1999年至2000年,广西组织实施了农业部“对虾健康养殖高产技术”丰收计划项目。对虾养殖面积16360亩,总产量3522308公斤,单产215.3公斤,平均亩产值12918元;投入产出比1:2.56,投资收益率139.83%,取得较好的经济效益和社会效益。1 改造虾池,营造对虾生长的良好池塘环境 理想的虾池面积一般10~20亩,池深2~2.3米,水深1.5米左右。池塘面积大,水位浅,排灌不分的虾池,必须进行改造。虾池改造方法主要有:①大池改小。对面积比较大的虾池,进行筑堤分隔,改造成面积10~20亩左右的小虾池;②加深虾池,加固加高池堤。对水位比较浅的虾池,利用机械推土加深,
From 1999 to 2000, Guangxi organized and implemented the “Harvest Plan for High-yielding Shrimp Health Breeding Technology” of the Ministry of Agriculture. Shrimp farming area of 16,360 mu, with a total output of 3522308 kilograms, yield 215.3 kilograms, the average yield of 12,918 yuan per mu; input-output ratio of 1: 2.56, investment return rate of 139.83%, and achieved good economic and social benefits. 1 renovated shrimp ponds, shrimp ponds to create a good environment for growth ideal shrimp ponds generally 10 to 20 acres of area, 2 to 2.3 meters deep pool depth of about 1.5 meters. Pond area, shallow water, irrigated shrimp ponds, must be transformed. Shrimp pond reconstruction methods are: ① big pool change smaller. The larger area of the shrimp ponds, embankment separated into small shrimp ponds transformed into an area of about 10 to 20 acres; ② deepen the shrimp ponds, strengthening the pool bank. On the water level is relatively shallow shrimp ponds, the use of mechanical soil to deepen,
