素旺BB肥对甘蔗生产的影响

Application of Suwang BB Fertilizer in Sugarcane Production

为充分了解和评价不同类型肥料在甘蔗生产中的施用效果,探索在等价投入前提下,各参试肥料对甘蔗单产及品质的影响,找出能使甘蔗增产增糖又能使甘蔗地土壤理化性质得到改善的肥料类型,设计2个不同类型肥料(即BB肥与常规复合肥)进行比较试验。结果表明:新植蔗,施用BB肥时,螟虫平均为害率降低了0.41%(绝对值,下同),单产平均增加了5.10%;宿根蔗,施用BB肥时,螟虫平均降低则为0.94%,单产平均增加15.68%,整体表现都优于施用普通复合肥;在甘蔗品质分析方面,无论新植还是宿根,蔗糖分均有所降低,新植蔗纤维分平均增加了0.35%,但宿根蔗则减少0.68%。本试验条件下,施用BB肥甘蔗产量略高于复合肥,但对甘蔗品质与BB肥的关系有待进一步研究。

In order to fully understand and evaluate the application effects of different types of fertilizers insugarcane production,explore the effects of various tested fertilizers on the yield and quality of sugarcane underthe premise of equivalent input,and find out the fertilizer that can increase the yield of sugarcane and sucrosecontent and improve physical and chemical properties of the soils,two different types of fertilizers(BB fertilizerand conventional compound fertilizer were selected to conduct a comparison experiment.The experiment resultsshowed that the average borer damage with BB fertilizer application decreased by 0.41%(absolute value)andaverage cane yield increased by 5.10%compared with conventional compound fertilizer in new-plant crop;theaverage borer damage with BB fertilizer application decreased by 0.94% (absolute value)and average cane yieldincreased by 15.68% compared with conventional compound fertilizer in ratoon crop.The sucrose contentdecreased a little bit in both new-plant and ratoon when applying bb Fertilizer.The fiber in cane increased by 0.35% in New-plant crop and decreased by0.68%in ratoon.Under this experiment conditions,BB fertilizer canincrease cane yields but the effect in sugarcane quality needs further study in future.
