摘要
麦饭石是一种含有多种徽量元素的次火山岩半风化物，具有多种生物活性。盆栽试验表明：红壤旱土根际施用麦饭石处理小麦，根重和株高、有效分蘖、穗长、实粒数、千粒重、地上部分干重均显著增加，籽粒产量比对照增产１２％。植株、根、茎、籽粒养分分析证明，麦饭石能促进小麦根系发育，增强小麦对Ｎ，Ｐ，Ｋ营养的吸收，并促进Ｎ，Ｐ，Ｋ养分向小麦籽粒的输送．
MS(MedicaI Stone)is a type of weathering product from meta-volcanic rock,containing many kinds of trace microements and having biological activities.The results ofpot experiments showed that,after applying MS to wheat,the root weight,plant height,ef-fective tellerings,ear length,number of filled grdins,weight per 1 000 gains and dry materialweight of the upland plant all increased significantly.The analysis results of upland plant,root,stem and nutrient contents of grain demonstrated that MS application enhauced rootgrowth,N,P,K uptaking abieity of wheat plant and translocation of N,P,K to grains。
