The growth habit of white lupine, the cultivation technique of lupine

1. Growth habitsLupins are 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, and are not resistant 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, it can often cause poor growth in calcareous soils or poorly drained places.

Can tolerate air temperatures of 0, but freezes to death when temperatures are below -4; The extreme summer heat also inhibits growth. <>

2. Sowing seasonSowing and propagation is carried out in autumn, germinating neatly under the high temperature of 21-30 The sowing method of lupine is very simple, it can be sown directly, the seeds should be evenly sprinkled, each acre of land needs about two or three catties of seeds, the amount of seeds is not much, after sowing, the soil is covered with water and gently compacted, 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.

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.
