[目的]为研发适应于当地土壤和生态特色的烟草专用生物有机肥配方,并且进行配方验证和筛选。[方法]2014~2015年,在平顶山市叶县布置田间小区试验,研究不同生物有机肥对土壤氮、磷、钾、有机质含量和烟叶生长发育的影响。[结果]施用粉状有机肥配方的整体效果较差。施用解磷解钾配方的有机肥有利于烟叶前期的生长,但是在烟叶生长中后期需要及时补充钾肥。[结论]抗重茬生物有机肥不仅使得烟株的生长发育达到最优,而且减少病虫害。
[Objective] The research aimed to develop a formula for tobacco-specific bio-organic fertilizer that was adapted to the local soil and ecological characteristics, and to carry out formula verification and screening. [Method] From 2014 to 2015, field experiments were conducted in Yexian, Pingdingshan to study the effects of different biomasses on nitrogen, phosphorus, potassium, organic matter content and leaf growth and development of tobacco. [Result] The overall effect of applying powdery organic fertilizer formula was poor. Application of potassium phosphate solution of potassium fertilizer is conducive to the growth of pre-tobacco, but in the late tobacco leaves need to be promptly added potassium. [Conclusion] The anti-stubble bio-organic fertilizer not only achieved the best growth and development of tobacco plants, but also reduced the pests and diseases.
