摘要
在培养液中加入高岭土,水稻生长正常,略优于纯培养液;加入蒙脱石,水稻长势前差后好,最后超过加高岭土培养的水稻。此外,在培养液中加入土壤粘粒矿物,水稻根系也发生不同程度的生理学变化,推测与土壤宜种性有关。
The rice seedlings cultured in nutrient solution(ie. N-sol) adding kao- line grow little better than those in N-sol. The seedlings cultured in N-sol adding montmorillonite grow badly at the begining, but better than those in N-sol adding kaoline at last. In addition, soil clay minerals in- duce the physiological changes of the roots. This suggests that there be some relationships between the types of soil colloids and the character of soils suitable to planting.
