Houttuynia cordata (houttuynia cordata)

Aliases: cabbage, stinky grass, etc.

Families and genera: Tripterygiaceae

Morphological features: perennial herbs, 15-50 cm high, the whole plant has a fishy smell. The lower part of the stem lies to the ground, rooting, and the upper part is erect, usually glabrous. Simple leaves alternate, leaf blade cordate, apex acute, entire; stipules membranous, linear, proximally joined with petiole to form a sheath. Inflorescence base with 4 white petaloid bracts; flowers small, without perianth. The flowering period is from May to June and the fruiting period is from October to November.

Ecological habits: sex likes a warm and humid climate. Grow well under wet and shady conditions, avoid drought, fertile sandy loam and humus loam are better when planting, and should not be planted on clay or alkaline soil.

Main points of maintenance: nitrogen fertilizer such as human dung, urine or urea was applied during the growth period of stems and leaves. In dry weather, in addition to watering every day, but also often foliar spray water, often keep the soil moist. Put it in a cool place.

Propagation methods: cutting and ramet.

Dietotherapy and efficacy: young leaves and roots are edible, it is a good vegetable, like cold raw food, can also be fried or made into soup, but also can be made into dried vegetables. The method of making dried vegetables is to dig the seedlings to remove the roots, wash them, soak them in boiling water, remove them, drain them, dry them in the sun, store them, and cook them in boiling water before eating. The whole plant can be used medicinally and has the effects of heat-clearing and detoxification, antibacterial and anti-inflammatory.

Culture methods, high-yield methods and propagation methods of Houttuynia cordata Thunb

Houttuynia cordata has two kinds of white stem and red stem, which is a common aquatic plant with high medicinal value. How much do you know about the culture of Houttuynia cordata? Do you know how to make Houttuynia cordata high-yielding? Today, the editor will introduce the culture methods, high-yield methods and propagation methods of Houttuynia cordata in detail. Let's study with the editor.

1. Seed selection: Houttuynia cordata has two kinds of white stem and red stem, the fragrance of red stem houttuynia is stronger, but its commercial value is lower than that of white stem, so it is better to choose white stem species for edible use, and it is mainly used as medicine to extract houttuynia cordata from volatile oil. this component is mainly determined by the harvest season and processing process of Houttuynia cordata Thunb, and there are no great requirements for varieties.

Second, land selection and soil preparation: Houttuynia cordata generally does not choose soil, but as mentioned earlier, limestone white sandy soil is suitable for light. It can make full use of barren hills, beaches and fields for cultivation, and shady land can also grow well. It can also be used as an orchard interplanting. After selecting the planting land, the land will be turned over, deep ploughing 20ml 25cm, every 667m2 applied fully mature organic fertilizer 2000 kg-3000 kg, calcium superphosphate 50kg, herbal ash 100kg as base fertilizer, leveling and raking fine, for a high border, the border width is 150ml 200cm, or depending on the topography, the border surface is tortoise back shape. Large and small drains should be opened according to the topography and local conditions.

Third, the method of reproduction. The method of rhizome propagation is generally adopted. It can also be propagated by seeds, but seed propagation is slow, technical requirements are high and difficult, so most of them are not used. The methods of underground stem segment (or whole rhizome) propagation and cutting propagation are mainly used in production.

1. Rhizome propagation: in the winter of the previous year or in the first or middle March of the next year, the rhizome was dug out in the wild Houttuynia cordata, or seeds were purchased elsewhere, and cut into segments of 5 murals and 10 cm long, each segment must have 3 node buds, leaving whisker roots, or whole roots. Soak the seeds in Shuangjier-GGR8 20-40mg / kg / kg produced by the Chinese Academy of Forestry Sciences for 1-4 hours, or soak the roots in 10-20mg / kg / kg / kg in transplanting for 10-30 minutes. Experiments with potatoes can increase the yield by at least 30%. For example, if the product is not available locally, soak it in 500% 10-6 rooting agent No. 3 solution for 10 minutes. In a word, a good rooting agent plays a great role in promoting the growth of the rhizome of Houttuynia cordata. According to the row spacing of 30 cm, open a shallow trench with a depth of 4.5 cm, put the rhizome into the trench according to 15 cm plant spacing, cover soil with 6mur10 cm, cover with straw 3-5 cm thick, and water the soil slightly where possible to keep the soil loose and moist. Seedlings can emerge after about 20 days, generally 80 kg-100 kg of rhizome per 667 square meters. After 10-12 months of cultivation, the ground is covered with a thick layer of rhizomes, which can produce 3000-6000kg rhizomes per 667m2. Farmers can dig them up at any time according to the market situation and finally keep the seeds.

2. Cutting propagation: cutting in the open-field seedbed in the summer high temperature season. Select a sturdy aboveground stem and cut it into 3 Mel 4-node cuttings, dozens of them are bundled into a small handful, and follow this practice with the rooting agent mentioned above, take it out and build a shed to shade the sun to maintain a relative humidity of more than 90%. After the cuttings take root and grow new leaves, the awning can be removed gradually and transplanted to the field 10-15 days later.

3. Planting: it can be planted all the year round, but it can be harvested in spring and early summer. When planting, open ditches 12-14 cm wide and 10 cm deep, with a spacing of 20-30 cm, evenly arrange the seed stems cut into small sections in the ditches every 5 cm, cover the soil, irrigate, and then cover a layer of fine soil, so that the soil is in close contact with the seed stalks, and often keep the soil moist after planting to facilitate germination and growth.

