A two-year field experiment was conducted to investigate ammonia volatilization from Gleyed paddy soil in the Taihu Lake region. The experiment was designed to have four N levels 0, 180, 255, 330 kg hm^(-2 and four P205 levels 0, 30, 90, 180 kg hm^(-2, forming six NP combinations (CK-N0P0, LN-N180P90, OPT-N255P90, LP-N255P30, HP-N255P180 and HN-N330P90). Ammonia volatilization was measured with the enclosure method.

The probing behaviors of the tea green leafhopper, Empoasca vitis Gothe, on nine tea cultivars were studied by videotext Direct Current-Electrical Penetration Graph, i. e. DC-EPG. Following seven types of waveforms produced by the leafhopper stylet probing were determined: A, stylet pathway formation; S, salivation when stylets pierce into and stay in phloem; C, active ingestion before stylets reach phloem; E and F, passive ingestion in phloem; R, the insect resting with its stylet inserted into the leaf tissue and NP, not probing.

应用可视DC-EPG方法研究了假眼小绿叶蝉在9个品种茶苗上的口针刺探行为，共发现并初步确定了7种主要波型，即A波、S波、C波、E波、F波和R波、以及非刺探波NP波。A波为刺探波，S波为口针向韧皮部刺探和进入韧皮部中的分泌唾液波，C波为口针到达韧皮部之前的主动取食波，E波和F波为口针在韧皮部中吸收波，R波为取食间歇波。
