摘　　要：Under the condition of reduced application of nitrogen fertilizer, the impact of silicor）, zinc and boron on rice growth was investigated by field experiment. The results showed that when the application amount of nitrogen fertilizer was reduced by 20%, the application of silicon, zinc and boron did not reduce the yield of rice, but reduced the incidence of panicle blast in rice and optimized the structure of rice production.通过田间试验,研究了江汉平原地区氮肥减施条件下,硅、锌、硼等中微量元素配施对水稻生长的影响。结果表明,氮肥在减施20%时,配合硅、锌、硼等中微量元素,不会造成水稻减产,还可以降低穗颈瘟发病率、和优化产量结构。
