All emergence index were higher markedly than control group (P.05), besides, the shrimp larvae showed high quality anduniformity, the amount of "OK" brand that was used in every group during cultivation was 48.34%,58.50%,48.81%,and 49.5% less than that of "Bonasse" brand, however, the former had the better larval nursery effect than the latter obviously. It was more recommendable that using the compound blended with formulated diet of 80% microencapsulated diets of "OK" brand and 20% rotifera than only using microencapsulated diets of "OK" brand.
另外,在培育过程中投喂欧开牌微胶囊饲料的各实验组其饲料投喂量分别比博尚牌饲料少用48.34%、58.50%、48.81%和49.5%,但其育苗效果明显好于后者。80%欧开牌微胶囊和20%卤虫配合使用培育凡纳对虾幼体的效果比单独使用欧开牌微胶囊饲料培育效果好:前者的出苗率,出苗时平均尾重,平均体长分别高出后者38.73%、利用截欢囊句料培育凡姑对炸幼体苟比软研究25%和7.8%,各项出苗指标也明显高于后者(P 。05)。

Total N increased significantly in the rhizosphere, hut total P and total K decreased. However, the available N, P and K in the rhizosphere behaved in an opposite way: with available N decreased but available P and available K increased in the rhizosphere except fur Phragmites communis Trin. Deficit of available N is the most significant, and accumulation of available P and available K were the least for Salsola nitraria Pall. among all seven halophytes.
