How to plant Ophiopogon japonicus

The taste of Ophiopogon is a little bitter, but its effect is very strong. Eating Ophiopogon has the benefits of lowering blood sugar, lowering blood pressure, moisturizing the lungs and relieving thirst. At present, Ophiopogon is selling very well in the market, so many people want to increase economic benefits by planting it. Then the first step is to understand its planting technology.

How to plant Ophiopogon japonicus

1. Growth habits: Ophiopogon prefers warm and humid environment. The sandy loam with loose, fertile and good drainage is better. It should be properly shaded in the early stage of growth. if the strong light is direct, the leaves will turn yellow and the growth and development will be affected. Able to withstand 0 ℃ low temperature, moisture resistance, fertilizer resistance.

2. Land selection and preparation: choose sandy loam with convenient drainage and irrigation, loose and fertile soil. After ploughing and harrowing many times, 2000,000kg of farm manure is applied per mu, and the border is raked evenly, with a width of 1 to 1.2 meters and a height of about 20 centimeters.

3. Split propagation: the old plant was dug up before and after the Qingming Festival, the tuber root, fibrous root and old rhizome were removed, and the tufted plant was divided into a single plant. First soak the seedlings in clean water for 10 minutes, then plant them in holes according to the row spacing of 16 cm X 26 cm. 6 seedlings are planted in each hole, with a depth of about 3 cm, and then irrigated with fixed root water.

How to plant Ophiopogon japonicus

1. Planting time: the suitable planting period of Ophiopogon japonicus is from late March to early April in Sichuan and from May to early June in Zhejiang.

2. Planting method: when planting Ophiopogon in Sichuan, first trench according to row spacing of 10-13 cm, depth of 5-6 cm, put 2-4 seedlings in the ditch every 6-8 cm, put them vertically in the ditch, and then fill the shallow ditch with soil, push with a flat hoe or step on with your feet to press the covering soil on both sides of the seedling. Immediately after cutting, it will be watered once, and about 10500 kg of seedlings will be needed per hectare. When planting Ophiopogon in Zhejiang, first cut the soil and open the ditch with a seed knife, the row spacing of the two-year harvest was 20 cm * 16 cm, and that of the 3-year harvest was 26 cm * 20 cm. 9 seedlings were planted in each hole, and the same cluster of seedlings should be neat at the base and buried vertically, and then compacted with a depth of about 4 cm.

3. Reasonable intercropping: in the main producing areas of Ophiopogon japonicus, the vast number of medicine farmers are used to intercropping in the field of Ophiopogon japonicus, which can not only increase their income, but also benefit the growth of Ophiopogon japonicus, and intercropping can reduce the direct sunlight. Sichuan producing areas generally interplant two crops of corn in summer and autumn (interplanting one row of corn in every 6 rows of Ophiopogon japonicus) and interplanting garlic in winter.

4. Watering to protect seedlings: Ophiopogon likes moist soil, especially immediately after planting, so that the soil and the base of the seedling are fully in contact with each other, so that the roots can survive early and can be watered again after a few days. In general, water can be turned green in 15 days, and water can be watered in time in the rainy season to prevent rotting roots.

How to fertilize Ophiopogon japonicus

Ophiopogon japonicus has a long growth period and needs more fertilizer. In addition to applying sufficient basic fertilizer, topdressing should be applied in time according to the growth situation of Ophiopogon japonicus. Generally, topdressing more than 3 times, the first time is in mid-July. The second time is in early August and the third time is in early November. Nitrogen fertilizer should not be too much when topdressing, so as not to cause overgrowth of aboveground parts. In Zhejiang producing area, in addition to base fertilizer, some superphosphate was applied in the hole and mixed in the soil to increase the yield. In spring and autumn, root expansion and rhizome elongation increased, and the percentage was exuberant, so phosphorus and potash fertilizer should be applied again at this time.

Pest control of Ophiopogon japonicus

1. Mole cricket. It is commonly known as "native dog". Both adults and nymphs can bite the roots of seedlings. Three generations a year, overwintering as adults or nymphs. It began to happen from March to April the following year. More in the nocturnal activity, like to fly, phototaxis and feces. Control method: ① before planting combined with soil preparation, per mu with 50% phoxim EC 0.5kg, add water into 800x liquid, spray the soil surface, and turn the topsoil into the soil. During the growing period of ② Ophiopogon, 3 kg of 5% phoxim granules or 3 kg of 5% methyl isophos granules were used per mu, and 20-30 kg of fine soil were mixed and scattered evenly on the border soil. ③ was trapped and killed with spices.

2. Grub. It generally occurs from August to September, harming the roots and seedlings and affecting the growth. It can be sprayed with 200 times of 90% trichlorfon.

As long as you master the planting method of Ophiopogon japonicus, it is still very easy to grow. It is necessary to understand its growth habits before planting, and then choose the appropriate time to plant. After planting, there should be timely additional fertilization. Ophiopogon is also vulnerable to insect pests, so pest control should also be done.
