我县位于渭北“旱腰带”,原高沟深,水源奇缺,土地瘠薄。十年前小麦亩产一直是一百多斤,近年来生产水平提高较快。1974—1980年有四年亩产超过250斤,1975、76两年超过300斤。为了总结群众小麦抗旱增产经验,我们进行了调查。一、关于茬口布局旱原地区小麦茬口是决定产量的首要因素。越是旱薄,茬口的影响就越 My county is located in Weibei “drought belt”, the original high ditch deep, water scarce, barren land. Ten years ago, the yield per mu of wheat has been one hundred kilos. In recent years, the production level has been rapidly increased. From 1974 to 1980, four-year yield exceeded 250 kg per mu, exceeding 300 kg in 1975 and 76 in two years. In order to summarize the experience of mass wheat drought resistance and yield increase, we conducted a survey. First, on the layout of stubble Dryland wheat stubble is the primary factor in determining the yield. The more drought, the impact of stubble more
