Effects Of Berry Loading On Mineral Nutrition In Vitis Viniferal L. Cabernet Sauvignon With "厂" Shape Training System

In order to improve the quality of wine grape at eastern foot of Helan Mountain, in the test Cabernet Sauvignon (Vitis viniferal L. Cabernet Sauvignon) as test material, study different tree body load processing of Cabernet Sauvignon grape beads plant mineral element content and leaf photosynthesis and berry quality of influence. The results show that:1."厂" training system, with the increase in the amount of load grape leaves chlorophyll content will be increase, the net photosynthetic rate of leaves and grape load is positively correlated.2."厂" training system,0.5 kg/cm2 in grape leaf N, P element content is significantly higher than control,0.75 kg/cm2 load processing grape leaf N significantly lower than that of CK. CK is significantly higher than K element in "Dulong" tendril. CK of Ca, Mg element content in the leaves was significantly lower than "Dulong" tendril",0.5 kg/cm2,0.75 kg/cm2 loading and "dulong". There is no significant difference between Ca and Mg content.3.This experiment,0.25 kg/cm2,0.5 kg/cm2,0.75 kg/cm2 loading of grape leaves significantly higher than that of Fe element in the "Dulong" training system alone, and significantly reduce with the increase of load.0.25 kg/cm2,0.5 kg/cm2 Mn element content in the leaf blade is significantly higher than "Dulong" training system blade in Mn content,0.75 kg/cm2 load and "dulong shoots".0.25 kg/cm2, 0.5 kg/cm2,0.75 kg/cm2 grape leaf load is significantly higher than the zinc element in the "dragon tendril" alone, and with the increase of load.4.The different treatment of " 厂" training system, compared with "Dulong" training system N elements content in berry has a tendency to rise, but there was no significant difference.0.75 kg/cm2 P element content in berry was significantly lower than "Dulong" training system, CK,0.5 kg/cm2 load and "Dulong" training system, there was no significant difference between treatment will reduce with the increase of load. CK berry K element content is significantly higher than "Dulong" training system, 0.5 kg/cm2,0.75 kg/cm2 K content in berry was significantly lower than "Dulong" training system.5.Ca will decrease with the increase of load and fruit, and a significant difference between different processing, and the berry of Mg, Fe, no obvious regularity, berry Mn, zinc will decrease with the increase of load. For Cabernet sauvignon grape berry quality, under the "factory" glyph, cabernet sauvignon grapes, soluble sugar, tannin and total phenol content and decreased with the increase of loading.Comprehensive leaf photosynthesis, leaf and berry and berry quality, content of elements in Cabernet sauvignon grapes "厂" training system to 0.5 kg/cm2 loading to the appropriate level.
