位于我省庐江县东北大别山余脉下的20多万亩荒湖圩区粉砂粘壤型水稻土,长时间水稻产量很低。单季亩产徘徊在300～400斤之间。低产的原因何在及如何变低产为高产,是笔者在过去十多年(1964～1979年)土壤农化工作中一直关心着的一个重要问题。 为解决这个问题,在坚持土壤农化工作必须为大田生产服务的方向、发扬一不怕苦二不怕累的精神、带着水稻为什么不能高产这个问题跑遍了圩区20多万亩土地的块块大田及分析
Located in Lujiang County, Shandong Province, Dabie Mountains in the northeast of more than 20 million mu of desert lake polluted silty clay soil, rice production for a long time is very low. Single-season mu production hovers between 300 to 400 pounds. The reason why low yields are and how low production is high yield is an important issue that the author has always been concerned about in soil agrochemical work in the past ten years (1964-1979). In order to solve this problem, in the direction of adhering to the work of soil agrochemicals for the production in the field, we should carry forward the spirit of not being afraid of hardships and exasperation and running over the land of over 200,000 mu of land in the polder area with the problem of why rice can not be produced in high yield.
