ASP,如何转换密码

ASP,如何转换密码,第1张

用MD5加密的方式。

把用户的密码通过MD5加密后存储在数据库里,验证的时候只要把用户输入的密码用MD5加密以后与数据库里面的比较,一样就是正确的密码。

MD5源代码:

(一)永莲蜜桃系:自花结果的品种,因此,广大果农不需要进行人工授粉和配植授粉树。

(二)疏花疏果:种植桃树的目的是为了获得好的产量和收益,但为了获得好的效益必须疏果花量是很大的,几乎是需要量的9倍,1株成年的桃树,几乎80%以上的果需要疏掉,保留下来的不过20%。

永莲蜜桃为蔽开受倒春寒的影响,一般采取疏果不疏花的方法。

第一次疏果一般在落花后两周进行,疏掉果实的1/3,定果是确定当年的留果数量,定果的时间,是在完成第一次疏果之后,大约在花后5-6周进行,也就是在硬核之前结束。疏果和定果直接关系到一年的产量和果实品质,更关系到当年的收入。年以,一定要把握时机,认真 *** 作,才能获得丰产优质的果实。

(三)疏花疏果的方法:一般永莲蜜桃不需要人工疏花。疏果要先疏去双果,小果和果形不正的果。留果时,果枝所处的部位不同,留果量也不一样。树体上部的结果枝要多留果,下部结果枝要少留果,以果控制旺长,以达到均衡树势的目的,树势强的多留果,反之,则少留果。另外,定果时还要考虑果实大小。一般长果枝留2-3个果,中果枝留1-2个,短果枝留1个。弱果枝和花束状枝一般不留果,预备枝不留果,也可以根据果间距留果,果间距为15-20厘米,依果大小而定。
