摘要
为了提高烟苗的素质 ,在聚乙烯塑料托盘上 ,用猪粪渣、河沙、大田本土作为不同基础材料配方进行烤烟假植育苗的研究 .结果表明 ,以 5 0 %猪粪渣加 5 0 %河沙处理的烟苗素质最佳 ,其次是 5 0 %猪粪渣加 5 0 %大田本土的处理 ,这两种处理的烟苗素质均优于稻草圈假植苗 ,达到了壮苗标准 .托盘假植苗的适栽苗龄为 15～ 2 0 d,移栽大田后 ,比稻草圈假植苗单株有效叶数增加 0 .8片 ,产量增加 5 .0 % ,产值提高 5 .1% ,育苗成本降低 6 0 % ,纯收入增加 8.2 % .
Plastic plate heeling in for flue cured tobacco was studied by using different basic materials.The results show that the best quality of seedling is obtained from the culture base composed of 50% pig feces plus 50% sand,while the second best is from the treatment of 50% pig feces plus 50% field soil.Seedling quality of the two treatments are superior to that in straw pot,and both attain strong seedling standard.The suitable planting seedling age of plastic plate heeling in is 15~20 days.After planting,effective leaves per plant increase by 0.8 piece;output increases by 5.0%;output value rises by 5.1%;seedling cost reduces by 60.0%;pure economic efficiency increases by 8.2% when compared with that in straw pot.
