Across joins 2 be: Both sides makes alternate connection, mutual promotion opposite party needs the keyword of promotion, if A B C D stands, a B station is my site, c D station is site of the other side, it is me above all with A the station puts join of station of C of the other side, the other side joins with D station my B stands, such quality that makes the A station that the condition is me asks like Pr and the condition of the D station of the other side is a balance, such we just make connection significant, simple for the rank that such purpose is the C station that we popularize him in side the other side, the other side is popularizing the rank that our B stands, be mutual benefit actually, a lot of had not become alternate connective friend, should turn to them a little only next turns, they are muddleheaded, it is a dot really so it is cerebrum begins god-given report, but the result that such doing is very fast, the result that compares direct trade is good, because search engine to like one-way link, such rank is collected what come is fast, most stationmaster feels to inquire inconvenience so, what such doing is easy let stationmaster consider as cheating join, because such inquiry is no-go, unlike straight contact joins into the other side the connection that can see he stands is checked easily, anyway aught has the one side of its advantages and disadvantages!

交叉连接二是：双方都做交叉连接，互相推广对方需要推广的关键词，如 A B C D 站，A B 站是我的站点， C D站是对方站点，首先是我用A站放对方C站连接，对方用D站连接我的B站，这样的做条件是我的A站的质量如pr要求和对方的D站的条件是平衡的，这样我们才做连接有意义了，简单来说这样的目的是我们在帮对方推广他的C站的排名，对方在推广我们的B站的排名，其实都是互利的，好多没有做过交叉连接的朋友，只要稍微给他们转下弯，他们就糊涂了，这样的确是点是大脑开始难得反映，但是这样做的效果很快，比直接交换的效果好，因为搜索引擎喜欢单向连接，这样的排名收录都来的快，大多数站长觉得这样查询不方便，这样做的容易让站长认为是在骗连接，因为这样的查询是不方便，不像直接点进对方连接能看见自己站的连接容易检查，反正任何事物都有它的利弊的一面吧！

It is conducive to uptake soil nitrogen for flue-tobacco on dryland soil with maize-tobacco rotation before topping (60 days after transplanting) and uptake soil nitrogen for flue-tobacco on paddy soil with rice-tobacco rotation after topping.2 The nitrogen utilization efficiency of rapeseed cake, rice straw and rape straw were 19.5%, 15.5%, 8.1% respectively, and the inorganic fertilizer nitrogen utilization efficiency were 41.1%, 42.7% and 35.7% under the combined application of organic additives and inorganic nitrogen fertilizer. The contribution rate of rapeseed cake, rice straw, rape straw to accumulated nitrogen of flue-cured tobacco were 1.0%, 2.4%, 2.7% respectively by the combined application of organic additives and nitrogen fertilizer. Flue-cured tobacco for organic nitrogen absorption meet with the nitrogen needs laws of high-quality tobacco, indicating that the combined application organic additives and inorganic nitrogen fertilizer reduces the nicotine content of tobacco, an increase of sugar/nicotine ratio and improved the quality of tobacco. In which the role of rice and rape straw is greater than the rapeseed cake can be used as measures to lower nicotine.3 Nitrogen accumulation in flue-cured tobacco with the total nitrogen input was a significant positive correlation during the growth stage of flue-cured tobacco. The total nitrogen input for the 156.3-405.5kg.hm-2, in which the soil nitrogen mineralization capacity account for 22.6%-54.3%, with an average of 34.5%, that is, soil nitrogen mineralization accounted for 1/3 of the total nitrogen input.
