| 摘 要： | 在宜兴市万石镇开展了水稻不同锌肥用量对比试验，结果表明，在土壤有效锌含量
1.9mg/kg 的情况下，水稻增施锌肥对株高、穗数、千粒重等影响不明显，对增加每穗实粒数有明
显的促进作用；不同锌肥用量下，均有明显的增产作用，实际产量增幅在1.46%~9.27%之间，以施
用11.25kg/hm2锌肥所获得的产量和净效益最大。

| Abstract: | in Wanshi Town, Yixing City, a comparative experiment of different zinc fertilizer levels in
rice was carried out. The results showed that under the condition of soil available zinc content
(1.9mg/kg), the effect of adding zinc fertilizer on plant height, ear number and 1000-grain weight was
not obvious. It has obvious promoting effect on increasing the number of solid grains per panicle. The
actual yield increased by 1.46% to 9.27%, and the yield and net benefit of applying 11.25kg/hm2
zinc fertilizer was the largest. |
