湘潭市农科所创造的“结构型”施肥法经多年试验证明,在一般肥水条件下,每亩可增产稻谷3-4%。1986年省粮油生产局组织有关单位进行验证性生产试验的结果表明,早、晚稻采用“结构型”施肥法均有增产效果,其中尤以杂交晚稻增产更为显著。据14个基点试验结果统计,杂交晚稻“结构型 Xiangtan City, agricultural created by the “structural” fertilization method after years of testing proved that, in the general fertilizer and water conditions, 3-4% of paddy per acre can be increased. In 1986, the Bureau of Grain, Oil and Production Bureau organized the relevant units to conduct the demonstration test. The results showed that both the early and late rice production increased with the “structural” fertilization method, especially the hybrid late rice increased more significantly. According to 14 basis points test results, late hybrid rice "structure type
