摘要
盆栽试验表明，灰泥田水稻分蘖始期和始穗期喷施ＬａＮｄｙ型离子稀土和复合离子稀土可分别使根际容积磁化率提高６．６１％～１９．７１％和５．０６％～３０．５１％，能显著促进水稻对养分的吸收和生长发育，并分别增产１０．０３％和１７．８０％．
The results of pot experiments showed that the ratio of magnetized rhizosphere of the rice plants increased by 6 61%￣19 71% and 5 06%￣30 51% respectively after the rice plants were applicated with LaNdY ionic rare earth and mixed ionic rare earth in the tillering starting stage and grain ear starting stage,rice growth and its nutrient uptake ability were stimulated significantly and the yields increased by 10 03% and 17 80% respectively.
