摘要
为了降低育苗成本、实现育苗基质的可持续利用,采用苗床试验和盆栽试验相结合的方法,将腐熟的蔗渣与河砂按不同比例配置成基质,研究了其培育壮苗的效果及经济效益。结果表明,40%蔗渣+60%河砂所育出的烟苗综合性状表现较好,符合漂浮育苗壮苗标准要求。因此,利用蔗渣与河砂来替代漂浮育苗中的基质是可行的,还可以减少肥料投入,节本增效369.8元/hm2以上,经济效益和生态效益明显。
Reducing the cost of seeding and making sustainable utilization of seedling medium were the purpose of this study.Application effects of medium with different proportion of decayed bagasse and sand were studied in tobacco seedling raising in the floating system.The results showed that the comprehensive characters of tobacco seedlings were the best when the seedlings were raised with 40% decayed bagasse and 60% sand,and that the seedling fostered by this kind of medium can also meet the tobacco standards of strong seedling.Therefore,it is feasible to use decayed bagasse as a substitute in tobacco float seedling matrix and make considerable economic benefit and ecological benefit.
