多效唑在日光温室番茄高产栽培中的应用研究

OnAppliection of MET to Tomato High-yield Cultivation in Sunlight Greenhouse

多效唑能有效地控制日光温室番茄的营养生长，促进生殖发育和提高产量。提高座果率11．41％，果实脱落率降低3．38％，单果重增加14．8g，平均增产20．21％。喷施时期和用药浓度的最佳组合是：初果期＋200mg·L-1。

The experimental result showed that MET (multieffect trlazole)can effectively restrain the nutrient growth and promote reproductive growth and increase the yield of tomato in sunlight greenhouse. The percentage of ferile fruit is raised by 11. 4%,the percentage of fruit abscission is reduced by 3. 38%,single fruit weight is increased by 14. 8g and mean yield is increased by 20- 21 %. The best combination of spouting stage and applying consistency is:primary fruit stage +200mg· L^-1.
