【摘要】 试验证明,农用稀土化合物拌种或喷施均可提高冬小麦籽实产量。拌种以每公斤种子用100毫克,喷施用300—500ppm 效果最好,理想的喷施时期为起身一拔节期。通过省内多年多点示范推广均表现稳定增产的时事,还证明稀土化合物处理冬小麦做为一项有效增产措施在我省是可行的。更多还原

【Abstract】 This paper reportel that winter wheat yield was increased with the Agricultural Rare Earth Compounds (AREC) that was used to dress seeds or spray leaf Surfaces.The amount for seed dressing with AREC was 100mg/kg seed and optimum Consistency for leaf Surface spraying was 300-500 ppm.The ideal spraying stage was from viviving to elongotion stage.Through many-gear and mony-place experiments resuets in our province,Wheat yield was sfabey incre- ased.It was proved that it was availafle measure that winter wheat was treated with AREC.更多还原
