Aristolochia, also known as Elaeagnus Elaeagnus and Ophiopogon japonicus, is a kind of medicinal material used for clearing lung-heat, relieving cough, clearing intestine and eliminating hemorrhoids. It has the effects of regulating qi, eliminating dampness, promoting blood circulation, relieving pain, lowering blood pressure and resisting inflammation, but it should be used with caution for those with deficiency of cold and spleen. Even the plants listed as carcinogens by the International Health Organization are controversial about the cultivation of Aristolochia. Today, we will mainly learn about the planting techniques of Aristolochia. Let's take a look at the following explanation.

1, land selection and soil preparation

Aristolochia is light-proof, shade-resistant, cold-resistant and adaptable. Aristolochia should be planted in sandy yellow soil with sufficient soil fertility, good permeability, good drainage, sufficient water and rich humus content. Dig the soil at least 30 cm deep, and then cultivate the land with base fertilizer, which is mainly soil mixed fertilizer or compost with compound fertilizer. Before sowing, turn over the land, make it flat and thin, and make furrows for furrows. The border is about one meter wide, and the borders blend with each other to facilitate drainage and drainage.

2, timely planting

Bone-seeking wind is generally planted in spring when the temperature rises, preferably in March and April, with the highest emergence rate. But if you want to transplant Aristolochia, you need to do it before freezing in winter. When planting, it needs to be planted according to the row spacing of 35 to 40 cm and the plant spacing of 25 to 30 cm. That is, after planting, water it in spring and water it thoroughly. During the seedling period of Aristolochia, water and topdressing nitrogen fertilizer should be appropriate, and the amount of nitrogen fertilizer should not be too much each time. In the later stage, it is necessary to add phosphorus and potassium fertilizer to improve the quality of seedlings.

3. Late management

After planting Aristolochia, you should always loosen the soil and weed. Generally, the frequency of loosening soil is about three or four times a year, and each time it is combined with topdressing. The first topdressing of Aristolochia mainly uses nitrogen fertilizer, but the amount of nitrogen fertilizer should be controlled to avoid the white growth of Aristolochia branches and leaves. The second time is topdressing before flowering, mainly decomposed farmyard manure and a small amount of phosphate fertilizer. In the third and fourth times, phosphorus and potassium fertilizer are mainly used, which can improve the yield and quality of Aristolochia. Also, when Aristolochia grows to about 30 cm, it is necessary to build a scaffold and pull them to grow along the scaffold. Finally, in the peak season of Aristolochia, some branches that grow too vigorously but have no flower buds should be pruned reasonably to improve the utilization efficiency of nutrients.

4, pest control

We mainly want to prevent root rot and leaf spot of Aristolochia, which are basically caused by improper water management, so we need to strengthen field management and pay attention to drainage when planting. Secondly, in the early stage of the disease, bacitracin and Bordeaux mixture can be used for prevention and treatment respectively. It is also possible to encounter the damage of Aristolochia on leaves. First of all, it is necessary to do a good job in cleaning the field and use Cordyceps for prevention and control.

Aristolochia usually ripens in September 9- 10/0 every year. At this time, if Aristolochia turns from green to yellow, it indicates that the harvest time is ripe.
