摘要
为了研究日光温室冬季保温被揭放时间的阈值,以日出日落时间为依据,设计的揭放保温被时间为处理(H),农民经验揭放保温被时间为对照(CK),对日光温室内樱桃番茄的叶片、茎、果实的生长状况进行比较。结果表明:晴天H处理比CK光照时间长1.19 h,阴天H处理比CK光照时间长1.49 h;与CK相比,H处理使樱桃番茄的株高、茎粗较CK高;H处理使樱桃番茄净光合速率、蒸腾速率和胞间二氧化碳浓度较CK要高;H处理樱桃番茄果实的维生素C、可溶性糖、可溶性固形物含量和糖酸比均较CK高;H处理对樱桃番茄的总坐果数、单株产量以及总产量均有极显著影响,对单位面积产量具有显著影响,对平均单果质量影响不显著。该试验结果对宁夏日光温室10月底至3月初的管理具有一定的指导意义。
In order to study the threshold of time for the uncovering insulation of the solar greenhouse in winter,the time of the insulation was taken as the control(CK) based on the experience of the farmers.Based on the sunrise and sunset time,the designed insulation was taken as the treatment(H).The temperature and lighting environment inside and outside the solar greenhouse were recorded.The growth of tomato leaf,and stem fruit were compared.The results showed that H treatment was 1.19 hours longer than CK in sunny,and H treatment was 1.49 hours longer than CK in cloudy.Compared with CK,H treatment made the plant height and stem diameter of cherry tomato higher than CK.H treatment made the net photosynthetic rate,transpiration rate and intercellular carbon dioxide concentration of cherry tomato higher than CK.H treatment made the content of cherry tomato fruit vitamin C,soluble sugar,soluble solids and sugar acid were higher than CK.H treatment had a significant effect on the total number of fruit set,single plant yield and total yield of cherry tomato,and had a significant effect on the yield per unit area.The impact was not significant on single fruit weight.The results of this experiment had certain guiding significance for the management of Ningxia summer greenhouse from the end of October to the beginning of March.
