" (2) Don't record: "Girls are like leeks in winter, and in winter, they are born in the valley of faith, the valley of Sichuan and the fertile earth and stone in Diban. Harvest in February, March, August and October, and dry in the shade. " (3) Tao Hongjing: "Hangu Pass is the Qin Pass, and winter wheat is different from the name of sheep leek, and it is everywhere. It is picked in April. The moon in winter is like a green pearl, and its roots are like wheat. Therefore, it is called Maimendong, and it is better to be fat. " ④? Compendium of Materia Medica: "Maimendong, out of Jiangning, Xiaorun; Out of Xin' an, Dabai. Its big seedlings are like deer onions and small ones are like leeks. There are four similar in size and function, and their sons are round and blue. " ⑤ "Materia Medica": "Maimendong has it today. Julia is like sedge, more than a foot long. It was not carved in the four seasons. Its roots are yellow and white, and it has fibrous roots. It is shaped like a lotus. In April, it blooms reddish flowers. How can it bloom in the first place? It is really blue and round like a pearl. " 6 "Outline": "Maimen Cave, the ancients only used wild people, and most of them were planted by later generations.

[Edit this paragraph] Ophiopogon japonicus Botany

[Edit this paragraph] (1) Overview

Alias Maimendong.

Ophiopogon japonicus saponin (Liliaceae? Japan? (thunb。 )ker。 -Gav. ) In winter, root tuber is used as medicine. Function of nature and taste: sweet, slightly bitter, cool in nature, nourishing yin and promoting fluid production, moistening lung and relieving cough, clearing away heart fire and relieving annoyance. Indications: fever, irritability, thirst, dry throat and lung heat, cough and tuberculosis. Location: Sichuan, Zhejiang. Grass is distributed in most provinces except the northeast. Ophiopogon japonicus is distributed in Jiangxi, Anhui, Zhejiang, Fujian, Sichuan, Guizhou, Yunnan, Guangxi and other places.

[Edit this paragraph] (2) Plant characteristics

Liliaceae perennial herbs, tufted, about 30 cm high. The leaves are clustered, slender, dark green and shaped like leeks. Flowering stems are born from leaves, and the flowers are small and lavender, forming racemes. The fruit is a berry, spherical, and dark green or dark blue at maturity. The rhizome is short, and there are many fibrous roots, which often expand into spindle-shaped fleshy roots at the middle or top of fibrous roots, that is, medicinal Ophiopogon japonicus.

(3) Growth characteristics

Like a warm and humid climate, the average annual temperature in the main producing areas of Ophiopogon japonicus in Sichuan and Zhejiang is between 16 ~ 17℃, and the annual rainfall is above1000 mm. Plants with a temperature of-10℃ in winter will not be frozen, but their growth and development will be inhibited, which will affect the growth of root tubers. Although it can grow well in mountainous areas or north China where the temperature is low all the year round, its tuberous roots are small and few. Should be slightly shaded, under strong sunlight, leaves turn yellow, which is not conducive to growth and development. However, if it is too shaded, it is easy to cause the overground part to grow in vain, which is also unfavorable for growth and development. Drought and waterlogging have significant adverse effects on the growth and development of Ophiopogon japonicus. Loose, fertile and well-drained soil, sandy loam, sandy and cohesive soil are not suitable for planting Ophiopogon japonicus. Avoid continuous cropping, it will take 3 ~ 4 years to replant.

[Edit this paragraph] (4) Cultivation techniques

1. Land selection and preparation

Before being used as kohlrabi, cabbage, cotton, radish, wild pea, etc. It is usually required to plough the land three or four times after harvesting to make the soil loose and fine, which is conducive to root growth. Then level the ground, make the ridge 130- 160 cm wide, and make the ditch about 33 cm wide. When preparing soil, apply base fertilizer, and use 37,500-45,000 kilograms of manure per hectare.

2. Breeding method

Reproduction by ramets. Each mother plant can be divided into 1 ~ 4 seedlings.

