In 1983, the application of plastic film ground covering technology in Longcaoping Forest Area was used to carry out nursery experiment, and good results were obtained. The test species are: ash, tree (sowing), Buxus Yang, white wax (cuttings), Mei County Catalpa bungei, Lankao long Phyllis (buried root). Before nursery, turn the nursery upside down twice, remove weeds and stones, fertilize (Buxian Yang not applied), irrigate, and soil disinfect. Eviscerate, prickly heat at the end of 90 cm, shoulder width 70 cm. Paulownia which Paulownia, Shoulder 50 cm, 10-15 cm high, slightly higher middle noodles. Then covered. Thin film and clay surface work closely with soil, soil compaction on all sides. Cuttings nursery, in accordance with the tree species of different spacing requirements, drilling in the membrane. After cutting or rooting, in the hole
