| 摘 要： | 以番茄品种硬粉8号为试材,选用草炭和蛭石混合基质,采用二元二次正交旋转组合设计,研究智能温室条件下潮汐灌溉营养液供液维持时间和间隔时间对番茄穴盘苗质量的影响。结果表明:穴盘苗长至五叶一心时,幼苗全株干质量和壮苗指数均随着供液维持时间的延长呈先增加后下降的趋势,随间隔时间的延长呈逐渐下降的趋势;供液维持时间8~18min、间隔时间198~348min,番茄穴盘苗质量达到理想状态,是本试验条件下最佳水肥供给方案。

| Abstract: | Taking tomato variety‘Yingfen No.8’as test material，this paper used peat and vermiculite as mixed matrix to study in tidal irrigation and under intelligent greenhouse condition the effects of nutrient supplying maintaining time and interval time on quality of tomato seedlings raised on trays with central composite rotatable designs of 2 factors．The results showed when tomato grew 5 leaves and 1 heart，with the increase of nutrient supplying time，the seedling dry matter and strong seedling index showed first increasing then declining trend．While along with the interval time extension of nutrient supplying，the seedling dry matter and strong seedling index showed a declining tendency．The optimal nutrient supplying scheme is in 8-18 min of maintaining time and 198-348 min of interval time．Thus the seedling quality could achieve an ideal situation．We believe under the experiment condition，this solution is the best water and fertilizer supplying scheme． |
