Abstract:

The new technique for planting hawthorn saplings covered with plastic film has been investigated. The result shows that survial rate of hawthorn saplings increased from 5.9％ to 12.3％; the average survival rate of saplings was 8.5％. Sprouting rate of saplings increased signilificantly. The growth of stem thickness was accelerated vigorously by covering with plastic film. There were higher improvements on the length of shoots and the percentage of strong branches. The economic effects were improved highly.
Then, the extension of the advanced technique was suggested.
