Last Updated: 2024/11/22, 1. Seedling preparation (1) nursery bed selection. Choose the land with fertile soil, adequate water source, good drainage, convenient transportation, easy to build shade, gentle slope and leeward. (2) Seedling bed finishing. The seedbed is 1.2 meters wide and 5 centimeters high, the length depends on the topography, and the bed groove is about 40 centimeters wide. Cover the top layer of the seedbed with 5cm thick fine laterite (aseptic soil), spray it with water, and then flatten it with a plank. (3) build a shade shed. Choose 70% or 50% sunshade net, the height of the shed is 1.6-2 meters, and one is planted every 2-3 meters.

1. Seedling preparation (1) nursery bed selection. Choose the land with fertile soil, adequate water source, good drainage, convenient transportation, easy to build shade, gentle slope and leeward. (2) Seedling bed finishing. The seedbed is 1.2 meters wide and 5 centimeters high, the length depends on the topography, and the bed groove is about 40 centimeters wide. Cover the top layer of the seedbed with 5cm thick fine laterite (aseptic soil), spray it with water, and then flatten it with a plank. (3) build a shade shed. Choose 70% or 50% of the sunshade net, the shed is 1.6-2 meters high, plant a pile every 2-3 meters, and set up the sunshade net. A shade must be built before the seedlings are planted. Hairy grass and mountain white grass can also be used to build a shade shed. 2. Raising seedlings (1) choose the disease-resistant branches of Yunnan Yunhang No. 10 tea as seedlings, each bud as a plant, leave a 3.5 cm long stem on the lower part of the leaf surface, cut into a 30-degree slope at the leaf surface, and leave half or 3 of the leaves. The upper part of the stem on the leaf surface can be 0.5 ml 1 cm long. Soak the base of cuttings 2-3 cm in a mixture of 5 grams of quick-acting Shenggenling and 100 grams of water for 5-10 seconds. See figures l and 2. (2) cutting seedlings. Plant spacing 2 cm, row spacing 5 cm, hold the bottom of the bud with thumb and index finger, leaves facing outward, cutting one by one, the cutting depth should be thumb and index finger close to the seedling bed, and the leaf surface must be upward. As shown in figure 3. (3) cutting season: the best cutting season is from August to October, and the seedling shed can be out from May to June of the next year. 3. Management of cutting seedlings (1) watering. Keep the soil moist. General cutting within 60 days, look at the seedbed humidity spray, press the seedbed with your fingers, if you get up the nest, you can not spray water, if you can not get up the nest, you must spray water, requiring the seedbed not to crack. (2) the new buds issued within 30 days after cutting must be erased so as not to affect the rooting of the base. (3) spraying pesticide and fertilizing. After cutting, the liquid was sprayed with dimethoate or methamidophos at a concentration of 500 times. The cuttings of clones will still produce new roots in about 60 days, so it is necessary to spray 500 times diluted urea in 60-70 days, and then spray urea 2-3 times a month. In the future, pay attention to observe the seedling situation, with the seedling to determine water, fertilizer and medicine.
