Family planting and hydroponic culture of tulips

Tulips are bulbous flowers planted in autumn and blooming in spring. They like cool and are afraid of heat. Under natural conditions, about 10℃ underground 15 cm in autumn is the most suitable for planting, because this temperature is suitable for root growth, this temperature is about "November" in North China, and in the middle and lower reaches of the Yangtze River in late October to early November. Good root development before winter is crucial for good growth in the following spring. In winter, the seed bulb planted in the low temperature for further development, through the long winter low temperature, break dormancy, germination in early spring, with the temperature rise, leaf flowering.

Tulips usually planted at home are imported bulbs bought from the flower market, which are generally treated at low temperature, usually treated at 5 ° C or 9 ° C for 2 to 3 months, commonly known as "5 ° C balls" and "9 ° C balls", which can be planted directly. Potted soil available fertile sandy loam, stripped before the ball hard brown skin, conducive to root growth. The seed ball is buried in two thirds of the soil and placed in an environment of 7℃ to 10℃. This temperature is conducive to the formation of roots and is not conducive to the growth of buds and the propagation of pathogens. If the temperature is lower, the root formation is slow, and the stem and leaf growth is delayed; if the temperature is high, the stem and leaf growth is early before the root formation, and it is easy to produce blind flower phenomenon, that is, only flower buds are grown without flowering. Rooting stage, without light, can be put into a carton, placed in a closed balcony at a temperature of about 9℃. After the root system is formed, it can be moved to indoor lighting to promote the growth and flowering of stems and leaves. If the room temperature exceeds 20 ° C, the light is weak, and it is easy to grow, it is more suitable at 15 ° C to 20 ° C, usually about 1 month can bloom, which depends on the variety planted. If the purchased seed ball has not been treated with low temperature, it should be planted according to the method of seed ball without low temperature treatment. After potted in autumn, the flowerpot can be buried outdoors and covered with soil for 10 cm. Generally, the flowerpot can be taken out in January and cultured indoors. It can bloom in about January. Tulip growth and flowering, the nutrients it needs mainly come from the bulb, the formation of the bulb is more dependent on the nutrients in the soil, so in order to get strong flowers and large plants, the quality of the bulb is also very important. Generally speaking, the ball circumference greater than 10 cm is of high quality, which is to pay attention to when purchasing the ball, of course, there is no damage at the root plate is also to pay attention to when selecting the ball. Potted tulips, flowers can be timely topdressing, promote its growth, promote the formation of new seed balls.

Tulip hydroponics, is also based on the growth habits of tulips. Because hydroponic tulips are disposable seed balls, it is more important to purchase high-quality seed balls, and the seed balls purchased must be treated at low temperatures. Water is filled in a vase or other container, the seed ball is put into the mouth of the container, half of the seed ball is immersed in water, and then the hydroponic container is placed in an environment of 7 DEG C to 10 DEG C to promote rooting. After the root system is formed, it takes about 15 to 20 days to move to an indoor lighting place. Due to the rapid consumption of water in the rooting stage, the lack of water should be checked every 2 to 3 days, and the water should be replenished in time to prevent the roots from drying due to water loss. If the seed ball is small, it can also be supplemented with some nutrient solution, which can be used with 0.15 grams of nitrogen, phosphorus and potassium compound fertilizer per liter plus the same amount of calcium nitrate. If there is no calcium nitrate, only compound fertilizer can also be used. In the hydroponic stage, half of the water or nutrient solution can be replaced every 3 to 4 days. If the water solution is completely renewed at one time, the roots are easy to grow slender and not strong.
