增施有机肥对砂姜黑土地小麦生育特性及产量的影响

Effect of Applying Organic Manure on Growth Characteristics and Yield of Wheat in Shajiang Black Soil

针对砂姜黑土地小麦(Triticum aestivum L.)生产上存在的不足,设置不同的施肥模式,考察其对小麦生育特性及产量的影响,以为砂姜黑土地高产高效施肥提供依据。试验结果表明,在一定施肥水平下增施化肥对提高小麦经济产量作用不大,增施有机肥可以显著提高小麦产量,并得出了相应比较高产的施肥模式。

According to the deficiency of wheat(Triticum aestivum L.) production in Shajiang black soil,different fertilization mode was designed to examine its impact on growth and yield of wheat,providing basis for high-yielding high-efficiency fertilization.The results showed that under certain levels of fertilization,application of chemical fertilizer had little effects on increasing wheat yield;while application of organic fertilizer could significantly increase the yield of wheat.A relatively highyield fertilization mode was obtained.
