硝基苯是重大污染源，一旦泄漏對生態(tài)環(huán)境及農(nóng)業(yè)生產(chǎn)以及城鄉(xiāng)居民的健康帶來嚴重威脅。研究旨在探明硝基苯對水稻育秧期的影響，為受污染威脅地區(qū)水稻生產(chǎn)提供參考。
本試驗選取當?shù)刂髟缘?span lang="EN-US">4個水稻品種作為試驗材料，以國家飲用水安全標準（0.017mg/L）為標準，設(shè)計了7個處理。試驗分為發(fā)芽試驗和秧苗試驗兩個階段。調(diào)查處理種子的發(fā)芽勢，發(fā)芽率；秧苗的株高，根數(shù)，葉片數(shù)等性狀。全部試驗在人工氣候箱和玻璃加溫室中進行。實驗結(jié)果表明：水稻育秧期水中硝基笨含量在0.051mg/L（即國家安全飲用水3倍）以下時是安全的，對秧苗生長無影響。

The nitric benzene is the graveness pollution source, once leak to produce to the ecosystem environment and agricultures and the city country the residents bring the serious threat healthily.Study the aim at explore the clear nitric benzene to the influence that the paddy rice teaches the period of , produce to provide the reference for the paddy rice that is subjected to the pollution threat region.
Experiment to select by examinations 4 paddy rices the species conduct and actions that the local lord plant to experiment the material originally, take the national drinking water safety standard(0.017 mgs/ L) as the standard, design 7 processings.Experiment to is divided into the germination to experiment to experiment two stages with rice seedling.Investigate the germination of handle the seed power, germination rate;The stub of the rice seedling is high, number, leaf's number etc. form.All experiment to carry on in the artificial weather box and glass heat room.Experiment the result enunciation:The paddy rice teaches the period water in the stupid content of the nitric at the 0.051 mgs/ L( namely the national security drinking water 300%) the following is safe, have no influence to the rice seedling growth.