Fourth, ploughing and weeding. The weeds should be ploughed and weeded 2-3 times before the seedlings are closed. In the early stage, in order to avoid damaging the roots and seedlings, the soil can no longer be loosened at a distance of 5 cm from the roots of the plants, but weeds should be pulled out by hand to prevent weeds from competing with Houttuynia cordata seedlings for nutrients and light. It can also be sprayed on the border surface with 50% Acetochlor EC 70-75 ml and 40-45 kg of water immediately after root transplantation, which has a better weeding effect.

Fifth, cultivate the soil and protect the soil. Artificial cultivation of fishy grass on the stem up to 60-80 cm, in order to prevent plant lodging, plant height of more than 10 cm, it is necessary to cultivate soil in time to protect the grass, but also can make the underground stem stout and white.

Sixth, reasonable topdressing. In addition to applying sufficient base fertilizer before soil preparation, topdressing must be applied for 2-3 times. After the normal growth of Houttuynia cordata Thunb transplant for the first time, the seedlings were yellowish green, and fertilizer should be applied immediately. Nitrogen fertilizer should be applied mainly at the seedling stage. 1000-1500 kg of light human and animal manure water was applied to the roots of urea every 667m2 to promote the rapid growth of seedlings. The second time was increased to 2000 kg in mid-April, and 13-15 kg of urea and 10 kg of potassium sulfate were added to Houttuynia cordata Thunb plants to meet the rapid emergence of aboveground stems and a large number of branches and leaves, as well as the rapid germination of axillary buds of underground stems, and to meet their needs for potash fertilizer. For the third time, in the early stage of booting and flowering in mid-May, 50 kg of rotten cake fertilizer powder was mixed with 30 kg of superphosphate and 500 kg of fire ash every 667 square meters. Houttuynia cordata Thunb is a potassium-loving plant, using the method of foliar topdressing during the growing period, spraying 0.2% potassium dihydrogen phosphate solution and other micro-fertilizer on the plant for 2-3 times. During the growth and expansion period of root tuber, Shuangji-GGR8 10-15mg ·kg-1 was sprayed for 2-3 times.

Seventh, drain waterlogging and prevent heat. Houttuynia cordata Thunb likes to be moist and can not bear drought, so it is required to keep the soil moist during the growing period; in the high temperature and rainy season, it is necessary to prevent stagnant water and pay attention to timely drainage and high temperature prevention.

The above is all I know about Houttuynia cordata today. I hope it will be helpful for flower friends to read this article. If you want to know more about Houttuynia cordata, please continue to pay attention to the succulent flower bed, we will provide you with more related knowledge!

Culture methods and matters needing attention of Houttuynia cordata Thunb

Cultivation methods of Houttuynia cordata Thunb

Select sandy loam with loose fertilizer, convenient drainage and irrigation, leeward and sunny soil or soil rich in organic matter for cultivation. After deeply ploughing and loosening the soil, the border will be 1.5 mi 1.6 meters wide, 30 cm high and 20 cm wide at the bottom of the ditch. Farm soil miscellaneous fertilizer 3000ml / mu was applied as base fertilizer, shallow trenches or holes were dug according to plant spacing of 14 × 20cm, and watered after planting to keep the soil moist.

Administration and Management

In case of drought in the seedling stage, it should be watered sooner or later. Before the seedlings survived, weeding and topdressing were ploughed and topdressing for 3 times, and the fertilizers were mainly nitrogen fertilizers such as human feces, urine or chemical fertilizers.

Each time weeding combined with topdressing, 1000 kg per mu of human feces and urine or 25 kg of urea, dilute at first and then concentrated.

Nitrogen fertilizer is mainly applied after harvest every year to promote plant germination; the second time is to apply phosphorus and potassium fertilizer and cultivate soil to survive the winter so as to lay a good foundation for germination in the coming year.

Harvest and processing

The tender houttuynia cordata was harvested from March to May for consumption. If it is mainly used for medicinal purposes, it can only be harvested once in the same year, and it can be harvested from September to October. It can be harvested twice in the second year, the first in June and the second from September to October.

If the beverage is processed, the whole grass can be cut flat with a sickle, washed and dried, according to the requirements of the production process.

Propagation method of Houttuynia cordata Thunb

The seed germination rate of Houttuynia cordata is not high, the germination is suitable for 17-25 ℃, and the germination rate is about 20%, so ramet, cuttings and rhizomes are often used to propagate. In addition, Houttuynia cordata Thunb is rarely planted by families, and most of them are propagated in large numbers.

Ramet propagation

From late March to April, the ramet of the mother plant can be dug up and transplanted on the seedbed of sandy soil or directly transplanted.

Cuttings propagation

In spring and summer, sturdy branches without disease and insect pests can be cut as cuttings, cut and grow 125cm, at least three nodes, cuttings on the seedbed of sandy loam, with a row spacing of 16 × 10 cm or 14 × 10 cm. Watering after insertion, shading, rooting and transplanting seedlings.

Rhizome propagation

Can be carried out in February to March, dig excellent white, stout rhizome, cut into small segments with more than 2 axillary buds, in the seedling bed or field open shallow trench seedlings or planting.
