1. Seed breeding 1. Seed production: Collect mature fruits from August to September each year. 2, seed treatment: (1) smashed, rinse the peel, fishing sinking full of seeds, dry shade and then net, will have purebred. (2) Break the dormancy of Kuding tea seeds. Kudingcha belongs to physiological after-ripening, generally adopts the wet sand stratification method, and also can use variable temperature treatment or chemical treatment with different concentrations to break the dormancy. 3, nursery, transplant seedlings, seedling management and the same routine. 4. Planting season: It is generally planted from November to February of the following year. 5, planting specifications: to take a highly dense dwarf technical measures, plant spacing of 2 meters * 1.5-1.8 meters, pit specifications 100 * 80 * 70 cm. Second, asexual reproduction Generally there are three methods of cutting, cutting, and grafting. After many tests and practices have proved that regardless of the type of propagation method, the survival rate of Kuding tea is more than 80%, and it is only widely used in the local area. More convenient cutting propagation for a brief introduction: 1, renovation plug and inserting soil. The width of the bed is 100 cm wide, about 30 cm high, and the length is convenient for work. The composition and proportion of inlaid soils are based on vermiculite powder: river sand: fire soil=3:5:2. 2. Preparation for cuttings. (1) The cuttings are preferably young trees, and the fine branches that were either lignified or semi-lignified are selected. (2) Pruning of cuttings. The length of the cuttings, generally about 4 cm, at least 2-3 axillary buds (latent buds) per section, cutting, cutting leaves, 1/2 or the whole leaf on the top of the cutting (the number of cutting leaves, should see the cuttings Size to determine, in order to facilitate photosynthesis is appropriate) the lower end of the incision close to the base of the axillary bud or internodes, and cross-cut into a vertical cross-section, the cut surface is small, healing fast. 3, plant hormone treatment. Kudingcha is a hard-to-root tree species. The treatment of plant hormones directly affects the growth and survival rate of roots. The ABT1 rooting powder is commonly used in the country, and the effect is ideal. Firstly, according to the maturity of cuttings, the mother liquor is diluted to the required concentration, which is generally as follows: cutting rate of 500-1000-2000 PPM, processing time of several seconds to 30 seconds, slow cutting concentration of 50-100-200PPM, soaking time 0.5 hours - 1 hour - 2 hours. 4, cutting. Select rainy days or evening, with the leaves not overlapping, insert the cuttings straight into the substrate. The depth is 2/3 of the total cutting length. Short cuttings should not be shallow. 5, management after cutting: (1) moisturizing, we must always keep the bed moist, when the sun is hot, spray 5-6 times a day. (2) Shade is preferable to the use of shade nets on the market. (3) After transplanting and cutting for 2-3 months, the axillary buds begin to sprout 3-4 mm, which proves that the cuttings have taken root, continue to be cultivated and cultivated for a period of time, and the new roots grow to 1-2 cm in size, which can be transplanted into the nutrition film bags. When the seedlings are 26-30 cm in height, they can get tea plantations. China Agricultural Network Editor
