稀土元素对植物效应,1933年起国外有陆续报导。我国1972年以来相继有许多单位开展了稀土元素在农作物上的应用研究,并取得较好的效果。为扩展稀土农用领域,开展了花生施用稀土技术与效果的研究。 一、材料和方法 1、供试花生品种为当地推广良种,供试稀土为稀土农用技术开发中心提供,稀土氧化物总量为38.7%。 Rare earth elements on the plant effect, since 1933 have been reported abroad. Since 1972, many units in our country have carried out researches on the application of rare earth elements in crops and have achieved good results. In order to expand the field of rare earth agriculture, research on the technology and effect of applying rare earth to peanut has been carried out. I. Materials and Methods 1. Peanut varieties for testing were local popularized varieties. Rare earths were provided for Rare Earth Agricultural Technology Development Center. The total amount of rare earth oxides was 38.7%.
