惰性粉杀虫对稻谷品质的影响

INSECTICIDE EFFECT OF INERT DUST ON RICE QUALITY

采用药膜法和混粮法研究不同单因素对谷蠹和杂拟谷盗的防虫杀虫效果,以及食品级惰性粉添加后,对稻谷出糙率、整精米率、碎米率和爆腰率等加工品质的影响。试验表明,环境温度越高,惰性粉致使储粮害虫全部死亡的时间越短,杀虫效果越好,而剂量对惰性粉杀虫效果的影响较小,在低温条件下,害虫全部死亡的时间随剂量的增加而减少,但高温情况下,两种害虫的全部死亡时间并不随着剂量的增加而改变。此外,惰性粉的添加对稻谷的出糙率、整精米率、碎米率、爆腰率等加工品质没有太大影响。

In this paper,food-grade inert dust was used as the research material,and the effects of different single factors on the prevention and insecticide effects of dominica and tribolium castaneum were studied by using the medicinal film method and the mixed grain method,and after adding of food-grade inert dust,the effect of processing quality of paddy,such as the husked rice yield,head rice rate broken rice rate and crackle rate.Experiments showed that the higher the ambient temperature,the shorter time the inert dust causing death of all pests,and the better the insecticidal effect.The dose has less effect,and the time for all the insect pests death is low at low temperature.Decreases with dose,but at high temperatures,the total time of death for both pests does not change with increasing dose.In addition,the experimental data showed that the addition of inert dust has less effect on the processing quality of rice,such as the roughness,head rice rate,broken rice rate,and popping rate.
