我省除成都平原外都为丘陵或山区,其间镶嵌着无数大大小小的山塘。这些山塘的共同特点是水浅水瘦,池深1米左右,无水源保证,几乎全靠自然降雨蓄水,上半年因供农田灌溉而常致干涸,下半年雨季来到才能保持一定的水位,且形状不规则,大小不一般,塘底凹凸不平,塘坎垮塌渗漏。利用这类半年塘养鱼虽比不得精养鱼池的高产量、高效益,但只要切实抓好下述的技术措施,也能获得亩产二三百公斤鱼的收成。一、清整鱼塘,提高保水蓄水能力每年4—5月份,由于栽插秧苗的需
Chengdu except for the plains are hilly or mountainous areas, during which numerous countless large ponds. The common features of these ponds are shallow water and shallow water with a depth of about 1 meter. Without any water source guarantee, it relies almost exclusively on natural rainfall and water storage. In the first half of the year, the farmland often dries up due to irrigation. In the second half of the year, , And the shape is irregular, the size is not normal, uneven pond bottom, pond collapse collapse. Although the utilization of such semi-annual pond aquaculture fish ponds than the high yield and high efficiency, but as long as the practical grasp of the following technical measures, but also to obtain two hundred three hundred kilograms of fish per mu yield. First, clean up the ponds to improve water retention capacity 4-5 months a year, due to planted seedlings need
