The last-named source is so subject to volatilization loss that it is never applied without soil incorporation Although commonly used in no-tillage crops, applied both at planting and as a sidedress application, some additional care must be exercised because soils tend to be wetter under no tillage and soil should be dry enough to crumble and effectively seal the slit left by ammonia application.

液氨很容易形成氨挥发损失，以至于不与土壤掺混就不能施用。虽然在免耕中也经常施用液氨，但必须特别注意，因为免耕条件下土壤比较湿润，施用时土壤必须足够干燥，使土块容易弄碎以封住施氨时留下的缝隙。

One pair of primers that amplified the gB gene of pseudorabies viruswas designed and synthesized.PCR technique detecting the DNA of PRV was established after selecting the best reaction conditions.This technique was applied to specifically amplify the 281 bp DNA fragment of the PRV strains including Fa,Fb,Bartha,BJ,GD,V2F4,S,S3,SR,Buk,Shope,Norden,Mink Ⅲ,HB,F8,F9 and F12 in cultured samples.The negative results were achieved from Vero cells,swine vesicular disease virus,hog cholera virus,Japanese encephalitis virus,porcine reproductive and respiratory syndrome virus,porcine parvovirus,foot and mouth disease virus F29 strain,O3I3 strain,T509 strain and O Ⅱ MF249 strain.The results of sequencing showed that the PCR method was of specificity.The sensitivity of PCR reached 15.8 pg of PRV Fa strain DNA.The tissue samples obtained during 1994 and 2000 were detected,and the results showed that the sensitivity of PCR was more sensitive than virus isolation and the Sandwich ELISA.The PCR was applied to detect 191 tissue samples from 31 pig farms obtained from Guangdong,Fujian,Hainan Provinces during 1999 and 2000,50 samples(26.2%)were positive and 22 pig farms(71%)were positive.
