淮北地区夏直播花生高产栽培技术

Study on High-yielding Cultivation Technique of Directly Sowing Peanuts in Summer in Huaibei Region

笔者于 1997年开始 ,借鉴外地成果 ,结合本地实际 ,进行了夏直播花生的高产栽培技术研究。经过 3a的试验、探讨 ,采取更换品种、深翻改土、平衡施肥、化控等农艺措施 ,摸索出了一套适合淮北地区生产水平的夏直播花生高产栽培技术。经小面积试验验证 ,产量达 882 4.5kg/hm2 ,比对照增产 3 0 .8%左右 ,大面积种植增产 12 %～ 18%

The cultivation technique of directly sowing peanuts in summer for high yield had been studied since 1997,based on the combination of advanced techinque introduced and actual local production.The techniques including the renew of peanuts varieties,deep plough and fertilizer application etc.were experimented,and a set of cultivation techniques with high peanut yield were applied in Huaibei Region.The yield of peanut was as high as 8824.5kg/hm 2 in small area trial and the yield increasment reached to 30.8% more than that of check experiment.
