有机复合栽培基质对小麦施肥效应研究

Application of Organic Composite Growing Substrate on Wheat

为提高农林废弃物的再利用率,减少农作物栽培对施肥的依赖,以农林废弃物堆肥发酵基质为栽培基质,通过采用田间对比试验的方法,对冬小麦生长进行肥效对比试验。结果表明:与普通小麦肥以及化肥相比,有机复合栽培基质对小麦增长促进作用显著,小麦平均穗长比不施肥增长8.90%,比施化肥增长5.85%,比单施普通小麦肥增长5.49%;小麦平均穗数比不施肥增长40.79%,比施化肥增长17.11%,比单施普通小麦肥增长2.63%;小麦平均单产量比不施肥增长34.78%,比施化肥增长7.89%,比单施普通小麦肥增长2.01%。该研究可为农林废弃物在作物栽培方面的合理利用提供参考。

In order to improve the utilization rate of agricultural and forestry waste, reduce dependence on fertilizer to crop cultivation, forestry waste composting fermentation substrate for cultivating the matrix, by the method of field experiment, the growth of winter wheat was effect contrast tests showed that： compared with common wheat fertilizer and chemical fertilizer, organic composite cultivation medium enhanced the growth of wheat, organic composite growing substrate promoted significantly on wheat spike length, spike number, output growth compared with common wheat fertilizer and fertilizer. Among them, the average wheat spike length than no fertilizer increased by 8.90%, growth of 5.85% than the chemical fertilizer, compared with the single application of ordinary fertilizer for wheat growth of 5.49%; the average wheat spike number than no fertilizer increased by 40.79%, growth of 17.11% than the chemical fertilizer, compared with the single application of ordinary fertilizer for wheat growth of 2.63%; the average yield of wheat growth of 34.78% than no fertilizer, growth of 7.89% than the chemical fertilizer, compared with the single application of ordinary fertilizer for wheat growth of 2.01%. The research can provide a reference for the agricultural and forestry waste utilization in crop cultivation area.
