摘要
为系统地研究野漆树轻型基质播种育苗技术,采用4因素3水平正交设计,通过施肥间隔时间、氮、磷、钾施肥量对苗木的高、地茎、根冠比、壮苗指数的影响进行较全面探讨,研究野漆树轻型基质工厂化育苗的科学施肥技术。结果表明:施肥间隔对苗高、地茎、根冠比、壮苗指数都有极显著影响,尿素、过磷酸钙、氯化钾的使用量对苗高、地茎、壮苗指数有极显著影响,而尿素、过磷酸钙、氯化钾的使用量对根冠比的影响差异不显著。在育苗施肥过程中,施肥越勤,苗高越高,地茎越粗,根冠和壮苗指数越大,且有最佳的施肥间隔时间和最佳施肥量。经模拟寻优,最佳施肥方案是当在100kg水中加入尿素、过磷酸钙、氯化钾分别为0.826、2.122、1.696kg,每隔9天浇施1次,施肥效果最佳。
In order to systematically study the matrix field planting seedlings of light lacquer technique, with 4 factors, 3-level orthogonal design, the effects of the time interval by fertilization, nitrogen, phosphorus and potassium fertilizer on the seedling high, to stem, root to shoot ratio, seedling index were studied. The results showed that： fertilization interval of height, to stem, root to shoot ratio, seedling index had a very significant impact, urea, superphosphate, potassium chloride on the use of seedling height, ground stems, seedling index had significant effects, while urea, superphosphate, potassium chloride, the use of the impact of root to shoot ratio was not significant. The process of fertilization in the nursery, fertilization more frequently, the higher the height, to the more coarse stems, shoot and seedling index the greater the interval of fertilization and the best time and best fertilizer. The simulation optimization, optimal fertilization program was added to the water when 100 kg of urea, superphosphate, potassium chloride, respectively 0.826, 2.122, 1.696 kg, once every 9 days pouring a times to seedlings, this fertilization was the best.
