摘要
针对云南烟区烟草漂浮育苗用水情况开展调查,为提高水资源利用率及促进育苗方式的发展和改进提供理论依据。采用询问、走访、实地考察的方式,选取云南省10个市(州)典型植烟区育苗基地进行调查,分析并明确影响漂浮育苗用水效率的因素。结果表明,调研区域有用于膜下小苗移栽(小苗)和常规移栽(大苗)的两种成苗规格,总用水量和烟苗耗水量分别为311.74 kg/m^(2)和216.48 kg/m^(2)、374.53 kg/m^(2)和248.64 kg/m^(2),且在育苗过程中存在99.48 kg/m^(2)的无效用水,占平均总用水量的31.05%;用水效率方面,楚雄州最低,玉溪市最高;小苗育苗用水效率与苗盘规格呈显著负相关,大苗育苗用水效率与经度呈显著负相关;不同烟区育苗用水量存在差异,育苗点经度、苗池面积和苗盘规格是影响育苗用水效率的重要因素。小苗育苗用水量明显低于大苗,小苗育苗采用较小的苗盘规格可提升育苗用水效率,大苗育苗的用水效率与苗盘规格、苗池面积等因素呈正相关。
In order to provide a theoretical basis for improving the utilization rate of water resources and promoting the development and improvement of seedling raising methods,the water consumption of tobacco floating seedling in Yunnan tobacco area was investigated.By means of inquiry,visit and on-the-spot investigation,the seedling raising bases in typical tobacco planting areas of 10 prefectures and cities in Yunnan Province were selected for investigation,and the factors affecting the water use efficiency of floating seedling raising were analyzed and clarified.The results showed that,there were two seedling specifications for transplanting seedlings under film(small seedlings)and conventional transplanting(large seedlings)in the survey area.The total water consumption and water consumption of tobacco seedlings were 311.74 kg/m^(2)and 216.48 kg/m^(2),374.53 kg/m^(2)and 248.64 kg/m^(2),respectively,and there was 99.48 kg/m^(2)ineffective water in the process of seedling raising,accounting for about 31.05%of the average total water consumption.In terms of water use efficiency,Chuxiong base was the lowest and Yuxi base was the highest.The water use efficiency of small seedlings was significantly negatively correlated with the size of the seedling tray,and the water use efficiency of large seedlings was significantly negatively correlated with longitude.There were differences in seedling water consumption in different tobacco areas;the longitude of the seedling point,the area of the seedling pool and the size of the seedling tray were important factors affecting the efficiency of the seedling water use.The water consumption of small seedlings was obviously lower than that of large seedlings.The water use efficiency of small seedlings could be improved by using smaller seedling tray specifications.The water use efficiency of large seedlings was positively correlated with seedling tray specifications,seedling pool area and other factors.
