研究了长江三峡库区耕地的碳、氮储量,光合产物量及其影响因子;对库区耕地的氮肥增产潜力进行了试验并作出评价。认为推广留高茬等技术措施,可以提高养分的再循环率。
The carbon and nitrogen reserves, photosynthetic products and its influencing factors of cultivated land in the Three Gorges Reservoir Area of the Yangtze River were studied. The yield potential of nitrogen fertilizer in the cultivated land in the reservoir area was tested and evaluated. That the promotion of stubble and other technical measures to stay, you can increase the nutrient recycling rate.
