抓好早春鱼塘管理,能促进鱼类提早开食,恢复体质,增强抗病能力,提高成活率。 提高水温。在适温范围内,鱼类会随着水温的上升而增加摄食、加快生长,因此,初春鱼池水位应掌握在0.6～0.8m,使水温能较快升高,以利充分发挥肥效和促使鱼类提早开食,开春后要勤灌水,对保水力差的池塘,在加注新水时,不要一次大量注入,以防水温骤降,同时应适当施些有机肥,以利提高水温。遇连续阴雨天气时,要适当增加水深,以防水温变化幅度过大。 调节水质。开春后,由于气温、水温逐渐回升,鱼类的生物饵料开始大量滋生,若发现水质老化和偏酸性,可注
Do a good job in early spring fish pond management, can promote early fish to eat fish, restore physical fitness, enhance disease resistance, improve survival. Increase water temperature. In the appropriate temperature range, fish will increase with the rise of water temperature feeding, accelerate the growth, therefore, the early spring pond water level should be at 0.6 ~ 0.8m, so that water temperature can rise faster, in order to give full play to fertilizer efficiency and to promote fish Early opening of classes of food, should be diligent irrigation after the spring, poor water retention pond, in the injection of new water, do not a large number of injection, in order to prevent sudden drop in water temperature, at the same time should be applied some organic fertilizer, to facilitate the improvement of water temperature. In case of continuous rainy weather, it is necessary to increase the depth of water, in order to prevent excessive temperature water temperature changes. Adjust the water quality. After the spring, due to the temperature, water temperature gradually picked up, the biological feed of fish began to breed, if the water quality is aging and acidic, can be Note
