Method for efficiently cultivating ornamental lupin in protected area

Abstract

The invention discloses a method for efficiently cultivating ornamental lupine in a protected area. The inventive method adopts the method of cultivating ornamental lupine in a protected area. The seeds are germinated and treated at low temperature, seedlings are raised and planted in nutrient soil, and finished flowers are cultivated in combination with fertilization and light and temperature control. The main steps are: (1) Build a steel pipe greenhouse; (2) After the seeds are germinated at a constant temperature of 20°C±2°C, they are treated at a low temperature of 3°C±2°C for 45-60 days; (3) Use peat soil: chaff ash: leech Stone = 1:1:0.5 seedlings, select I level seedlings with more than 3 leaves; (4) Use vegetable garden soil: coal ash: river sand = 6:3:1 for planting; (5) Apply urea, cake fertilizer and compound fertilizer to promote growth , Spray KH2PO4 to promote flower bud differentiation, supplement light for 4 hours a day, and keep the shed temperature at 20-28°C; (6) Change pots for sale. Adopting the method of the invention to cultivate finished ornamental lupine flowers can significantly improve the germination rate of seeds, the preservation rate of seedlings, shorten the seedling cultivation cycle, promote flowering and improve the uniformity of flowering, and solve the technical problem of cultivating finished ornamental lupine flowers.

Description

technical field [0001] The invention relates to a high-efficiency cultivation method for ornamental lupine protected land, belonging to the technical field of flower cultivation. Background technique [0002] Lupine ( Lupins polyphyllus Lindl) belongs to the Fabaceae Papilionaceae Lupine genus of one-year to perennial herbaceous plants, commonly known as Lupine flowers. Lupine has large and colorful flowers, compact and beautiful plant type, and high ornamental value. It is a new type of garden and flower bed flower newly introduced in my country that enjoys both flowers and leaves. Lupine symbolizes maternal love and happiness. It is known as the mother's flower in China. It has a wide range of uses and a broad market prospect. The introduction and cultivation of lupine has enriched the members of the huge flower family in my country, added materials for landscaping, and also added elements for family flower arrangements, which has high economic, ecological and socia...

AI Technical Summary

Problems solved by technology

Limited to the ecological characteristics of lupine growth and immature cultivation techniques, open-field cultivation in my country's subtropical monsoon climate type areas, the temperature in autumn is high, the germination rate and preservation rate of sowing seedlings are low; the duration of low temperature in winter is short, and the consistency of flowering is poor; spring rainfall High water content, too much water attached to the leaves will affect the compact plant type, which is easy to cause diseases, and also affect the flowering quality, reducing the ornamental quality
