Toona sinensis loves temperature and is suitable for cultivation in an area with an average temperature of 8-10°C. The cold resistance ability increases with the age of seedlings. The annual wheat seedlings directly broadcasted with seeds may be frozen at around 10°C. Toon is light-loving and more resistant to humidity. It is suitable for growing in the fertile and moist soil around the riverside and the yard. Generally sandy loam is better. The suitable soil pH is pH 5.5-8.0. Toon cultivation and management methods are as follows:
1. Type selection. Generally choose red toon.
2. Cultivation and seedling cultivation. It is advisable to grow seedlings in arch sheds and greenhouses. Generally, the sowing rate per mu is 2-3 kg, and the planting rate is 100,000-120,000 per kg. However, the germination rate of toona sinensis seeds is low. Before sowing, the seeds should be soaked in warm water at 25-30°C for 12 hours. After soaking, the seeds are mixed with fine sand and sowed directly on the seedling bed. Seedling beds should be selected in areas with high terrain, loose, fertile, and good drainage and irrigation conditions, and adequate fertilizers should be applied early and a layer of straw should be covered after sowing to facilitate watering. Organic fertilizers should be used as the main fertilizer. It is advisable to cultivate in March and April.
3. Seedling management.
⑴ Germination period. It takes 7-10 days for seeds to emerge after accelerating germination, and 15-20 days for seed soaking and direct seeding. During the period from tillage to seedling emergence, the soil should maintain a certain humidity, water once every 1-2 days, the temperature in the day is 25℃, and the temperature is not lower than 8℃ at night.
⑵ Wheat seedling stage: Seedling height 6-7 cm with 2-3 true leaves, water once, combined with loose soil for weeding, the roots of the seedlings are 0.5 cm thick, spray with 100-200 times liquid urea, and use water after spraying Watering the seedlings. The seedlings have 4-5 true leaves and are about 10 cm high. The spacing of thinning, fixed seedlings and transplanting seedlings is 25 cm × 30 cm, and there are about 10,000 seedlings per mu. Sunshade nets can be used to shade around noon.
4. Later management. June-August is the fast-growing period of seedling production. Appropriate amount of phosphorus and potassium fertilizers should be made up. The base fertilizer is sufficient without topdressing. Spray the leaves with potassium dihydrogen phosphate for 1-2 times. The base fertilizer lacks 10-15 kg of topdressing urea. No topdressing after August. Anti-legacy.
5. Seedling treatment. The dwarfing treatment of seedlings is a key technical measure for toon cultivation. The height of the seedlings is controlled at 1-1.2 meters, and the tree shape is fixed. There are 2 methods: ⑴Manual treatment: the seedling grows to about 60 cm, topping, the side branches grow to 30 cm to remove buds, and so on, but this method is not conducive to material accumulation; ⑵ Paclobutrazol treatment: every month from late June to early July Spray 2-3 times with 15% paclobutrazol 500 times solution every 5-7 days, the effect is better.
6. Fake planting. Spray 700-800 mg/kg of ethephon in late October to accelerate nutrient return and defoliation. More roots should be left during seedlings, and the root length should be more than 20 cm. Toon deciduous leaves have a natural dormancy period of 17 days, and fake plants can break their dormancy. The method is: dig a ditch 0.5 meters deep and 1-1.5 meters wide at the back facing the sun, clean up the seedlings a little, turn the head west or south diagonally into the ditch, cultivate soil and sprinkle water on the roots, after about 20 days The low temperature is enough.
7. Greenhouse cultivation
â‘´Transplanting: Transplant toona sinensis seedlings into the greenhouse through fake planting. The fertilizer in the shed should be mainly organic fertilizer and phosphorus and potassium fertilizer. 300 kg of decomposed organic fertilizer, 50 kg of superphosphate and 50 kg can be applied per mu. The ternary compound fertilizer has a cultivation density of 100-150 seedlings per square meter and 80-120 perennial seedlings. After planting, sprinkle water and cover with film after 5-10 days.
⑵Cultivation management: control the temperature at 20-25℃ during the day, and above 10℃ at night; depending on the seedling situation, it can be sprinkled once in 10 days. After picking the buds, pour 15-20 kg of urea per mu, and spray with potassium dihydrogen phosphate. The buds can be harvested when they grow to more than 20 cm. When harvesting, first pick the top buds and then the side buds. Generally, it is harvested once in 8-10 days and can be harvested 5-7 times. All the top buds are picked, and the side buds are left with 2-3 leaves on the stem, and about 1,200 kg per mu can be harvested. 2-3 days before each harvest, spray fertilizer on the leaves, topdressing 10-15 kg of urea after harvest and spray water in time.
8. Seedling time management. Before and after Qingming and Guyu, the temperature is stable above 10℃, planting seedlings for 3-5 days, move the toon seedlings outside, and transplant them at 20cm×30cm, planting 8000 seedlings per mu, cut off the ground 15cm above the root Part, others are the same as above. Generally, one seedling can be produced for about 5 years.
