设施补光对苏州地区“秋延后”番茄生长的影响

Effect of facility light supplementary on“autumn delay”tomato growth in Suzhou area

以‘金陵美玉’番茄品种为材料,研究不同补光处理对番茄生长发育的影响。结果表明:C1和C3处理比CK处理提前20 d上市,采摘总产量中C1和C3处理分别是CK的4.1倍和5.0倍。除单果重外,C1和C3处理的各产量构成因素显著高于C2和CK。定植后35 d和50 d,C3的株高和茎粗最大、CK最小。定植后70 d和80 d,C1的株高和茎粗最大、CK最小。C1处理和C3处理的单株产量与C2的单株产量分别是CK的5.5倍和3.07倍。补光可提升叶绿素含量,减少病虫害,降低冬季低温弱光高湿等不利环境的影响。点光源冠层补光+线光源丛间补光(C1)更有利于苏州地区“秋延后”设施番茄的栽培。研究结果对该区域的黄瓜、辣椒、草莓等设施果菜或浆果的冬春季栽培具有示范和借鉴作用。

The‘Jinling Meiyu’tomato variety was selected as the material to study the effects of different light supplement treatments on the growth of tomoto.The results showed that the C1 and C3 treatments were listed 20 days earlier than the CK treatment,and the C1 and C3 treatments were 4.1 and 5.0 times that of the CK in the total yield of the five pickings.Except single fruit weight,the yield components of C1 and C3 treatments were significantly higher than those of C2 and CK.At 35 days and 50 days after planting,the plant height and stem diameter of C3 were the largest,and the CK were the smallest.At 70 days and 80 days after planting,the plant height and stem diameter of C1 were the largest,and the CK were the smallest.The yield per plant of C1 and C3 and the yield per plant of C2 were 5.5 times and 3.07 times,respectively,of CK.Illumination supplement could reduce the stress of pests and diseases,low temperature,weak light and high humidity.Canopy headlights+Inter-cluster LED supplemental light(C1)was more conducive to the facility cultivation of“autumn post-delay”tomatoes in Suzhou Area.The results of this study played an exemplary role and provided experience for the winter and spring facility cultivation of cucumbers,peppers,strawberries and other fruits or berries in this region.
