烤烟施用畜禽粪便商品有机肥的效应
Effect of Livestock and Poultry Manures on Production of Flue-cured Tobacco
-
摘要: 为探索畜禽粪便商品有机肥在烤烟生产中的效果,通过大田试验研究了该肥料对烤烟生长发育及产质量的影响。结果表明,施用该有机肥大部分处理烟株的团棵期推迟,各处理烟株的腰叶、顶叶成熟期基本相同;施用有机肥处理的株高高于烟草专用肥处理;大部分施用有机肥处理的平均有效叶数比烟草专用肥处理多1~2.7片/株;施用猪粪和牛粪的有效叶数比鸡粪的多;处理间的产量差异未达显著水平;猪粪1、猪粪2处理的产值比饼肥处理和专用肥处理的略高,但差异未达显著水平,牛粪和鸡粪3处理的产值最低;施用畜禽粪便有机肥烟叶的香吃味与施用饼肥的烟叶无实质性区别,烤烟生产可大面积应用畜禽粪便商品有机肥。Abstract: Livestock and poultry manures were applied largely in agricultural production. Field experiments were conducted to explore the effects of livestock and poultry manures on flue-cured tobacco production. The result showed that the manure application delayed the resettling stages of flue-cured tobacco, but did not influence the mature stages of lumbar or uppermost leaves. Plant was higher in the manure treatment than those in common tobacco fertilizer treatment. The manure treatment increased the number of effective leaves 1-2.7 leaves per plant. The effective leaves were more for the treatments with pig or cattle manure than those with chicken manure. However, it was not significant for the tobacco yields among the treatments. The output values of the treatments with pig manure no. 1 and no 2 were slightly, but not significantly, higher than with cake fertilizer or common fertilizer. No significant different on tobacco flavor was observed between livestock and poultry manures and cake fertilizer treatments.
