免耕套稻节水灌溉的基本苗与肥料运筹试验研究

Study on Basic Seedling Number and Fertilizer Application in Relay-intercropping Rice with No-tillage and Irrigation with Water-saving

免耕套稻具有节水节肥节本稳产高产等明显优势。试验研究在免耕套稻湿润灌溉的条件下,基本苗与肥料运筹最佳组合,以求在确保稳产高产的前提下,进一步节本增收,以解决当前水稻种植过程中盲目滥施化肥,导致肥料利用率下降,生产成本加剧,农业面源污染加重之痼疾。

There are obviously advantages of saving water, fertilizer cost reduction, high and stable yield and so on in relay--in- tercropping rice with no--tillage, The optimal combination of basic seedling number and fertilizer application was tested in the condition of relay--intercropping rice with no--tillage and moist irrigation, so as to save cost and increase income further in the prerequisite of steady high--yielding. The blindness in current cultivation of rice will be resolved, which resulting in decreased fertilizer efficiency, increased the cost of production and agricultural non--point source pollution due to address indiscriminate chemical fertilizer.
