Influence of applying BGA conditioner on growth of sugarcane seedling

【Objective】 The experiments aimed to study the growth effect of the BGA soil conditioner on sugarcane at seedling stage in different soil types so that relevant information could be provided for applying BGA soil conditioner in sugarcane production.【Method】 Outdoor pot-culture trial was designed for two types of soil(loam and clay),two varieties(Guitang 02-281 and ROC22),and four BGA treatment levels(B1,B2,B3,B4 with 2,4,6,8 g BGA/kg soil,respectively) with CK1(blank control) and CK2(1.2 g compound fertilizer/kg soil control).Then chlorophyll content,plant height and nutrient content in leaves at sugarcane seedling stage were measured in varied treatments.【Result】 Under pot experiment,BGA soil conditioner could promote the growth of sugarcane seedling,increase chlorophyll content and plant height,improve nitrogen and potassium content of sugarcane leaf significantly.The effect of BGA treatment in clay was evidently better than in loam,but the effect was similar between the two varieties in the same soil.Meanwhile,the best effect was achieved in 6 and 8 g/kg BGA.【Conclusion】 BGA soil conditioner can stimulate the growth of sugarcane seedling in pots.
