Taxus chinensis seeds seedlings (below) III. Field management 1. Before the shading seedlings of the seedlings are unearthed, the shade scaffolding must be erected and the shed height is 1.7 meters. In the days of the dog days, the seedbed should be shaded. 2. Pest and disease control seedlings emerged from the rainy season after they were unearthed. Due to excessive rainfall, high air humidity, and seedlings susceptible to pathogenic bacteria, root rot and damping-off occurred, resulting in failure of nursery. Therefore, the emphasis is on "prevention". When the seedlings are unearthed, spray 800 times thiophanate or half Bordeaux mixture (0.5 pounds of copper sulfate, 0.5 pounds of lime, 100 pounds of water) spray every 7 days to the stems and leaves of seedlings. , foliar spray. 3. Intertillage, weeding and fertilization During the growth of seedlings, pay attention to weeding and loose soil and improve soil ventilation conditions. The principle of weeding is: except small, except early. Seedlings in the early stage of growth are topdressed with nitrogen and phosphate fertilizers. They are formulated with 10% diluted human fecal urine plus 0.4 kg of urea and applied once every half month. It was stopped in mid-September and the shady nets were removed and the scaffolds were left for reuse each year. 4. If the seedlings are transplanted due to uneven seeding, the seedlings will be too dense and too thin. From the end of May to the middle of June, the seedlings must be transplanted and intercropped and thinned. The transplanting method is: Select the rainy day or transplant after the rain, cover the moss, drizzle with water and transplant. Four-year-old seedlings management Before the seedlings are transplanted, the shade scaffolds are well-arranged, and trails and weeds are cleared in time. Increase the top dressing for thin and thin seedlings to promote growth. Through careful management, the annual seedling height is 12 to 25 centimeters, the seedling height is 30 to 35 centimeters for the second year, the diameter is 0.5 centimeters thick, and 60,000 seedlings per mu are produced.
