依据粘质水稻土的保肥供肥性能和水稻需肥特性设计专用肥的使用技术，采用田间试验法校验确定。结果表明，对粘质水稻土，集中前期施肥的增产效果明显优于分散迟施，粘质水稻土水稻专用肥最适经济施肥量为每亩３５ｋｇ，最高产量的施肥量为每亩４３ｋｇ，继续增大施肥量，稻谷产量不再增加，但稻秆干物重仍可增加。 According to sticky paddy soil fertilizer for fertilizer performance and fertilizer required characteristics of the use of fertilizer designed to use field test method to verify. The results showed that the stimulation effect on clay soil and concentrated early fertilization was obviously better than that of disperse retardation. The optimum economic fertilizer amount was 35kg per acre and the highest yield was 43kg per acre. Increase the amount of fertilizer, rice production no longer increase, but the dry weight of rice straw can still increase.
