摘要
应用不同施量的保水剂进行膏桐造林试验.结果表明,加施保水剂不仅对土壤水分有显著的改善作用,且能提高膏桐苗木的生长量及造林成活率.不同保水剂施量中以穴施20 g最优.
The afforestation experiments of Jatropha curcas were conducted with different dosages of water retention agent. The result showed that the application of the agent could not only improve water content in the soil greatly, but also enhance the growth of Jatropha curcas＇stock and survival rate of the afforestation. Among different dosages of water retention agent, the scheme with 20 grams applied in holes was the most optimal.
