Toon temperature is suitable for cultivation in areas with an average temperature of 8-10°C, and the cold resistance can be increased with the addition of seedlings. Annual seedlings seeded with seeds may be frozen at around 10°C. The camphor tree is hi light, more moisture-resistant and suitable for good health in the wet and moist soil around the riverside and yard. Generally, sandy loam is preferred. Suitable soil pH is pH 5.5-8.0. The management method of citrons is as follows: 1, the type of selection. Generally selected mainly red camphor. 2, cultivation seedlings. It is advisable to raise the seedlings in arch shelters and greenhouses. The average sowing volume is 2-3 kilograms, and 10-12 thousand grains per kilogram. However, the seed germination rate of Toona sinensis is relatively low. Sowing with warm water at 25-30°C for 12 hours is required before seeding. After soaking seeds, they are mixed with fine sand and then sowed directly onto the seedbed. The seedbed should be selected in areas with high topography, loose fertility, and good irrigation and drainage conditions. Fertilizer should be given in sufficient amounts and a layer of straw should be added after sowing in order to facilitate watering. Fertilizers are mainly organic fertilizers, and it is advisable to farm in March-April. 3, seedling management. (1) Germination period. Seed emergence after germination takes 7-10 days and 15-20 days for seed sowing. During tillage and emergence, the soil should maintain a certain degree of humidity and water once every 1-2 days. The daily temperature is 25°C and the nighttime temperature is not lower than 8°C. (2) Wheat seedling stage: The seedlings are 6-7 cm high with 2-3 true leaves poured with 1 water and weeding with loose soil. The roots of the seedlings are 0.5 cm thick and are sprayed with 100-200 times liquid urea and sprayed with clear water. Pouring seedlings. Seedlings have 4-5 true leaves, a height of about 10 cm, and seedlings, Dingmiao seedlings, transplanting seedlings spacing of 25 cm and 30 cm, leaving about 10,000 per mu. Visor shades can be used around noon. 4, late management. June-August is the fast-growing period of seedling production, suitable to make up for phosphorus and potassium fertilizers, base fertilizers may not be top-dressed, spraying potassium dihydrogen phosphate 1-2 times, base fertilizer lacking to recover urea 10-15 kg, and no longer top-dressing after August Against leggy. 5, seedling processing. The dwarf treatment of seedlings is a key technical measure for the cultivation of Toona sinensis. Seed height control in 1-1.2 meters, set the tree. There are two methods: (1) manual treatment: seedlings grow to 60 centimeters to pick hearts, and collateral shoots to 30 centimeters to buds, and so on, but this method is not conducive to material accumulation; (2) paclobutrazol treatment: from late June to early July Every 5-7 days with 15% paclobutrazol 500 times sprayed 2-3 times, the role is better. 6, pretence. Spraying 700-800 mg/kg ethephon in late October to speed up nutrient flow and accelerate defoliation. Keep more roots when raising seedlings. Torreya grandis leaves have a natural dormancy period of 17 days and can be used to break their dormancy. The method is: dig a groove of 0.5m deep and 1-1.5m wide at the backside sunny side. Put the seedlings a little bit and then turn the head to the west or south to put it in the ditch. Sprinkle the water in the roots, after about 20 days 10°C The low temperature can be. 7, greenhouse cultivation (1) Transplanting: Transplanting sweet locust seedlings into greenhouses through artificial planting. Upper sheds should be topped with organic manure, phosphorus and potash fertilizers, and 300 kg of decomposed organic manure, 50 kg superphosphate, and 50 kg can be used. The ternary compound fertilizer has 100-150 seedlings per square meter, 80-120 perennial seedlings, watering after planting, and covering again after 5-10 days. (2) culture management: day temperature control at 20-25 °C, 10 °C or more at night; depending on the situation of the seedlings can be sprinkled water for about 10 days. After the shoots are harvested, 15 to 20 kg of urea is poured into the mu, and potassium dihydrogen phosphate can also be used to spray them. The shoots can grow to 20 cm or more and be harvested. When harvesting, the buds are picked first and then lateral buds are harvested, generally harvested once in 8-10 days, and harvested 5-7 times. The top buds were all harvested. Lateral buds were left with 2-3 leaves in the stem, and about 1,200 kg were harvested per acre. 2-3 days before each harvest, foliar spray fertilizer, topdressing 10-15 kg of urea and timely watering after harvest. 8, seedling management. Before and after the Qingming to Guyu, the temperature was stable at 10°C or more. The seedlings were planted for 3-5 days. The saplings were moved to the outside and transplanted at 20 cm and 30 cm. 8000 plants were planted per acre. The upper part was cut at 15 cm above the root. , other for ibid. Usually nursed once, can produce about 5 years. Http:// Dried Fruit,Freeze Dried Strawberries,Dehydrated Fruit,Dried Goji Berries Xi'an Gawen Biotechnology Co., Ltd , https://www.seoagolyn.com
