Dynamics Studies On The Mineral Characteristics Of Three Blueberry Cultivars In Jilin Province

This studies was began from2010to2013in Jilin province, and collected a large number of different blueberry cultivar leaves in eight area, including Changchun, Liuhe, Jingyu, Songjianghe, Tonghua, Linjiang, Antu, Liudaogou. For the studies cultivars about eight kinds of blueberry including Northland, Bluecrop, Blomidon, Northcountry, St. cloud, Polaris, Northblue, Elliott, eight kinds of blueberry. For the studies on Northland, Bluecrop, Blomidon in2010,2011,2012. The experiment was taken every ten days from the middle of July to the middle of September last three years. Including the growth potential and for each cultivar of mineral nutrition on leaf and soil.The results are shown below:1With the growth of plants,It can be concluded that the dynamic studies on mineral element content of three cultivars. The N, P elements was tend to down. The K, Ca, Fe elements was tend to up. The Zn, Cu, Mg elements Change is not obvious. The Mn element have no regularity.2Through the dynamics studies on the growth and mineral characteristics of Blueberry can be concluded:The elements consistent have the same change between leaves and soil of Blomidon contains:K showed the trend of decline after the rising of, Ca showed the trend of the wave after decline, Fe showed the trend of the wave after rising; The elements consistent have the same change between leaves and soil of Northland contains:N has been downward trend, P and K all showed a trend of steady after decline, Fe showed the trend of decline after the rising; The elements consistent have the same change between leaves and soil of Bluecrop contains:N has been downward trend, K showed a rising trend of greater volatility, Mg showed a downward trend of greater volatility, Zn showed a "M" trend.3The leaf analysis standard of main elements in three cultivars:Blomidon leaf analysis standard: N:1.86%～2.03%, P:0.09%～0.15%, K:0.17%～0.41%; Northland leaf analysis standard N:1.62%～2.09%, P:0.08%～0.08%, K:0.21%～0.45%; Bluecrop leaf analysis standard N:1.78%～2.13%, P:0.08%～0.08%, K:0.33%～0.66%.4The leaf analysis standard of main elements in Jilin province of cultivars was N:P:between1.71%2.03%0.15%0.28%, K:0.26%to0.44%.5According to the mineral status quo of eight cultivars in Jilin province, It can be concluded the most suitable planting regions for each species:Blomidon-Baishan, Northland-Songjianghe, Bluecrop-Changchun, Northcountry-Antu, Polaris-Songjiangh、Antu, St. cloud-Tonghua、Antu, Northblue-Jingyu、Baishan, Elliott-Tonghua、Jingyu、Linjiang.
