山东省昌潍地区农科所从1971年—1978年在全区10个县30个大队探索花生高产规律,试验得出600～700斤/亩高产水平需要采用优良品种、深耕增肥、全苗密植,加强管理。在施肥方法上采用深浅结合双层施肥:分层施肥,一层施于25cm左右,一层施于100m处,比全施在播种沟内,增产5.1～24.4％。 Agricultural Science Institute of Changwei Prefecture in Shandong Province from 1971 to 1978 in 10 counties throughout the region 30 batches to explore peanut yield rule, the test obtained 600 ~ 700 kg / mu high yield level need to use good varieties, deep plowing, whole plant Close planting, strengthen management. In the fertilization method using the combination of depth and double fertilization: stratified fertilization, a layer of applied to about 25cm, a layer of applied at 100m, than the whole application in the sowing ditch, an increase of 5.1 to 24.4%.
