上海郊区每年栽培春番茄3万亩左右。由于番茄苗期处于低温阶段,影响花芽分化,造成早期果子畸形果(“老虎脚瓜”),随着早熟栽培的不断发展,春番茄畸形果更为严重。1986年、1987年,据对市郊6个乡的调查表明,第一花序畸形果在25％左右,高的达40％,最高的达60％以上。每年因畸形果造成的产量损失约为8000到10000吨,经济损失200万到250万元,影响了生产者和消费者的利益。为了减少畸形果的发生,提高番茄质量,增加
Shanghai suburbs annual cultivation of about 30,000 acres of spring tomatoes. As the tomato seedling stage is at a low temperature, affecting flower bud differentiation, resulting in early fruit malformation fruit (“Tiger foot melon”), with the continuous development of precocious cultivation, spring tomato deformity is more serious. In 1986 and 1987, according to a survey of 6 townships in the suburbs, the first inflorescence malformation fruit was about 25%, the highest reached 40% and the highest reached 60%. Annual yield loss due to deformity is about 8,000 to 10,000 tons, economic losses of 2 million to 2.5 million yuan, affecting the interests of producers and consumers. In order to reduce the occurrence of deformed fruit, improve tomato quality, increase
