不同覆盖物应用在花生上的抗旱效果研究

Study on Drought-resistant Effects of Different Covers Applied on Peanut

对旱地花生进行了不同覆盖物的抗旱效果试验,结果表明:地表覆盖可以提高花生的叶绿素含量、光合速率、蒸腾速率和产量,不同处理的抗旱效果表现为:地膜覆盖>稻草覆盖>纸膜覆盖>不覆盖;稻草覆盖和纸膜覆盖可以有效减少地表径流量;从抗旱效果、经济效益和生态效益综合考虑,以稻草覆盖处理旱地花生最佳。

The drought-resistant effects of different covers applied on peanut in upland were experimented. The results showed that surficial covering could increase chlorophyl content, photosynthetic rate, transpiration rate and yield of peanut; according to drought-resistant effects, different covering treatments could be arranged as follows: plastic film>rice straw >paper film >no covering. Covering peanut with rice straw and paper film could decrease surficial runoff effectively. On the basis of drought-resistant effects, economic and ecological effects, the optimum treatment was covering with rice straw.
