旱地小麦施肥技术新探

The New Fertilizer Application Technique to wheat in Rainfed Lands

豫西旱地小麦生产目前多采取前作收后先耕翻晒垡,直到9月上、中旬才将各种肥料(粗、化肥)结合第二次耕地时施入土壤。本试验将施肥时间提前60～70d,于雨季来临前的6月下旬把各种肥料全部施上,以后遇雨只耙不犁,种时也不再翻耕。通过3年试验和一年大面积示范,此处理法较以往习惯施肥办法可增产10.1%～16.5%。

At present in dryland wheat production in the western part of Henan Province,theland is first turned with the ridges in sun drying after the prevoius crops are harvesteduntil the first and second weeks of september various kinds of fertilizer complex(ma-nures and chemical fertilizer)is placed when the land is plowed in the second time.Inthis test,fertilizer application time is advanced in 60～70 days before the rainy seasoncomes in the last week of June fertilizers of various kinds are applied to the fields.La-ter,the land is only raked without being plowed when rain comes.When wheat issown,there is no need to plow the land again.Three Years'trials and one year's exten-sion on a large area indicate that this method can increase wheat yields by 10.1%～16.5% in comparison with traditional fertilizer application method.
