为探索内置小棚膜技术的实际增温效果,选取重庆市武隆县和顺镇青木池育苗工场内完成内置小棚膜技术改造的育苗池为试验对象,通过设置不同的揭/盖膜时间组合、不同的育苗池水深度对漂浮育苗环境温度的影响因素进行了研究。结果表明:1)内置小棚膜技术改造对增加棚内环境温度有较为显著的效果,但不同揭/盖膜时间组合对小棚内环境温度保持无显著影响。2)不同揭/盖膜时间组合对小棚内温度动态变化的影响差异并不显著。相对而言,T4处理(揭膜12:30+盖膜15:30)在小棚内微环境温度的保持上表现出略微优势。3)不同池水深度对小棚内增温效果的影响各不相同,随池水深度的增加(或减少)未表现出非常明显的规律,但池水深度为11cm时,小棚内的微环境温度相对较高。4)育苗池小棚内环境温度的垂直空间分布规律表现为水下垂直空间的积温普遍高于水上垂直空间积温,且大致呈现出离水面越近温度越高的趋势。
In order to explore the actual warming effect of the built-in small-shedding membrane technology, the nursery pond with built-in small-shedding membrane technology was completed in Qingmuchi nursery plant of Heshun Town, Wulong County, Chongqing Municipality as the test object. By setting different combinations of exposing / , The influence of different water depth of nursery pond on the environmental temperature of floating nursery was studied. The results show that: 1) The technical transformation of the built-in small-shed film has a significant effect on increasing the temperature of the inside of the shed. However, the combination of different times of exposing and covering film has no significant effect on the ambient temperature in the shed. 2) The effect of different exposures / capping time combinations on the dynamic changes of temperature inside the shed is not significant. In contrast, the T4 treatment (Closure 12:30 + Lid 15:30) showed slight advantages in maintaining the microenvironmental temperature in the canopy. 3) The effects of different water depths on the warming effect in the canopy are different, and no obvious rule is found with the increase (or decrease) of the water depth. However, when the water depth is 11cm, the microenvironment temperature in the canopy is relatively Higher. 4) The vertical spatial distribution of ambient temperature in nursery ponds showed that the accumulated temperature in vertical space was generally higher than the vertical temperature in water, and the temperature near the water surface was approximately the same.
