本文从和用不同量粉煤灰配制床土进行水稻大棚盘育苗试验结果看出:处理4(粉煤灰2.5份+土2.5份+草炭5份)和处理3(粉煤灰2.5份+土5份+草炭2.5份)的稻苗健壮,根系发达,叶龄大,叶片挺拔,茎粗,百株干重多,充实度也较高,秧苗富有弹性,适宜机械插秧。说明在水稻育苗床土中加入适量的粉煤灰既增加了营养,又改善了床土的理化性质,对培育健壮的水稻秧苗起到了良好的作用。
In this paper, and with different amounts of fly ash preparation soil bed for the cultivation of rice in the greenhouse plate results showed that: Treatment 4 (2.5 parts of fly ash + 2.5 parts of earth and peat 5) and treatment 3 (2.5 parts of fly ash + soil 5 copies + 2.5 parts of peat) seedling robust, root system, leaf age, leaves tall and straight, stem thick, more than one hundred dry weight, substantial degree is also high, seedling flexible, suitable for mechanical planting. The results showed that adding proper amount of fly ash to paddy soil bed increased nutrition and physical and chemical properties of bed soil, which played a good role in cultivating robust rice seedlings.
