肥料是小麦增产的物质基础。科学用肥是充分发挥肥料经济效果,降低生产成本,夺取高产的重要途径,近几年来,各地贯彻执行了以有机肥为主,有机肥和化肥配合使用的方针,氮素化肥用量逐年有所增加,在施肥技术上有很大的改进,对提高土壤肥力,增加小麦产量起到了很大作用。但是,目前就全省肥料来讲,在肥料的数量、质量和施肥技术上,还存在不少急待解决的问题: 一是大部分地区肥料不足。农家肥数量少,质量差,绿肥恢复的慢,化肥供应仍然不足。这是我省小麦大面积大幅度增产的主要障碍。 Fertilizer is the material basis of wheat yield. Scientific use of fertilizer is to give full play to the economic effect of fertilizer, reduce production costs, an important way to capture high-yield, in recent years, throughout the implementation of the organic fertilizer-based, organic fertilizer and fertilizer with the principle of nitrogen fertilizer year after year Increase in fertilization technology has greatly improved, to improve soil fertility and increase wheat yield has played a significant role. However, as far as the province’s fertilizer is concerned, there are still many urgent problems to be solved in terms of the quantity, quality and fertilization of fertilizers: First, the shortage of fertilizers in most areas. Fewer number of poor manure, poor quality, slow recovery of green manure, fertilizer supply is still not enough. This is a major obstacle to a substantial increase in output of wheat in large areas in our province.
