我县有山垄冷浸田2.5万余亩,占水田总面积的10％左右。主要分布在山区和丘陵谷地的深山坞、山脚、溪渠边和低洼地段。山垄冷浸田由于水多、土壤通气状况不良,土温低,还原性毒物多,速效养分含量少,供肥性能差,耕性不良,产量低而不稳,一般亩产粮食在千斤以下,是我县主要低产田之一。但这种田一经改良,就能大幅度增产,增产潜力很大。我们从1979年开始实行综合治理,效果显著。全年粮食亩产比改良前平均增加419.6斤,增产率56.5％。
My county has a mountain ridge cold dipping more than 2.5 acres, accounting for about 10% of the total paddy field. Mainly located in the mountains and hilly valleys deep dock, the foot of the foot, canal edge and low-lying lots. Cold ridged ridge fields due to water, poor soil aeration, low soil temperature, reductive toxicants, less available nutrient content, poor performance for the poor, poor tillage, low yield and instability, the general per-mu produce less than a thousand pounds of grain , Is one of the major low-yield fields in our county. However, once this farmland has been improved, it will be able to increase its output substantially and increase its potential for production. We have implemented comprehensive management since 1979, with remarkable results. The annual grain output per mu increased 419.6 kilograms on average before the improvement, with an increase rate of 56.5%.
