煤炭燃烧后产生的煤炭有很大的利用价值,经过我们多年试验,可利用它改士、肥地、育苗,尤其是对早春蔬菜、玉米、棉花等作物的育苗培植有明显效果。 1.提高地温。由于煤灰的吸热保温性能好,播种后覆上一层煤灰,犹如给播下的种子盖上了地膜,使白天吸热多,晚上散热慢,从而提高了地温,改善了田间小气候。具体措施是:首先将苗床整理好,施入基肥,将种子撒播入土, Coal produced after combustion of coal has great value, after many years of testing, we can use it to change Shi, fat, nursery, especially for early spring vegetables, corn, cotton and other crops nursery and planting have a significant effect. 1. Improve the ground temperature. As the coal ash endothermic thermal insulation performance, covered with a layer of soot after sowing, like sowing the seeds covered with plastic film, heat absorption during the day and night, cooling heat slowly, thereby enhancing the ground temperature and improve the field microclimate. Specific measures are: first seedbed finishing, applied to the base fertilizer, sowing the seeds into the soil,
