喷灌条件下垄间覆膜对大豆生物产量影响的试验研究
Study on soybean production influenced by overlay film between furrows under spraying irrigation
【摘要】 根据2003年在黑龙江省甘南县进行的大豆垄间覆膜试验,通过数据处理分析,研究了垄间覆膜的增产效果。结果表明,覆膜的增产率达到14.6%,百粒重增加8.3%。
【Abstract】 This article is based on the experiments of overlay film between soybean furrows in Gannan County,Heilongjiang Province in 2003,researched the production-enhancing effect of the overlay film between soybean furrows.Through the data processing,the production-increasing ratio has reached to 14.6%,the total weight of one hundred grains increased 8.3%.
