，不bu僅jin提ti高gao了le池chi塘tang養yang殖zhi成cheng本ben，也ye造zao成cheng了le勞lao動dong力li的de浪lang費fei，同tong時shi也ye影ying響xiang了le池chi塘tang下xia一yi步bu生sheng產chan工gong作zuo的de進jin度du。現將春季肥水工作的難點和對策分析如下：

一、養yang殖zhi水shui體ti營ying養yang不bu足zu
，缺que乏fa藻zao類lei生sheng長chang所suo需xu要yao的de各ge種zhong營ying養yang鹽yan。往wang往wang新xin塘tang口kou和he沒mei有you施shi足zu基ji肥fei的de塘tang口kou以yi及ji使shi用yong了le非fei常chang清qing瘦shou水shui源yuan的de塘tang口kou容rong易yi出chu現xian這zhe些xie問wen題ti。此ci時shi應ying及ji時shi追zhui施shi基ji肥fei或huo使shi用yong有you益yi於yu促cu進jin藻zao類lei生sheng長chang的de生sheng物wu製zhi劑ji來lai肥fei水shui培pei育yu浮fu遊you藻zao類lei。

三、池塘底層有青苔也會抑製浮遊藻類的繁殖。方法是提高池塘水位，人工撈除，並配合底改生物製劑的使用。再追肥或使用生物肥水素。

四、大da量liang浮fu遊you動dong物wu的de持chi續xu出chu現xian也ye是shi影ying響xiang藻zao類lei生sheng長chang的de又you一yi重zhong要yao因yin素su。注zhu意yi此ci時shi不bu能neng使shi用yong藥yao物wu殺sha滅mie浮fu遊you動dong物wu，也ye不bu能neng施shi肥fei和he使shi用yong培pei藻zao類lei製zhi劑ji培pei育yu浮fu遊you藻zao類lei。對dui策ce是shi加jia強qiang水shui體ti增zeng氧yang，足zu量liang投tou喂wei飼si料liao，使shi用yong生sheng物wu底di改gai製zhi劑ji。待dai浮fu遊you動dong物wu大da量liang繁fan殖zhi到dao沒mei有you食shi物wu死si亡wang後hou，再zai進jin行xing追zhui肥fei和he使shi用yong培pei藻zao素su雙shuang管guan齊qi下xia的de方fang法fa來lai迅xun速su補bu充chong池chi塘tang藻zao類lei。
