本试验按每周每公顷土质鱼池分别加入125、250、500、1000公斤的固体鸡肥,连续使用5个月.每种施肥量重复3次,均有减少鱼池渗漏的效果.试验前,鱼池平均渗漏量为27～37毫米/天;施鸡肥后,平均渗漏量降至8～17毫米/天,减少54%～76%.平均渗漏损失减少量与单位施肥量之间呈正相关,差异显著(p<0.01).当在鱼池中投加1000公斤/公顷·周的鸡肥时,渗漏减少速度最快,而接近最大值的减少量出现在单位施肥量为250、500、1000公斤的第一个月;当单位施肥量为125公斤时,渗漏水量随时间成直线递减;当施肥量达到某一限值时,再增加鸡肥投入量,减渗效果也无显著提高.试验证明,1个月内每周最少施加固体鸡肥250公斤/公顷,才能有效地减少渗漏损失.连续施肥5个月,可排水干池,再次注水不会产生集中渗漏.
In this experiment, 125, 250, 500 and 1000 kg of solid chicken manure were added per hectare per hectare of soil fish pond respectively for 5 consecutive months.The results showed that each fertilization amount repeated 3 times, The mean leakage of fish ponds was 27-37 mm / day, and the average amount of leakage was reduced to 8-17 mm / day and 54% -76% after application of chicken manure. (P <0.01) .When 1000 kg / ha / week of chicken manure was added to fish ponds, the leakage rate decreased the fastest, while the decrease of near maximum reached at the rate of 250 units / 500,1000 kilograms of the first month; when the unit fertilizer amount of 125 kg, the leakage of water decreases linearly with time; when the amount of fertilizer reaches a certain limit, then increase the amount of chicken input, reducing the effect of no Significantly increased.The test proves that in a month at least a week to apply solid chicken fertilizer 250 kg / ha, can effectively reduce the leakage loss.Continuous fertilization for 5 months, drainage dry pool, re-injection of water will not produce a concentrated leakage.
