图2表明,尽管通风仓粮温一直低于不通风仓,特别在1、2月份,二者温差达10℃以上,但二者都是由开始到9月下旬将近两个月的储期内迅速降解;以后直到试验结束的6月,则稳定而缓慢地降解。图1和图2所示结果说明,通风低温对防虫磷和凯安保降解的影响有明显的差别。对防虫磷能够明显地延缓其降解速度。对凯安保则没有明显的延缓效果。无疑这是由于二者热稳定性不同的结果(Desmarchelier,1979)。因此,通风低温与不同类型保护剂相结合的效果也是有区别的。从本试验的结果来看,在应用防虫磷时,应尽可能与通风低温相结合;而在应用凯安保时,至少在华南不一定强调低温。这也就是说,在没有通风降温设施的条件下,应较多考虑使用凯安保。
Figure 2 shows that although the ventilation temperature has been lower than the non-ventilated warehouse fumes, especially in January and February, the temperature difference between the two reached more than 10 ℃, but both from the beginning of late September nearly two months of storage period Rapid degradation; after the trial until the end of June, then stable and slow degradation. The results shown in Fig. 1 and Fig. 2 show that there is a clear difference between the effects of ventilation and low temperature on the insecticidal phosphorus and Ka’anbao degradation. Insect-resistant phosphorus can significantly delay the degradation rate. There is no obvious delay effect on Kaian Bao. This is undoubtedly due to the difference in thermal stability between the two (Desmarchelier, 1979). Therefore, ventilation and low temperature with different types of protective agent is also a combination of the effect is also different. From the results of this experiment, the application of pest control phosphorus should be combined with ventilation and low temperature as much as possible; and in the application of Kempinsh, at least in southern China may not necessarily emphasize the low temperature. This means that in the absence of ventilation and cooling facilities under the conditions should be more consideration to the use of Kay security.
