潜育性稻田在我县占有一定的比例,产量很低。这类田受冷水浸灌,水冷泥温低,且常年泡冬和长期淹水平栽,土壤次生潜育化严重。泥烂、泥脚深,通透性差,还原作用强,有毒物质多,常造成水稻根系发育不良,前期易坐蔸死苗,中后期易感染病虫害;茎秆细弱,穗子细小,单产量不高,是长期来障碍水稻增产的因素之一。1984年,我们根据外地经验,在总结当地农民经验的基础上,将水稻半旱式栽培技术应用于冷浸烂泥田的改良,取得了十分明显的增产效果。 Diverting paddy fields occupy a certain proportion in our county, yield is very low. This kind of field is affected by cold water infiltration irrigation, low temperature water-cooled mud, perennial soaked winter and long-term submerged flat soil, secondary soil gleization seriously. Muddy, deep mud feet, poor permeability, strong reduction effect, many toxic substances, often resulting in poor growth of rice roots, pre-easy to sit Miao dead seedlings, susceptible to pests and diseases in the late; thin stalk, small ears, single yield is not high , Is one of the factors hindering the increase of rice yield in the long term. In 1984, based on the field experience, based on the experience of local farmers, we applied the semi-arid rice cultivation technology to the improvement of the cold-soiled muddy fields and achieved a remarkable yield increase effect.
