几种不同生产工艺的复混肥对冬小麦的影响

Effect of Compound Fertilizer in Different Techniques on Yield of Winter Wheat

为了改变生产者在冬小麦基肥施用上选用复混肥生产工艺的盲目性、随意性,解决因施肥不当造成小麦产量难以提高问题,采用大田试验方法,于2010—2012年在典型地块开展了市场上常见的几种不同生产工艺生产的N、P2O5、K2O配比为15-15-15的硫基复混肥每公顷基施600 kg对小麦的影响对比试验研究。结果表明,掺混肥工艺、法国AZF工艺较其他处理极显著提高了小麦产量和效益,这2个处理间产量差异不显著,效益差异极显著;每公顷分别增产3262.0kg、3168.0kg,增产率65.7%、63.8%;分别增收5278.20元、4252.80元。得出在冬小麦基肥施用上应首选掺混肥工艺、法国AZF工艺生产的复混肥。

In order to change the way of applying compound fertilizer technique for winter wheat randomly and blindly,meanwhile solving the problem on low yield of winter wheat owing to improper fertilization,a field trial was researched by comparing the results of several common S-based compound fertilizers made in different technique including different compound fertilizer technique,mixed fertilizer and French AZF,in the typical farmland during 2010-2012.The trial was designed for base fertilizer 600 kg/hm2 by proportion of N-P2O5-K2O=15- 15- 15.The result showed that the yield and economic benefit of winter wheat applied in mixed fertilizer technique and French AZF technique were increased significantly.There was little difference in yields,but more in economic benefits between these two treatments.The yield of wheat applied in mixed fertilizer technique and French AZF technique treatments were increased by 3262.0 kg/hm2 and 3168.0 kg/hm2,with growth rate of 65.7% and 63.8% compared to CK,and the economic benefit increased by 5278.20 yuan and 4252.80 yuan.The research concluded that the mixed fertilizer and French AZF technique should be the first choice for base fertilizer on winter wheat.
