凤凰县有潜育性稻田20,271亩,占稻田总面积7.8％。这类田泥脚深,长期冷浸渍水,造成土壤结构不良,通透性差,水温、泥温上升慢,变幅小,还原物质多,土壤有机质含量高,但有效养分缺乏,水肥气热失调,插秧后前期易形成僵苗,后期贪靑晚熟,因而生产力水平低,一般亩产300—400斤,严重地施了全县粮食生产的后腿。为了使这类稻田由低产变高产,1984年全县推广起垄栽培示范一百亩,平均增产14.23—16.8％。木里乡示范30亩,平均亩产856.5斤,比1983年亩增356.5斤,增长72.3％,效果显著,深受农民欢迎。
Fenghuang County has 20,271 mu of fertile rice fields, accounting for 7.8% of the total paddy field. Such deep muddy feet, long-term cold immersion water, resulting in poor soil structure, poor permeability, water temperature, temperature rise slow, small amplitude, reducing substances and more soil organic matter content, but the lack of effective nutrients, water and fertilizer gas thermal imbalance After the transplanting, it is easy to form a stiff seedling in the early stage of rice transplanting, and late late gluttony. Therefore, the level of productivity is low, generally 300-400 jin per mu is produced, which severely imposes a hind leg on grain production in the county. In order to make this type of paddy field from low to high output, in 1984 the county to promote ridge cultivation demonstration hundred acres, an average increase of 14.23-16.8%. Muli Township demonstration 30 acres, an average of 856.5 kg per mu, 356 kg more than 1983 acres, an increase of 72.3%, the effect is significant, welcomed by farmer.
