花生是我省主要经济作物之一,近几年种植业结构调整的实践,进一步证明了花生生产是我省一大优势。为了适应农村商品经济的要求,当务之急是把花生生产优势迅速地转化为商品优势。 一、花生生产在农业结构调整中的地位作用。 随着种植业结构的调整,1985年我省花生生产的发展速度有了较大突破。据统计,全省花生收获面积1379万亩,单产379斤,总产达到52.27亿斤。比1984年面积扩大431万亩,总产增加16.27亿斤。花
Peanut is one of the main cash crops in our province. In recent years, the practice of planting structure adjustment has further proved that peanut production is a major advantage of our province. In order to meet the requirements of the rural commodity economy, it is imperative that the advantages of peanut production be rapidly transformed into the advantages of commodities. First, the role of peanut production in the adjustment of agricultural structure. With the adjustment of planting structure, the peanut production in our province witnessed a great breakthrough in its development speed in 1985. According to statistics, the province’s peanut harvest area of 1379 mu, yield 379 kg, the total output reached 5.227 billion kg. Compared with 1984, the area expanded by 4.31 million mu and the total output increased by 1,627 million kg. flower
