According to the characteristics of the petals at the time of flowering, jasmine is divided into three categories: single-jam jasmine, double-jasmine jasmine and double-jad. There are several types of jasmine varieties: Single jasmine: The plant is short, 70-90 cm high, with thin stems and vines, so it is called "vine jasmine". The leaves are elliptical, the leaves are thin, the tips of the leaves are slightly pointed, and the entire edges are 5 to 9 cm long and 3.5 to 5.5 cm wide. Corolla single layer, lobes (petals) less, 7 to 11 pieces, each piece about 1.3 cm long, 1 cm wide, oval, white, slightly wrinkled surface, slightly pointed at the top, so it is also called pointed jasmine. The single-flowered jasmine corolla tube is longer, about 1.5 cm, and has 2 stamens, which are as long as the pistil. Gathering inflorescences, terminal or axillary, each flower inflorescence 3 to 12 flowers, more than 30 more. The flower buds are slightly pointed, small and light. China's single-jam jasmine has been cultivated for many years and has formed many local fine varieties. The high yield and good quality include Fujian Changle, Fuzhou, Jinhua and Taiwan. Among them, Taiwan jasmine is fresher, fresher and purer. The single-flowered jasmine flower buds open early, and the flowers are generally open at 6 to 7 in the evening. Each hundred flowers are heavy, and the flowers are 22 to 25 grams, which is lighter than the double-jad jasmine. The jasmine tea made from single-jawed jasmine has a strong aroma and a refreshing taste, which is beyond the reach of double-jasmine jasmine. Single-jasmine jasmine is more drought-tolerant and suitable for planting on foothills and hilly slopes, but the yield is less than that of double-jasmine jasmine. It yields 150-200 kg per 0.067 hectares, and the height is not more than 400 kg. It is not cold-resistant and resistant to cockroaches. Resistance to pests and diseases is weak. Double-flowered jasmine: Double-flowered jasmine is the main species cultivated in large areas in China. The plant is 1 to 1.5 meters high and is an erect shrub with many branches, stems and branches, and ash-brown wrinkles on the base of the stem. Young stems are green, robust branches with ribs and short hairs. Leaves opposite, broadly ovate, entire, reticular, leafy green, leafy thick and lustrous. Cymes, terminal or axillary, each flower inflorescence 3 to 17 flower buds, more than 30 more. The flower bud is oval, with a flat or slightly pointed top, also known as a flat jasmine. Double-flowered jasmine is usually of better quality with a pointed tip. The flowers are more plump than the single-jad jasmine and have a slightly lower water content. The corolla tube is slightly shorter than a single jasmine and is about 1 cm long. Corolla lobes (ie, petals) are more, 13 to 18 pieces, and the base is covered with tiling to form two layers, 4 to 8 inner layers and 7 to 10 outer layers. The petals are about 1.1 cm long and about 1 cm wide. 2 stamens, 1 pistil. The flowers are white and pure, the wax is obvious, the flowers are strong, and the spit is slower and slower. The opening time of the flower bud is about 2 hours later than that of the single-flowered jasmine. The flower is usually open at 8 to 9:00 in the evening, and the natural spit can be delayed for more than ten hours. Each hundred flowers are heavy, about 23 grams of spring flowers, about 30 grams of flowers, and about 26 grams of autumn flowers. The aroma of scented tea with double-jawed jasmine is strong and strong, although it is not as fresh and pure as single-flowered jasmine tea, but the double-jam jasmine branches are tough and strong, resistant to stress, cold-resistant, moisture-resistant, easy to cultivate, high yield per unit area, currently The main planting in China is double-jad jasmine. Planted in Hengxian County, Guangxi, can be harvested in the same year, the yield of flowers per 0.067 hectares can reach 150-200 kg, the output of every 0.067 hectares in 3 years is about 500 kg, and the average yield per 0.067 hectares can reach 800-1000 kg for more than 5 years. The highest production can reach more than 1500 kg. Multi-petal jasmine: Multi-petal jasmine branches have obvious ridges. The leaves are thick green, the buds are tightly knotted, round and short, and the top is slightly notched. The corolla lobes (petals) are small and thick, and are particularly numerous, generally 16 to 21 pieces, and the bases are arranged in a tiling shape to form 3 to 4 layers, and the layers are distinct when opened. Stamens 2 to 3 pieces. The multi-petal jasmine flower is mostly open at 7-8 in the evening, mostly opening 1 to 2 layers, and the other day is finished. There are also those that are not open and faded. The opening time of the multi-flowered jasmine is long, the aroma is lighter, and the yield is less. The flowers used as the scented tea are not ideal. However, it has strong drought tolerance and is robust in hillside dryland. If it is crossed (or grafted) with excellent single or double jasmine varieties, it is likely to obtain new varieties of jasmine with strong resistance, good quality and high yield. (New Jasmine).