(1) seedling raising

There are many varieties of Ophiopogon japonicus cultivated in various places. According to the investigation, Ophiopogon japonicus varieties developed in Suining, Sichuan Province have strong disease resistance and high yield. Fine varieties can be selected all over the country. When Ophiopogon japonicus is harvested, the seedlings with cut roots will be selected as seeds. Cut off the lower part of the rhizome and the fibrous root with a knife, and keep the upper part of the stem node as long as the leaves are not scattered. Its cross section is white and radial (commonly known as chrysanthemum heart). Roots should not be left too long, otherwise, after cutting, double-stem nodes (commonly known as tall-footed seedlings) will appear, resulting in less tubers and low yield. After the roots are cut off, the qualified seedlings are sorted out and planted with straw. Zhejiang believes that leaves are too long, which will consume the water of seedlings and is inconvenient to operate. So cut off the leaves above, leaving only 5-6 cm long, and cut off all the roots.

The general harvest of Ophiopogon japonicus is 1 hectare, and 3 ~ 4 hectares can be used as seedlings. When the seedlings are ready, they should be planted immediately. If you can't plant them right away, you should tie them up and soak them in water, enclose them with a little soil, and spray a little water every day for a few days.

(2) Planting

The suitable planting period of Ophiopogon japonicus in Sichuan is April, and it is from May to early June in Zhejiang. When planting Ophiopogon japonicus in Sichuan, first ditch, the row spacing is 10 ~ 13 cm, and the ditch depth is about 5 ~ 6 cm. Put 2 ~ 4 seedlings in the ditch every 6 ~ 8 cm and put them vertically in the ditch. Then, fill the shallow ditch with soil, push it with a flat hoe or step on it with your feet, and compact the covering soil on both sides of the seedlings. Water it once immediately after cutting, and the seedling per hectare is about 10500 kg. When planting Ophiopogon japonicus in Zhejiang Province, the soil should be cut and ditched with a seed knife. The row spacing of two-year harvest is 20cm * 16cm, and the row spacing of three-year harvest is 26-33cm * 20-23cm, and 8-9 plants are planted in each hole. The base of the same clump of seedlings should be neat and buried vertically, and then compacted to a depth of about 4cm.

Step 3 mix cropping

In the main producing areas of Ophiopogon japonicus, the majority of drug farmers are used to intercropping in Ophiopogon japonicus fields, which can not only increase income, but also benefit the growth of Ophiopogon japonicus, and intercropping can reduce direct sunlight. Sichuan production areas generally interplant double-season corn in summer and autumn (Ophiopogon japonicus interplants one row of corn every six rows) and garlic in winter.

4. Tian Tuan management

(1) intertillage weeding

Ophiopogon japonicus plants are short, and weeds will breed and hinder the growth of Ophiopogon japonicus if weeds are not regularly weeded. Weeding should be done once half a month after mowing. Weeds are easy to grow in May ~ 10, and weeds need to be weeded 1 ~ 2 times a month. After winter, there are fewer weeds, which can reduce the frequency of weeding. Weeding should be combined with weeding to loosen the ground.

(2) Topdressing

Ophiopogon japonicus has a long growth period and needs more fertilizer. In addition to applying sufficient base fertilizer, topdressing should be done in time according to the growth of Ophiopogon japonicus. Generally, topdressing is more than 3 times, and the first time is in mid-July. Apply 30,000 ~ 37,500 kg of pig manure and 750 ~ 1.500 kg of decomposed cake fertilizer per hectare. For the second time, in early August, 37,500-45,000 kg of pig manure urine, 750- 1500 kg of decomposed cake fertilizer and 0/500-2,250 kg of plant ash/kloc were applied per hectare. At the beginning of the third time 165438+ 10, 30000 ~ 37500 kilograms of pig manure and 750 grams of decomposed cake fertilizer were applied per hectare. When topdressing, nitrogen fertilizer should not be too much, so as not to cause the overground part to grow white. In Zhejiang producing areas, in addition to the base fertilizer, some calcium superphosphate was applied in the hole when planting, and it was mixed into the soil to increase the yield. When the late crop of Ophiopogon japonicus turns green, clean water 1 1250 kg, calcium superphosphate 1 12.5 kg should be applied per hectare, and human manure 18750 kg and calcium superphosphate 195 kg should be applied per hectare in July. Spring and autumn are the periods when the root tuber expands and the rhizome elongation increases, and the percentage is also strong. At this time, phosphorus and potassium fertilizer should be applied again. Therefore, topdressing should be carried out in March and September every year. First, loosen the topsoil, apply 750 ~ 1500 kg of superphosphate or decomposed cake fertilizer per hectare, and then apply 65438 18750 ~ 22500 kg of human excrement and urine.

