The latest course of high-yield planting techniques of Ophiopogon japonicus

Ophiopogon japonicus is a kind of Ophiopogon japonicus originating from Japan and home. Ophiopogon japonicus is distributed in many countries. Ophiopogon has the effect of clearing heat and detoxification and moistening the lung and relieving cough. The small rhizome of Ophiopogon japonicus is traditional Chinese medicine, so how can Ophiopogon japonicus be planted to produce high yield? Next Shuai Shuai will tell you about it!

I. the environment of origin

The origin of Ophiopogon japonicus is still in China, and in many places in China, such as Guangxi, Guangdong, Fujian, and so on, it is also related to the growth environment and altitude that Ophiopogon japonicus adapts to. There seems to be a little more in Guangdong Province. Ophiopogon generally likes to settle and grow in hillside grass below 2000 meters above sea level or in some shady and humid places, relatively close to wet areas with water sources.

II. Land selection and preparation

The soil planted by Ophiopogon japonicus should choose fertile, moist and well-drained soil. Ophiopogon japonicus can not sit together. If the soil has been planted before, the soil should be prepared, then the soil will be finely crushed and leveled, and then compost can be added, or calcium phosphate can be used.

3. Planting methods

1. Seed and seedling

The reproduction of Ophiopogon is generally propagated by individual plants. When selecting plants, we should select robust plants, then cut off the fibrous roots, divide them into individual plants, cut off the residual whisker roots, and then plant them. The time can not be too long. Put the plant in clear water to absorb water and insert it in the loose soil, then cover the soil, and finally put it in a cool place, watering it once a day.

2. Planting

Planting choice in non-rainy days, using trench strip planting, now ditch applied thin pig manure water, and then plant seedlings, a clump of 3 plants, after planting, cover the soil, compaction, the seedlings will be fixed.

IV. Field management

1. Intercropping

The main producing areas of Ophiopogon use the way of intercropping, planting corn in spring and summer, planting a row of corn every five rows of Ophiopogon, growing in Ophiopogon so as not to affect the yield of Ophiopogon.

2. Ploughing and weeding

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

3. Irrigation

When the weather is hot in summer, the evaporation of water is very large, so it is necessary to replenish water to crops in time. Drought is easy in winter, and irrigation should also be carried out. On rainy days in summer, drainage should be actively done to prevent water from accumulating and rotting roots, resulting in diseases and insect pests, etc., affecting the growth of Ophiopogon japonicus.

5. Diseases and insect pests

1. Disease

Black spot: this is a fungus that spreads. It harms the leaves of Ophiopogon japonicus. It usually parasites on the leaves of Ophiopogon japonicus and begins to move in April of the following year. It makes the plants sick and leaves will die. We can spread plant ash, and then soak and spray the seedlings with Bordeaux solution and Dysenamine wettable powder.

Root-knot nematode disease: this is a disease that harms the root. If possible, it can be rotated by flood and drought, and disease-resistant healthy seedlings can be selected to disinfect the soil.

2. Insect pests

Insect pests are generally grubs, mole crickets, ground tigers and golden needle worms, which are harmful to the rhizome. Rotation with rice is adopted to control them, and pesticide spraying is used.

These are the high-yield planting techniques of Ophiopogon. Ophiopogon should choose the location and soil at the beginning of land preparation. If the land is not selected well, it will affect the growth of crops behind, and the quality of some land is already very poor. If it is reused, it may cause the continuous occurrence of diseases and insect pests, poor soil fertility and other phenomena. I hope this article can help you.
