阿勃、阿夫在我省不同地区与南大2419比较结果,几年来均有不同程度的增产,有些地区已经进行生产示范。但各地反映这两个品种需肥较多,为了进一步明确其需肥程度与产量的关系,有必要研究其在不同地区、不同施肥条件下的增产效果,以便作好品种搭配,并为扩大推广提出依据。因此,
Aberdef, Afh in different areas of our province compared with Nantong 2419 results have increased in varying degrees in recent years, some areas have been carried out production demonstration. However, it is necessary to find that these two varieties need more fertilizer all over the country. In order to further clarify the relationship between the degree of fertilizer needed and the yield, it is necessary to study the effect of increasing yield under different fertilization conditions in different regions in order to make good varieties and to promote the expansion Proposed basis. therefore,
