我区双季稻面积已达水田的96.5%,在粮食生产中居主导地位.要使粮食产量进一步提高,增加单产是我们的主攻方向,而合理施肥则是提高单产的一项重要措施。因此,结合本地区具体情况,研究双季稻高产稳产的肥料主体结构和肥料合理施用技术,这对明确肥料发展方向,充分利用资源,以维持双季稻区生态系统的养分平衡,达到高产低成本的要求,使施肥措施逐步规范化是有所裨益的。现就我们在这方面进行的一些试验研究结果综合整理如下。
The area of double-crop rice in our region has reached 96.5% of the paddy field and dominates the grain production. To further increase the grain output and increase the yield, we are the main direction, and rational fertilization is an important measure to increase yield. Therefore, combined with the specific conditions of the region, the main body of double-cropping rice with high and stable yield and reasonable application of fertilizers are studied, which clarify the development direction of fertilizer and make full use of resources to maintain the nutrient balance of the ecosystem in double cropping rice and achieve high yield Cost requirements, so that measures to gradually standardize fertilization is beneficial. The results of some pilot studies conducted in this regard are summarized below.
