What are the key points of cultivation techniques for lupine?

1. Sowing methodThe sowing method of lupine is very simple, it can be sown directly, to spread the seeds evenly, each mu needs about two or three catties of seeds, the amount of seeds is not much, after sowing, cover the soil and water it and gently compact, so that the seeds can better absorb water and nutrients, and the seedlings can emerge in about a week. The management of it in the later stage is also very simple, ensure sufficient water and fertilizer, and do a good job in the prevention and control of pests and diseases.

2. Flowering periodThe flowering period of lupine is 3 to 5 months, can bloom for about three months, its flower type and color are very beautiful, the shape is unique, the color is bright and charming, and it has a strong ornamental value. Lupine is often used to create a variety of flower landscapes, is a commonly used flower variety in landscaping, a variety of scenic spots, parks and other places, especially suitable for making flowers, can give people a different sense of beauty, make people shine, now very popular with people, planting range is gradually expanding. <>

Lupin, also known as lupin, is a plant of the legume family Lupin, native to western North America. The plant is a perennial herb with racemes apical, spire-shaped, and rich and gorgeous flower colors. Lupins prefer cool, sunny environments.

It does not like heat and is slightly shade-tolerant. Prefers fertile, loose, well-drained acidic sandy loam soils.

1) Sowing. It can be sown in spring and autumn, but it is sown in autumn and in good condition, and it will bloom in the next year. The seedling substrate is preferably mixed with peat, perlite. Suitable temperature for germination25 . Keep the substrate moist and germinate in 7-10 days.

2) Transplant seedlings. Lupine seedlings last about one month, and they can be transplanted and planted after the true leaves. Retaining the original soil when transplanting seedlings can promote the slowing of seedlings. Before planting, 1 2 times of repotting can be carried out according to the growth situation. Because lupins have straight roots, it is best to choose high bucket pots for planting pots.

3) Matrix. PH in as well. Substrate pH plays an important role in the normal growth and flowering of lupin.

The application of sulfur powder in the cultivation medium can play a regulating role. Since it takes some time for sulfur powder to decompose in the matrix to play a regulating role, it should be applied as soon as possible.

4) Temperature. The minimum temperature should not be lower than 5 to avoid frost damage to the leaves. Lupins like coolness, so pay attention to cooling protection during the summer high temperature season.

5) Lighting. Prefer full sun, but avoid direct sunlight, sun burn is easy to cause yellowing of leaves, plant growth dwarf. Therefore, lupins are suitable for planting under trees in forests, in cool and ventilated places.

6) Pests and diseases.

The more common is leaf spot, which is brown to black in color, and in severe cases, it can cause the leaves to die. It can be sprayed with carbendazim wettable powder 1500 times.

Lupine is a perennial herb that can reach up to 60 cm in height. The stem is branched at the base, palmately compound leaves, leaflets lanceolate to inverted-lanceolate, the leaves are thick, the racemes are apical, the inflorescence axis is slender, the peduncle is very short, the calyx is bilabial, the corolla is blue, and the flag and keel petals are white markings. The pods are oblong and linear, and the seeds are ovate, flattened, marked, and smooth.

It blooms from March to May and bears fruit from April to July.

It is native to North America and grows mostly in temperate regions of sandy lands. There are many varieties of horticultural cultivation.

Lupine is commonly known as Lubing flower, the inflorescence is straight, fruitful, the flower color is bright and colorful, there are white, red, blue, purple and other changes, and the flowering period is long, it can be used for piece planting or planting in the ribbon flower bed group, and it is also a good material for the production of cut flowers. Lupins, more hardy (- 5 or more), prefer cool, sunny places, avoid heat, slightly shade tolerant, need fertile, well-drained sandy soil, developed taproots, few fibrous roots, not tolerant to transplantation. The root system is well developed, drought tolerant, most suitable for sandy soils, and the ability to utilize insoluble phosphorus in phosphate is also strong.

It can still grow in rainy, waterlogged-prone areas and on acidic soils where it is difficult for plants to grow; However, poor growth is often caused by calcareous soils or poor drainage. Can tolerate air temperatures of 0, but freezes to death when temperatures are below -4; The extreme summer heat also inhibits growth. Hengjing flower seedlings

The flower language of lupine: maternal love, fantasy and bitterness. Lupine dialect, also known as Lu Binghua, tea farmers in Taiwan Province of China, when planting tea, especially the unique alpine cloud tea in Taiwan Province, in many cases need to plant some "Lu Binghua" around the tea mountain or even near the tea tree.

The reason is that this plant can help the healthy and smooth growth of tea leaves, and play a role in making tea fragrant and sweet.

1.Soil: Lupin has a deep root system, few nodules, requires a deep soil layer, good drainage, acidic sandy loam, and poor plant growth in neutral and slightly alkaline soils.

2.Split planting: Lupin seedlings last 30-35 days. After the true leaves are fully open, the seedlings are transplanted and planted separately. When transplanting seedlings, the original soil is retained, which is conducive to slowing down the seedlings.

3.Temperature: Lupin is cultivated in autumn or, and should be protected from cold during wintering. The temperature should be above 5 to prevent the leaves from being frozen, which will affect the early vegetative growth and appreciation.

4.Fertilization: Lupine begins to top dressing in March, and generally chases 20% water-soluble fertilizer once a week. When you look good, you can chase it once every half a month until the arrow stops.

5.Repotting: In lupine breeding, one or two repots should be changed according to the growth situation, and the pots should be high to meet the growth needs of the main root system and determine a reasonable cultivation density.

6.Pests and diseases: Lupins are prone to leaf spot, powdery mildew, rust, base rot, etc.

In the process of cultivating. When the disease is mild, the diseased leaves should be cleaned up in time. At the beginning of the disease, spraying fungicides every 7 to 10 days, and spraying 2 or 3 times in a row can control the occurrence and spread of the disease.

Lupin, also known as lupin, belongs to the genus Legume Rupin and is native to the Mediterranean region. Butterfly, blue-purple. In horticulture, there are also white, red, green and other colors that are cultivated, as well as large hybrid flowers with many color variations.

Lupins are sown in the spring in March, but grow after the summer after the spring sowing. Due to the influence of high temperature and heat, some varieties may not bloom or have a low proportion of flowering plants, short panicles, and poor ornamental effect. Flowering period:

Autumn sowing in mid-September flowering is earlier than spring sowing, and the growth is good, sowing is sown from mid-September to October, and flowering is from April to June of the following year. 72-well or 128-well tray for seeding and mulching. The seedling soil should be loose, uniform, breathable and water-retaining, and it is best to use special seedling soil or peat soil and perlite.

The seeds are large, plain or coated, about 40 grams. The optimal germination temperature is about 25 and the medium is moist. The seeds are unearthed, germinate in 7-10 days, and the germination rate is high.

Lupin's whispering language is bitter. The flowering period is from March to May, and the fruiting period is from April to July. After the real leaves are opened, the seedlings are transplanted and planted, and the original soil is preserved when the seedlings are moved, so as to facilitate the slow seedlings.

The flower language of lupine is motherly love, fantasy, and bitterness. When planting, it is necessary to grasp the seasonal changes, and the flowering period is generally from July to August.
