paraquat is one kind of weedicide that comprehensive used all over the world ,for its little pollute to the environ accept a generally welcome .but the poisoning of paraquat have become a more and more severe problem,especially in developing county.the paraquat have a hypso-toxicity to human ,its mortality is 85%~95%.it show a multisystem injury to human body but the most serious injury of the paraqat to the viscera is lung .the mechanism of damnification is the great deal of super-oxygen ion procreant by paraquat in lung .at present the best technique to the diagonose of the paraquat poisoning to lung injury is ct.

百草枯是目前全世界范围内应用最广泛的除草剂，以其对环境的低污染性而受到广泛欢迎，但是百草枯中毒也随之成为一个越来越严重的题目，尤其是在发展中国家。百草枯对人体呈高毒性，死亡率约为85%~95%。百草枯中毒表现为多系统损伤，但是对人体脏器最主要的损伤是肺损伤，损伤机制主要为百草枯在肺组织内产生的大量超氧离子。目前对百草枯中毒致肺损伤的诊断最佳的方式是CT。

The method is simple, has safe operation, creates an approach utilizing a plant gene to safely select the marker gene for the tomato genetic transformation, can replace the disadvantages caused by the widely used heterogenous genes such as antibiotic genes, weedicide resistant genes, xyl A, pmi, GUS and so on, taken as marker genes, obtains a transgenic tomato with food safety, biological safety and ecological safety, relieves the public from anxiety of marker gene safety, and inevitably facilitates the commercialized application of the transgenic tomato.

该方法简单，操作安全，开创了利用植物基因作为番茄转化安全筛选标记基因的途径，能够代替目前广泛使用的抗生素基因、抗除草剂基因以及xylA、pmi、GUS等异源基因作为标记基因存在的弊端，获得具有食品安全性、生物安全性和生态安全性的转基因番茄，解除公众对标记基因安全性的顾虑，必将促进转基因番茄的商业化应用。

Methods The pesticides were extracted with acetone and dichloromethane, warmed with water at 40℃,and circumrotated and evaporated until it was nearly dry, then it was purified by Envi Carb column and Sep Pak NH2 column. Afterwards, gas chromatography mass spectrometry and selected ion monitoring were used to determine 42 pesticide residues, such as organo-phosphorus, pyrethroid, organochlorine, carbamate and weedicide.

该法采用丙酮、二氯甲烷提取，40℃水浴旋转蒸发近干，以Envi-Carb柱和Sep-Pak-NH2柱净化，以气相色谱－质谱选择离子监测方式分析检测有机磷、有机氯、拟除虫菊酯、氨基甲酸酯和除草剂等42种农药残留。

Potassium carbonate, potash fertilizer, protein feed, feed aureomycin, mycelium, bran, lees, food seed, weedicide, fibrin, calcium hydrophosphate, etc.

碳酸钾、生物钾肥、蛋白饲料、饲料用金霉素、菌丝体、麸皮、酒糟、粮食、种子、除草剂、纤维素、饲料磷酸氢钙等。

Seed cotton yield of 7.9 t/ha and 7.2 t/ha have been achieved under experimental conditions and under on-farm trials in farmers' fields (Bhatti, 1. M, et al, 1981). During 1991 at a private farm of Mr. Sadiq Akbar Bokhari in Multan area of Punjab, average yields of 3.5 t/ha equivalent to 1.2 t lint/ha from an area of 80 ha and 4.5 t/ha equivalent to 1.5 t lint/ha from an area of 20 ha were obtained. Recommended agronomic practices including the application of weedicide, pesticides, fertilizers (125-50-50 N-P2O5-K2O kg/ha) besides planting of cotton on ridges were followed. Crop was planted between 5-30 June and harvested between November and following February. Wheat was planted on 4 ha in standing cotton in the end of November and produced 2.8t/ha yield.

在试验条件下和农民田地的大田试验中已获得籽棉7.9吨/公顷和7.2吨/公顷的高产（Bhatti，I.M，等1981）。1991年在旁遮普省木尔坦地区，Sadiq Akbar Bokhari 先生私人农场的80公顷土地上，籽棉平均产量3.5吨/公顷，折合皮棉1.2吨/公顷，另外20公顷土地上籽棉4.5吨/公顷，折合皮棉1.5吨/公顷，推荐的农艺措施包括使用除草剂、农药、肥料（125-50-50 N- P2O5- K2O公斤/公顷）以及起垄种植棉花。6月5~30日种棉，11月至次年2月采收，11月底在4公顷站立棉株间套种小麦，单产小麦2.8吨/公顷。
