摘要
塑料大棚充气培育早茬虾苗,每亩放养体长0.7cm虾苗1000万尾以上,培育20天左右出棚,虾苗平均体长1.62cm,成活率50%左右,两年平均每公顷创利250575元。1992年11月专家鉴定认为,本技术达到国内先进水平。
A batch of the early-bred prawn larvae was reared in the oxygenating pond with the bigplastic shed. The releasing density Per mu (0. 0667 hectare) was 10 million odd larvae of 0. 7cm inlength. After rearing 20 days the average they length of larvae reached 1. 62cm and the survival ratewas 50%. The profit Per ha was 250 575 yuan. The technique, appraised by experts concerned inNov. 1992,has met the advanced standard in China
