本文根据我国储粮通风和防虫保护剂的发展现状,为促进二者在应用中有效地结合,在现场探讨了我国气候温暖的华南地区,利用冬季自然低温,以通风的办法降低粮温,提高和延长保护剂药效的实际效果。经对防效、残留和残效的测定表明,在华南对施用了保护剂的储粮,采取通风降温措施,并在气温上升季节适当隔热,防虫磷(马拉硫磷)和凯安保(含增效醚的溴氰菊酯乳油)不仅药效提高,而且有效期延长,尤以防虫磷显著。肯定了在华南地区通风低温与施用保护剂相结合的可行性与有效性。
In order to promote the effective combination of the two in application, the paper discussed the warm southern China in our country according to the development status of grain ventilation and pest control agent in our country. By using natural low temperature in winter and reducing the grain temperature by ventilation And extend the actual effect of protective agent efficacy. The results of control, residual and residual effects showed that ventilation and cooling measures were applied to stored grain with protective agent in the South China and that there should be proper insulation during the warming season, pest control (malathion) and kaianbao Synergistic ether deltamethrin EC) not only improve efficacy, but also to extend the validity, especially pest control significantly. Affirmed the feasibility and effectiveness of the combination of low temperature ventilation and application of protective agent in southern China.
