摘要：

以晶两优534和甬优1540为材料,于2021年在贵州省兴义市开展菌渣不同施用比例（体积比为20%、40%、60%和80%）对水稻秧苗素质影响的试验。结果表明,与耕作土育秧（对照）相比,育秧基质中施用一定比例菌渣对水稻秧苗根数、茎基宽等农艺性状和干物质积累等影响不显著;随着菌渣施用比例的增加,秧苗的整齐度增加,25 d秧龄时,菌渣施用比例为60%和80%的处理,2个品种秧苗的整齐度分别比对照高9.8%~13.1%和12.0%~19.4%,差异显著,40 d秧龄时各处理间整齐度差异不显著;相比对照,施用菌渣的处理秧苗叶片叶绿素含量升高,尤其是40 d秧龄施用60%和80%菌渣的处理,2个品种叶片叶绿素含量分别比对照高13.4%~35.9%和7.6%~17.3%。因此,在耕作土中混合60%~80%体积的菌渣有利于提高秧苗的整齐度和叶片叶绿素含量,提高秧苗素质。

Abstract:

The experiment was carried out in April 2021 to clarify the effects of different application ratios（20%, 40%, 60% and 80% by volume） of mushroom cultivation residue on the quality of rice seedlings of hybrid rice combinations Jingliangyou 534 and Yongyou 1540. The results showed that, compared with control（cultivated soil for raising seedlings）, the application of a certain proportion of mushroom cultivation residue in the seedling substrate had no significant effect on the agronomic traits such as root number, stem base width and dry matter accumulation of rice seedlings. With the increase in the proportion of mushroom cultivation residues, the uniformity of the seedlings increases. At the 25-day seedling age of the two tested varieties, the uniformity in the treatments with 60% and 80% mushroom cultivation residues were 9.8%~13.1% and 12.0%~19.4% higher than the control, respectively, showing significant differences. There is no significant difference in uniformity among different treatments at 40-day seedling age. Compared with the control, the chlorophyll contents in the leaves in the treatment with mushroom residue increased, especially in the treatments with 60% and 80% of the mushroom residue at 40-day seedling age, the chlorophyll contents of the leaves of the two combinations were 13.4%~35.9% and 7.6%~17.3% higher than the control, respectively. Therefore, 60%~80% mushroom residue addition to the cultivated soil was beneficial to improve the uniformity of the seedlings and the chlorophyll contents of the leaves, thereby improving the quality of the rice seedlings.
