相同施肥量下增施中微量元素的效果研究

Study on Effects of Adding Trace Elements under the Same Amount of Fertilizer

[目的]提高江西省兴国县中低产田的产量水平,明晰微量元素在提高水稻产量中的应用效果。[方法]在水稻生长的不同时期,增施硅、锌、硫肥,了解微量元素对早晚稻产量水平的增产效果。[结果]早稻增加单一的微量元素均能取得较好的产量增幅。晚稻增施锌肥能增加谷粒饱满度,增施硅肥能促进壮秆、抗病,增施硫肥能促进分蘖。[结论]研究结果为水稻生产提供了技术借鉴。

Objective]The aim was to increase production levels of low-yielding fields in Xingguo County, and clear application results of trace elements for increasing rice yield. [Method] The effect of trace elements on production levels of early rice yield was getting, by applying silicon, zinc, sulfur, fertilizer at different grow periods of rice. [Result] Increasing single trace elements on early rice could achieve better output growth. Adding zinc fertilizer could increase grain plumpness of late rice, and adding silicon fertilizer could promote strong and inprove rod disease resistance, and adding sulfur fertilizer could promote tillering. [Conclusion] The results provided technical references for rice production.
