确定一茬菇新鲜空气的需要量,可以通过计算采菇期间有机物损失的速率。在带有测定新鲜空气进气量的商业菇房中,可直接测定CO_2含量。一般空气中含有0.03％CO_2,如果要求的CO_2含量是0.06％,即比空气中高0.03％,由于培养料产生的CO_2浓度较高,需要用新鲜空气来稀释;如果要将CO_2含量提高到0.09％,即比空气中的高0.06％,所需新鲜空气量只要上述一半即可。大约以100英尺~3新鲜空气/吨培养料为好。 Tschierpe等在覆土后头25天测到的CO_2产生
Determine the amount of fresh air required for a stubble, by calculating the rate of organic losses during canning. CO 2 content can be determined directly in a commercial mushroom house with fresh air intake. Generally, the air contains 0.03% CO 2. If the required CO 2 content is 0.06%, which is 0.03% higher than that in the air, fresh air should be used to dilute the CO 2 because of higher CO 2 concentration in the culture material. If CO 2 content is to be increased to 0.09% , Which is 0.06% higher than in the air, and the amount of fresh air required is only half of the above. About 100 feet to 3 fresh air / t culture material is better. Tschierpe et al. Found CO 2 production in the first 25 days after soil cover
