| 摘 要： | 通过田间试验,研究了优质烤烟生产灌溉技术的一些必要参数。结果表明:叶温差与土壤相对含水量关系密切,可以作为烤烟水分亏缺指标,用以指导灌溉;叶温差的变化与叶片萎蔫情况相对应,可用叶片的萎蔫情况来估计叶温差,适用于指导烟农灌水;在旺长前期、中期及成熟前期各灌水1次,旺长期每次灌水量为4kg/株,成熟期为2kg/株。 |
| 关 键 词： | 烤烟 灌溉时期 灌溉方式 灌溉数量 |

| Abstract: | Through the field test,some essential parameters on high quality flue-cured tobacco production irrigation technology were studied.The results showed that the leaf temperature difference was closely related with the soil relative moisture content,which could be used as the lack target of the flue-cured tobacco moisture content to instruct the irrigation.The change of leaf temperature difference was correspond to the leaf blade wilting situation,and this was helpful to estimate the leaf temperature difference to instruct irrigation.Irrigating should be done once respectively in earlier and middle period of vigorous growing stage and ripe earlier stage.The pouring water amount in vigorous growing stage was 4kg/plant each time,and 2kg/plant in mature period. |
| Keywords: | flue-cured tobacco irrigations stage irrigation method irrigation amount |
