How to plant lupin: lupin can be planted by sowing or cutting

Lupinus Lupinus, also known as lubing flower, is a perennial herbaceous ornamental flower. It has rich colors, such as white, pink, light blue, rose red, yellow and so on, and has a long flowering period. It can be used for piece planting or group planting in banded flower beds. It is also a good material for cut flower production. Do you know the planting method of lupin? Let's get to know about it!

How to plant lupin lupin growth habits: Lupin is more resistant to cold (- 5 ℃), likes cool climate, sunny place, avoid hot, slightly resistant to shade, needs fertile, well drained sandy soil, developed taproots, few fibrous roots, not resistant to transplantation. Developed root system, drought resistance, the most suitable for sandy soil, the use of phosphate insoluble phosphorus ability is also strong. It can still grow in rainy and waterlogged areas and acid soil where other plants are difficult to grow; But if often in calcareous soil or poor drainage place cause poor growth. It can endure the temperature of 0 ℃, but it will freeze to death when the temperature is lower than - 4 ℃; Summer heat also inhibited growth.

How to plant lupin lupin planting methods: there are two kinds of lupin planting, namely sowing and cutting.

Sowing propagation was carried out in autumn, and the seeds germinated orderly at 21-30 ℃. In the production of Lupinus Lupinus, sowing is mostly in spring and autumn, and spring sowing in March. However, the postnatal period of spring sowing is in summer. Affected by high temperature and heat, some varieties will not blossom or the proportion of flowering plants is low, the flower spike is short, and the ornamental effect is poor.

Under natural conditions, autumn sowing blooms earlier and grows better than spring sowing. Sowing in the middle of September to October, and flowering in the next April to June. 72 hole or 128 hole plug can be seeded and covered. The seedling soil should be loose and even, breathable and water retaining, and the special seedling soil or peat soil and perlite should be mixed.

Lupin seeds are large, common or coated, about 40 seeds / g. The suitable temperature for germination is about 25 ℃ and the medium is moist. The seeds germinate in 7-10 days and the germination rate is high( I've done some personal experiments. Before planting, it's better to mix the seeds with sand and rub them together. Because the seeds are hard and hard, they are not easy to sprout. After grinding, they can break the soil quickly and come out.)

Cutting propagation: cut the sprouting branches from the rhizome in spring, cut them into 8-10cm, and it's better to take some rhizomes and cut them in cold bed. In hot and rainy areas in summer, Lupinus Lupinus often can not survive the summer and die, so it can be cultivated as a biennial. It should be planted in the cultivation site in early spring, with plant spacing of 40cm, early planting, early growth, early flowering and seed setting.

The above ground parts withered after fruiting before summer, and new plants germinated in autumn, or seeds were collected before withering. North China needs to be protected for the winter.
