摘　　要：以宁两优1号为供试品种,比较分析了打印秸秆基质盘(T1)、秸秆基质盘(T2)、营养土(CK)所育秧苗的素质、移栽质量和水稻产量的差异。结果表明,播种后7 d,T1处理出苗数达2.50株/cm2,比T2处理和CK分别高出5.49%和2.88%,所育秧苗的株距离散程度三者中最小,播种均匀度较T2处理和CK分别提高25.00%和50.00%;茎基宽、发根力和根系盘结力明显优于T2处理和CK,分别高0.04 mm、0.28 cm、0.12 kg和0.33 mm、0.35 cm、1.89 kg;移栽后漏插率和飘秧率与T2处理差异不显著,但显著低于CK37.92%和58.98%,结实率分别比T2处理和CK提高1.95%和2.52%,千粒重分别增加1.56%和2.38%,产量分别提高6.27%和7.18%。结果可为水稻集中规模化育秧及推进机插秧水平进程提供理论支撑。The differences of seedling quality, transplanting quality and yield between printing seeding straw matrix block seeding(T1), straw matrix blocks seeding(T2), and nutrient soil seeding(CK) were compared and analyzed with Ningliangyou 1 as the test variety. The results showed that 7 days after sowing, the emergence number of T1 treatment amount to 2.5 plants/cm2, which was 5.49%and 2.88% higher than T2 treatment and CK, respectively. The spacing of seedlings cultivated on T1 treatment had the minimal dispersion degree, and sowing uniformity was increased by 25.00% and 50.00% respectively compared with T2 treatment and CK. The width of stem base, rooting ability of rice seedlings and the twisting ability of seeding root system were significantly increased 0.07mm, 0.28 cm, 0.12 kg and 0.33 mm, 0.35 cm, 1.89 kg to T1 treatment and CK. After transplanting, the missing transplanting rate and the floating seedling rate was not significantly different from T2 treatment, but 37.92% and 58.98% significantly lower than CK, the seed-setting rate was increased by 1.95% and 2.52%, the thousand-grain weight was increased by 1.56% and 2.38%,and the yield was increased by 6.27% and 7.18%, respectively. The results of this study could provide a theoretical support for the centralized and large-scale rice seedling raising and promote the process of mechanical transplanting.
