磁化处理对绒毛白蜡嫩枝扦插生根的影响
Magnetic treatment on rootings of semi lignified twigs of Fraxinus velutina
摘要
Abstract
This research explored the effec t of magnets on the rooting of cutting slips, young seedling growth and biomass accumulation, and nourishing matter content in roots. Using a current year, sprouting branchlet from a cloned 3-year-old female Fraxinus velutina 'Lula-5' tree as cuttage material and three treatments of magnetized water spray (MW) , [magnetized water spray (MW) + magnetization blanket (MR)], and non-magnetized water spray (NMW) (the control) an experiment was carried out with a randomized complete block design trial. Results showed that: (1) the cuttage segment rootage ratio and the root effective index for (MW+MR) were greater and highly significant (P<0.01) compared to the MW and NMW treatments (control). The average diameter and length growth of young sprouting shoots in the (MW + MR) treatment were also signifi-cantly higher than MW and NMW treatments (P<0.05). (2) The fine root length, diameter, surface area, and volume showed no difference for the three treatments; whereas, all root morphology indexes in (MW + MR) and MW treatments were significantly higher than the NMW treatment (P<0.05). (3) Compared to the con-trol, nutrient content of N, P, K, Ca, Mg, Fe, Mn, Zn, Cu, and soluble sugar in the other two treatments was greater and highly significant (P<0.01), but Na was lower and highly significant (P<0.01). In conclusion, magnetization was beneficial for enhancement of the rooting rate, for promoting root growth as well as for biomass and nutrient accumulation. [Ch, 2 fig. 2 tab. 22 ref.]关键词
