最近在我省几个地区调查访问,与各地农村同志交谈,了解到随着农村经济政策的改变,农民生产、生活已有很大提高。但因缺乏科技知识,忽视用地养地相结合,轻视有机肥料的积、制、保、种、施工作,单纯依靠化肥增产,盲目加大化肥施用量。如麦播底肥每亩碳铵多在百斤以上,高的有二、三百斤,磷肥也在百斤左右。越冬,返青追施尿素每亩二十斤以上,使化肥投资大,经济负担重,产量水平并没有显著提高。针对上述情况,兹以合理施肥问题作如下分析和探讨。
In recent days, we have conducted surveys and visits in several areas in our province and talked with the rural grats in various places. We have learned that with the change in rural economic policies, farmer production and living conditions have greatly increased. However, due to the lack of scientific and technological knowledge, neglect of the combination of land for cultivation and carelessness of the organic fertilizer production, production, preservation, planting and construction work, relying solely on fertilizer to increase production, blindly increase the amount of chemical fertilizer. Such as broadcast base fertilizer per acre of ammonium bicarbonate more than a hundred pounds, two or three pounds high, phosphate fertilizer is about hundred pounds. Overwintering, returning to green topdressing more than 20 pounds of urea per acre, so that fertilizer investment, economic burden, the output level did not significantly improve. In response to the above situation, I hereby make the following analysis and discussion on the issue of rational fertilization.
