灌溉和施肥对土地整理区小麦产量和土壤养分的影响

Effect of Irrigation and Fertilization on Wheat Yield and Soil Nutrition in Land Consolidation Region

在新的土地整理区开展试验,探讨灌溉和施肥这2种措施对小麦产量和土壤养分变化的影响,结果表明,灌溉和施肥措施对土地整理区的小麦产量均有明显提高,能增加土壤微生物数量,提高土壤有机质、碱解氮、速效磷含量;灌溉措施增产效果更为明显,是限制小麦生长的主要因子。

A field experiment was carried out in a new land consolidation region to approach the influence of two measures of irrigation and fertilization to the wheal yield and the soil nutrient. The results showed that irrigation and fertilization had obvious enhancement to wheat yield, soil microorganie quantity, organic matter, alkaline nitrogen and available phosphorus content in land consolidation region.The irrigation measures could increase wheat yield more obviously and it was the major limiting factor for wheat growth.
