新型生物有机肥对烤烟生长的影响
Effects of New Bio-organic Fertilizer on Growth of Flue-cured Tobacco
摘要
Abstract
This study aims to analyze the effects of a novel biological organic fertilizer on tobacco cultivation,specifically its regulatory impact on the growth and development of flue-cured tobacco plants.A pot experiment was conducted to study the impact of five treatments on root indicators,agronomic traits,and biomass of flue-cured tobacco.The treatments included tobacco-specific compound base fertilizer(CK),tobacco-specific compound base fertilizer with composted organic fertilizer(O),tobacco-specific compound base fertilizer with microbial agents(M),tobacco-specific compound base fertilizer with ordinary microbial fertilizer(BOF1)and tobacco-specific compound base fertilizer with novel biological organic fertilizer(BOF2).At vigorous growth stage,the stem diameter,maximum leaf length,maximum leaf width and SPAD value of the two bio-organic fertilizer treatments were significantly higher than those of the other treatments(P＜0.05).The root length of each treatment showed the order of BOF2＞BOF1＞O＞M＞CK,the order of root surface area was BOF2＞O＞BOF1＞CK＞M(P＜0.05).The total fresh weight,shoot dry weight and total dry weight of flue-cured tobacco in BOF2 treatment were significantly higher than those in other treatments.At the early maturity stage,the plant height,stem diameter,maximum leaf width and SPAD value of BOF2 treatment reached the maximum value,and the fresh and dry weights of aerial parts were also the highest,which were 44.95％and 61.31％higher than those of CK.The correlation analysis showed that the root morphology of flue-cured tobacco was significantly correlated with the maximum leaf length,the number of effective leaves and the fresh weight of aboveground parts.Compared with the other treatments,the new bio-organic fertilizer significantly improved many agronomic traits of flue-cured tobacco,increased the growth rate of root system at early stage,enhanced the dry matter accumulation of aboveground and underground parts,and promoted the growth and development of flue-cured tobacco.关键词
