1. Variety selection: In the winter production, the tulip bud should be selected for its bright color, rich luster, rich aroma, strong growth, good resistance to disease and cold resistance, and more reddish oil for production. ? 2. Germination and sowing: Toona sinensis seeds are oval, flat, reddish-brown, 5-7 mm long, with membranous wings at the upper end. Before the germination, the membranous wing was licked off by hand, then soaked in warm water with a new high-fat membrane for 4 to 5 hours, and then the seeds were wrapped in cotton and placed in an environment of about 25°C to germinate. During the germination process, the seeds are rinsed once daily with warm water at 25-30[deg.] C. to remove the harmful substances secreted by the seeds. When 30% to 40% of the seeds are exposed, they can be sowed. Depth of 1 to 1.5 centimeters, cover soil not too thick, soaked with film or straw after sowing moisture, about 7 days can emerge. Use 1 to 1.5 kg per acre, sowing time in mid-April. ? 3. Seedling management: after emergence and time seedlings, the seedlings can be divided into two times, the first time when the true leaves began to confuse, the second time when 2 to 3 true leaves when the Dingmiao, leave 10,000 per mu. . Seedlings of the fragrant seedlings are frightened, and the management of fertilizer and water should be strengthened in the early stage to promote seedling early growth. When the seedlings grow to 1.2 meters in July, the height of the control seedlings will be sprayed on the Kaowang No. 3 seedlings. After August, the seedlings will be controlled and the seedlings will be strengthened in the early morning. top. ? 4. Lifting and colonization: In the middle and late October, raise the seedlings with a leaf, dig 80 to 100 cm wide, and dig a depth of 1 to 1.5 meters. Place the sapling seedlings obliquely in the ditch, bury some earth in the roots, and pour some water. Water covers shading and promotes plant defoliation and dormancy. After 10 to 15 days, all the leaves fall off and can be moved to a solar greenhouse for planting. In the greenhouse, a width of 1 meter wide is made between the north and the south. When the seedlings are planted, they are planted in rows and rows, about 40,000 mu are planted, and the short seedlings are planted to the south, and the high seedlings are planted to the north. After planting water insulation. The temperature in the booth is controlled at 20-25°C during the day and above 10°C during the night. ? 5. Picking shoots: When the scented shoots grow to 15 to 20 cm, they can be picked.
