摘要
本文主要对黑龙江省哈尔滨市一定点大棚内土壤剖面通气孔隙的变化进行了研究.结果表明:土壤容重从表层向下依次增加,除0～10 cm层次外,土壤剖面其它各层次通气状况不好,并随着栽培时间的加长,日趋板结,严重影响作物的生长发育.
This article mainly studied the variation of aeration porosity in soil under shed protection in Harbin, Heilongjiang Province. The results showed that the soil aeration porosity was not very well. The bottom layer was quite low which was between 5. 62% and 8. 42%. But the upper kyer was quite good which was more than 15%.
