1971—1972年,我们进行了用春番茄侧枝扦插育苗栽培夏番茄的试验。两年试验表明,在易发病的高温多雨季节,扦插的番茄病毒病较轻,产量比一般夏番茄高。1972年5月29日在0.77亩地上扦插的10个品种平均亩产5,432.7斤,其中5个品种亩产7,000斤以上,有1个品种亩产8,464.5斤。扦插栽培夏番茄要掌握以下四个关键措施: 一、掌握扦插适期北京地区7月份进入高温多雨季节,番茄最易发生病害,特别是病毒病往往造成严重为
From 1971 to 1972, we conducted the experiment of cultivating summer tomato with lateral shoot cutting of spring tomato. Two years of tests showed that in susceptible hot and rainy season, cutting tomato virus disease lighter, higher than the average summer tomato yield. On May 29, 1972, the average yield per mu of 10 cultivars on the ground of 0.77 mu was 5,432.7 kg, of which 5 cultivars were over 7,000 kg mu and 8,464.5 kg were mu per one cultivars. Cuttage cultivation of summer tomato to master the following four key measures: First, grasp the cutting period Beijing in July into the hot and rainy season, tomato most prone to disease, especially the virus disease is often caused by serious
