摘 要:用稻谷加工的副产物稻壳,冬季初覆盖在日光温室地表,冬季末使其燃烧炭化,试验结果表明:覆盖稻壳可防寒保温,稻壳燃烧炭化时,温度高可加快土壤解冻,提早播种,提早上市,提高蔬菜价格,还可减少燃煤量,可增收9元/m2。稻壳富含钾,燃烧炭化后的灰翻入土壤中,增加土壤中速效钾的含量,速效钾提高5倍以上。Rice husk, a by-product of rice processing, was used to cover the land surface in sunlight greenhouse in early winter and then charred in late winter. The charred husk released high temperature which could melt the frozen earth, Therefore, the sowing was advanced, and so was marketing. The price of vegetable was increased and the cost of coal saved. As rice husk is rich in potassium, the rapidly available potassium in soil was increased after the charred husk was blended into the soil.
