Key points for the conservation of commercial flower tulips

Tulips are more and more widely used in commodities, and more and more flower growers grow tulips. Tulips are a relatively delicate flower species. If you want to grow tulips well, you must pay attention to scientific planting methods.

Prepare the matrix. To prepare a high-quality matrix, it is required to retain water and breathable, not too high salinity, not too sour, ph value should not be less than 6, no diseases and insect pests and harmful substances. The bulb should be firmly planted in a cultivation bed deep enough (at least 5 cm deep). In recent years, we used the mixture of peat, mature soil and sand with 1 ∶ 1 ∶ 1 as cultivation medium, and the effect was better. About half a month before planting, mature farm manure was applied to the bed soil as base fertilizer, and appropriate amount of carbofuran and carbendazim were added (or covered with 1% formalin for disinfection), fully irrigated, and carefully ploughed and raked before planting to ensure that the soil was loose.

Planting. Due to the high temperature in the greenhouse, tulips will occur late vernalization, and will reduce the effect of low temperature treatment to promote cultivation. Therefore, it is better to plant early than late, about two months before the Spring Festival, about the first and middle of November. Remove the brown bulb before planting and soak in 50% carbendazim 500 times solution for about two hours. The row spacing of the plant is 9 × 10 cm, and the top of the bulb is flat or slightly lower than the soil surface at the time of planting. Proper shallow planting can lead to early flowering. Sometimes the tulip bulb can bloom more than 5 days earlier when it is exposed to the soil surface. After planting, it was watered thoroughly to promote its rooting.

Cultivation and management temperature. A week later, the seed ball began to sprout. In the pre-seedling and seedling stage, keep the indoor temperature at 12-15 degrees Celsius during the day. If the temperature is too high, it should be ventilated and cooled in time, not less than 6 degrees Celsius at night, so as to promote early rooting, strong roots and strong seedlings. If the temperature is too high at this time, the plant stem will be weak and the flower quality will be poor. After more than 20 days, when the plant has grown two leaves, it should be warmed up in time to promote the bud to break away from the bracts in time. The indoor temperature should be kept at 18-25 degrees Celsius during the day and above 10 degrees Celsius at night. After more than 20 days, the Corolla began to color. The first branch flowers bloomed from late December to early January, and it took 10 to 15 days for them to bloom. At this time, they should be placed in batches according to the time needed. The higher the temperature, the earlier the flowers bloom. After the Corolla is fully colored, the plant should be placed at 10 degrees Celsius for sale.

Tulip

Choose 10 cm to 20 cm flowerpot, pad 3 cm thick charcoal slag, masonry grain, ceramsite and so on as drainage layer, add loose and fertile neutral soil. Pay attention to the use of new soil, planted lily plants and bulbous flowers of the old soil can not be used to prevent viruses, nematodes and other infections. The top of the seed ball is flush with the soil surface, put in the shade for 3 to 5 days, pour through the water and put it in a cool outdoor place. The surface of the basin soil should be watered when it is dry below 1 cm.

From December to February of the following year: in the cold season, the flowerpot can be wrapped with styrofoam and placed outside in the leeward and sunny place, and the root system can grow above 5 ℃. If the basin soil is not dry or watered, it will be watered thoroughly.

March to April: March sprouting; 15 ℃ to 18 ℃ is the peak period of stem and leaf growth, which should be maintained in the sun. 1 ‰ all-element compound fertilizer is poured once a week. The leaf surface can be sprayed with warm water once or twice a day. After the bud appears, often sprinkle water to the ground around the potted flowers to increase the humidity of the air.

What is the cultivation method of tulips? what are the main points of tulip farming? many families like to raise some flowers and plants at home, which not only decorate the home space and make the mood better, but more importantly, it can purify the indoor air, such as hanging orchids, tulips and so on. So, how to raise tulips? What is the cultivation method of tulips? Today, the editor of the provincial many decoration network will introduce the main points of tulip culture, hoping to help you all. The cultivation method of tulip 1. Soil tulip requires both water retention and air permeability, the salinity should not be too high, and the pH value should not be less than 6. The mixture of peat, mature soil and sand with 1 ∶ 1 ∶ 1 as cultivation medium has a better effect. The cultivation method of tulip 2. Sufficient sunlight is necessary for the growth of tulip. Insufficient sunlight will cause poor plant growth, cause bud drop, plant weakening, lighter leaf color and shorter flowering period. But tulips on the pot after more than half a month, should be properly shaded, in order to facilitate the growth of new roots. In addition, during germination, the elongation of flower buds is inhibited by light. Shading can promote the elongation of flower buds and prevent the early vegetative growth from growing too fast. After emergence, light should be increased to promote plant jointing, form buds and promote coloring. After the buds are fully colored in the later stage, direct sunlight should be prevented and the flowering time should be prolonged. Culture methods of tulips 3. Temperature

Tulips prefer warm winters and cool summers, and the optimum temperature for growth is 9-13 ℃. Strong cold resistance, can withstand the low temperature of-35 ℃ in winter.

4. The cultivation method of tulip should be watered thoroughly after watering and planting, so that the soil and seed bulbs can be fully combined and beneficial to rooting, and the water should be properly controlled after budding. When the leaves gradually elongate, water can be sprayed on the leaf surface to increase air humidity. Sufficient water supply should be ensured at bolting stage and budding stage to promote the full development of flowers and proper water control after flowering. The cultivation method of tulip 5. Fertilizing tulip does not require high fertilizer. If the growth is weak, you can apply some nitrogen fertilizer. When the root system is well developed, 2 kg of calcium nitrate is applied every 100 square meters, spread in three times, each time at an interval of more than one week. Culture methods of tulips 6. Insect pests

The pathogens of tulip diseases and insect pests can be carried by the seed ball or by the soil, which mostly occur in the environment of high temperature and high humidity. the main diseases are stem rot, soft rot, broken color disease, quenching disease, blind bud and so on. Adequate soil disinfection should be carried out before planting, virus-free bulbs should be selected as far as possible, diseased plants should be dug up and destroyed in time, and fungicides should be poured once or twice in the growth process of the greenhouse, the effect is better; good ventilation should be maintained to prevent high temperature and humidity; when aphids occur, 3% natural pyrethrum can be sprayed 800 times.
