我国农业生产中的施肥理论与实践误区

Misunderstandings over the Theory and Practice of Fertilization in Agricultural Production in China

分析了我国当前农业生产中植物营养学理论及其施肥实践存在的几个误区:植物必需营养元素分类误区;植物碳、氢、氧来源认识误区;植物必需营养元素生产重要性评价误区;化肥及有机肥肥效评价误区。针对误区带来的生产问题,提出了植物必需营养元素四级分类法及研制厌氧堆肥等对策措施。

In this paper, several misunderstandings over plant nutrition theory and fertilization practice in agricultural production in China had been analyzed. One is the misunderstanding over the classification of essential nutrients for plants. The second is the misunderstanding over the sources of plant carbon, hydrogen and oxygen elements. The third is the misunderstanding over the importance of production of essential nutrients for plants. And the fourth is the misunderstanding over the evaluation of chemical fertilizer and organic fertilizer efficacies. Regarding the production problems caused by those misunderstandings, a four-level classification of plant essential nutrients and solutions such as development of anaerobic compost are proposed.
