Study On The Relationship Between The Growth Of Leaves And Fruits Of Temperature And Light Environment Of Tomato In Solar Greenhouse

In this study,under the condition of pure temperature and light in the dredged solar greenhouse,the changes of temperature and light environment and the effect on the growth of tomato cultivar ‘St.Semines313’ as material were studied.The indoor temperature,indoor and outdoor air temperature,indoor and outdoor light radiation,etc.,collected regularly from September 2015 to January 2016 in autumn and from March to July in the spring of March,2006,were collected according to the growth period.The results showed that the effects of temperature and light conditions on the growth and development of tomato were studied.The main results are as follows:1.The lowest temperature during the production of tomato in the greenhouse was 11,and the maximum temperature difference was 22.15℃.In the normal sunny daylight,the indoor average temperature is about 20 ℃,indoor and outdoor daily temperature temperature difference above 15 ℃;see the light hours of the average temperature of the highest temperature can reach 27.5℃;day accumulated temperature at 200℃,5 cm also 10 ℃above,tomato can grow normally.Spring tomatoes,the lowest temperature in the early stage are above 10℃,the daily mean temperature difference of 12 ℃,the ground temperature above 10℃.The trend of light radiation inside and outside the greenhouse is basically the same,except for the autumn crop in mid-November to the end of January haze weather caused by the continuously cloudy days.The base can meet the normal growth needs of tomatoes.5cm slightly higher than 10 cm ground temperature,the tendency is basically the same,with the indoor temperature changes.2.During the growth period of tomatoes,there was a significant positive correlation between the average temperature and the daily growth of tomato during the squaring stage,fruit setting stage,and early stage of fruiting period have a certain relevance.Results the mean temperature,accumulated temperature and daily mean temperature were positively correlated with the daily increment of internode,which was correlated with a night temperature.There was a significant correlation between the diurnal temperature and the daily accumulated temperature of tomato in the early days of the fasting period and the daily growth of tomato internode.The median temperature,the daily mean temperature and the daily mean temperature was positively correlated with the daily mean temperature And the length of the internode is not significant.There is a reliable correlation between the temperature of spring and autumn and the daily increment of internode.3.There was a significant positive correlation between daily mean temperature and daily leaf temperature,and the increase in leaf area was not significant.The light radiation was also positively correlated with leaf area.There was a significant positive correlation between the mean daily mean temperature and the leaf area increase,and positively correlated with the daily accumulated temperature,and had a precise correlation with the night temperature.The correlation between mean daily mean temperature and leaf area increase was higher than that of autumn stubble,but the correlation between daily temperature and night temperature was lower than that of the autumn crop.There is a definite correlation between ground temperature and leaf area increase.4.There was a significant positive correlation between the increase of the diameter of the tomato in the autumn crop and the daily mean temperature,which was positively correlated with the daily mean temperature and the daily temperature in the light hour,and had a certain correlation with the night temperature.There was a significant positive correlation between the mean temperature and mean daily temperature,which was positively correlated with daily accumulated temperature and correlated with night temperature.In addition to the light our hours are warm,the autumn stubble tomato fruit diameter and other factors have a higher correlation than the spring crop.Fruit diameter and ground temperature have a specified correlation but not significant.5.There was a positive correlation between the budding period,the fruit setting period and the initial stage of the fruit and fruit,and the results were later correlated with the optical radiation,but not as significant as the other three periods.The correlation between the soft radiation and the daily increment of the intercropping was also higher than that of the spring crop.6.in the next digging greenhouse tomato autumn crop management process,especially in winter early spring as the highest possible to improve the lighting conditions within the facility,the appropriate fill light,to ensure adequate heat.Should attach great importance to stem and bold growth,rapid expansion of leaf area,is conducive to the expansion of the fruit.Proper control of night temperature,reduce plant respiration,help to improve tomato fruit yield.7.During the experiment,the temperature and night temperature was correlated with tomato growth and development,but not significant.The temperature is related to the temperature in the greenhouse.The night temperature is related to the nighttime heat preservation and the heat storage in the greenhouse.It is also necessary to pay more attention to the regulation of the insulation to promote the sound growth of the tomato.
