Fertilization method of Tulip
Tulips are perennial bulbous flowers of the lily family. Plant height 30-40 cm, bulb ovoid, outer coat squamous-membranous leaf. Color has bright red, black red, yellow, white, purple and other colors. Like warm and humid, sunny or semi-shady environment, not resistant to heat. Requirements humus-rich, good drainage sandy loam.
1) Family farming. They are often used to breed. After rooting and leaf-pulling, topdressing is generally carried out, and fertilization is carried out once every half month. Phosphorus and potassium fertilizer are mainly used, and appropriate amount of golden baby bacterial fertilizer is added, which can make the flower flavor more fragrant.
2. Production in shed. Tulips need a lot of nutrition in germination and bud stage. Tulips used for cut flower production are more sensitive to fertilizer. If the fertilizer is insufficient, the stem and leaf growth is weak, and the flower stem is weak. After rooting, apply some nitrogen fertilizer appropriately, apply 2 kg of calcium nitrate per 100 square meters for 3 times, every two times for one week. Calcium ions in calcium nitrate can also prevent tulip catault. K, N and proper proportion of Gymboree bacterial fertilizer should be applied when bulbs sprout to 2 - 3cm high. When the bud is formed, apply potassium fertilizer again, or spray potassium dihydrogen phosphate on the leaves to facilitate the flowering of tulips.

Family planting and hydroponic culture of tulips
Tulips are bulb flowers planted in autumn and blooming in spring. They like to be cool and afraid of heat. Under natural conditions, it is most suitable to plant about 10 ℃ at 15 cm underground in autumn, because this temperature is suitable for root growth, which is around "National Day" in North China and from late October to early November in the middle and lower reaches of the Yangtze River. Before the arrival of cold winter, good root development is very important for the good growth of the following spring. In winter, the planted bulbs develop further at low temperatures, through a long period of time.
