Ginkgo seeds 
 Seedling propagation 
 1. Planting seedlings (1) Select the nursery to choose flat, 
 Will be made to root out the pieces after cutting thin beds, bed width of 1-1.2 meters, the length vary. 
 Lee sunny, deep soil, loose and fertile soil, good drainage with water and place for the nursery 
 . Nursery full of cultivated deep plowing and blending of superphosphate applied per acre of manure or Tuza Fei 2000-3000 pounds. 
 (2) germination and planting. Seed can be sown in the autumn immediately after planting, germination not 
 . Such as spring planting should be primed. Tibetan sand before the vernal equinox out the seeds, placed in plastic greenhouses or greenhouse 
 , Pay attention to moisture, until more than 60% of the species can be planted after the nuclear buds exposed. Ginkgo seed drill can be used, 
 Sow, sowing grain, with good drilling results. In the nursery by 20 ~ 39cm spaced trenching, Goushen 2-3cm, sowing rate 5-8cm, 
 Sow the seeds should be placed north and south, in the same direction, radicle downward, seed sutures perpendicular or parallel to the ground, kind of sharp horizontal, 
 This high germination rate, normal root system, sturdy seedlings. Spacing by 8 a 10c m. Covered with fine soil after sowing, 
 And covered with plastic film, to be removed promptly after seedling film, allows early emergence and neat. 
 (3) seedling management seedlings growing season is short, stop growing early, developed root system, applied fertilizer to promote a clear 
 Into the seedling growth. In mid-April, mid May, mid-July once the applied fertilizer, fertilizer throughout the year 
 10 to 12 kg of urea per acre. Fertilizer for the fertilization should be measures, not too close from the seedlings to avoid root burn burning leaves. 
 Ginkgo fear of floods fear of drought, it should improve the drainage and irrigation. Ginkgo seedling growth slow, and weeds can compete 
 Weak and timely tillage weeding. 2. Cutting propagation of selected soil loose, well-drained soil 
 To enough base fertilizer,
