Studies On The Contents Of The Mineral Nutrition Of Zao Hei Bao Grape Cultivating Under Greenhouse And The Correlation Among The Element

The variation of the contents of the mineral nutrition of zao hei bao grape cultivating under greenhouse in different films and training were measured during the period of growth. The results are as follows:(1).In greenhouse, the dynamic variation of the contents of the mineral elements of leaves of the grape are basically identical ,but the contents of the mineral elements are different. During the period of growth, the contents of Cu , K in greenhouse are higher than those of the open grand, the contents of Mn , Zn , Ca in the open grand are higher than those of the greenhouse. The variation of the contents of Fe , Mg are no regular.(2).The results indicate that different training can affect the metabolize of mineral elements in greet degree. In all, the contents of the mineral nutrition of the grape in the level training branch of double hedges are higher than that of the erect training branch of single hedge.(3).The results indicate that different films can affect the metabolize of mineral elements in great degree. In all, the contents of the mineral nutrition of the grape in the blue film are higher than that of the write film.(4).The results indicate that unveiling the film in time is good for the color and the maturing in greenhouse.(5)The analysis of the correlation indicate that there are different degree of correlation among the mineral nutrition. There are synergism among Ca , Mg, Fe, Mn, Zn , There are antagonistic effect among K , Cu and other five elements. So scientific cultivation and rational manuring are very important.In the test, the metabolize regularity of the mineral nutrition of Zao Hei Bao grape in different films and training was studied, and the new theoretical evidence was provided for the grape cultivating under greenhouse.
