不同施肥处理对容器枣苗生长的影响

Effects of different fertilization treatments on the growth of container jujube seedlings

培育无缓苗期的优质大苗对实现枣树早果速丰意义重大。采用四因素(施肥种类、施肥量、微生物菌剂用量、莽草酸施用方式)三水平的正交试验设计,研究了不同施肥处理对雨虹容器枣苗生长的影响。结果表明,影响容器枣苗生长的因素依次为施肥种类、施肥量、微生物菌剂用量、莽草酸施用方式。培育容器枣苗以在基质中施入氮、磷、钾平衡型(20∶20∶20)水溶肥料40 g/袋,微生物菌剂6 g/袋,地下浇灌莽草酸为宜。

The cultivation of high-quality seedlings without slow seedling stage is of great significance to achieving early fruit and rapid abundance of jujube trees.The effects of different fertilization treatments on the growth of’Yuhong’container jujube seedlings were studied by orthogonal experimental design of four factors(fertilizer type,fertilizer amount,microbial agent dosage and shikimic acid application method)and three levels.The results showed that the factors affecting the growth of container jujube seedlings were fertilizer type,fertilizer amount,microbial agent dosage and shikimic acid application method.The optimal conditions for container jujube seedlings were to apply nitrogen,phosphorus and potassium balanced type(20∶20∶20)of water soluble fertilizer 40 g per bag,microbial agent 6 g per bag,and underground irrigation of shikimic acid is appropriate.
