长期定位施肥对暗棕壤肥力和作物产量的影响
Effects of Long-Time Fertilization on Crop Yield and Soil Nutrients of Dark Brown Earth
摘要
Abstract
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.关键词
