粮堆一般有温差,粮食对PH_3的吸附和受温差支配的粮堆内气流运动是关系到AI P熏蒸效果的重要因素.本文通过对5米高小麦粮堆不同部位施药熏蒸试验,用测得粮堆各部位PH_3浓度分布速度和CT值评价不同施药部位的优劣.
Grain piles generally have temperature differences, grain PH3 adsorption and air temperature control within the grain flow is related to AI P fumigation effect of an important factor.Through the 5 m high wheat grain piles in different parts of the application fumigation test, measured The velocity and CT value of PH_3 concentration distribution in all parts of grain piles were used to evaluate the advantages and disadvantages of different application sites.
