摘要
通过盆栽试验研究了植物抗旱性有关的指标和施用稀土微肥间关系。用０．０５％稀土微肥浸种及苗期喷施１０ｄ后，分别测定根系活力、叶片失水能力、萎蔫后吸收空气中水分能力与根系超弱发光。结果表明：除春小麦和蚕豆外，冬小麦、玉米、甜菜、豌豆、辣椒、紫花苜蓿等均因施用稀土而提高根系活力、延缓叶片失水能力，这些可能是稀土促进抗旱的原因。
The relation between some related idexes of
plant drought resistance andapplication of rare earth microfertilizer was studied through pot
cultivation. After 10days when 0.05%of rare earth microfertilizer was used in soaking and
spraying duringthe seedling stage,the root system activity,the leaf water loss ability and the
leaf mois-ture absorbing ability from air and the root system superglowing after wilting were
de-termined respectively. The results also showed that winter wheat,corn,sugar beet,pea ,chilli,
alfalfa, etc. except spring wheat and broad beans,improved their root activ-ity and prolonged
the leaf water loss ability because of application、of rare earth.Thismay be the possible cause
to promote plant drought resistance.
