Three propagation methods of Gardenia jasminoides

The reproduction of Gardenia jasminoides can be divided into sexual reproduction and asexual reproduction, while sexual reproduction generally refers to sowing methods, and asexual reproduction is divided into cutting method and striping method. As the seeds of Gardenia jasminoides are not easy to collect, cuttings and striping are generally used for propagation.

Gardenia

First, sowing and reproduction

Generally choose full, dark red ripe fruit, even shell sun or dry as a seed, before sowing, use scissors to cut the seed pericarp, dig out the seed, rub in hot water to disperse, remove floating seeds or impurities, and then remove the sunken full seed, spread it on the bamboo mat, put it in a ventilated place to dry too much moisture. Generally choose Xiangyang hillside or Tufang, the soil layer is deep, loose and fertile sandy loam sowing, you can use the field edge corner planting, or interplanting with legumes. Ploughing the land 1.5 feet before planting, remove miscellaneous trees, set up the border according to the width of 4 meters 5 feet (the soil quality is better, the distance can be larger, otherwise smaller), the border height is 6 inches, and you can apply soil and miscellaneous fertilizer, green manure or human and animal manure as base fertilizer, for example, 20 kilograms of human dung and urine per mu, shallow rake the soil after the soil is dry, and level the border surface. Sow the seed ditch on the border surface according to the row spacing of 6 mi / 7 inch, and the ditch depth is about 1 inch to be sown.

Gardenia can be sowed in spring or autumn, generally in spring, spring sowing before and after Rain Water, autumn sowing before and after the Autumn Equinox, seeds mixed with fire ash evenly sown in the sowing ditch, and then cover the flat sowing ditch with fine soil or fiery soil, cover grass with water, often keep the soil moist, in order to facilitate seedling emergence, with seeds 4 Mu 6 jin per mu. After emergence, we should pay attention to remove the cover grass in time, weed frequently in the seedling stage, be careful not to hurt the roots of the seedlings, need to dilute human feces and urine after weeding, and can be transplanted after raising seedlings for one year. If the transportation is far away, it is appropriate to use yellow mud slurry root, cover grass to moisturize, plant one plant in each hole, cover soil, compaction, and sprinkle water. After planting, weeding and topdressing is applied once every spring and summer, which can be applied to human and animal manure, barnyard manure, compost, cake fertilizer and so on. Before flowering in summer, it is better to apply fertilizer with more phosphorus and potassium content, and fertilization is generally carried out after weeding and loosening the soil.

2. Cutting propagation

It can be divided into spring planting and autumn planting. Spring planting is carried out in the middle and late February, and autumn insertion is carried out from late September to late October. There is a slight difference between the north and the south, but the survival rate is the highest between summer and autumn. Cuttings choose healthy 2-3-year-old branches, cut 10 Mel 12 cm, cut off the lower leaves, the top two leaves can be retained and cut off half, first dipped in the vitamin B12 injection, and then obliquely inserted in the bed, leaving only one section above, pay attention to shade and maintain a certain humidity.

Generally, it can take root in 1 month, and it can take about 15 days under the condition of 80% relative humidity and 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. In the south, there are also those who are propagated by water insertion, that is, cuttings are inserted on a disc woven with Reed stalks and let them float on the surface of the water, so that their lower parts take root in the water, and then transplanted and cultivated.

3. Strip pressing method

It is generally carried out before and after the Qingming Festival in April or in the Meiyu season. In April, one-year-old strong branches are selected from the 3-year-old mother plant, which are 25cm long and 30cm long. They are pulled to the ground, and the buried parts of the branches are scratched. If they can be dipped in 200ppm powder acetic acid and then covered with soil compaction, it is easier to take root. If there are trigeminal branches, you can get three seedlings at the fork at a time. Generally, it can take root after 20-30 days, can be separated from the mother plant after rooting in June, and can be planted separately with soil or a single plant in the next spring. Spring is the best way to transplant seedlings or potted plants, and it is necessary to bring soil balls in the rainy season. Keep the soil moist during the growing period, and water more during flowering and midsummer. Fertilize once a month and increase phosphorus and potassium fertilizer before flowering. Pruning and shaping in the early spring of the following year, and cut off dead branches and long branches in time.

The cultivation method of Gardenia jasminoides points for attention in cultivating Gardenia jasminoides

Jasmine is a famous flower far and near, and jasmine is sung all over the world. There are many varieties of jasmine, one of which is called gardenia, which has high breeding value and ornamental value. Let's take a look at the breeding methods and matters needing attention of gardenia.

Culture methods and matters needing attention of Gardenia jasminoides

I. the culture method of gardenia-- light

Gardenia especially like the sun, that is, even in the hot season, humid growth environment can promote the cultivation of gardenia. Gardenia likes the sun very much and can't resist the severe cold, so it leads to a href=' https://z.xiziwang.net/tea/' target='_blank' > tea attendant Lai Mei shallow @  choose W  plaque  neon cyanide boy enthusiastically seek E  to get rid of 4 graceful tanning shallow V plaque  Wei Zi Yue  enthusiastically, fat fan Tan Yan an, Mu Yin Jian  ú ⒉ call Ligularia  slippery worms? / span >

2. the culture method of gardenia flower-- water

Gardenia can occasionally resist drought but avoid stagnant water. If you plant gardenia in summer, you can water them twice in one day and add some water spray treatment. Once into the winter, gardenia will begin to enter the sleep period, this time does not need more watering, otherwise there will be too much water.

3. The cultivation method of gardenia-soil

The growth of Gardenia needs sufficient soil nutrients, and the soil can balance the pH value of soil by adding some humus and micro-acid substances, which is beneficial to the growth of Gardenia jasminoides.

How to cultivate Gardenia jasminoides

The fragrance of gardenia is particularly refreshing. The evergreen gardenia in the four seasons will be in full bloom in summer, when the fragrance is all over the street. Gardenia is very easy to feed, representing the beautiful gardenia. What should you pay attention to if you want to grow gardenia? Let's take a look at the culture methods of gardenia.

Culture method of Gardenia jasminoides

I. the cultivation method of Gardenia jasminoides-environment

Gardenia likes warm, moist and well-lit growth environment, and it can be semi-shaded properly when conserving gardenia. at the same time, if it encounters strong light, then gardenia will be hurt.

2. Soil, the culture method of gardenia.

Gardenia loves acidic soil, which makes gardenia grow healthier and more beautiful. Before planting gardenia, the ph value of the soil should be controlled between 4 and 6, and the soil should take into account the loose and fertile soil.

Third, the culture method of gardenia-- temperature.

Gardenia growth temperature should be about 20 degrees, winter should be maintained at about 10 degrees, less than 10 degrees of this environment will cause gardenia is not too high and too short. If it is hot in summer, choose a ventilated place to place.

Fourth, the culture method of gardenia-- water.

Gardenia likes to be moist and needs a lot of water to support the growth of the whole plant. The next time you water it, you have to wait until the soil is dry and white. In summer, it is necessary to spray water on the leaves to make the leaves and flowers wetter.
