【Abstract】 A thorough investigation has been made on the special economic plant-Sapium sebiferum in Dawu County, Hubei Province, and the various physical and chemical functions of the seed shells have been tested. Furthermore, series of planting experiments of individual and population separately in conservatory and in fields have been made, where the Sapium sebiferum seed shells assemble or disperse in the soil. The result indicates that there are abundances of the seed shells there and the shapes of them are perfect to retain water, they are steady and durable. They can be used widely in the sandy soil or loam to retain water and preserve soil moisture continuously. They can also improve the soil, save water and combat drought, besides, the exploiting belongs to a kind of comprehensive utilization on biotic resources. They can’t only protect the environment, but also accord with the demands of both ecology and economics.更多还原
