为了研究肥料对油茶北缘分布区采穗圃生长的影响,选择具有典型代表性的湖北省麻城县为试点,采用L9(34)正交试验设计的方法,探索了N,P,K不同营养元素及配比对单株穗条产量、穗条长度、穗条粗度及单穗芽数等指标的影响.结果表明,不同施肥处理间差异明显,变异幅度可达8.71%～15.50%;施肥效果显著,单株穗条数量较对照提高35.56%～87.96%,穗条长度较对照提高39.89%～73.60%,穗条粗度较对照提高10.53%～68.42%,单穗芽数较对照提高7.89%～34.21%;筛选的最佳施肥配方为N1P3K3,平均单株穗条产量332条,平均单穗芽数5.6个.含N100g,P2O5250g,K2O200g的施肥配方可在该地推广.
In order to study the effect of fertilizers on the growth of sprouts in the north edge of Camellia oleifera, we selected Macheng County, Hubei Province, as a typical experiment. Using L9 (34) orthogonal experimental design method, we studied the effects of N, P and K nutrition The results showed that there was significant difference among different fertilization treatments, with the variation range of 8.71% -15.50%. The fertilization The results showed that the number of panicle per plant increased by 35.56% -87.96% compared with the control, the length of panicle increased by 39.89% -73.60% compared with the control, the panicle increased by 10.53% -68.42% compared with the control, and the number of single panicles per spike increased by 7.89 % ~ 34.21% .The optimal fertilization formula for screening was N1P3K3, the average yield per plant was 332 and the average number of single spikes was 5.6.The fertilization formula containing N100g, P2O5250g and K2O200g could be popularized in this area.
