Soilless cultivation methods and techniques of Flowers

Flower soilless cultivation is a new kind of plant cultivation technology in modern times, which can intensively produce a large number of vegetables and fresh cut flowers in a small area, which can not only shorten the production cycle, but also greatly improve the product quality. make the size of flowers, melons and fruits.

Today, with the three-dimensional development of urban housing, soilless cultivation is especially suitable for the use of sporadic areas such as windowsill, balcony, hall, desk and so on. The method of soilless cultivation is used to raise flowers. It can put an end to the occurrence of underground diseases and insect pests, and it will not give off the stench caused by fertilizing the potted soil, and there is no need to prepare the cultivated soil, thus saving the trouble of loosening the soil, weeding and turning the pot to change the soil. More importantly, the nutrient loss of growing flowers in potted soil is as high as 40%-60%. On the other hand, the nutrient loss of soilless cultivation will not exceed 10%. If cultivated properly, the growth of flowers is stronger than that of potted soil.

Some family flower growers in southern China often soak the stems of rich bamboo without roots in a vase. They can take root in about 10 days and grow well, and they don't have to plant them in pot soil after taking root. Other flowers and plants, such as bamboo evergreen, can be cultivated and furnished in this way, which is called "hydroponic culture".

People believe that soilless cultivation is hydroponic flower culture, but it is not. Hydroponic culture is only a method in soilless culture. in addition to single-culm foliage flowers such as Fugui bamboo and bamboo evergreen, many other foliage and flowering flowers with strong or no stalk must first be fixed and let them grow upward without lodging, which means that the roots must be fixed with granular cultivation media sold in florists or bean stone, perlite and so on. And then inject water into people for cultivation. Gravel culture, sand grain culture, bdelloid right culture, asbestos block culture, plastic particle culture and so on are commonly used, which are collectively referred to as soilless cultivation.

When soilless cultivation is carried out in the flower field, the nutrient solution is self-prepared according to the different needs of all kinds of flowers, which is quite complicated to operate, and many problems are involved. such as the composition of nutrient cable, the concentration of nutrient solution, the effect of nutrient composition, the consumption and supplement of nutrient elements, and the test of pH and so on. When family flower growers carry out soilless cultivation, they do not have the conditions and need to prepare their own nutrient solution. Professional authors have designed and made a lot of nutrient solutions for family flower cultivation to be sold in the florist. You should read the instructions carefully when using them. The key is that the water halo should not be less than the water dilution indicated on the instructions, otherwise the root system will be burned due to excessive concentration.

Cultivation skills and matters needing attention of hyacinth

According to the editor of Huinong net, hyacinth likes cold bulb flowers, cold and not heat-resistant, there are many colors and varieties, the flower is full of fragrance, winter and spring is its flowering season, has the habit of summer dormancy, the normal flowering period is from January to March. It is a kind of flower that is easy to cultivate. Here are the cultivation skills and matters needing attention of hyacinth arranged by Huinong net. Friends who love flowers, take a look!

Cultivation skills of hyacinth:

Reflowering ability: strong (but the effect of reflowering is not good).

Planting difficulty: easy (suitable for hydroponic culture, potted plant and ground planting).

Depth of soil cover: the corm is shallowly buried, and the soil covers 2/3 of the bulb.

Planting temperature: the highest temperature in the daytime is stable at 10-15 ℃, which is beneficial to the rooting of the bulb. Natural flowering: hyacinth blossoms around March in spring and usually blossoms about 120 days after planting. Flowering is affected by temperature and light sooner or later.

Seed ball treatment: after getting the hyacinth seed ball, remove the miscellaneous roots at the bottom of the root plate and soak it in diluted carbendazim solution for 30 minutes, which has achieved the effect of disinfection and sterilization. After soaking, it is removed and placed in a cool and ventilated place to dry naturally, waiting for planting.

Ball up: before treatment; ball down: after treatment, carbendazim is soaked for 30 minutes and then dried naturally.

Warm Tip: some people are allergic to hyacinth and will itch after contact with hyacinth seed ball, so it is recommended that we wear gloves to clean the seed ball. If your hands are itchy, don't panic, wash your hands with soap and you'll be all right after a while.

Soil culture methods:

Pot selection: 10 cm diameter flowerpot species 1 ball, 17 cm diameter flowerpot species 2-3 balls.

Select soil: choose fertile, well-drained nutritious soil for cultivation, avoid too wet or sticky soil.

Upper basin: the sphere is shallowly buried, exposing the sphere 1 stroke 3.

Watering: after cultivation, water thoroughly and leave it in a cool place to wait for germination.

Hydroponic culture method:

Water level requirements: prepare a hydroponic container, hold water, the water level is about 5mm distance from the seed ball chassis, do not let the seed ball directly touch the water surface or even soak in the water.

Dark treatment: put the bottle in a dark and ventilated place, or cover the transparent container with a black plastic bag or light shield (it is good for the bulb to take root in the dark) and change the water every 2 to 3 days. Rooting time: the fast one can take root in a week, and the slow one can take root in about 2-4 weeks. After sprouting, the water bottle can be moved to a sunny place. If there is less water, it will be increased, and the water level still cannot be soaked to the seed ball.

Matters needing attention in daily maintenance

1. Turn the basin. Hyacinth flower pole phototaxis is strong, indoor potted plant single light source maintenance, need to turn the basin once a day, so that hyacinth receive light evenly, so as to prevent the flower rod from growing upside down.

2. Mildew. If the cultivation is not well ventilated and the humidity is too high, the seed ball is prone to mildew spots, as long as the seed ball does not serve soft rot, there is no need to worry. Hydroponic bulbs can be used to wipe moldy parts to keep ventilation and water clean; soil bulbs can be diluted with carbendazim and irrigated.

3. Clip the arrow. The arrow clip is the phenomenon that the flower stem can not stretch normally and is caught by the leaves, forming a "shrinking neck" phenomenon. The main reason is the excessive temperature at the time of flowering. It is generally appropriate for hyacinth to bloom at 15-20 ℃. If hyacinth is found to have a tendency to entrap arrows, the potted flowers can be moved to a warm dark place for maintenance to delay the flowering time of plants.

4. Compound flowers. Hyacinth compound flowering is poor, the next year flowering sparse, ornamental effect is not good. If you want hyacinth to compound flower, you can add some slow-release fertilizer to the soil for the first time as base fertilizer, cut off the flower stem after flowering, do not cut the leaves, at the same time, water normally, supplement liquid fertilizer, stop water and fertilizer until the leaves are completely withered and yellow, there is no need to pilling, and then restore water and fertilizer when sprouting in autumn.

Hyacinth cultivation is very simple, but blooming is not suitable for flowers, is a very suitable for lazy people to raise flowers, the above are hyacinth cultivation skills and points for attention, usually more busy guys can consider cultivation!
