摘要
随着吉林省种植结构的相应调整,许多农户进行了大规模的种植,并取得良好的经济效益,种植面积逐年扩大。为了适应向日葵生产的新形势,通过对施硼肥对食用向日葵产量的影响研究,来确定最佳硼肥施肥量,达到抗病增产的目的。结果表明:施用硼肥可明显提高向日葵产量,且在一定范围内,随着硼肥施用量的增加,向日葵产量呈上升趋势,当达到临界值时,继续增加施用量,增产效果不明显。
With the adjustment of planting structure in Jilin Province,many farmers have carried out large-scale cultivation,planting area expanded year by year, and achieved good economic benefits. In order to adapt the new situation of sunflower production, effect of boron fertilizer on the sunflower yield was studied.The results showed that the application of boron fertilizer could improve the yield of sunflower, and within a certain range, the yield of sunflower is rising with the increase of fertilizer application.When reached its critical value, effect of yield-increasing was not obvious.
