果菜立体栽培获重大突破 □ 张品 由沈阳大学园艺系李天来教授主持的国家科技部“九五”重大科技产业化项目——“主要果菜立体栽培技术研究”课题,经过数年攻关取得重大发展。番茄、茄子长季节栽培及蔬菜种苗产业化等3个技术规程,已成为指导北方日光温室蔬菜生产的重要技术依据,并示范推广16.9亩,取得经济效益4.26亿元,增加果菜产量4.03亿公斤。 李天来教授在日光温室番茄长季节栽培技术研究方面,筛选出4个年亩产2万公斤的优良品种。首先确定了日光温室长季节栽培条件下番茄植株光合速率的变化规律及其与光照强度、二氧化碳浓度、空气温度、气温等环境因素的关系,经示范实验,年亩产量超过2万公斤,优质果达95％以上,效果显著,国内尚属首创。
Significant Breakthrough in Fruit and Vegetable Cultivation □ Zhang Pin was made a major development project in the “Ninth Five-Year” major science and technology industrialization project headed by Prof. Li Tianlai from Department of Horticulture, Shenyang University. Long-term cultivation of tomatoes and eggplants and the industrialization of vegetable seedlings have become an important technical basis for guiding the production of vegetables in the solar greenhouse in northern China. Demonstration and promotion of 16.9 mu have been achieved, with an economic benefit of 426 million yuan and an increase of fruit and vegetable production of 403 million kg . Professor Li Tianlai in the greenhouse cultivation of long-term tomato technology research, screened four years to produce 20,000 kilograms of fine varieties. First of all, the changes of photosynthetic rate of tomato plants and their relationship with environmental factors such as light intensity, carbon dioxide concentration, air temperature and air temperature were determined under the condition of long-season cultivation in sunlight greenhouse. After demonstration experiments, the annual yield per mu exceeded 20,000 kg, More than 95%, the effect is significant, the country is still the first.
