Study On Soilless Potted Seedlings Techniques And Physiological Characteristic Of Viburnum Opulus L.

Viburnum opulus L. is belong to caprifoliaceous viburnum Linn. It is cluster deciduous small shrubs.Its has high ornamental value. It has green leaves, white flowers and red fruits. It can be plant in forest edge, the edge of grasslands, roadside and the north of building. It has different degree of smoke pollution resistant capability, afforest in factories and mines. Viburnum opulus L. also has medicinal value, plants contain chlorogenic acid, ursolic acid,β-sitosterol and flavonoids and other inqredients. This paper studies about Viburnum opulus L. potted, with abundant cultivated form of Viburnum opulus L., expand the scope of application, can efficient rapid propagation.This experiment uses the cutting seedling of Viburnum opulus L.as test material. Through orthogonal design setup three factors are the formula of nutrient, the formula of matrix and the way of watering in greenhouse conditions.The experiment adopts orthogonal design, setup three factors are the formula of nutrient, the formula of matrix and the way of watering. Each factor is three levels. Determine morphological indexes and physiological indexes include leaf length plus width, yearly growth of plant high, the chlorophyll content and the content of chlorogenic acid, photosynthetic rate and stomata conductance, the content of mineral elements in leaf, physical and chemical properties of matrix etc in each treatment combinations. And use these indicators for visual analysis and variance analysis of orthogonal test. To determine the main influence factors of Viburnum opulus L.soilless cultivation. To find the best level. Provide scientific theory better to implement the Viburnum opulus L. soilless cultivation.1. The results of Viburnum opulus L.'leaf length plus width under different treatment: the best ingredients are one Caotan plus one Taoli as the matrix, spraying over plants and matrix as the way of watering and Hoagland and Snyde as the nutrient solution. Matrix solution plays a great role in determining the leaf length plus width which demonstrates great differences if the matrix solutions are different.2.The results of Viburnum opulus L.' yearly growth after testing under different treatment:the best ingredients are Hoagland and Snyde as the nutrient solution, spraying over plants and matrix as the way of watering and one Caotan plus one Zhishi as the matrix. Nutrient solution plays a great role in determining the growth of plants which demonstrates great differences if the nutrient solutions are different.3.The results of Viburnum opulus L.'photosynthetic rate under different treatment:the best group is spraying water over plants and matrix as the means of watering, Japanese Yuanshi formulation as its nutrient solution, one Caotan plus one Taoli as the matrix.4.The results of stomata conductance of Viburnum opulus L.' blade under different test conditions:the best effect comes from the combination of Japanese Yuanshi formulation as the matrix solution, spraying water over matrix as the way of watering and one Caotan plus one Taoli as the matrix.5. The test results of the content of chlorophyll in Viburnum opulus L. under different test conditions:the group that produces highest content of chlorophyll is the combination of Hoagland and Snyde as the nutrient solution, one prelate plus one Taoli plus one Caotan plus one Zhi shi as the matrix and spraying water over plants and matrix as the way of watering. The highest content is 0.399mg/g.6. The test results of the content of neochlorogenic acid in Viburnum opulus L.'blades: the greatest positive effect comes from the combination of spraying over the plants and matrix as the way of watering, one Caotan plus one Zhishi as the matrix and Hoagland and Snyde formulation as the nutrient solution.7. The test results of the content of mineral in Viburnum opulus L.'blades in different seasons:the content of N, P, K, Ca, Mg in Viburnum opulus L.'blades should be listed as N, K, P, Ca and Mg from the highest to the least. The content of N, P and K comes to the peak in the summer and then begins to decrease. The content of Ca is almost the same with N; the difference is that the tendency of decreasing is not very obvious with Ca. In contrast, the content of Mg comes to the bottom before and after summer time.8. The test results of the physical and chemical features of the three matrixes:Among the three different matrixes, one Caotan plus one Zhishi is most suitable for porosity; it's total porosity comparison modest. The greater density matrix is suitable for the soilless cultivation Viburnum opulus L.'growth.Due to matrix density is large; the root of the plant fixed effect is good.
