摘要
为解决翠菊移栽后缓苗期长、幼苗生长发育缓慢等问题,试验通过幼苗移栽时蘸根、穴施等方法,进行了保水剂在翠菊移栽中应用效果的研究。试验结果表明:翠菊移栽时使用保水剂,可使缓苗时间缩短2~3d,光合速率提高33.87%~53.23%,叶片水势降低-9.794~-4.897bar。两种处理中,穴施保水剂比用保水剂蘸根效果好。由此可见,在翠菊移栽时适当使用保水剂,是缩短缓苗期、促进翠菊生长发育以及提高抗旱能力的有效途径,值得推广应用。
In order tO resolve the matter about long comeback period and slow growth rate of seedling after transplantation, the two ways of wetting roots with water-retaining agent and using water-retaining agent in planting aperture were applied, and the application effect of water-retaining agent on transplantation of Callistephus chinensis Nees. was investigated in this experiment. The results demonstrated that the using of water-retaining agent could shorten comeback period by 2~3d, enhance photosynthesis rate by 33. 87M ~ 53.23M and reduce water potential by-9. 794~-4. 897 bar. The effect of using water-retaining agent in planting aperture was more obvious than that of wetting roots with water-retaining agent. This showed that the proper using of water-retaining agent in transplantation was the effective approach to shorten comeback period, accelerate growth and enhance the ability of resisting drought, and it is worth popularizing and applying in agricultural production.
