Detailed Explanation of Key Points for High-Yield Ophiopogon Japonicus Cultivation Techniques

Ophiopogon japonicus is native to Japan and China, and it is distributed across multiple countries. Ophiopogon japonicus has the effects of clearing heat and detoxifying as well as moistening the lungs and relieving cough in humans. The small tuberous roots of Ophiopogon japonicus are used in traditional Chinese medicine. So how should Ophiopogon japonicus be planted to achieve high yield? Below, Shuaishuai will tell everyone about it!

I. Production Area Environment

The place of origin of Ophiopogon japonicus is still China, and it is found in many places in China such as Guangxi, Guangdong, and Fujian, which is also related to the growth environment and altitude that Ophiopogon japonicus adapts to. It seems there are somewhat more areas in Guangdong Province. Generally, Ophiopogon japonicus likes to settle and grow in hillside grass clusters below 2000 m in altitude or in some shady and damp places, relatively close to moist zones with water sources.

II. Land Selection and Soil Preparation

For planting Ophiopogon japonicus, the soil should be fertile, moist, and well-drained. Ophiopogon japonicus land cannot be continuously cropped. If crops were previously planted on the land, the soil must be prepared, then the soil should be made fine and level, and then compost should be added. Calcium phosphate can also be used.

III. Planting Methods

1. Seedlings

Propagation of Ophiopogon japonicus generally uses division propagation. When selecting plants, robust plants should be chosen, then their fibrous roots should be cut off and divided into individual plants, and the remaining fibrous roots should be trimmed. Then they can be planted. The time must not be too long. Place the plants in clean water to absorb some moisture, then insert them into loose soil, then cover with soil, and finally place them in a cool place, watering once a day.

2. Planting

Planting should be done on non-rainy days, using furrow strip planting. First apply dilute pig manure water in the furrow, then plant the seedlings, planting 3 plants per clump, and after planting, cover with soil, compact it, and fix the seedlings in place.

IV. Field Management

1. Intercropping

The main production areas of Ophiopogon japonicus all use intercropping. Corn is planted in spring and summer, with one row of corn planted every five rows of Ophiopogon japonicus. During the growth of Ophiopogon japonicus, crops are generally not interplanted, so as not to affect the yield of Ophiopogon japonicus.

2. Cultivation and Weeding

Weeding should be carried out once half a month after planting seedlings, and from the second half of the year until October, weeding should be done once a month, because weeds grow wildly during this period.

3. Irrigation

In summer, once the weather gets hot, water evaporation is very high, so crops should be replenished with water in time. In winter, drought is very likely, so irrigation should also be carried out. In summer, during rainy days, drainage work should be actively done well to prevent water accumulation from causing root rot, pests and diseases, and other problems, affecting the growth of Ophiopogon japonicus.

V. Pests and Diseases

1. Diseases

Black spot disease: This is a fungal disease spread by fungi. It harms the leaves of Ophiopogon japonicus, generally parasitizing on the leaves of Ophiopogon japonicus, and begins activity in April of the following year, causing the plants to become diseased, and the leaves all wither and die. We can sprinkle plant ash, then use Bordeaux mixture and amobam wettable powder to soak the seedlings and spray.

Root-knot nematode disease: This is a disease that harms the roots. If conditions permit, paddy-upland rotation can be used, disease-resistant healthy seedlings can be selected, and the soil can be disinfected.

2. Insect Pests

Insect pests generally include white grubs, mole crickets, cutworms, and wireworms. These are all insects that harm roots and stems. Rotation with rice can be adopted for prevention and control, and pesticides can be used for spraying.

The above are the high-yield cultivation techniques for Ophiopogon japonicus. At the very beginning, when selecting land and preparing soil for Ophiopogon japonicus, the location and soil must be chosen well. If the land is not chosen well, it will affect the later growth of the crops. Moreover, some land is already very poor in quality. If it is used again, it may cause continuous outbreaks of pests and diseases, poor soil fertility, and other phenomena. I hope this article can help everyone.
