摘要
本文主要通过对青海耕地及农田土壤养分状况、种植业结构、肥料施用现状等方面进行调查、分析、阐述了土壤养分变化趋势、平衡施肥技术研究进展及物化产品在生产中应用。针对青海高原地区农田状况,建议增施有机肥,改良培肥地力,提高有效水分利用,加强施肥技术体系研究,提高耕地质量,达到标准化生产要求。
The paper investigated and analyzed the soil nutrient status of Qinghai cultivated land and farmland, planation structure and fertilizer applying status, the soil change trend. Progress on balanced fertilization and application of materialized products in production were discussed, Aimed at the plateau farm land status the suggestion that increase the organic fertilizer, improve and enrich fertility, improve effective water utilization, strengthen fertilization technique were put forward, thus the quality of cultivated land was improved then the standardization production requirement was reached.
