摘要
根据29年肥料效应长期定位监测试验结果,研究了不同施肥处理对作物产量及土壤肥力、养分水平等指标的影响。结果表明:不同施肥处理作物产量差异较大,有机肥和氮、磷化肥的配合施用对提高作物产量、增加土壤养分作用十分明显。
The effects of different fertilizer application ways on crop yield and soil fertility were studied based on a 29-year located fertilization field experiment in dark-brown soil farmland system in Heihe city,Heilongjiang province of Northeast China.The results showed that there is great difference in crop yield and the content of soil nutrients between different fertilization treatments,especially for a combination of organic and chemical nitrogen and phosphorus fertilizers which played an important role in improving crop yields and increasing the nutrient content of dark brown soil.
