不同有机肥与无机肥配施对小麦产量、效益及土壤养分的影响

Effects of the Combined Application of Different Organic and Inorganic Fertilizers on Wheat Yield,Benefit and Soil Nutrient

为探讨不同品牌有机肥与无机肥配施对小麦产量、效益及土壤养分的影响,选用蕾特、名远、绿盈、邦禾4种品牌的有机肥开展研究。结果表明,有机肥与无机肥配施能够提高小麦产量,4种有机肥比常规施肥平均增产4.9%,其中增产效果最佳的是蕾特有机肥,比常规施肥增产9.1%,达极显著水平,穗粒结构上主要表现在增粒增重。在效益上,除蕾特有机肥比常规施肥增效1.8%外,其余3种有机肥当季效益均不明显。有机肥与无机肥配施对土壤养分含量影响较为明显,4种有机肥施用后土壤有机质、全氮、有效磷、速效钾含量分别增加2.2 g/kg、0.16 g/kg、0.8 mg/kg、2.8 mg/kg。4种有机肥中,蕾特有机肥在产量、效益及土壤养分含量变化上的表现优于其余3种产品,可在本地区示范推广。

In order to study the effect of combined application of organic manure and inorganic fertilizer on wheat yield, benefit and soil nutrient, four kinds of brand of organic fertilizers, such as Leite, Mingyuan, Luying, Banghe, were choosed to carry out this research. The results showed that the combined application of organic and inorganic fertilizer increased wheat yield,The average yield of four kinds of organic fertilizer increased by 4. 9% than that of the conventional fertilizer, and Leite gave the highest yield,which is 9. 1% higher than that of the conventional fertilization. The main reason is that the grain weight increased significantly. The fertilizer efficiency of Leite increased 1. 8% than conventional fertilizer, and the other three treatments are not obvious. Effect of combined application of organic and inorganic fertilizers on soil nutrients was obviously,the contents of soil organic matter, total nitrogen, available phosphorus and available potassium of the four organic fertilizers were increased by 2. 2 g/kg,0. 16 g/kg,0. 8 mg/kg,and 2. 8 mg/kg,respectively. The yield,benefit and nutrient change in the soil of Leite organic fertilizer are better than the other three treatments, which is recommended to demonstrate in the local region.
