摘要
以番茄“MEISHUAI”品种为试验材料,研究了廊坊市春茬番茄温室内气温的影响因素、番茄生长与温度的关系及室温调控措施。结果表明:温室内日平均气温与温室内日平均10 cm土壤温度、日平均光合有效辐射及温室外日平均气温均存在极显著相关关系,相关系数分别为0.693、0.432和0.759;番茄茎粗、株高和果实橫纵径的生长量与积温成显著或极显著正相关。针对温室内温度过高的问题,提出了具体的室外气温调控指标和调控措施。
Using tomato variety "MEISHUAI" as test material,influencing factors of temperature in greenhouse for growing tomatoes planted in spring,relationship between tomato growth and temperature,and greenhouse management measures in Langfang City were studied. Results showed that there were highly significant correlation between daily average air temperature inside greenhouse and daily average 10 cm soil temperature,daily average photosynthetically active radiation and daily average air temperature outside greenhouse,with correlation coefficients were 0.693,0.432 and 0.759(P<0.01),respectively. Stem diameter,plant height,horizontal and vertical diameter of fruit were significantly or extremely significantly positively correlated with accumulated temperature. In order to solve problem of over-high temperature in greenhouse,specific outdoor temperature control indicators and regulation control measures were proposed.
