精制有机肥与化肥配合施用对专用小麦产量的影响

对强筋小麦和弱筋小麦施用不同肥料组合来验证对不同类型小麦的影响。结果表明：强筋小麦的产量、千粒重、穗数和穗粒数随有机肥施用量的增加呈抛物线增加趋势。在N、P、K总量相同的条件下,当化肥与精制有机肥比例为6∶4时弱筋小麦产量最高。在一定程度上减少化肥用量而增施精制有机肥,小麦产量可明显提高。

Effect of Application of Mixed Refined Organic and Chemical Fertilizer on the Yield of Wheat for Different End Uses

The effect of application of mixed refined organic and chemical fertilizer on the yield of the strong gluten wheat and weak gluten wheat was conducted. The result indicated that with the fertilization increase of organic fertilizer, the yield, 1000-grain weight, spikes, the number of grains per spike of strong gluten showed a parabpla form trend. In the condition of total N, P, K were the same, when the rate of chemical fertilizer and refined organic fertilizer was 6：4, the yield of weak gluten wheat was the highest. The yield of weak could significantly increase on some degree of chemical fertilizer, but increasing organic fertilizer.