(3) Irrigation

Ophiopogon japonicus needs more water to be irrigated in a slightly moist soil environment. After planting, in addition to infiltrating the soil in time, it should be irrigated in time in early May, when the weather is dry and hot and the soil moisture evaporates quickly. In case of drought in winter and spring, 1 ~ 2 times should be irrigated before early February to promote root growth.

[Edit this paragraph] 5. Pests and diseases and their control

(1) black dot

The pathogen is a semi-unknown fungus. At the early stage of the disease, the blade tip turned yellow and spread downward, resulting in blue and white wet spots with different colors, and all the leaves turned yellow and died in the later stage.

Control methods: ① Select disease-free seedlings and soak them in 1: 1: Bebordeaux solution or 500 times 65% zineb wettable powder for 5 minutes before planting. (2) Strengthen field management and eliminate stagnant water in time. (3) During the onset period, diseased leaves can be cut off in the field, and Bordeaux mixture 10 ~ 14 days can be sprayed for 3 ~ 4 times in a row.

(2) Root-knot nematode disease

The pathogen is a root-knot nematode of Nematoda. The main damage to the roots, causing gall, makes the fibrous roots of Ophiopogon japonicus shorter, and later becomes rough, cracked and reddish brown. When the swollen part is cut open, a large number of milky white shiny spheres can be seen, which are female adults.

Prevention and control methods: ① Implement crop rotation, which can be rotated between paddy fields and dry land crops where conditions permit, and avoid rotating with crops such as flue-cured tobacco, Chinese milk vetch, beans, taro, sweet potato, melon, Siraitia grosvenorii, Atractylodes macrocephala, Salvia miltiorrhiza and belladonna, and it is better to rotate with gramineous crops. ② Select disease-free seedlings and cut off old roots. ③ Selection of disease-resistant varieties, such as Ophiopogon japonicus, Ophiopogon japonicus and Ophiopogon japonicus. ④ Soil treatment can be prevented.

(3) For grubs, grubs, needle worms, cutworms, etc. , please refer to the part of ginseng diseases and insect pests and their control.

[Edit this paragraph] (5) Harvest and processing

After planting Ophiopogon japonicus, it can be harvested in April of the following year. Turn over the whole plant of Ophiopogon japonicus with a hoe or plow for 23-26 cm in sunny days, then shake off the soil at the root, cut off the root tuber and fibrous root with a knife, put them in the washing basket respectively, put them in running water, wash them with your feet and transport them back to processing. Zhejiang Ophiopogon japonicus is harvested in the third or fourth year after planting, and the method is similar to that of Sichuan Ophiopogon japonicus producing area.

The processing of Ophiopogon japonicus is to expose the cleaned roots to the sun on a drying mat or threshing floor, dry the water vapor, gently rub them with both hands (don't break the epidermis), rub them again after rubbing, and repeat them for 5-6 times until the fibrous roots are removed. After drying in the sun, use a sieve or windmill to remove the broken fibrous roots and impurities, and select the tuberous roots for sale. General dry goods 1, 500 ~ 2,250 kg/ha, but in recent years, the yield can reach 3000 ~ 3750 kg/ha by using Suining Ophiopogon japonicus variety.

The processing method of Zhejiang Ophiopogon japonicus is to dry the cleaned tuberous roots for 3-5 days, gradually dry the fibrous roots from soft to hard, put them in the laundry basket for 2-3 days, and then turn them over for 3-5 days. At this time, it is necessary to dry in piles and turn it frequently to facilitate even drying. After that, it will be stuffy for 3 ~ 4 days, and then it will be dried for 3 ~ 5 days. This will be repeated for 3 ~ 4 times continuously, and the dryness of the root tuber will reach 70%, so that the fibrous root can be cut off and dried. When the weather is bad, it should be dried with low fire at 40 ~ 50℃. After 15 ~ 20 hours, it should be taken down and left for a few days before drying.

The dried Ophiopogon japonicus is packed in wooden cases or sacks for easy storage and transportation. It should be kept in a dry place to prevent moisture and insects.
