With common pakchoi as the material, they were soaked in mixed solution with 1000 times of methyl parathion, dimethoate, dichlorvos, pyralid treat phosphorus, poison-to-death barnyard grass and fenvalerate for 1 min, and then they were saved in CW(25℃, humidity 55%RH), LC(4 ℃, humidity 60%RH) and DW (-24 ℃, humidity 70%RH) after air dried. After saved for 0, 24, 48 and 72 h, the samples from which were taken to determine the residual quantity of pesticides in pakchoi of different treatments.

方法］以普通小白菜为材料，将其在1000倍甲基对硫磷、乐果、敌敌畏、治螟磷、毒死稗和氰戊菊酯的混合稀释液中浸泡1 min，取出晾干后分别在CW（25℃，湿度55%RH）、LC（4℃，湿度60%RH）和DW(-24℃、70%RH)条件下保存，0、24、48、72 h后分别取样，测定各处理小白菜中农药的残留量。

The residues of methyl parathion had not been detected in seven days when it was used.

实验结果表明，甲基对硫磷在小白菜上半衰期为2.91天；喷药后第七天，在小白菜中未检出甲基对硫磷的残留。

Therefore, both the bioavailability and toxicity of selenate were greater than those of selenite under these experimental conditions.

小白菜根长、叶面积等生长指标均随Se和Se含量的增大而显著下降（p.01）；抑制小白菜根系生长的Se含量为60 mg·kg-1，明显高于Se含量（20.0 mg·kg-1）。

The effects of different ratio organo-inorgano-mixed nitrogen fertilizers application on nitrate contents of Chinese cabbage,swamp cabbage and tested soil were studied with plot experiment.

通过田间试验，研究了不同比例有机无机氮肥配施对小白菜和空心菜及供试土壤硝酸盐含量的影响。结果表明：有机无机氮肥比例为1∶1时，小白菜和空心菜以及土壤硝酸盐含量均为最低。

In this study, the effects on the growth of cabbage, Chinese cabbage and rape planted on fly ash plus vinasse substrate and fly ash plus sewage sludge substrate were studied and the remediation of cabbage, Chinese cabbage and rape on heavy metal Cd, Cu and Zn was discussed by calculating absorption coefficient, transmission coefficient and absorption modulus.

该文研究了粉煤灰加酒糟和粉煤灰加污泥两种基质对甘蓝、小白菜和油菜生长的影响，并通过计算吸收系数、转运系数和吸收模量讨论了甘蓝、小白菜和油菜对基质中重金属Cd、Cu、Zn的修复情况。

In order to study the pyrethroids pesticides stress on the physiological and biochemical process of vegetables, effects of different concentrions of fenvalerate stress (20% emulsifiable concentrate, recommended dose: 1500 times dilution; double dose: 750 times dilution) on the activities of antioxidant enzymes, and contents of malondiadehyde in pakchoi were investigated under the open-field condition.

为探讨菊酯类农药胁迫对蔬菜生理生化过程的影响，以小白菜为研究对象，采用大田试验研究了不同浓度氰戊菊酯（20%乳油，推荐用量：稀释1500倍；加倍用量：稀释750倍）对小白菜抗氧化酶活性及丙二醛含量的影响。

Meanwhile, the possibility to reduce Cd uptake and accumulation in pakchoi plants by application of Silicon or Selenium will be also studied.

Cd在不同品种小白菜中亚细胞分布的研究以差速离心法研究Cd在不同品种小白菜亚细胞的分布情况。

Effects of quinhydrone, as urease inhibitor, on growth, root activities, nitrogen metabolism, photosynthetic character, yield as well as quality were studied under pot experiment with water spanich and plot experiment with B.chinensis Var.comrtzunis. The results were shown as follow: 1. Applying low and medium amount quinhydrone promoted the growth of water spanich and B.chinensis Va,communis, whereas high amount treatment had little effect on water spanich growth, and inhibited the growth of B.chinensis Var communis.

以醌氢醌为脲酶抑制剂，蕹菜和小白菜为试材，研究了不同用量的醌氢醌对这两种蔬菜生长、根系活性、氮代谢、光合特性以及产量、品质的影响，结果表明：1 低、中量醌氢醌能促进蕹菜、小白菜的生长，高量醌氢醌对蕹菜的促进作用不大，对小白菜生长有抑制作用。
