The Seasonal Dynamic Of Biomass And Mineral Elements In Different Components Of Vaccinium Spp

The growth of plants cannot leave the mineral nutrition, in the growth of the plants in the process need to absorb the mineral elements to maintain their metabolism and growth, so the study of plant mineral elements to guide the crop production practice. This test for Vaccinium spp different components mineral elements of the growing season the dynamic changes of research, the aim is to provide the reasonable application of Vaccinium spp and quality control to provide the scientific basis. This paper with half a highbush Vaccinium Sp’ Northland’ and lowbush’Blomidon’ two Vaccinium spp cultivars as test materials, In jilin agricultural university small berries base for a unified sampling survey. In order to further study the blueberry mineral elements of the characteristics, this experimental design to detect nine mineral elements, were a large number of elements N, P, K, Ca, Mg and trace elements Fe, Mn, Zn,Cu. After Northland and Blomidon the growing season in different months on different components biomass and mineral elements and the dynamic changes of the moisture content of the results of the main test results show that:1.To compare the biomass between Northland and Blomidon which have the same components.Boimass of Northland were always higher than Blomidon,The total biomass of Northland was higher too. The biomass of taproot was the highest and the biomass of fibrous root was the lowest among the components of Northland. The biomass of annual branch was the highest and the biomass of fibrous root was the lowest among the components of blomidon.2. Mineral element content of different components of Vaccinium spp analysis:(1) N, P, K and Mn content in leaves of Northland and blomidon were significantly higher than other components.(2) Ca Mg, Fe, Cu and Zn content in the fibrous roots of Northland and blomidon were significantly higher than other components.3.Mineral element reserves of the different components of Vaccinium spp In Northland leaves in the largest reserves element is N, Ca, Mg, and reserves of the smallest element is Cu; Reserves in annual branch of the smallest element is N, Mg, Fe; Reserves in perennial branch of the largest element is P、Mn、Zn; Reserves in taproot of the largest element is K、Cu; Reserves in fibrous root of the largest element is Fe, and reserves of the smallest element is P, K, Ca, Mn, Zn. In Blomidon annual branch in the smallest reserves element is N、P、K、 Ca、Mg、Fe、Cu、Zn; Reserves in perennial branch of the largest element is Mn; Reserves in taproot of the largest element is N、P、K、Ca、Cu、Mg、Zn; Reserves in fibrous root of the largest element is Fe, and reserves of the smallest element is Mn..
