摘要
用生物肥料——大民钾王对玉米进行拌种栽培试验 ,研究其增产效应 ,结果表明 :玉米果穗的长度、穗行数、单穗粒数、千粒重及籽粒产量均增加。其生理原因是由于大民钾王所含解钾菌能将土壤中的矿物钾、固定钾分解活化为有效钾 ,被玉米吸收利用 ,促进其根系发育 ,苗全秆壮 ,增强抗倒伏性能 ,同时增强植株光合作用 ,促进碳水化合物的形成和积累 。
The experiment in maize seeds treated with bio fertilizer—Daming Potash Fertilizer was carried out to study the efficiency of yield increasement.The result indicated that the length per ear,number of ear to row,seed number of ear,1000 seed weight and seed yield can be improved.The potash element in the soil can be dissolved through the application of Daming Potash Fertilizer,then be absorbed and utilized by maize crop.And the development of root system,the ability in seed germination,lodging resistance and photosynthesis can be promoted and the formation and accumulation of carbohydrate made maize yield increased.
