花生是我国主要油料作物之一,解放后单产、总产虽都逐年上升,但仍未能充分满足需要。1958年在大跃进的新形势下,花生虽然由于春旱的影响,限制了播种面积甚至延迟了播期,但仍然获得空前未有的大丰收,单产约为1957年的138.5%,总产约增多一倍左右,为油料作物中增产比率最大的一个。突破了密度关是1958年花生得以大丰收的一个关 Peanut is one of the major oilseed crops in our country. After the liberation, peanut yield and output have risen year by year, but they still can not fully meet the needs. In the new situation of the Great Leap Forward in 1958, although the peanut restricted the sown area and even delayed the sowing date due to the impact of the spring drought, it still enjoyed an unprecedented bumper harvest, with a yield of about 138.5% in 1957 and a total contract output of about Doubled or so, the largest increase in the proportion of oilseed crops one.
