How to fertilize lily to make it grow super well?

Lily was originally a short-day plant growing in the forests and grasses of southwest and northwest Shan Ye, so most varieties like cool and humid semi-shady environment and are more hardy. It grows in fertile sandy soil rich in humus and well-drained soil, with developed bulbs and bright colors. Lilium lancifolium likes warm and dry climate conditions and is more resistant to sunlight. Lily is suitable for nitrogen fertilizer, and bean cake, vegetable cake, farm compost and NPK compound fertilizer are the best. During the growth period of lily, it is necessary to loosen the soil and weed regularly, and combine watering and fertilization for intertillage. Generally, dilute fertilizer is applied 2-3 times in the growth period to promote the growth and development of its plants and seedlings. Apply 1-2 times of phosphorus and potassium fertilizer when the bud is close to flowering to ensure that the seedlings have sufficient nutrition in the bud stage and flowering stage, which can not only make the flowers huge and bright, but also promote the development of bulbs. When planting in a large area, attention should be paid to ventilation and proper shade. If planted or potted in a small area, for ornamental varieties with many branches and thin flowers, brackets should be set to prevent the flowers from breaking. Although there are few diseases and insect pests in lily, we should also pay attention to prevention and control.

When planting lilies, the north should choose a sunny place to avoid the wind, and the south can plant them in a slightly shady place. The suitable planting time is August-September. Apply sufficient base fertilizer one month before planting and dig deep into the soil. Compost and plant ash can be used as base fertilizer. Planting should be deep (generally 3-4 times the diameter of the bulb) to facilitate the rhizome to absorb nutrients. If the planting in the north is too shallow, it will be vulnerable to freezing injury in winter, which will affect the growth of roots and bulbs. It is not suitable for intertillage and weeding during the growing period, so as not to damage the rhizome. If possible, sprinkle some sawdust on the planting ground to cover the soil. This can not only prevent weeds from growing, but also preserve moisture and reduce soil moisture, which is beneficial to bulb development.

Potting should be carried out in September-65438+10. Culture soil should be mixed with humus soil, sandy soil and garden soil at the ratio of 65,438+0: 65,438+0: 65,438+0, and the bottom of the basin should be fully decomposed with compost and a small amount of bone meal as base fertilizer. The planting depth is generally about 2-3 times of the bulb diameter. Lily doesn't have high requirements for fertilizer, so it is more suitable to apply fertilizer in the early spring growth and early flowering. Some foreign growers think that lily needs nitrogen and potassium fertilizer, and it should be applied every 10- 15 days during the growth period, but the supply of phosphorus fertilizer should be limited, because too much phosphorus fertilizer will cause the leaves to turn yellow. Phosphate fertilizer can be applied at flowering stage for 1-2 days. In order to enrich bulbs, residual flowers should be cut off in time after flowering to reduce nutrient consumption. Water only needs to keep the soil moist, but it should be watered frequently in peak season and dry weather, and water should be sprayed frequently around the flowerpot to improve the air humidity. Pot soil should not be too wet, otherwise bulbs will rot easily. Potted lilies should be replaced with new culture soil and base fertilizer once a year. In addition, flowerpots should be rotated once a week during the growing period. Otherwise, plants tend to grow tall and affect their appearance.

Lily (scientific name: Lilium), also known as Qiangqu, Fanjiu, Shandan and Daoxian, is a perennial herbaceous bulbous plant of Liliaceae, which is native to China and mainly distributed in temperate regions of the northern hemisphere such as East Asia, Europe and North America. More than 0/00 species of/kloc have been found in the world, of which 55 species are from China. In recent years, many new varieties have been produced through artificial hybridization, such as Asian lily, musk lily, perfume lily, fire lily and lily.

Lily is known as "Shang Yun Fairy". Because of its elegant and pure appearance, Catholicism regards lily as a symbol of Maria, while Vatican and France regard lily as a national flower. Lily's seed head is composed of scales, which means "harmony for a hundred years" and "all the best". China has regarded it as an essential auspicious flower for weddings since ancient times.

morphological character

Perennial bulbous herbaceous flowers, plant height 40-60 cm, some as high as 1 m. The stem is erect, unbranched, grass-green, with red or purple-brown spots at the base of the stem. There are bulbs under the ground, which are wide oval or lanceolate, white or yellowish, and the fleshy scales with a diameter of 6-8 cm are huddled together, and there is a membrane outside. Most fibrous roots are born at the base of the ball. Simple leaves, alternate, narrowly linear, petiole-free, directly attached to the stem, with parallel veins. Some varieties produce purple or green granular beads between leaf axils, and their beads can be propagated into small plants. Flowers are inserted at the top of stem, which are racemes, clustered or solitary, with large corolla, long tube, funnel-shaped trumpet, and sepals divided into six parts. Because of the slender stems and large flowers, they often droop or stretch horizontally when they are open. Colors vary from species to species, mostly yellow, white, pink, orange-red, some with purple or black spots, and a flower with many colors is very beautiful. Petals are flat and rolled outward, so they have the reputation of "rolling Dan" and some flowers are fragrant, so they are called "musk lily". Flowers fall and bear long oval capsules.
