[目的]以水稻品种“龙稻11号”为供试品种,采用生物炭配合有机物料玉米秸秆和稻壳,同时添加有机肥、草炭、沸石、细河沙、耕层土等按一定的体积比混合,进行新基质的水稻育秧试验,研究生物炭配合有机物料新基质的理化性质及其对秧苗生长状况的影响。[方法]采用大棚育苗,随机区组试验。[结果]生物炭配合有机物料玉米秸秆和稻壳的基质能够提高基质的最大持水量,降低基质的容重,改善基质的p H缓冲性,对基质的碱解氮和速效钾含量影响较大,并且能够提高秧苗的发根数和充实度。[结论]生物炭配合有机物料玉米秸秆和稻壳的基质(处理HC)为最优基质。
[Objective] With the rice variety “Longdao 11” as tested varieties, biochar was used to mix corn stover and rice husk with organic materials, while adding organic fertilizer, peat, zeolite, fine river sand, Of the volume ratio of hybrid rice seedlings for new substrate experiments to study the physical and chemical properties of the new substrate of biochar with organic materials and their effects on the growth of seedlings. [Method] The greenhouse nursery, randomized block test. [Result] Biochar combined with organic maize straw and rice hull matrix could increase the maximum water holding capacity of matrix, reduce the bulk density of matrix, improve the p H cushioning of matrix, and had a great effect on the contents of available nitrogen and available potassium. And the number of hair roots and the degree of fullness of the seedlings can be increased. [Conclusion] The optimal substrate was biochar combined with maize straw and rice hull matrix (treated with HC).
