一、做好移栽前的准备工作1.烟田的选择一要选择排灌方便通风向阳的田地,特别要注重旱能灌、涝能排的条件。二要选择质地疏松、土层深厚、熟化程度高、通透性好、肥力中等的土地,呈微酸性为宜(pH值为5.5～6.5)。三要合理轮作。一般1～2年轮作谷类作物,不能与茄科或葫芦科作物(如番茄、辣椒、瓜类等)轮作。四要相对集中连片。集中连片种植便于加强管理和普及先进生产技术。 First, do a good job before transplanting 1. The choice of a tobacco field to choose a convenient ventilation sunny field, with particular emphasis on dry irrigation, waterlogging conditions. Second, to choose a loose texture, deep soil, high degree of maturity, good permeability, medium fertility land, was slightly acidic (pH 5.5 ~ 6.5). Three to make a reasonable rotation. Generally 1-2 years rotation cereal crops, not with Solanaceae or Cucurbitaceae crops (such as tomatoes, peppers, melons, etc.) rotation. Four should be relatively concentrated contiguous. Concentrated contiguous planting to facilitate the strengthening of management and popularization of advanced production technology.
