| 摘 要： | 为了探讨施用有机物料和培土覆盖措施对烤烟大田生育进程及物质积累的影响,采用大田裂区试验探讨了施用有机物料耦合培土覆盖措施下烤烟大田生育期、不同部位叶龄内不同器官干物质及氮、磷、钾积累情况。结果表明:(1)培土覆盖耦合施用14925.37 kg/hm2有机物料可缩短烤烟大田伸根期6天,分别延长旺长期、成熟期和整个生育期15、10、19天;上、中、下部位叶龄分别延长8.8、9.5、5.4天。(2)培土覆盖措施显著增加烟株有效叶片数、茎高、茎围、最大叶的长和宽以及烟株根、茎器官干物质积累;烟株根、茎和整株氮积累量,茎和叶磷积累量以及根系的钾积累量也显著增加。(3)随着有机物料施用量的增加,烟株有效叶片数、茎高、茎围、最大叶的长和宽及物质积累成增加趋势,其中施用14925.37 kg/hm2有机物料处理较不施用有机物料处理单株干物质积累平均增加0.27 kg/hm2,烟株根、茎的氮、磷以及叶片、整株的钾积累也显著增加。施用有机物料结合培土覆盖措施可有效促进烟株早生快发、优化烟株生长发育进程、延长烟株大田有效生育期和促进烟株物质积累,进而提升烟叶的田间耐熟性。

| Abstract: | In order to investigate the application of organic materials with ridge mulching measures on growth and developmental advancement, material accumulation of flue-cured tobacco during growth period. Field split plot experiment were carried out to study the effect of applying organic materials combined with hilling and mulching straw after uncovering plastic film on tobacco tobacco field growth period, leaf age and different parts of different growth stages of different organs of dry matter and nitrogen, phosphorus and potassium accumulation. The results

showed that: (1) application of 14925.37 kg/hm2 organic materials combined with earth cover measures can shorten the average root extension period 6d, and extend fast growing, maturation and the field growth stage 15d, 10d and 19d respectively, and the next, upper, middle and lower leaves age 5.4 d, 9.5 d and 8.8 respectively. (2) hilling and mulching straw after uncovering plastic film significantly increased tobacco leaf number, stem height, stem girth, length and width of tobacco leaf, root and stem dry matter accumulation, and tobacco root, stem and whole plant nitrogen accumulation of stem and leaf P accumulation and root K accumulation increased significantly. (3) with the increasing quantities of organic material, tobacco leaf number, stem height, stem girth, maximum leaf length and width and material accumulation increased, among them, the application of 14925.37 kg/hm2 organic material treatment plant dry matter accumulation increased by an average of 0.27 kg/hm2 compared with no application of organic materials, the accumulation of nitrogen and phosphorus in root and stem, potassium in leaf and whole plant tobacco increased significantly. Applying organic materials combined with hilling and mulching straw after uncovering plastic film can effectively promote the tobacco plant grow quickly , optimize the tobacco growth process effectively, prolong the growth period and promote the material accumulation of tobacco plant, and thus enhance the ripening enduring ability of tobacco leaf in field. |
