摘要： 以云母、硫磺、石膏、草炭、褐煤为辅加材料，试验对水稻吸氮和生长的影响，硫磺和石膏效果较好，特别是石膏，吸氮量达到3068.36mg/盆，比追肥增加10.6%；与追肥相比较，硫磺和石膏氮肥利用率分别提高2.2%和9.8%，产量提高2.6%和13.5%，并且改善品质。

Abstract: Use Mica, sulphur, gypsum, brown coal etc. as assist material, to test the influence on N-absorbing and growth of rice. The effects of sulphur and gypsum are better, especially gypsum, the total N-absorbing is 3068.36mg/pot, higher 10.6% than that of topdressing; Compared with dressing, Nitrogen utilizations of sulphur and gypsum are more than 2.2%. and 9.8%, yields are more than 2.6%.and 13.5%, respectively, and improve the quality.
