Planting non -sex tea trees are the road to success in the development of tea in the world

Throughout the tea producers in the world, in order to seek the development of the tea industry, they attach great importance to the selection and popularization of tea trees. However, on the road of seed selection, countries have taken a detours, that is, the selection of sexual species to be hindered to the road of non -sex selection.

India: In 1780, tea seeds were collected from China to start planting tea. Later, it was discovered that the Assam variable tea trees were immediately collected. The tea seeds were immediately collected to establish a seed garden to promote the excellent local varieties in Assam's variants. But the Assam varieties are group species, and they are still a mixed group after breeding with seeds. After recognizing that the asexual reproduction is an effective way to improve varieties, it shifted from the practice of building a seedlings to improve varieties to asexual selection (selection of single system systems). The area accounts for more than 80%of the total area of ​​tea gardens.

Indonesia: Located in tropical, tea can be collected all year round, and unique natural conditions provide superior conditions for good breed breeding. In the late 1960s, it introduced short -sized cutting technology from my country, and a single plant selection in adult tea gardens, selected plants with large buds and strong disease resistance, and cultivated PS1, K8, CIN148 and other varieties to expand new tea gardens and new tea gardens and new tea gardens and Rebuild the old tea garden.

Kenya: In the 1960s, it began to promote non -sexual varieties, and it has achieved good species. The country's Tea Research Institute and major tea companies are engaged in selection and cutting seedlings in good breeds and cutting seedlings. The Institute adopted a single plant selection method and promoted a large number of non -non -non -non -non -non -native varieties. These varieties are based on thick buds, dense germination, large picking surface, strong regeneration after picking Standard selection. Each tea company also uses a single plant selection method to breed, such as the selected non-sexual species P-13 output is doubled than that of sexual groups. Good breed reproduction is generally adopted with short -cutting of nutritional bowls, which improves the garden out of the seedlings and the survival rate of transplantation. Kenya is an emerging tea -producing country. Due to the cultivation of non -quality and good varieties, with superior natural conditions and advanced tea -making technology, the country's CTC black tea quality ranks the crown of similar black tea in the world.

Japan: After recognizing that the quality of tea -making tea made of leaflets is low, a set of tea tree breeding system is established, which improves the efficiency of selection and promotion of good breeds. By 1986, 37 planting varieties were promoted. Japanese tea tree breeding lacks resources, so it pays great attention to collecting resources. There are as many as 7,500 tea tree resources collected from my country and India. In the selection method, a single plant is separated and breeded, focusing on planting early, middle, and late -born varieties. Cutting reproduction uses a plastic shading mesh and spray device, cutting cuttings with two -leaf leaf, cutting cuttings in June of that year, and giving out of the garden in March of the second year. This long spike cutting seedlings have a higher survival rate and growing rapidly.
