| 中文摘要: |
| 研究了南方藻种脆江蓠移植北方后进行的池塘栽培试验，试验设置了5种不同的脆江蓠池塘栽培模式，重点观测了池塘水温、盐度、pH和光照强度对脆江蓠生长的影响。结果表明，池塘水温的变化和光照强度的强弱对脆江蓠生长影响明显，本试验条件下的盐度和pH变化对脆江蓠生长影响较小。试验显示，水温20～30 ℃、光照强度＜3 000 lx、64 h池水循环1次、池塘水深3 m处底播栽培最适宜脆江蓠生长，并且栽培期间定期分苗的藻体生长速率显著高于未定期分苗的藻体。 |
| 英文摘要: |
| Five different pond cultivation patterns of Gracilaria bursapastoris were set and the effects of temperature,salinity, pH, and illumination intensity on the growth of algae were examined. The results indicated that water temperature and illumination intensity had significant influence on the growth of G.bursapastoris. The effects of salinity and pH were slight. The conditions of water temperature of 20~30℃,illumination intensity＜3,000 lx,100% water exchange per 64h,bottom sowing at a water depth of 3m were suitable for the growth of G. bursapastoris. The growth rate was greatly improved when periodical thinning was carried out. |
