| The study takes the different light and different light time,seedling growth and cold hardiness;effects of different light on growth of pepper;effects of different light treatment time on cucumber growth;effects of different light time on tomato quality.Conclusions as follows:1.Comprehensive analysis of changes in chlorophyll content,different test materials fill under the environment of SOD activity,POD activity,CAT activity showed that in the red and blue ratio of 6:1 leek seedlings is the strongest under the low temperature environment,zucchini seedlings in the red blue ratio of 4:1 is the strongest under the low temperature environment.2.In different light quality,seedling height,stem diameter,root length compared with the control group there were significant differences.From the analysis of plant growth and appearance of different light effect on plant height,stem diameter,root length index,red blue ratio of 6:1 is the most suitable for the leek and zucchini seedlings fill measures.3.Effects of different light quality on the growth and development of green pepper,green pepper has different light quality on plant height,stem diameter,chlorophyll content of study,comprehensive analysis shows that Green pepper in the red and blue combination of 6:1 growth environment is the best.4.Study on the fill time different effects on Physiological Indexes of Cucumber,the lighting of 6h have the best effect on plant height and stem diameter effect,the best effect of chlorophyll content and fruit length of the cucumber is 8h light,through a comprehensive comparative analysis,Cucumber can achieve the most obvious economic benefits in the light of 6h.5.Effects of different light time on fruit quality of tomato,the increment of VC content in Tomato under 6h treatment was the best,the soluble solids content is the highest in light of 6h,the content of organic acids decreased by 4H treatment,Comprehensive comparative analysis,Tomato has the best quality in 6h light treatment. |
