中国粮食生产中的肥料问题--“中国粮食高产我们可以做什么？”报告之一

分析了2007／08年度世界谷物供应状况及2006年我国粮食供求状况，认为人口增长、耕地减少，中国的肥料产业应着力于满足粮食生产“强化栽培”之需要。分别讨论了大豆、玉米、水稻、小麦生产中的肥料供应问题。中国粮食生产中的肥料问题不是数量不足，而是质量与结构问题；质量问题不是养分含量低，而是养分偏废；构成问题是氮肥施用太多，但硝态氮肥太少，高浓度肥料太多。提出了构建高的土壤化学肥力、物理肥力、生物肥力的建议。

Problems existing in chemical fertilizer for China's grain production -Report I "What should we do for high grain yield in China"

The world＇s grain supply in 2007/08, and China＇s grain supply and demand situation in 2006, are described. It is considered that with the increasing population and reducing arable land, China＇s fertilizer industry should focus on meeting the needs of agricultural production by intensified cultivation. The problems in chemical fertilizer supply for soybean, maize, rice and wheat productions are discussed respectively. The fertilizer＇s problems for China＇s grain production are in its quality and components, not in its quantitative insufficiency, the quality problem means nutrient unbalanced, not low analysis nutrient; the components problems mean overdose of nitrogen fertilizer and overmuch high analysis nitrogen fertilizer, however insufficient nitrate nitrogen fertilizer. The suggestion is proposed for building up the soil with high chemical fertility, physical fertility and biological fertility.
