RLH营养液提高油松成活率及生长量技术研究

Effect of RLH Nutrient Status on Pinus tabuliformis Growth and Physiological Activity

研究了RLC营养液对油松生长及生理活性的影响。结果表明,使用RLH营养液,1)可以提高油松移栽成活率和新梢生长量,比根宝处理的分别提高了9.67%和22.87%.2)叶绿素含量增加,两次测量比根宝处理的分别提高了14.78%和7.77%.3)针叶中SOD和POD酶活性极显著高于对照,两次测量比根宝处理的分别提高了43.63%,29.89%和27.85%,42.50%;CAT酶活性也显著高于对照,两次测量比根宝处理的分别提高了4.17%和9.64%;MDA含量极显著降低,两次测量比根宝处理的分别降低了11.54%,25.59%.4)脯氨酸(Pro)含量极显著高于对照,两次测量比根宝处理提高了41.48%和19.56%.

Effect of RLH nutrient status on Pinus tabuliformis growth and physiological activity were studied. The results showed that using RLH nutrient status, 1 ） can improved transplanting survival rate and growth of Pinus tabuliformis; 2） chlorophyll in two tests content was higher in two tests than CK, and improved 14. 78% and 7.77% than ＂genbao＂; 3） activities of both SOD and POD in needles in two tests were increased and extremely significant than CK, increased by 43.63% ,29. 89% ~11 27. 85% ,42. 50% than ＂genbao＂ ; activites of CAT was also significantly higher than contrasts; MDA content extremely significant decreasing than ＂genbao＂ treat respectively 11.54%, 25. 59% south, reduce ;4） Proline （Pro） content in two tests is extremely significant than the control, improved caught 41.48% and 19. 56% than ＂genbao＂
