冷、烂、锈田是低产田的一种类型,主要分布在山区、半山区、丘陵区,面积较大,常年亩产250~30公斤,少则100~150公斤。其低产原因是:地下水位高,土壤通气状况不良,土温低,硫化氢等还原性毒物多,速效养分含量少,供肥性差,耕性不良,水稻移栽后常出现黑根、坐蔸、僵苗、甚至死亡。改良的方法如下: Cold and rotten, rusty field is a type of low-yield field, mainly distributed in mountainous, semi-mountainous and hilly areas, with a large area. Annual perennial mu produce 250 ~ 30 kilograms, ranging from 100 ~ 150 kilograms. The causes of low yield are: high groundwater level, poor soil aeration, low soil temperature, hydrogen sulfide and other reducing toxic substances, less available nutrient content for poor fertility, poor tillage, black transplanting rice often appear, , Stiff seedlings, and even death. Improved method is as follows:
