摘 要:在草莓基质穴盘避雨育苗模式下,研究了不同覆盖方式及滴灌带间距等因子对基质水分含量及草莓子苗的影响,结果表明:无纺布覆盖处理的穴盘与无覆盖物直接滴灌(CK)相比,水分扩散渗透距离远且均匀,离滴孔0.09 m以上基质含水量明显提高了24%~116%;滴灌带间距为0.100~0.175 m时,基质平均含水量在19.34%~20.24%之间,能有效地满足草莓子苗的正常生长需求,因此实际生产中的滴水管间距宜在0.125~0.175 m之间;滴水管间距为0.175 m处理除繁苗系数略低于传统地面裸根育苗外,其成苗株率、发病株率和炭疽病病情指数均优于对照和基质穴盘无纺布覆盖露地育苗。The strawberry seedlings were cultivated on the plate with substrate in shelter, and the influences of different covering modes and drip irrigation strap spacing on substrate moisture content and strawberry seedlings were studied. The results indicated that: in comparison with the treatment of direct drip irrigation without covering (CK), the non -woven fabric covering treatment had better effect, the water in the substrate diffused farther and more uniform, and the moisture content in the substrate more than 0.09 m far from the drip hole was significantly increased by 24% - 116%. When the drip irrigation strap spacing was 0. 100 ~0. 175 m, the aver- age moisture content in the substrate was 19.34% - 20. 24%, which could effectively satisfy the normal growth of strawberry seed- lings. So the proper drip irrigation strap spacing was 0. 125 ~0. 175 m in the actual production. The treatment of drip irrigation with the water - pipe spacing of 0. 175 m was better than CK and non - woven fabric covering treatment in seedling ratio, sick seedling ratio and anthrax disease index, while its seedling propagation coefficient was slightly lower than that of the traditional naked - root seedling - raising treatment.
