| 摘 要： | 目的]为优化利用黔东南州烤烟气候资源.方法]开展不同孔深度试验（15、19、23 cm）、不同孔口大小试验（10、12、14 cm）、不同打透气孔时间试验（不打透气孔、移栽后立即打透气孔、顶叶顶膜或气温到20℃后打透气孔）、不同时间破膜试验（顶叶距地膜1 cm破膜、顶叶顶膜破膜、心叶距地膜1 cm破膜）、不同施肥试验（基追比7∶3且追肥分别于封土和揭膜上厢时进行施用、基追比7∶3且追肥于揭膜上厢时期一次施用、基追比6∶4且追肥分别于封土和揭膜上厢时进行施用、基追比6∶4且追肥于揭膜上厢时期一次施用）等膜下移栽配套技术研究.结果]孔深度以19 cm利于烟株生长,过深烟苗较难长出垄面,过浅很难体现膜下移栽的效果;孔口大小为12 cm时较适宜烟苗早生快发,过小孔内湿度较大,过大保温差;移栽后立即打透气孔利于晴天孔内透气、降温,并使烟苗逐步适应外界环境,加快烟苗生长;心叶距地膜1 cm时及时破膜好于其他两个处理;追肥于封土和上厢时施用好于其他处理,烟株长势均匀且较快.结论]该研究可为建立烤烟膜下移栽技术体系提供理论支撑.

| Abstract: | Objective] The aim was to optimize and utilize climate resources of flue-cured tobacco in The Southeast of Guizhou Province.Method] The film-under transplanting supporting technology researches,such as different hole depth test（the designed hole depth was 15,19,23 cm respectively）,different orifice size test（the designed hole size was 10,12,14 cm respectively）,different punched air hole time test（the designed punched air hole time was no punching,immediately after transplanting,and when the top leaf burst membrane or the temperature was up to 20 ℃,respectively）,different bursting membrane time test（the film was burst when the distance from the top leaf to the film was 1 cm,the top leaf burst the film,the the film was burst when the distance from the heart leaf to the film was 1 cm,respectively）,different fertilization test（the ratio of basic fertilizers to supplement fertilizers was 7∶3,and the supplement fertilizers were used at covering soil and uncovering film ; the ratio of basic fertilizers to supplement fertilizers was 7∶3,and the supplement fertilizers were used at uncovering film only; the ratio of basic fertilizers to supplement fertilizers was 6∶4,and the supplement fertilizers were used at covering soil and uncovering film ; the ratio of basic fertilizers to supplement fertilizers was 6∶4,and the supplement fertilizers were used at uncovering film only,respectively）,were carried out.Result] 19 cm-hole depth was favor of tobacco seedlings growing,if the hole was too deep tobacco seedlings were harder to grow ridge surface,while if the hole was too shallow tobacco it was hard to reflect the effects of film-under transplanting; 12 cm-orifice size was suitable for tobacco seedlings coming out early and quickly,too small made the humidity in hole was bigger,while too big had worse heat preservation effect ; that punched air hole after transplanting was favor of ventilation and decreasing temperature in hole,and made tobacco seedlings adopted to the external environment gradu |
