一、控制放苗密度笔者从近年广西、广东和海南三地南美白对虾养殖中发现,广西地区养殖成功率明显高于其余两地。其主要原因之一是广西地区放苗密度比其余两地小,广西地区通常每亩普通精养池放苗3万～5万尾。而广东斗门区平均放苗12万尾以上。放苗密度不同,效益也不同。少放苗者 First, the control of seedling density The author from Guangxi, Guangdong and Hainan in recent years, three white shrimp farming found that the success rate of breeding Guangxi was significantly higher than the remaining two places. One of the main reasons is that the density of Fangmiao seedling in Guangxi is smaller than that of the other two. Guangxi usually has 30,000 ~ 50,000 turtle seedlings per mu in general intensive ponds. Doumen District, Guangdong, an average of more than 120,000 Fangmiao. Fangmiao different density, efficiency is also different. Fewer people put Miao
