摘要
To evaluate the effects of solar greenhouse with different structure and CO2 enrichment on illumination and temperature performance of greenhouse and cucumber growth and development in the central region of Inner Mongolia, the research used traditional solar greenhouse （A） and blanket-inside solar greenhouse（B）, and set 4 treatments： AE （traditional solar greenhouse A with CO2 enrichment）, AN （traditional solar greenhouse A without CO2 enrichment）, BE （blanket-inside solar greenhouse B with CO2 enrichment） and BN （blanket-inside solar greenhouse B without CO2 enrichment）, to explore the influence of cucumber growth, photosynthetic property, quality and yield in different structure solar greenhouses with CO2 enrichment. The results showed that the illumination and temperature in blanket-inside solar greenhouse was superior to traditional solar greenhouse, and the average light intensity in blanket-inside solar greenhouse increased by 21.05%, compared with traditional solar greenhouse. Under the condition of same greenhouse structure, stem height ,average stem diameter, contents of soluble sugar, vitamin C, net photosynthetic rate and yield showed any significant difference between the treatments with CO2 enrichment or not. Under the condition of same CO2 concentration, BE cucumber average stem height, average stem diameter, contents of soluble sugar, net photosynthetic rate and yield in BE was higher than which in AE. Therefore, the optimization in structure of blanket-inside solar greenhouse remarkably improved illumination and temperature property, combining with CO2 enrichment as application technology, there was crucial significance to promote the greenhouse performance and improve the efficiency of greenhouse vegetable production.
为明确内蒙古中部地区不同结构日光温室和增施CO_2对温室光温性能以及黄瓜生长发育的影响,以普通日光温室(A)及内保温日光温室(B)为试验温室,并设置4个试验处理:AE(普通日光温室A增施CO_2处理)、AN(普通日光温室A不增施CO_2处理)、BE(内保温日光温室B增施CO_2处理)、BN(内保温日光温室B不增施CO_2处理),分析研究了在不同结构温室中增施CO_2对黄瓜生长、光合性能、品质、产量的影响。结果表明:内保温日光温室的光照强度及温度均高于普通日光温室,内保温日光温室全天平均光照强度比普通日光温室高21.05%。在相同温室结构条件下,增施CO_2处理(AE、BE)黄瓜的株高、茎粗,可溶性糖含量、维生素C含量,净光合速率及产量均显著高于不增施CO_2处理(AN、BN)。在相同CO_2浓度下,内保温日光温室(BE、BN)中黄瓜平均株高、平均茎粗,可溶性糖含量、净光合速率及产量均显著高于普通日光温室(AE、AN)。可见,内保温温室结构的优化在改善光温条件方面效果显著,同时结合增施CO_2作为该温室的配套应用技术,对于提升温室性能及提高温室蔬菜生产效率有重要指导意义。
