| 摘 要： | 夏季采用稻草覆盖能显著降低果园土温,应用保水剂能显著提高果园中土壤含水量,两者结合应用,保水抗旱效果尤为明显。稻草覆盖与保水剂结合应用除能降低土温,提高土壤含水量外,还能显著促进脐橙果实的生长。研究结果表明,采取稻草覆盖、保水剂或稻草覆盖+保水剂均可保证赣南脐橙安全度过至少1.5个月的中长伏旱期。

| Abstract: | Soil temperature in orchard can be obviously reduced by covering straw in summer.Moreover,soil moisture content in orchard can be significantly enhanced by the application of water-retaining agent.The combination of covering straw and applying water-retaining agent has very remarkable water-retaining and drought-resistant effect,and it can not only decrease the soil temperature and enhance the soil moisture content,but also obviously promote the growth of the fruits of navel orange.The results of investigation showed that the combined utilization of straw-covering and water-retaining agent was able to ensure navel orange in the south of Jiangxi to safely get through the summer drought season that lasts for at least 1.5 months. |
