目前,临沂烟区主要以人工浇穴和灌沟等灌溉方式进行烟田抗旱,虽在一定程度上缓解了烟田旱情,但此灌溉方式存在劳动强度大、成本投入高、抗旱效果持续性差等问题,且大水漫灌抗旱方式水分利用率较低,造成了灌溉水资源的大量浪费。与传统灌溉方式相比,节水灌溉具有省工、节水、减轻烟田板结、防治烟叶灼伤、提高烟叶产质量等优点。该研究通过对喷灌、滴灌两种节水灌溉方式进行直观评价,验证新型灌溉方式对烤烟生长的影响及减工降本效果,为下一步节水灌溉技术在临沂烟区的推广提供技术参考和理论依据。
At present, Linyi tobacco-growing areas mainly use artificial irrigation and irrigation ditches to control drought in tobacco fields. Although it has alleviated the drought in tobacco fields to a certain extent, this irrigation method has the characteristics of labor intensity, high cost and poor durability. Problem, and the water use efficiency of flood control and flood control is lower, resulting in a lot of waste of irrigation water resources. Compared with the traditional irrigation methods, water-saving irrigation has the advantages of saving labor, saving water, reducing the compaction of tobacco fields, preventing and curing tobacco leaf burns, and improving tobacco yield and quality. The study evaluated the effects of the new irrigation modes on the growth of flue-cured tobacco and the effects of labor reduction and cost reduction through the visual evaluation of two kinds of water-saving irrigation methods of sprinkler irrigation and drip irrigation, and provided technical reference for the promotion of water-saving irrigation technology in Linyi tobacco area in the next step. Theoretical basis.
