作者从1981年开始研究了适用于塑料大棚番茄早热栽培技术措施:(1)改革育苗程序,即为火墙或恒温箱催芽→营养盘无土播种→营养袋培养土分苗于温室→移苗至阳畦→根部带培养土定植到大棚。因此,缓苗时间短,提早成熟5天。用无土快速育苗法,60天左右可育成大龄苗。(2)该区适合幼苗低温锻炼的气温指标为,白天22—25℃,上半夜14—10℃,下半 Since 1981, the author has studied the technical measures for early-heat cultivation of tomatoes in plastic greenhouses: (1) reforming the seedling raising program, that is, germination of fire walls or incubators → soilless sowing of nutrient plates → nutrition bags for cultivating soil seedlings in greenhouse → transplanting To Yang 畦 → roots with culture soil planting to the greenhouse. Therefore, Huanmiao time is short, mature five days earlier. With soilless rapid nursery law, about 60 days can grow older seedlings. (2) The temperature index suitable for the seedling’s cold exercise is 22-25 ℃ in the daytime, 14-10 ℃ in the middle of the night, the lower half
