- 摘要:
- 通过调查研究认为, 哈尔滨市化肥施肥结构有明显的地域性和依作物种类分配的特点, 这种施肥结构存在很多问题, 必须进行调整。通过化肥施肥结构的调整, 增加氮钾肥用量, 降低磷肥用量, 可以显著提高全市粮食作物的产量和质量, 年降本增效获纯经济效益达2 .45 亿元, 对发展质量效益农业具有重大意义。
- Abstract:
- Through invest ig ation , it has been thought that there are clearly characters of region and distribution according to crops in chemical fertilizer applying st ructures in Harbin and there are so many problems in this st ructure , w hich must be regulated .Adjusting the chemical fertilizer structure , increasing N .K .fertilizer usage and reducing P fertilizer usage , the crop yields and quality of the w hole city may be increased .Annual pure economical benefit will reach to 245 millio ns Yuan .This has g reat sig rnifucance in developing quali ty and benefit ag riculture .
