锰肥对小麦增产效应的研究

Study on the Manganese Fertilizer Effect in Wheat

锰肥试验表明，拌种、喷施和底施都能增加小麦产量，其增产模型为二次三项式。施用锰肥可以提高小麦体内锰的含量，并向穗部转移，增进小麦对氮的吸收，并转移到子粒中，提高蛋白质的含量，改善品质。

The experiment of manganese fertilizer shows that the seed dressing,spray fertil-izer and base fertilizer can all increase wheat yield with a model of quadratic three-part e-quation. Adding manganese fertilizer can raise its content in wheat and it can be transport-ed to the spikes,and it can also help wheat absorb Nitrogeon and transfer it to the grains,which will increase the content of protein and improve the quality of wheat.
