以南粳9108为研究对象,研究了不同减氮条件下施用蚓粪对水稻生长及产量的影响。结果表明,减氮10%、施用蚓粪400 kg/667 m²的处理水稻产量最高,与常规施肥相比增产3.3 kg/667 m²。在减氮10%的条件下,施用400 kg/667 m²蚓粪后促进了水稻地上部的生长,增强了叶片的光合作用,进而有利于提高灌浆速率,从而提高水稻的实粒数和千粒重,最终达到减肥增产的目的。

The effects of applicating vermicompost on the growth and yield of rice under different nitrogen reduction conditions were studied with experimental variety Nangeng 9108. The results showed that compared with the control （conventional fertilization）, the yield of rice was the highest in the treatment with 10% nitrogen reduction and 400 kg/667 m² vermicompost. Under the condition of reducing nitrogen by 10%, the application of 400 kg/667 m² vermicompost promoted the growth of rice above ground, enhanced the photosynthesis of the leaves and increased the filling rate, thereby increased the number of kenel and the thousand-grain weight, and ultimately achieve the goal of reducing fertilizer application and increasing rice yield.
