Jasmine planting technology

Jasmine is an ophiopachicaceae, jasmine, alias tea flowers, etc., evergreen shrub flowers, in the north with potted plants. Leaves opposite, oval or oval, shiny, white flowers, single-valve, single-pole aroma, double-fold. Three to nine cymules are formed from May to October in the flowering period from July to August in summer. Ecological habits originating in India and other places, sex hi warm and humid climate, hi light, not cold, fear of drought but afraid of cockroaches. Hi is rich in humus, fertile and well-drained slightly acidic soil. The optimum temperature for growth is 15°C to 25°C, and the room temperature in winter should be kept above 5°C. Propagation methods are usually propagated using cutting methods. From March to May, select 1 to 2 years of strong shoots. The length of the cuttings should be between 10 cm and 15 cm. Take the upper 2 to 3 leaves and insert them into a clean river sand covered with a plastic film. Half shade, often spray moisturizing, about one month to take root. There are many layers in the summer, rooting from 10 days to 20 days, then you can cut off the mother plant in the fall of the year and plant it separately. The ramets are usually combined with the douche, and the ramets should be cut after the ramets to ensure the survival rate. Cultivation points 1. Choose suitable culture soil: pot soil can use 4 parts of peasant soil, 4 parts of compost soil, 2 parts of river sand, and add some cake fat or decomposed chicken, duck and duck manure as basic fertilizer. For good drainage, the pelvic floor can be more Some drainage (such as gravel, tiles, ceramsite, etc.). 2. Timely change basins: When changing pots, moderate amount of pruning should be performed on the roots. 3. Water and fertilizer should be appropriate: jasmine is afraid of drought and taboo, therefore, the amount of watering should depend on the season, plant growth and other conditions. From April to May, permeable for 2 days to 3 days. Jasmine flowering season in summer should be more watering, sooner or later, in addition to the normal watering should be sprayed to the foliage and the ground to reduce the temperature and increase air humidity. Autumn and winter should control the amount of water. Due to the long flowering period, the amount of fertilizer needed is also large. It is possible to chase some manure and fertilizer water every half month. The flower bud differentiation and flowering stage should be increased by applying phosphorus and potassium fertilizers to increase the concentration of flowers. After autumn, they should be applied less or stop fertilizing, which is beneficial to overwintering. Sometimes the jasmine grown by the family, only long leaves do not bloom, mainly due to excessive nitrogen fertilizer, lack of sunlight, then more phosphorus and potassium fertilizer should be applied to increase the illuminance. 4. Pruning: In spring, pruning and reshaping were performed on the pots, and thin and thin branches were removed. Each pair of leaves was left with 4 pairs of leaves to be shortened to facilitate growth, pregnancy budding, and flowering. After heavy flowering, it is necessary to carry out a heavy cutting to promote new shoots and make the plants grow robustly. When each batch of flower buds grows to the size of mung bean, it is dehydrated when there is a bud, and the leaves and buds are deprived of water. When drooping, just water it so that the flowers can gather and the inflorescences look good. The common pests and diseases include red spiders and aphids, especially in the spring, and the yellow leaves often become white and gradually fall off. Homes can be sprayed with tobacco leaves or smoked tobacco smoke, which can not only play a role in killing insects, but also ensure indoor sanitation.
