三氯乙醛(酸)是很多化学工业的中间体,是生产某些农药、医药等有机合成物的原料。用这些工业上的含有三氯乙醛(酸)的废酸与磷矿粉制成的过磷酸钙,称为废酸磷肥(下同)。废酸磷肥中的三氯乙醛(酸)达到某种程度就要污染农田,危害农作物生长,轻则减产,重则绝收。近几年来,我省施用废酸磷肥的农田,初步统计受害面积已达30余万亩,损失巨大。外省也有同样事故。为探讨夏玉米对磷肥中三氯乙醛(酸)的耐性,以避免废酸磷肥污染农田,又合理
Chloral (acid) is a chemical intermediates for many chemical industry, is the production of certain pesticides, pharmaceuticals and other organic compounds raw materials. Using these industrial-grade trichloroacetaldehyde (acid) -containing spent acid and phosphate rock powder made of superphosphate, known as the waste acid phosphate fertilizer (the same below). Waste acid phosphate in the chloral (acid) to a certain extent, it will pollute the farmland, endanger the growth of crops, ranging from cut production, re-harvest. In recent years, the province’s use of waste acid phosphate fertilizer farm, the initial statistics of the victim area has reached 30 million mu, a huge loss. Other provinces also have the same accident. In order to discuss the tolerance of summer maize to trichloroacetaldehyde (acid) in phosphate fertilizer and to avoid the waste acid phosphate fertilizer to pollute the farmland, it is reasonable
