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。
In order to clarify the effects of solar greenhouse with different structure and CO_2 addition on the growth and development of cucumber in the central region of Inner Mongolia, the greenhouse was constructed by using ordinary sunlight greenhouse (A) and internal insulation greenhouse (B) as experimental greenhouse. Four experimental treatments : AE (normal sunlight greenhouse A plus CO_2 treatment), AN (normal sunlight greenhouse A without CO_2 treatment), BE (inner insulation greenhouse B plus CO_2 treatment), BN Treatment), the effects of CO 2 supplementation on the growth, photosynthetic characteristics, quality and yield of cucumber in different greenhouse were analyzed. The results showed that the light intensity and temperature of the solar greenhouse were all higher than those of the ordinary solar greenhouse, and the average light intensity of the greenhouse was 21.05% higher than that of the solar greenhouse. Under the same greenhouse conditions, the plant height, stem diameter, soluble sugar content, vitamin C content, net photosynthetic rate and yield of CO 2 -treated (AE, BE) cucumber were significantly higher than those without CO_2 treatment ). Under the same CO_2 concentration, the average plant height, the average stem diameter, soluble sugar content, net photosynthetic rate and yield of cucumber in the solar thermal greenhouse (BE, BN) were significantly higher than those in the normal sunlight greenhouse (AE, AN). It can be seen that the optimization of the structure of the internal insulation greenhouse has a significant effect in improving the light and temperature conditions. Combined with the application of CO2 as an applied technology in the greenhouse, it is of great guiding significance for improving the greenhouse performance and improving the greenhouse vegetable production efficiency.
