以节水抗旱稻品种旱优8号为材料,基质配方是将60%蚯蚓粪、30%蛭石、10%菜园土混合均匀初制成复合基质设计添加不同质量(20、30、40、50、60克/塑盘)的七水硫酸亚铁组成不同的复合基质处理,对照为市售基质,研究其对旱育秧苗素质的影响。结果表明,添加不同亚铁含量的复合基质培育 Taking drought-tolerant drought-tolerant rice variety “Yanyou 8” as material, the matrix formulation was made by mixing 60% earthworm excrement, 30% vermiculite and 10% vegetable garden soil into a composite matrix and adding different quality (20, 30, 40, 50 , 60 g / plastic plate) of different composition of ferrous sulfate heptahydrate matrix control, the control for the commercially available substrate, to study the quality of the seedlings of dry nursery. The results show that the addition of different ferrous content of composite substrate culture
