ground freezes each year, and prevent damping-off, soft rot, and so on. Per-mu income: The per-mu yield is related to the climate of the planting site and the cultivation techniques, and the per-mu income is about 2000-3000 yuan.
Anemarrhena asphodeloides is a Chinese medicinal herb with very high medicinal value. Consumed in appropriate amounts, it has benefits such as relieving cough and reducing phlegm, and moistening the lungs. Therefore, many people now choose to grow Anemarrhena asphodeloides, but most people want a comprehensive understanding of its timing and cultivation techniques before planting. Let us take a look below!
Cultivation Techniques of Anemarrhena asphodeloides
1. Site selection and land preparation: When planting Anemarrhena asphodeloides, the work of site selection must be done well. It is best to choose well-drained sandy loam and neutral soil rich in humus, 1500 kg, deep plow 25-30 cm, harrow fine and level, make beds 1.2 m wide, and also dig drainage ditches well to avoid water accumulation.
2. Timely planting: When planting, be sure to pay attention to the row spacing. Plant horizontally and flat in furrows 4-5 cm deep at a row spacing of 18-20 cm and a plant spacing of 5-7 cm. After planting, cover with soil, press firm, and water. Transplanted seedlings should preferably carry more fibrous roots, which helps survival. When planting, the amount must be controlled well, roughly 100-200 kg per mu.
3. Intertillage and weeding: Anemarrhena asphodeloides does not grow quickly during the seedling stage. When it is about 3 cm tall, pull out weeds and loosen the soil promptly, and keep the soil loose and free of weeds during the growing period, which will be more beneficial to the growth of its seedlings.
4. Reasonable topdressing: During the seedling growth period, it is best to apply nitrogen fertilizer. Apply 1500 kg of human and livestock manure water per mu, or 6 kg of urea, and water once after application. For later topdressing, nitrogen and potassium fertilizers are better, applying 10 kg of urea and 7 kg of potassium chloride per mu, or 20 kg of compound fertilizer. The amount of fertilizer also needs to be controlled well.
5. Drainage and irrigation: Anemarrhena asphodeloides is irrigated once with wintering water before the ground freezes each year, which can prevent drought in winter. After sprouting and emerging in spring, if the soil is dry, water promptly to promote root growth, and after heavy rain, drainage work also needs to be done well.
Planting Time of Anemarrhena asphodeloides
When planting Anemarrhena asphodeloides, a suitable time needs to be chosen. It is done in autumn or early spring, and it is best to sow and raise seedlings in spring, then plant after tiller buds have formed in autumn. Therefore, everyone should grasp the timing well.
Pests and Diseases of Anemarrhena asphodeloides and Their Control
1. Damping-off. Damping-off is one of the common diseases of Anemarrhena asphodeloides. For control, crop rotation needs to be implemented, and plots with good drainage and loose soil should be chosen for planting. Before planting, soak the seed rhizomes for 15 minutes in a 1:500 thiram solution or a 40% formaldehyde solution diluted 50 times with water, apply more phosphorus and potassium fertilizer to enhance disease resistance, spray 1:1:200 Bordeaux mixture once before emergence, and after emergence, spray 50% carbendazim 1000-fold solution 2-3 times to protect the seedlings. After disease occurs, pull out diseased plants promptly, disinfect the diseased area with 50% lime milk, and pay more attention to the ratio when preparing the agents.
2. Soft rot. The incidence of soft rot is also very high. During treatment, choose healthy and disease-free seed bulbs for propagation, pay attention to clearing ditches and draining water during the rainy season to lower the water level, soak the seeds for 20-30 minutes in a 50% carbendazim 500-600-fold solution before sowing, and sow after drying. When harvesting and transporting, try as much as possible not to bruise the rhizomes. Finally, attention also needs to be paid to timely ventilation and cooling management.
Per-Mu Income of Anemarrhena asphodeloides
The per-mu income from growing Anemarrhena asphodeloides is related to the environmental climate of the planting site, cultivation techniques, and so on, and the per-mu income is generally 2000-3000 yuan.
When planting Anemarrhena asphodeloides, the work of site selection must be done well. As for timing, it is best to choose spring and autumn each year. After planting, field management and pest and disease control also need to be strengthened. Only by doing these well can Anemarrhena asphodeloides grow better.
