番茄是北方人最喜欢的蔬菜之一,怎样能在寒冷的地区使番茄早上市,提高早期产量,这个问题一直很受重视。除采取化学药剂催熟外,定植方法也直接影响番茄的成熟期和产量。近几年的栽植实践证明,早春露地定植番茄采用“L”形根向阳栽培方法可使番茄提早成熟2～3天,使前期产量增加20～30％。
Tomatoes are one of the northerners’ favorite vegetables. How to get tomatoes to the market early in the cold and increase early yields has always been the subject of great attention. In addition to chemical ripening, planting methods also have a direct impact on tomato maturity and yield. In recent years, planting practice has proved that early spring open field planting tomatoes with “L” -shaped sun-cultivation methods can make tomatoes mature 2 to 3 days earlier, the pre-production increased by 20 to 30%.
