Result The embryonic development of Silnrus asotus in Dongting Lake was divided into 7 stages, namely, blastoderm stage, cleavage stage, blastula stage, gastrula stage, neurula stage, organogenesis stage and pre-hatching stage.

结果］洞庭黄鲶的胚胎发育过程可分为胚盘期、卵裂期、囊胚期、原肠期、神经胚期、器官形成期和出膜期7个阶段。

The endurance abilities of the embryos of sea perch, flounder and turbot at different developing stages to vitrification solutions were studied. The result showed that sea perch at tail-bud stage, heart-beating stage and pre-hatching stage had more endurance abilities to VSD2, flounder at 4-5 somites, 16-20 somites and tail-bud stage had more endurance abilities to PM3, and turbot at 4-5 somites, 16-20 somites and tail-bud stage had more endurance abilities to PMP1. The feasible equilibration time of three marine fish embryos in vitrification solutions was determined, which guided the dealing process before freezing.

对花鲈、牙鲆、大菱鲆三种鱼类不同时期胚胎分别在玻璃化液中的适应性进行了研究，发现花鲈尾芽胚、心跳胚和出膜前期胚对VSD2的耐受能力较强；牙鲆4-5以肌节胚、16-20对肌节胚、尾芽胚对PM3的耐受能力较强，大菱鲆4—5对肌节胚、16—20对肌节胚、尾芽胚对PMP1的耐受能力较强，较适合于进行玻璃化液处理和冷冻保存；并且确定了三种鱼类各时期的胚胎在玻璃化液中的适宜平衡时间，为胚胎在玻璃化液中处理和冷冻提供了一定的参数。

In detail, the lost percentages of N2 applied at the stage of spring maize sowing and two nitrogen level applied at pre-tasselling stage of spring-sown maize exceeded 40%, among them the lost percentage of N1 applied at pre-tasselling stage was highest.

同时，春玉米播种时底施N2和春玉米大口期追施的N1、N2氮的损失率均大于40％，其中春玉米大口期追施的N1时的损失率最高。
