为进一步摸索大面积花生高产生育规律及栽培技术,在连续三年连片600亩花生亩产350公斤以上的基础上,1987年我们会同省、市、县有关业务部门,在东芹湖村搞了大面积花生高产攻关试验面积84亩,品种为鲁花7号(原临沂73—43),经省、市、县科研部门多次测产验收,平均亩产达559.89公斤,实收亩产541.97公斤,创全省大面积花生高产新记录。丰产方土质为壤土,土壤有机质为0.97％,全氮0.071％,碱解氮56ppm、速效磷12.4ppm、速效钾82
In order to further explore the law of large-scale peanut high yielding fertility and cultivation techniques, contiguous three consecutive 600 acres of peanut mu produce more than 350 kilograms, based on 1987, we will be with the relevant departments of the province, city and county, engaged in the East Qinhu Village Large area of peanut high yield key test area of 84 acres, the varieties of Luhua 7 (formerly Linyi 73-43), by the provincial, city and county scientific research departments repeatedly test production acceptance, the average yield of 559.89 kilograms, real yield 541.97 mu Kg, creating a new large area peanut high yield new record. Soil fertility for loam soil, soil organic matter was 0.97%, 0.071% of total nitrogen, alkali hydrolysis of nitrogen 56ppm, available phosphorus 12.4ppm, available potassium 82
