有机无机肥料配合施用对春小麦产量品质影响的研究

有机无机肥料配合使用,能显著提高作物产量,尤其当农肥与氮肥配施时,可使小麦增产16.7%—152.1%:农肥与磷肥配施增产5.6%—40.0%:农肥与氮磷配施同农肥加氮肥的产量相近似。还可使麦草增产23.6—324.5%,提高麦草和秸秆中全氮的含量,从而改善作物的品质。

Effect of Coordination Application of Organic and Inoganic Fertilizers on Yields and Qualities of Spring Wheat

The coordination application of organic and in orguuic fertilizers, being pregressive direction in fertitizer application techniques in China, has incrcased yields of crops. The. study indicated that the coordination application of manure and N-fertilizer increased grain yield of wheat by 16.7—152.1%, straw yield by 23.6—324.5% which was available to alleviate the deficicncy in feed, fertilizer and material for heating in low-yield area, and also to improve crop qualities due to incrusing toal content of N in grain and straw. The coordination application of manure and N and P-fertilizers had the similar upsurge tendancy to that of the manure and N—fertilizer while the coordination application of manure and —fertilizer laised wheat yield only by 5.6—40.0%.
