Perfume grass, also known as Yang Jasmine. Rich green leaf color, thick wrinkles. The flowers are small, gathered into a puffy ball, and are in ochre or purple, with a special tempting aroma that makes people feel relaxed and happy. The temperature is suitable for flowering throughout the year, but flowering is the best from April to June. Flowers containing aromatic oils can be extracted for the production of floral cosmetics.
1, breeding methods
Generally, they are propagated by cuttings, but they can also be propagated by sowing. However, if they are cultivated in a greenhouse, it is usually difficult to obtain seeds.
The appropriate cutting period can be carried out in all seasons, but the spring and autumn seasons are better; the indoor cuttings are mostly carried out in February and March, with tender shoot cuttings. Generally during the rainy season, stem segments with 2 to 4 nodes are cut from strong shoots growing on the upper part of the plant. The cuts are required to be about 0.5 cm below the nodes and smooth. The lower blades of the cuttings were removed and only the upper 2 to 3 pieces were left. River sand is usually used as a cutting medium. The depth of cuttings is 1/3 of the cuttings. After inserting, gently press around the base to make the cuttings and sand closely connected. After inserting, pour enough water and shading. After maintaining a certain humidity, the roots may be rooted for about 3 weeks, and then transplanted first. To small pots, basin soil can use humus, sand, garden soil, add a small amount of plant ash and mix well. After 20 days, the pots were planted in larger pots. When the seedling grows 7~8 cm tall, it will be picked up. Strengthen the management of fertilizer and water, which generally takes about 60 days from cuttings to flowering.
The suitable autumn time for sowing is autumn sowing. The life span of perfume grass is very short and can only be maintained for one year. Therefore, the seeds harvested should be sown early so as to obtain higher seedling emergence rate. The temperature is 22°C and the germination takes about 20-30 days.
2. Cultivation Management
Potted soils should be well-drained, fertile and loamy soils, generally using 4 parts of garden soil, 3 parts of compost soil, 2 parts of sandy soil and 1 part of plant ash. It usually takes 2-3 months from seedlings to flowering. The roots of plants are well-developed, and the growth of fibrous roots is very prosperous. Therefore, it is advisable to change the basin 1-2 times in order to develop the root system.
After transplanting on the basin. To start the seeding from the seedlings in a timely manner, promote its branching and more flowering. Those who need to turn vines should also be taken care of to make it a dense and complete plant. If larger plant types are to be cultivated, they can be supported and supported by stanchions and stripped of all their lateral buds to allow the shoots to grow in height. After the stems grow taller, they repeatedly pick their hearts and grow into an umbrella-shaped plant.
Perfume grass moist environment, strong spring season, pots and soils should be kept moist, too dry and too wet will cause the leaves to yellow, generally spring and autumn watered once a day, summer growth is slow, it is best to be poured every morning and evening 1 Secondary water. In winter, the water should not be over-moist and the water can be poured in 3 to 4 days.
Perfume is a happy flower and it can be top-dressed one week later. During the growth period, a thin, decomposed cake, or fermented chicken manure is applied once a week. A compound fertilizer is applied once every two to three weeks. Winter season is low and hot in summer. You can extend the interval between topdressing or stop fertilizing.
Perfume grasses are hi-light plants that require plenty of sunlight. In a daylight-deficient environment, they tend to grow thin and thin, have small branches and can not flower. In winter, move it to a sunny place. In the summer, place the perfume grass in the shade or in a shaded area to cover away the strong sunlight. Otherwise, the leaves can easily burn and dry yellow; the spring and autumn seasons can make perfume Get enough sunshine.
When the summer temperature exceeds 30°C, the plants grow slowly into a semi-dormant state. If the sun exposure is exposed to the sun, the leaves tend to brown. Therefore, in summer, the pots should be moved to a cool and ventilated place. The optimum growth temperature is 15°C～25°C. In winter, the room temperature can be kept above 13°C to continue flowering. The greenhouse can bloom in all seasons. The overwintering temperature is 5— 7 °C, the temperature dropped to 0 °C or so, that is, frost damage.
After several years of cultivation, the plants are susceptible to aging, and the flowering parts are constantly moved upward. The base leaves gradually fall off with the lignification of the stems, often appearing in the lower part of the plant. Therefore, cuttings are generally used after 2 to 3 years of cultivation. Separately cultivate new plants. Perfume grass is a sub-shrub, but due to its soft branches, old plants are scattered, the posture is not beautiful, and it is often cultivated for one or two years. During the growth process, it is easily harmed by scale insects. Attention should be paid to prevention and control.
