摘要
试验研究了无土栽培营养液的组成、电导率和pH对红熔幼苗生长的影响,结果表明:3种配方营养液都可用于红榕幼苗无土栽培,但C配方最节省成本。电导率为1．5 mS／cm时,植株生长优于电导率为0．5 mS／cm和1．0 mS／cm处理,但对根的影响不大。营养液的pH为5．5时有利于植株生长。
The effects of the composition of nutrient solutions and their EC （ electrical conductivity） and pH on the growth Ficus elastica variety Burgandy were studied. The results showed that all the three nutrient solutions were suitable for Ficus elastica hydro-culture, but the cost of formulation C was the lowest. An EC of 1.5 mS/cm was more favorable for plant growth than 0.5 or 1.0 mS/cm, but difference in EC had little influence on root growth. The optimum pH of the nutrient solution was 5.5.
