A detailed introduction of gardenia culture methods

In the flowers, gardenia is undoubtedly one of the more familiar flowers, people like to breed at home, but many people do not know much about gardenia breeding methods, resulting in a lot of problems in the breeding process, such as yellowing leaves, not blooming and so on. Today, let's take a detailed look at the detailed introduction of gardenia culture methods.

Culture method of Gardenia jasminoides

First, sour soil culture, gardenia need scattered light, so like sour soil, if the soil is alkaline, it will make gardenia can not absorb iron very well, which has a great impact on the formation of chlorophyll, and further cause flower branches to wither and even die; so the soil must use loose, fertile acid soil, you can also add some substances with such effect.

Second, put in a cool place, gardenia must not be exposed to the scorching sun, otherwise the leaves will be withered and yellow, but it does not mean that it should be put in the whole shade, because it has a certain demand for light, it is best to keep 60% of the light every day, in addition, after entering April, fertilizing should be carried out twice a month.

Third, the air humidity, gardenia like to be wet, so the air can not be too dry, according to expert statistics, if the air humidity is less than 70%, it will affect the normal opening of flowers, but if it is too wet, it will cause rotting roots and yellow leaves, so in addition to normal watering, we should often spray clean water nearby. Another problem we should pay great attention to is that water should not be watered too much, otherwise it will also affect growth. So how to water gardenia?

A, when you see the soil is dry, knock on the flowerpot with your hand. If there is an empty sound, it needs watering. The bottom of the flowerpot starts to leak and stops. It is better to add some eggs and soy milk to the watering water, which is more conducive to growth.

Fourth, fertilization tips, gardenia like fertilizer, but can not add too much fertilizer at one time, must be thin fertilizer, must not save trouble, otherwise it will cause thick branches, big leaves, thick green, it will lose its own appreciation effect.

Fifth, temperature requirements, the growth temperature of gardenia can not be too low, because it likes temperature, generally speaking, the temperature of the growing period is 18 to 22 degrees, 5 to 10 degrees in winter, and frostbite if it is less than 10 degrees below zero, which should be paid special attention to in the north.

Sixth, proper pruning, gardenia is very easy to grow luxuriant branches, and cause airtight and disorganized feeling, which will cause nutrition dispersion and poor ornamental, so it is necessary to prune it, it is best to choose three main branches when pruning, and cut off the roots and tillers to sprout new branches at any time, and the branches should be truncated in time after the flowers are shedding, so that new branches will sprout under the cut. When the new branch grows three nodes, it is necessary to pick the heart so as not to grow blindly.

Seventh, disease prevention, we usually see four kinds of gardenia diseases:

A, iron deficiency, which is the most common, iron deficiency will cause the formation of chlorophyll, and then make the leaves lose green, when you can use ferrous sulfate water and low concentration of black alum water, three times a month.

B, magnesium deficiency will lead to yellow veins of the lower old leaves of Gardenia jasminoides, so it is necessary to spray with low concentration of magnesium sulfate solution.

C, the soil is too wet or too dry, this can be seen in the third point

D, the sun exposure, this can refer to the second point.

Eighth, breeding methods, Gardenia jasminoides generally have two methods of reproduction: cutting and striping.

In the rainy season, the twigs are 15 centimeters long and inserted into the seedbed to take root in 12 days.

B, in April, the biennial branches were selected, which were long 2O-25 rice, buried in the soil and kept moist, about 30 natural roots, separated from the mother plant in summer, and planted in the next spring.

Breeding methods of Gardenia jasminoides

1. Cuttage propagation

The north is in the greenhouse from October to November, and the south can be inserted from April to the Beginning of Autumn at any time, but the survival rate is the highest between summer and autumn. Cuttings choose healthy 2-year-old branches with a length of 10-12 cm, cut off the lower leaves, cut the lower end into a 45-degree angle, tie them into small bundles every 20 to 30, soak the slant in 0.05% rooting powder solution or 0.05% naphthalene acetic acid solution for 15 seconds, take out the drying solution and insert it into the sand. According to the row spacing 20~25cm, plant spacing 7~8cm, insert the cuttings bevel into the soil. Compacted and watered, set up a low shade shed for shade.

It can take root in about 15 days under the condition of 80% relative humidity and the temperature of 20-24 ℃. It is better to soak in indole butyric acid of-6 power of 20-10 to-6 power of 50-10 for 24 hours. When the rooting seedlings begin to grow, they can be transplanted or put on the pot for a single plant, and can blossom after 2 years. The north can also be propagated by water insertion, that is, the base of the cuttings is soaked in clean water, the water is changed once a day, and the water holder can grow new roots in a semi-shaded place for about 20 days. Weeding and topdressing should be strengthened (see seed breeding). After 1-2 years of cultivation, it can be transplanted when the seedling height is 40~50cm. This method can not only obtain a large number of seedlings, but also blossom and bear fruit earlier, and maintain the good characters of the female parent.

2. Striping propagation

In April, strong branches were selected from 3-year-old mother plants, which were 25 to 30 meters long for striping. If there were trigeminal branches, three seedlings could be obtained at the fork at one time. Generally, it can take root after 20-30 days, can be separated from the mother plant in June, and can be planted separately or single plant in the next spring.

