不同垄作措施与烤烟生长研究 Ⅰ对农艺性状及产量的影响

Effects of different raised bed on flue-cured tobacco growth Ⅰ affecting the agronomic traits and produces

通过田间试验研究不同垄作措施对土壤部分物理性状和烤烟生长及产值的影响。结果表明,不同垄作措施对土壤温度、水分及烤烟产量、产值的影响差异显著。在各处理中宽垄揭膜处理对保持垄体水分最明显,相同时期最高差值比对照高16.52%;对土壤温度的影响则以高垄揭膜处理较为显著,高于对照的最大差值为14.74%。最终对烤烟的经济指标和产值的影响则是高垄不揭膜处理最显著,比对照提高26.92%;其次为宽垄不揭膜,揭膜处理的高垄和宽垄反而不及不揭膜所对应的处理。

The effects of different raised bed measures have been studied on soil partial physics character and flue-cured tobacco growth. The results showed that the effect of different raised bed measures was remarkable on the soil temperature, the moisture content, the flue-cured tobacco output and production value. The effect of wide ridge with transplanting film was remarkable on the soil moisture,the maximum differential value was 16. 52% compared with control in the same period. The effect of high ridge with transplanting film was remarkable on the soil temperature, the maximum differential value was 14. 74% compared with control. The effect of high ridge with covering film was remarkable on the economic indicatorand produces,it increased 26. 92%. The wide ridge with covering film was the second. The transplanting film was inferior to covering film.
