为提高秋大棚番茄生产技术水平,促进北京市设施蔬菜产业的稳定发展和郊区菜农增收致富,共安排10个秋大棚番茄的高产技术试验点并总结高产栽培技术经验。结果表明,获得高产的关键是选用抗病、耐热品种,在6月20日播种育苗,苗龄25～30d,定植前施足底肥,每667m2施腐熟有机肥5m3,复合有机肥125kg、尿素25kg,定植时667m2密度在3200株以上,留4穗果,每株留果数12～14个并及时蘸花保果,防治病虫害。
In order to improve the technical level of tomato production in autumn greenhouses, promote the stable development of the facilities vegetable industry in Beijing and increase the incomes of vegetable farmers in suburbs, a total of 10 high yield technical test points for autumn tomato were arranged and the high-yielding cultivation experience was summarized. The results showed that the key to obtain high yield was selection of disease-resistant and heat-tolerant cultivars. Seedlings were planted on June 20, 25-30 days old. Planting fertilizer was applied before planting, 5m3 composted organic fertilizer per 667m2, 125kg composite organic fertilizer, 25kg, colonization 667m2 density in more than 3200, leaving 4 spike fruit per plant remaining fruit number 12 to 14 and timely dipped in flowers and fruit, pest control.
