从去年农业部组织的山东、河北、河南、江苏、辽宁5个省花生生产考察来看,这5个省的花生种植面积和产量均占全国的一半以上。然而,近年来这些重点产区的花生重茬面积不断增加。据5省11个重点县调查,1980年花生面积为242.75万亩,重茬面积则高达80—100万亩,占30%以上。有的甚至达70%以上。例如,河北省迁安县22万亩花生,重茬面积占70%;河南省开封县24万亩花生,重茬10万亩,占40%;其他县一般都在20—30%。全国2,600多万
According to the inspection of peanut production in the five provinces of Shandong, Hebei, Henan, Jiangsu and Liaoning organized by the Ministry of Agriculture last year, the peanut acreage and output of the five provinces accounted for more than half of the country’s total. However, the stubble area of peanuts in these key producing areas has been continuously increasing in recent years. According to the survey of 11 key counties in 5 provinces, peanut area was 2.4275 million mu in 1980, and the area of stubble crop was as high as 80-100 mu, accounting for more than 30%. Some even reach 70% or more. For example, Qian’an County, Hebei Province, 22 million mu of peanuts, stubble area accounted for 70%; Henan Province, Kaifeng County, 24 acres of peanuts, stubble 10 million mu, 40%; other counties are generally 20-30%. More than 2,600 million nationwide
