Planting technique of Rhizoma Anemarrhenae the planting time of Rhizoma Anemarrhenae

Planting techniques: it is appropriate to select sandy loam with good drainage or neutral soil rich in humus, according to row spacing 18-20cm, plant spacing 5-7cm, trench depth 4-5cm horizontal flat planting, timely removal of weeds when seedlings grow to 3cm, application of nitrogen fertilizer in growing period, topdressing nitrogen and potassium fertilizer in later stage, irrigation of overwintering water once a year before freezing to prevent blight and soft rot. Mu income: the yield per mu is related to the climate of the planting land and planting technology, and the mu income is about 2000-3000 yuan.

Anemarrhena anemarrhena is a kind of traditional Chinese medicine with high medicinal value. Eating it in an appropriate amount has the advantages of relieving cough and resolving phlegm, moistening the lung and so on. So now there are many people who choose to plant Anemarrhena anemarrhena, but most people want to have a comprehensive understanding of its time and planting technology before planting. Let's take a look at it together.

Planting technique of Anemarrhena anemarrhena

1. Land selection and land preparation: when planting, Anemarrhena anemarrhena must do a good job in land selection. Choose well drained sandy loam and humus-rich neutral soil as good 1500 kg, deep ploughing 25-30 cm, rake fine leveling, 1.2m wide border, but also need to dig drainage ditches to avoid stagnant water.

2. Timely planting: when planting, we must pay attention to the line spacing. According to row spacing 18-20 cm, plant spacing 5-7 cm, trench depth 4-5 cm horizontal flat planting, after planting, covering soil, compaction, watering, planting seedlings should bring more fibrous roots, which is beneficial to survival. When planting, the quantity must be grasped, about 100-200 kilograms per mu.

3. Ploughing and weeding: Anemarrhena anemarrhena does not grow fast during the seedling period, pull out weeds and loosen the soil in time when it is about 3 cm high, and keep the soil loose and free of weeds during the growing period, which will be more conducive to the growth of its seedlings.

4. Reasonable topdressing: during the growth of seedlings, it is best to topdressing nitrogen fertilizer. Topdressing 1500 kg of human and animal dung water per mu, or 6 kg of urea, watering once after application, nitrogen and potassium fertilizer is better in the later stage, 10 kg of urea, 7 kg of potassium chloride per mu, or 20 kg of compound fertilizer should also be well controlled.

5. Drainage and irrigation: Anemarrhena anemarrhena irrigates overwintering water once a year before freezing, which can prevent it from drought in winter. After sprouting in spring, if the soil is dry, water in time to promote root growth, and drainage needs to be done after heavy rain.

Planting time of Rhizoma Anemarrhenae

When planting Rhizoma Anemarrhenae, you need to choose the right time to do it. It is better to sow and raise seedlings in autumn or early spring and to plant tiller buds after autumn. Therefore, in the choice of time, we should grasp it.

Diseases and insect pests of Anemarrhena asphodeloides and its control

1. Blight. Blight is one of the common diseases of Anemarrhena asphodeloides. In the aspect of prevention and control, it is necessary to carry out crop rotation, select land with good drainage and loose soil, before planting, soak the seeds with 500% thiram solution or 40% formaldehyde solution with 50 times water for 15 minutes, increase the application of phosphorus and potassium fertilizers, enhance the ability of Hangzhou disease, spray 1azur 200 Bordeaux solution before emergence, spray 1000 times carbendazim 2-3 times after emergence, protect the seedlings, and remove the diseased plants in time after the disease occurs. The ward is disinfected with 50% lime milk, and more attention should be paid to the proportion of the medicament.

2. Soft rot. The incidence of soft rot is also very high, select robust and disease-free bulbs to breed during the rainy season, pay attention to clear ditches, lower water level, soak seeds with 50% carbendazim 500-600 times solution for 20-30 minutes before sowing, soak seeds after drying, harvest and shipping, try not to damage the rhizome as much as possible, and finally need to pay attention to timely ventilation and cooling management.

Income per mu of Anemarrhena asphodeloides

The income per mu of Anemarrhena asphodeloides is related to the environment and climate of the planting land and planting technology, and the general income per mu is 2000-3000 yuan.

When planting Anemarrhena anemarrhena, we must do a good job in site selection. In terms of time, it is best to choose to do it in spring and autumn every year. After planting, we also need to strengthen the field management and the prevention and control of diseases and insect pests. Only by doing these well can we make the Anemarrhena anemarrhena grow better.
