Breeding methods and management of Scutellaria barbata

Scutellaria barbata is also called sunflower, because the flowers of Scutellaria barbata bloom when there is plenty of sunshine, and they are closed when the light is weak in cloudy days, evening and early morning. Because the flower shape of Scutellaria barbata is like peony and its leaves are like pine needles, there is another name for dragon beard peony or pine leaf peony.

Scutellaria barbata

Scutellaria barbata is usually propagated by sowing or cutting, sowing indoors in the sun in March or live in the courtyard in April. The suitable temperature for seed germination is 20ml 25 degrees, which can germinate in about one week. After the seedlings come out, the seedlings can blossom in about two months after a little inter-seedling or transplanting, and the young stems can be removed during the growing period, which can take root easily and blossom quickly; it is very easy to restore growth after transplanting, so large seedlings can also be transplanted with bare roots. The main florescence is from July to September, and the small capsule is mature from August to October. The peel-like cap-shaped fruit split horizontally when ripe, followed by tiny silver-gray seeds. Some Corolla has fallen off, when the top cover of the capsule is straw yellow, it has also matured; we should pay attention to timely harvest.

Scutellaria barbata is a cross-pollinated plant, sowing and reproduction is difficult to maintain the purity of one or two seed pairs, attention should be paid to the elimination of single-petal and floret plants.

The family is more in the windowsill, balcony with shallow pot planting, cultivate into a meticulous and exquisite small potted flowers.

In summer and autumn, whether in the flower beds in the garden, next to the house or in front of the window, you can often see an ordinary little flower. Although it is not expensive, it is lovable. In the hot summer, it is not afraid of the scorching sun, blooming with a bright smile, colorful, vibrant and often blooming. What is more valuable is that its vitality is extremely tenacious. In summer, if you put a few inches of twigs in a flowerpot, you will be able to produce delicate flowers the next day! Some people jokingly

Call it "immortal", "choke not to death"; although its name is indecent, it is actually indomitable to its vitality.

Praise and praise.

The stems and leaves of Scutellaria barbata are fleshy and clean, colorful and colorful, and the flowering period is longer, which can be called an ideal flower bed edge material, can also be used as a special kind of flower bed, but also suitable for potted plants. From summer to autumn, the flowers are in bloom, colorful and enjoyable.

Scutellaria barbata is an annual herb of Portulacaceae, which is native to South America and Brazil and has been widely cultivated in China. It is 10 to 15 centimeters high. The stem is thin and round, creeping or growing upward, leaves alternate or scattered, fleshy cylindrical. Peanuts at the top of the branch, flower diameter 3-4 cm, petals bright color, there are red, white, purple, yellow and other colors, as well as inlaid with several color patterns. It can be divided into double, semi-double and double. It blossoms from June to September. The sunrise opens and closes in the afternoon. The fruit is a capsule, and the capsule is easy to crack and scatter when it is mature, so pay attention to collecting and leaving seeds.

Scutellaria barbata prefers warm, dry, sunny and well-ventilated environment. Highly adaptable and easy to manage.

Scutellaria barbata can tolerate barren and dry soil, and potted sandy loam with good drainage.

For good.

Scutellaria barbata is a strong positive plant, like sunlight, not shade-tolerant, such as indoor or semi-shady environment, must not grow well or rarely blossom.

Watering should not be excessive during maintenance, and the basin soil is usually semi-dry.

Wet is better, too much water is easy to rot the root.

During the growth period, thin liquid fertilizer can be applied every 3 to 4 days to make it grow healthily and bloom luxuriantly.

Scutellaria barbata can be propagated by sowing or cutting.

Seeds can be sown in spring, summer and autumn. The seeds germinate when the temperature is above 20 degrees and germinate about 10 days after sowing. When 4-5 leaves are grown, the seedlings can be transferred and planted, from sowing to flowering.

It will take 2 months.

Cuttage propagation is often used for double petal varieties. The cut branches will be used as cuttings in summer, and the wilted stems can also be used. It is very easy to cut and survive, and flower buds can appear quickly.

Ecological environment.

It is more common in ditch side, field edge and roadside damp place. Too dry soil is not good for growth. Scutellaria barbata prefers a warm and humid climate and does not require high soil conditions. Born on the edge of paddy fields, streams or wet grass, below 2000 meters above sea level. Scutellaria barbata likes warm climate and humid, semi-overcast environment. It is better to cultivate sandy loam or humus loam with deep, loose, fertile and well-drained soil. Heavy soil and low-lying plots prone to stagnant water are not suitable for planting. It is often wild near fields or ditches in hilly and flat areas. Like relatively humid environment, too dry areas grow poorly.

Harvesting and storage

Those propagated with seeds can be harvested once in May and 7.9 months every year from the second year. If the ramet is propagated, it will be harvested once in September of that year, and then it can be harvested three times a year. When harvesting, cut the whole plant with a sickle, pick out weeds, tie them into small handfuls, and dry them in the sun or in the shade.

Storage and maintenance: place in a dry place.

Sexual taste function

Bitter, bitter, cold. Return to the meridians of the lung, liver and kidney. Function and main treatment of heat-clearing and detoxification, removing blood stasis and diuresis. For swollen sore, sore throat, snakebite, fall pain, edema, jaundice. Usage and dosage 15-30g, fresh products 30-60g; proper amount of fresh products for external use, apply to the affected area.

Planting technology

1. Land selection and land preparation

It is better to plough loose and fertile sandy loam or loam. At the same time, 2000 kg of farm manure is applied per mu as base fertilizer.

