苏南地区稻麦不断连作 ,特别在高产条件下 ,必然会加速土壤某些养分的过度消耗。因此 ,通过不同氮、磷、钾配比的试验 ,探索各养分元素对产量的作用 ,寻求水稻最适宜的氮、磷、钾配比 ,为大面积水稻持续增产提供科学依据。1材料与方法1.1材料 试验地点在锡山市农科所 ,土质为
Continuous cropping rice and wheat in southern Jiangsu, especially in high yield conditions, will inevitably accelerate the excessive consumption of certain nutrients in the soil. Therefore, through the experiment of different ratios of nitrogen, phosphorus and potassium, the effect of each nutrient element on the yield was explored, and the most suitable proportion of nitrogen, phosphorus and potassium for rice was explored to provide a scientific basis for large-area rice yield increase. 1 Materials and Methods 1.1 Materials Test place in Xishan City Agricultural Science Institute, soil quality
