本文根据一九八二年在本所试验塘与南县乌咀公社渔场的试验的考查分析,同时对华容县操军公社渔场和汉寿县水科所的高产试验塘进行初步调查,试图将这四种类型的池塘的生产性能作粗浅的剖析,以探讨提高池塘生产力的途径。一、池塘的生态类型与生产性能本所试验塘面积5.1亩,水深2.2米,属多年老塘,污泥30公分厚,间有外源肥水,乌咀池塘一九八○年新建,200亩共13口,水深平均一米,缺排灌设施,操军池塘也为一九八○年投产,200亩共18口,水深平均1.8米,排灌方便,汉寿水科所池塘178亩共
Based on the test and analysis of the fishing grounds in Tiantang and Wu County Commune of Nanxian County in 1982, the paper also conducts a preliminary investigation on the high-yielding pilot pond of Fisheries Farm of Huarong County and Hanshou County Water Science Bureau, The production performance of these four types of ponds is superficially analyzed to explore ways to increase pond productivity. First, the ecological type of ponds and production performance of the experimental pond area of 5.1 acres, 2.2 meters deep, is a multi-year old pond, sludge 30 cm thick, between the exogenous fertilizer, Wuxui pond newly built in 1980, 200 acres A total of 13, the average depth of 1 meter, lack of irrigation facilities, operation of military ponds also put into operation in 1980, a total of 18 acres of 200 acres, an average of 1.8 meters deep water, irrigation and drainage convenience,
