中国农科院蔬菜所等单位针对北京市蕃茄连年低产、质劣的问题,连续三年进行了大棚蕃茄高产栽培研究,先后共试验13.9亩,平均亩产21255.1斤,亩产值1791.6元,高于一般大棚220.5％和131.2％,高于露地春蕃茄 426.5％和454.7％。高产棚1977年达25121.9斤,1978年达31642.7斤,连续两年创全国大棚蕃茄最高单产水平,1979年又持续达到30808斤,产值达3696.9元,超过日本温室最高亩产2万斤的水平,达到荷兰温室全年亩产2.6—3.3万斤的水平。果实品质极佳,采收期较一般大棚延长2个月,较露地栽培提前延后各1个月。总收获期延长两倍。通过栽培实践,提出了实现高产环境因子(温度、光照、水分等)控制指标和栽培
Chinese Academy of Agricultural Sciences and other units for the tomato tomatoes in Beijing in recent years, low-yield, quality problems, for three consecutive years of greenhouse cultivation of tomatoes, has a total of 13.9 acres of testing, the average yield 21,255.1 kg, 1791.6 yuan per mu, higher than 220.5% and 131.2% of the general greenhouses, 426.5% and 454.7% more than the open-air spring tomato. High-yield shed reached 25,121.9 kg in 1977 and reached 31,642.7 kg in 1978, achieving the highest yield of tomato in the whole country for two consecutive years. In 1979, it continued to reach 30,808 kg and the output value reached 3696.9 yuan, exceeding the maximum yield of 20,000 kg per mu in the Japanese greenhouse. Reached the Dutch greenhouse annual output of 2.6-3.3 kg per mu level. The fruit quality is excellent, the harvesting period is extended by 2 months compared with the general greenhouses and delayed by 1 month compared with the open field cultivation. The total harvest period is tripled. Through cultivation practices, the control indexes and cultivation of high yield environmental factors (temperature, light, moisture, etc.)
