| 摘 要： | 目前由人工合成的有机螯合微量元素肥料，因价格昂贵不能在农业生产中广泛应用。本研究采用丰富廉价的有机肥料，经转化提取的天然螯合剂与微量元素螯合研制的天然螯合微肥，在多种作物上施用，证明能促进作物对Ｎ、Ｐ、Ｋ和Ｆｅ、Ｍｎ、Ｚｎ、Ｃｕ等微量元素的吸收。明显提高作物的产量，改善品质，并不同程度地提高作物的抗病能力．

| Abstract: | The synthetic chelate micronutrient fertilizers can not be widely applied for their high cost. The object of this study was to test the effects of a naturally-chelate micronutrient fertilizer, in which the chelator was extracted from cheap organic fertilizers, on crop yields. Theresults showed that this new complex fertilizer increased the uptake of P, K, Fe, Mn, Zn,and Cu by the crops, and crop yields manured to soil. The results also showed that the naturally-chelator complexed micronutrient fertilizer improved the quality of crop products and enhanced the ability of diseases resistance of crpos to various extent. |
