一、做好防暑降温工作。稻田中的水温在盛夏期常达39℃左右,已超过田鱼的致死温度。解决的办法是:在鱼溜或鱼坑上,用稻草等物搭一个凉棚,当气温较高时,则将田鱼赶入鱼溜或鱼坑避暑。如果发现水温高达35℃以上时,应立即加大水深或换入新水,直到鱼类活动正常为止。二、处理好水稻浅灌、烤田与养鱼的关系。一是将丰产沟或鱼沟适当加深加宽,以扩大鱼的生存空间;二是根据各地实际和稻田大小,增加鱼溜或鱼坑的数量。
First, do a good job in summer cooling. The water temperature in paddy fields is about 39 ℃ in midsummer, which has exceeded the lethal temperature of field fish. The solution is: in the fish slides or fish pits, with straw and other things to take a pergola, when the temperature is high, then the field fish into the fish slipper or fish pit summer. If you find that the water temperature is as high as 35 ℃ above, you should immediately increase the depth of water or change into new water until the fish activities are normal so far. Second, deal with rice shallow irrigation, grilled fields and fish relations. One is to broaden or broaden the harvesting ditches or fish ditch to broaden the living space of the fish. The second is to increase the number of fish slides or fish pits according to the actual situation and the size of the paddy fields.