3. Sowing and reproduction

Most of them are carried out in spring, and the seeds germinate slowly, germinate about 1 year after sowing and blossom after 3-4 years, but it is not easy to receive seeds in the northern pot.

1) seed selection: select plump, crimson ripe fruits, dried or dried in shells. Before sowing, cut the pericarp of the seeds with scissors, dig out the seeds, rub them in hot water, remove floating seeds or impurities, then fish out the sunken full seeds, spread them on the bamboo mat, put them in a ventilated place to dry too much moisture, and then sow the seeds.

2) Land selection and preparation: select the deep, loose and fertile sandy loam, plough 1-1.5 feet, start the border according to the width of 4-5 feet, the border height is 6 inches, apply 20-30 piculs of human feces per mu, wait for the soil to dry, shallow rake mud blocks, flatten the border surface. Sowing ditch is opened according to 6-7 inch row spacing on the border surface, and the ditch depth is about 1 inch to be sown.

3) sowing seedlings: spring sowing or autumn sowing, spring sowing before and after Rain Water, autumn sowing before and after the Autumn Equinox, sowing seeds mixed with fire ash evenly in the sowing ditch, and then covering the sowing ditch with fine soil or fiery soil, covering the grass with water, often keep the soil moist, in order to facilitate seedling emergence, 4-6 jin of seeds per mu.

Seedling management: after sowing, often watering to keep the border moist, about 20 days after emergence, remove the cover grass from the border, and then strengthen the management. When the seedlings grow 2-3 true leaves, the seedlings are thinned, the seedlings are too dense and weak, and when the seedlings grow 5 true leaves, the seedlings are kept according to the seedling distance 5~8cm, and frequently ploughed and weeded to maintain the growth of weeds in the seedling land. At the same time, proper topdressing should be carried out in the first year, once in spring, summer and autumn in the second year, and once in spring, summer, autumn and winter in spring, summer, autumn and winter. Combined with ploughing and weeding, 1000~1500kg was applied to human and animal manure every time per mu. From autumn sowing to the end of autumn and early winter in the second year, the seedlings can be planted when the seedling height is above 30cm, and the seedlings sown in spring can be planted when the seedlings reach 30cm in the next spring. If they do not reach the 30cm height, they will continue to be cultivated until the end of autumn and the beginning of winter. A large number of seedlings can be obtained by this method.

4) many seedlings often grow around the rhizosphere of Gardenia jasminoides. Every year in early spring or late autumn and early winter, the strong-growing plants are selected, the topsoil around them are planed, and the seedlings are cut off from the mother roots with a knife to be planted as seedlings.

4. Water inserting and rooting

The annual branches with a length of 10 to 12 meters and 2 leaves were taken. Cut the tip of the branch into a horseear and soak it in 0.1% potassium permanganate solution for 4 hours, then take it out and insert it into clean water. The length of the cuttings is the total length of the cuttings. The brown bottle is used as a container to change the water every 1 to 2 days. The cuttings can also be drilled in the wood or foam board to insert the cuttings into the holes and then float on the water.

After the new root is grown, it can be transplanted to pot or ground when it is moved from dark to bright, when the root length reaches 1.5-2 cm, and the number of roots per plant is 6-7.

Maintenance and Management of Gardenia Flower Culture method

Gardenia is a woody plant, evergreen, blooming around the Dragon Boat Festival every year, with white flowers, dense silk flowers and fragrant flowers. It is an excellent plant for urban beautification, highway greening and garden bonsai. Gardenia cultivation time is short, the investment is low and the benefit is high. It is planted in the first year, transplanted in the second year, and sold in the third year. The market price of each plant is about 2 yuan, and the large one can be sold for more than 3 yuan. An annual income of more than 10,000 yuan per mu is a good way to get rich.

1. Gardenia is suitable for growth in acidic soil. Like wet and afraid of dry, the humidity can be 40%, 70%, can grow. If the potted plant is not watered for 10 days, it will die from drought. Like fertilizer, you can often apply water containing ferrous sulfate, alum fertilizer or corrosive fertilizer. It is resistant to high temperature and can grow even at 40 ℃. It is resistant to severe cold and will not freeze to death even if it is about 10 ℃.

Gardenia cultivation method Gardenia jasminoides belongs to flowering and sterile plants, there are no seeds, only by cutting cultivation.

1. Cut in time. The first half of the year is in April and the second half is from August to September. These two periods are not only the best season for planting gardenia, but also the best time for gardenia to multiply. The temperature is generally between 15 ℃ and 35 min, and the climate is mild, so it is suitable for the growth of cuttings. Generally, it will take 40 days for rooting and sprouting.

2. Land preparation.

Choose the site for ①. To choose a more convenient watering land, to ensure that there is a source of watering.

② prepares the ground. To choose the land with fertile, loose soil and good ventilation effect. Generally, the soil can be improved by turning the soil deeply before frost and through overwintering frost. Sprinkle some plant ash and sand before cutting, turn the ground over about 30 centimeters, then water it, and you can insert it.

2. Striping propagation

In April, strong branches were selected from 3-year-old mother plants, which were 25 to 30 meters long for striping.
