Planting techniques and mu income of Ophiopogon japonicus

Planting techniques: Maidong should choose loose, fertile and well-drained sandy loam for planting, not continuous cropping. Divide the tuber root and whisker root into a single plant, cut off the residual whisker root, cut off part of the rhizome and plant it immediately. If you can't plant it immediately, you must raise seedlings. The planting time is better from April to May, which can be planted by trenching strips or holes. The Beginning of Spring needs to be irrigated 1-2 times before and after, and stagnant water should be drained actively in summer. Mu income: the general mu income is about 15000-20000 yuan.

I. planting techniques of Ophiopogon japonicus

1. Land selection and preparation

The main results are as follows: (1) the cultivation of Ophiopogon japonicus should choose loose, fertile, moist and well-drained sandy loam soil, or sloping land for cultivation.

(2) the planting of Ophiopogon must not be continuous cropping, and the soil preparation should be carried out in time after the current crop harvest, so that the land can be loose, broken and vouched.

(3) if the area of the field is too large and the soil surface is uneven, small ridges can be built to facilitate drainage and irrigation.

2. Seed and seedling

The main results are as follows: (1) Ophiopogon japonicus is often propagated by ramet. Sichuan was planted before and after Ching Ming Festival and Zhejiang was planted during the period from the Beginning of Summer to Grain in Beard.

(2) when digging Ophiopogon japonicus, it is necessary to choose the dark green plant to cut off the tuber root and whisker root into a single plant, cut off the residual whisker root, cut off part of the rhizome and plant it immediately.

(3) if it cannot be planted immediately, it is necessary to raise the seedlings, soak the stem base of the seedlings in water, make them absorb enough water, and then stand on the dug loose soil in the shade, and cover the soil around for preservation.

(4) if the temperature is too high, watering can be carried out every day or every other day. In addition, it should be noted that the time for raising seedlings should not exceed 7 days.

3. Planting

The main results are as follows: (1) most of the plants are planted in Sichuan in April and in Zhejiang in May, and they are usually planted in sunny or cloudy days.

(2) trenching and strip planting is adopted in Sichuan area, and the row spacing is about 15 cm and the depth is about 5 cm.

(3) Hole planting is mostly used in Zhejiang, the depth of the hole is 3 cm-5 cm, the row spacing is about 25 cm, and the plant spacing is about 15 cm. Generally, 9-10 seedlings were planted in each hole.

4. Intercropping

The main results are as follows: (1) Ophiopogon needs to grow in a shady and humid environment, and intercropping is carried out in all the main producing areas.

(2) Maize is usually planted in Sichuan between summer and autumn. the row spacing of corn is about 50 cm. 1-2 seedlings are left in each litter after emergence, and 1 plant is better to be harvested before the Beginning of Autumn.

(3) Winter and early spring are the growing period of root tuber of Ophiopogon japonicus, and crops are generally not planted in order to avoid affecting the yield of Ophiopogon japonicus.

(4) in Zhejiang area, the distance between rows and plants is relatively wide, and the growth time is long, and the main intercropping crops are watermelon, broad bean and so on. Generally, intercropping is carried out in the first and second year, but not in the third year, so as not to affect the yield and quality of Ophiopogon japonicus.

5. Irrigation

The main results are as follows: (1) after the Beginning of Summer, the weather becomes hotter and the water evaporation becomes larger, so it should be irrigated in time.

(2) there is little precipitation in spring and winter, and drought is easy to occur. It is necessary to irrigate 1-2 times before and after the Beginning of Spring to promote the growth of root tubers.

(3) Rain Water is relatively concentrated in summer, so the stagnant water in the field should be removed in time to prevent diseases and insect pests in the hot and humid weather so as to affect the production.

Second, the mu income of Ophiopogon japonicus.

Generally speaking, Ophiopogon japonicus can produce 1500-2000 kg per mu of fresh Ophiopogon japonicus. According to the current market purchase price of 9-10 yuan, the income per mu can reach 10-20 thousand yuan.

In addition, Ophiopogon seedlings are currently about 6 hair per kilogram, and each mu of Ophiopogon seedlings can be sold for about 3000 yuan. In general, the mu income of planting Ophiopogon japonicus ranges from 15000 yuan to 20000 yuan.