2. Methods of reproduction

Seed propagation is the main method, and ramet propagation can also be used. The main results are as follows: (1) seed propagation is mostly direct seeding, from late September to early October, strip sowing or hole sowing. Strip sowing is ditched according to the row spacing of 25-30 cm, and the ditch depth is about 4 cm; the hole seeder opens the hole according to the hole spacing of 27 cm. When sowing, first sow the seeds in the plant ash mixed with animal dung water, mix them into seed ash, and then evenly scatter the seeds in the ditch or hole, covered with a layer of fine soil or plant ash, the thickness shall not exceed 0.5 cm. After sowing, the soil should be kept moist before emergence, and the seedlings can emerge about 20 days after sowing. Use 1.5-2 kg of seeds per mu. (2) ramet propagation is carried out in spring and summer. Dig up the old roots of the plant, select strong, pest-free plants for split, each plant has 3-4 seedlings, according to the hole distance of about 27 cm hole planting, cut and watered.

3. Field management

The main results are as follows: (1) the direct seeding of inter-seedling and supplementary seedlings should be carried out according to the plant spacing of 4-5 cm when the seedling height is 5-7 cm, and the supplementary seedlings should be transplanted with soil and watered after planting.

(2) weeding and weeding should be carried out in time after each harvest. (3) topdressing combined with ploughing and weeding, topdressing 2000 kg of human and animal manure water per mu.

Soil preparation and fertilization

Select a good plot, per 667m2 spread rotten barnyard manure 2000 kg, ploughing depth 15 cm, and ploughing with ploughing, each 667m2 spread ammonium dihydrogen phosphate, urea 50 kg. Rake fine and flat, making a border 1.2m wide.

Seedling raising and transplanting

In the whole border, sow the seeds according to 1215g / m2, soak the seeds in 60 ℃ water for 24 hours, fish them out and dry them a little, mix them with fine sand (fine sieve) according to the ratio of 1: 100, and then sprinkle them evenly into the border. Cover the grass grass or agricultural film, spray water once a day, keep it moist, and germinate and germinate in 15-20 days. After the seedling comes out, remove the mulch, spray water immediately, and then spray water once every 3-4 days. The seedlings were transplanted to the field when the seedling height was 5 cm, with a row spacing of 20 cm and 1 plant per hole.

Daejeon live broadcast

In order to germinate all the seeds of direct seeding, it is best to choose to plant them in overcast and rainy days. The time is from September to early October, strip broadcast or hole sowing. Strip sowing is ditched according to the row spacing of 25cm and 30cm, the ditch depth is about 4cm, and the hole spacing is about 30cm. When sowing, spread the seeds evenly in the ditch and cover with 0.5 cm thick loose fine soil fertilizer or plant ash. It can also be covered with agricultural film or grass to keep the soil moist. Remove the mulch from the whole seedling and do a good job in seedling management.

Field management

Ploughing, weeding and topdressing. After seedling emergence, when the seedling height is 1cm to 2cm, thin human feces and urine water is applied once combined with weeding, and 1000 kg is applied as seedling fertilizer every 667m2. When the height of the seedling is 4cm and 5cm, carry on the interseedling and replenish the seedling, and finally fix the seedling according to the plant spacing of 3cm, and make up the missing seedling at the same time. After the seedlings were fixed, the water of human feces and urine was applied once respectively. In the future, there should be no weeds in the field, and topdressing should be applied once after each harvest to promote the germination of new branches and leaves. After the last harvest in November, winter manure was applied again, 200 kg of rotten barnyard manure, 25 kg of cake fertilizer or calcium superphosphate per 667 square meters, and then ditched between rows after composting. After application, cover the soil and cultivate the soil to keep warm and prevent cold.

Irrigation and drainage. Always keep the soil moist and not short of water in the seedling stage. It should be irrigated in time in the dry season. In the rainy season and after each flood, ditch drainage should be carried out in time to prevent stagnant water from flooding roots and seedlings.

Pest control

Rust: mainly damaged leaves, the leaves of the damaged plants showed yellowish-brown spots on the back, and in severe cases, the leaves turned yellow and fell off. Prevention and treatment: at the initial stage of the disease, you can use 97% rust sodium 300 times 400 times (with a small amount of washing powder), or spray with Baume 0.2-0.3 degree stone-sulfur mixture every 7-10 days, 2 times in a row.

Epidemic disease: it is easy to occur in high temperature and rainy season, showing waterlogged dark spots on the leaves, and then wilting and drooping. Control method: spray 1 ∶ 1 ∶ 120 Bordeaux solution or dimethazone 800 times solution in the evening.

Insect pests: there are mainly aphids, African mole crickets, Spodoptera litura, etc., which can be sprayed with 1000 times of 40% dimethoate EC or 1000 times of 50% phosphoramine EC. Aphids and vegetable black insects are easy to occur during flowering, the former can be controlled by dimethoate, and the latter can be sprayed with 1000 times of dichlorvos.

4. Pest control: Scutellaria barbata has almost no disease in the process of growth, and aphids and vegetable black insects are easy to occur during flowering. The former can be controlled by dimethoate, and the latter can be sprayed with 50% dichlorvos 1000 times.

5. Seed retention technique from May to June, when the seeds are gradually mature, the fruit branches are harvested in batches, dried in the sun or shaded, rubbed out the seeds, winnowed the stems and impurities, placed in cloth bags and stored in dry places. The continuous cropping field of Scutellaria barbata does not need to leave seeds, and the roots and seedlings can be renewed for 3-4 years.
