| 摘 要： | 以17年的微量元素肥料定位试验为背景，研究了长期施用锌肥条件下小麦的需锌特点和增产效应。施人锌肥后，小麦对微量元素锌的吸收明显增加，籽粒中含锌量增加率为18．8％，秸秆含锌量增加率为41．1％。小麦吸锌量在收获期达最大值，收获期籽粒多吸收13．99g/hm^2，秸秆多吸收23．67g/hm^2，常态年锌肥增产率为4．3％。干旱年增产率为3．7％，丰水年增产率为4．1％。应根据小麦需锌特点和效应，合理施用锌肥。

| Abstract: | Based on long-term applying zinc fertilizer with 13 years, the paper studies the character of absorption and efficacy increasing yield of wheat to zinc. After applying zinc fertilizer, the absorption of wheat is significantly increased on micronutrients zinc, the zinc content of whose grain increases 18.8%, and straw is 41.1%. The maximum of zinc absorption is in harvest time, when grain and straw separately increase 13.99 g/hm2, 23.67 g/hm2. The ratios of increasing yield are separately 4.4%, 7%and 7% among general year, dry year and rich rain year. So it is to set a rational application of zinc fertilizer by the character of absorption and efficacy increasing yield of wheat. |
