株间加温对设施番茄生长发育的影响

Effect of heating between strains on protected tomato growth and development

以"朝研—299"设施番茄品种为试材,在定植前对其设置两种加温方式(株间加温、常规前置式加温),研究两种加温方式在设施番茄栽培中对番茄生长发育的影响。对不同加温方式下的设施番茄株高、茎粗、叶绿素、单果鲜果重、亩产量和增产率的数据采集进行对比分析。选用的两种加温方式对设施番茄株高、茎粗、叶绿素含量在冬季生产中能起到稳定控温的作用。不同加温方式对设施番茄生长特性影响不同,其中株间加温对设施番茄的补温效果明显,尤其是株间加温60cm处理下的设施番茄在果实品质和产量上作用效果显著提高。这种加温方式为进一步试验示范和大面积推广应用提供数据依据。

Taking protected tomato ＂Zhaoyan-299＂ as experimental materials, two heating ways （heating between strains and con- ventional superposed heating）were adopted in the experiment before engraftment, and effects of two ways on tomato growth and de- velopment were studied. Plant height, stem diameter, chlorophyll content, weight of per fruit, yield of per unit and yield increasing rate after heating were collected and compared. The results show that two heating ways can control the temperature stable, and differ- ent heating ways have different influence on growth characteristics of protected tomato. Heating between strains appears obvious war- ming performance, especially with the pipe height 60era, yield and quality of tomato are significantly improved. This paper provides data base for the demonstration, promotion, and application of heating between strains.
