稻谷自然低温辅助通风保鲜技术研究——Ⅳ通风低温与保护剂结合防虫技术研究

STUDY ON THE TECHNIQUES OF KEEPING FRESHNESS OF RICE AT NORMAL COLD TEMPERATURE WITH AIDES OF VENTILATION——Ⅳ. STUDY ON THE TECHNIQUES OF PEST CONTROLLING BY COMBINATION OF VENTILATION AND PROTECTAUTS

根据我国通风低温与保护剂的发展现状,促进二者有效结合,探讨华南地区利用冬季通风降温,对提高和延长保护剂药效效果。经在防效、残留和残效的测定结果表明,采取通风降温并适当隔热,防虫磷、凯安保不仅药效提高,且有效期延长,尤以防虫磷显著,肯定了通风低温与保护剂结合的有效性。

According to the present conditions in application of ventilation for decreasing temperature of grain and in development of protectants in our country, the authors make a probe into the effec-tive combination of the two factors and utilization of winter wind for decreasing temperature of grain in the South China and increasing and proloning insectocode effectiveness of protectants. The results front the determination of controlling effectiveness, remainders and the effectiveness of remainders show that the effectiveness of malathion and K-obiol is not only obviously increased, but their useful life is also prolonged by ventilation and heat insulation. The good effectiveness of combination of ventilation for decreasing temperature with protectants is identified.
