河蚌育珠是一条致富的好门路。只要切实掌握其技术要领,就完全能够获得理想的经济效益。一、水域的选择与培肥育珠水面大小不限,但以5～10亩最佳。要求水源充足、溶氧量高,生物饵料丰富,并具备流速为每分钟5～6米的流水条件。水深以2米左右为宜。底质以砂壤土为好,淤泥不能超过10厘米。无机盐类养分丰富,钙质含量要求在10毫克/升以上。水色黄褐色,透明度30厘米左右。无工业污水流入,酸碱度以中性为宜。选择到适宜的水域后,必须根据季节进行施肥,以培肥水质。春季,在投蚌前施足底肥,以有机肥为主,投蚌后追肥随水温的逐步上升,逐渐增加用肥,
River clam Yu Zhu is a good way to get rich. As long as they effectively grasp the technical essentials, they are fully able to obtain the desired economic benefits. First, the choice of water and fertilization Pearl water surface is not limited to the size, but the best 5 to 10 acres. Requires adequate water, dissolved oxygen high, rich biological feed, and have a flow rate of 5 to 6 meters per minute of water conditions. Depth of about 2 meters is appropriate. Sediment of sandy loam as well, the sludge can not exceed 10 cm. Inorganic salts rich in nutrients, calcium content requirements above 10 mg / l. Aqua color brown, 30 cm or so transparency. No industrial sewage inflow, pH is neutral. After selecting the suitable water area, fertilizers must be applied according to the season so as to cultivate water quality. In spring, before applying the base fertilizer, the main fertilizer is organic fertilizer. After dressing the clam, the top dressing will gradually increase with the increase of water temperature,
