保水剂在草莓试管苗出瓶种植的应用试验

目的]为了研究保水剂在草莓试管苗移栽(出瓶)种植的应用效果。方法]采用不同量保水剂与珍珠岩基质混拌,研究了草莓试管苗移栽(出瓶)种植期间保水剂对小苗根发育及成活率的影响。结果]添加保水剂的处理对草莓试管苗移栽(出瓶)种植小苗的根发育影响不一,以处理Ⅲ(1%浓度)根发育最好,平均每个小苗根的发育数是12.25条;当基质中保水剂浓度1%时,浇水1次,污染3株,小苗成活率达98.9%,在实验范围内是最佳状态。结论]浓度为1%保水剂配方表现最好,显著地促进了小苗根发育,提高了小苗成活率。

Application Experiment of Water-retaining Agent Used in Transplanting Strawberry Test-tube Plantlets

Objective] The research was constructed to study the application effect of water-retaining agent on the strawberry test-tube plantlets planting out of bottle.Method] The different amounts of water-retaining agent mixed with perlite substrate were used to study the effects of water-retaining agent on the root development and the survival rate of plantlets were during the period of transplanting the strawberry test-tube plantlets.Result] The treatments of supplementing different amounts of water-retaining agents had different influences on the root development of transplanting the strawberry testtube plantlets.The root development in treatment Ⅲ with 1% water-retaining agent was best,with the average numbers of developed roots in every plantlet being 12.25.The optimum state in the experiment range was as follows: the water-retaining agent in the substrate at the concentration of 1%,watering once,3 plants being polluted and the survival rate of plantlets of 98.9%.Conclusion] The formula with the water-retaining agent concentration of 1% had better effects,promoted the development of plantlet roots and increased the survival rate of plantlet.
