摘  要：
对三氯乙酸研究结果表明,TCA是生长紊乱剂,受害轻者使作物致畸,重者使作物致死;可随土壤水分上下移动,但不沉积于下层,在40cm土层以下由于土壤微生物的消解作用而消失。TCA在植株体内的残留以3叶期较多,但在籽粒中的残留甚微。TCA在磷肥中的剂量为200mg/kg时,对作物的危害不明显,是安全剂量;在400mg/kg时,出苗率达90%以上,减产4.4%,差异不显著,为临界剂量;800mg/kg时平均减产19.1%,是禁止使用剂量。

摘  要：
A study on trichloroactic acid (TCA) was conducted. The reslut showed that TCA was a growth disorder substance to harm crops. The crop gorwth showed that the light harmed plants by TCA would be distorted and the heavily harmed plants would be died. It could move up and down with the water but was not sediment in deep soil layer, and dispelled underground 40 cm because of microbial degradation. There were higher TCA residua in plant at the period of plant with three leaves but very little in seeds. So TCA harm to crop can be controlled. Its harmness will be insignificant when TCA content in phosphate fertilizer is less than 200 mg/kg which is safe. And seedling emergence is over 90% when TCA content in phosphate is less than 400 mg/kg which decreases yield by 4.4% and is critical. The yield will be decreased by 19.1% when TCA content in phosphate is 800 mg/kg which is forbidden.
