一、珍珠培育的水质要求 培育珍珠的水质应保持黄绿色,透明度以30cm左右为好,溶氧达到每升5毫克以上。 春季,育珠蚌新陈代谢逐渐恢复并加强,珍珠质开始沉积,此时宜施有机肥培肥水质,以加速浮游生物的繁殖。特别在4月中旬和5月上旬,是三角帆蚌性腺成熟期,又是珍珠生长期,这时育珠蚌需要大量的营养物质,要增施有机和无机肥料,使水质保持肥爽。
First, the water quality of pearls nurturing Cultivation of pearl water quality should be maintained yellow-green, with a transparency of about 30cm, dissolved oxygen to achieve more than 5 mg per liter.
