作者将马拉硫磷和杀螟松配成乳剂,施药于硬质红春小麦中,剂量为8ppm,药剂处理后的小麦分别置于-35℃、-20℃、-5℃、5℃、10℃、20℃、27℃温度下贮藏,贮藏72周中定期测定各种温度下贮藏小麦中两种药剂的残留量,发现贮藏温度越高,小麦中残留量越低,贮藏期越长,小麦中药剂残留也越低。两种药剂相比较,杀螟松比马拉硫磷在小麦中滞留性要长些,尤其是在低温下。以8ppm和12ppm剂量的马拉硫磷和杀螟松处理含水量为12.5%的小麦,分别贮藏在-5℃、10℃、20℃温度下12个月后将小麦加工成粉,发现,随着贮藏温度的增高和贮藏期的延长,研磨后小麦各组份中药剂残留量而降低。小麦各组份药剂残留相比较,麦麸和粗粉中的药剂残留比面粉中要高。
The author drew malathion and fenitrothion as the emulsion and applied it in hard red spring wheat at the dosage of 8ppm. The treated wheat was placed at -35 ℃, -20 ℃, -5 ℃, 5 ℃, 10 ℃, 20 ℃, 27 ℃ storage temperature, storage for 72 weeks in the regular determination of the temperature of wheat stored in two kinds of pharmaceutical residues, found that the higher the storage temperature, the lower the residual wheat, the longer the storage period, The lower the residue of wheat in medicine. Compared with the two agents, fenitrothion longer than malathion retention in wheat longer, especially at low temperatures. Wheat with water content of 12.5% was treated with malathion and fenitrothion at 8 and 12 ppm respectively and stored at -5 ℃, 10 ℃ and 20 ℃ for 12 months, With the increase of the storage temperature and the prolongation of the storage period, the residual amount of the pesticide in each component of the wheat decreased after grinding. Residues of wheat bran and meal are higher than those of wheat flour in comparison with those of wheat flour.
