| 摘 要： | 为了缓解桉树千旱胁迫、促进按树生长和提高土壤肥力,该文采用稻草覆盖下施配方肥处理研究按树生长、土壤养分和水分变化情况,结果表明：①与农民习惯施肥相比,单施配方肥和在配方肥基础上稻草覆盖处理分别提高桉树地径19％和20％,胸径13％和21％;②在配方肥基础上稻草覆盖处理可以降低土壤温度,有效保蓄土壤水分含量,提高桉树叶片水势,缓解干旱胁迫下桉树水分需要,增加土壤养分含量,起到抗旱和培肥作用.

| Abstract: | Effect of formula fertilizer on the growth of eucalyptus,soil nutrient and moisture content under straw mulching was studied to alleviate drought stress,promote the growth of eucalyptus and improve soil fertility.The results show that：①conpared with local custom fertilization,single application of formula fertilizer and the fertilizer based on straw mulching treatments increased 19％ and 20％ on ground diameter,13％ and 21％ on diameter at breast height of eucalyptus,respectively ;②the formula fertilizer under straw mulching treatment was helpful to reducing soil temperature,effectively conserving soil moisture content,increasing leaf water potential of eucalyptus,needing to alleviate water under drought stress,improving soil nutrient content. |
