Abstract: In order to explore the practicability of the film photovoltaic engineering culture mode, the experiment on culture of Litopenaeus vannamei was carried out in the film photovoltaic engineering culture system, which consisted of shrimp culture system and photovoltaic power generation system. The experiment on high density culture of L. vannamei was conducted in three ponds, with stocking density of 500 shrimps/m2 and culture experiment cycle of 100 d. The average body length of L. vannamei was (9.77 ± 0.11) cm, and the average body weight was (10.80 ± 0.82) g. The yield of No. 1 pond was 4.25 kg/m2, the survival rate was 78.71%, and the feed coefficient was 1.22. The yield of No. 2 pond was 4.42 kg/m2, the survival rate was 81.85%, and the feed coefficient was 1.18. The yield of No. 3 pond was 4.07 kg/m2, the survival rate was 75.37%, and the feed coefficient was 1.25. During the culture, the range of water temperature at 08:00 and 15:00was 22.5~31.0 ℃ and 22.5~32.0 ℃ respectively, with maximum daily air temperature difference of 11.0 ℃ and maximum daily water temperature difference of 2.5 ℃, the pH was stable between 7.00 and 8.34, and the concentration range of nitrite nitrogen (NO2--N ) and total ammonia nitrogen (TAN) was 0~8.47 mg/L and 0~7.83 mg/L respectively. The film photovoltaic engineering culture of L. vannamei has realized the double benefits of shrimp culture and photovoltaic power generation, which has great practical value and is worth popularizing.

摘要： 为研究地膜光伏工程化养殖模式的实用性，在地膜光伏工程化养殖系统中开展凡纳滨对虾养殖试验。地膜光伏工程化养殖系统由对虾养殖系统和光伏发电系统组成。取3口池塘进行凡纳滨对虾高密度养殖试验，放养密度为500尾/m2，养殖试验周期100 d。凡纳滨对虾平均体长达到(9.77±0.11) cm，平均体质量(10.80±0.82) g。1号池塘产量为4.25 kg/m2，存活率为78.71%，饲料系数为1.22；2号池塘养殖产量为4.42 kg/m2，存活率为81.85%，饲料系数为1.18；3号池塘产量为4.07 kg/m2，存活率为75.37%，饲料系数为1.25。养殖期间08:00水温范围为：22.5~31.0 ℃；15:00水温范围为：22.5~32.0 ℃，日气温差最大为11.0 ℃，日水温差最大为2.5 ℃。养殖期间pH稳定在7.00~8.34之间。养殖期间亚硝酸盐氮（NO2--N）0~8.47 mg/L，总氨氮(TAN)0~7.83 mg/L。地膜光伏工程化养殖模式养殖凡纳滨对虾，实现了对虾养殖和光伏发电的双重收益，具有较大的实用价值，是一种值得推广的养殖模式。
