潢川县杨围大队地处丘陵,有耕地2791亩,其中水田2291亩,水田中,表潜青泥田占1211亩,为水田面积的54％。一年一季水稻,亩产400斤左右。表潜青泥田是一种低产水稻土。其成土过程虽不受地下水影响,但耕层终年浸水泡田,在淹水条件下,土壤水份饱和,通气孔隙最微量5—8％。通透性能差,不利于好气性微生物活动,有机质分解缓慢,而持水空隙高达86％,影响水、气的协调和供应。如付老店生产队青泥田剖面一青泥层出现在剖
Huangchuan County Yangwei brigade is located in the hills, 2791 acres of arable land, of which 2291 acres of paddy fields, paddy fields, green table paddy fields accounted for 1211 acres, 54% of the paddy field area. One year rice, about 400 pounds per mu. Table diving green mud field is a low-yielding paddy soil. Although the process of soil formation is not affected by groundwater, the topsoil flooded soaked fields all the year round. Under flooding conditions, the soil moisture was saturated with the minimum 5-8% of aeration pores. Poor permeability, is not conducive to aerobic microbial activity, organic matter decomposition slow, and holding water gap up to 86%, affecting water and gas coordination and supply.
