黄瓜对环境条件反应敏感,对栽培技术要求严格。特别在北方,冬季气候条件恶劣,光照时间短,温室种黄瓜一直是个难题。采用秋延后栽培的温室黄瓜,到12月中旬,常因病害严重,不得不拔秧。冬季温室黄瓜常因容易生病、产量低而不稳,耗能多、投资大、效益低,人们不愿种植。但随着人民生活水平的提高,对黄瓜的需要量日益增加,对质量要求也越来越高。所以,北方温室黄瓜的栽培技术仍需研究。近十年来,我国的地热资源被开发利用作为温室的生产能源,随着对温室内增温方法的不断改进,为冬季温室生产黄瓜,夺取高产创造了良好的条件。一、温室的结构特点利用地热增温种黄瓜,在现有的各类玻璃温室中,以单屋面温室较好,可果用如图所示的结构。
Cucumber sensitive to environmental conditions, strict requirements on the cultivation techniques. Especially in the north, the harsh climatic conditions in winter and the short illumination time have long been a problem for greenhouse cucumbers. Autumn cucumber cultivation using greenhouse cucumbers, in mid-December, often due to serious illness, had pulling rice. Cucumber winter greenhouse often due to easy to get sick, low yield and instability, energy consumption, investment, low efficiency, people are reluctant to plant. However, with the improvement of people’s living standards, cucumber needs are increasing day by day, and the quality requirements are also getting higher and higher. Therefore, the northern greenhouse cucumber cultivation techniques still need to be studied. In the recent ten years, the geothermal resources in our country have been exploited and utilized as the energy source for the production of greenhouses. With the continual improvement of temperature-raising methods in the greenhouses, good conditions have been created for the production of cucumbers in winter greenhouses and the high yield. First, the structural characteristics of the greenhouse The use of geothermal warming cucumber, in the existing types of glass greenhouse, a single roof greenhouse is better, you can use the structure shown in Figure.
