Cu, B, Mo is an essential trace element for plant growth and development, and an important influence on the yield and quality of crops. In this paper, Medicago white Longshu 3 and the Atlantic Ocean as the test material, set the control (CK), organic fertilizer (M) of nitrogen and phosphorus (NP), organic fertilizer with nitrogen phosphorus fertilizer fertilizer (M NP) four fertilizer treatments using combination of field trials, chemical analysis and biological statistical analysis method, system studies Potato Varieties Cu, B, Mo nutrient absorption Distribution of fertilization. The main results are as follows: 1. Promote the potato with the birth of the copper content of different varieties of tubers showed an upward trend in the whole plant copper content was down then up, are the highest content of harvest. Tubers and whole plant boron, molybdenum content of the overall downward trend, the lowest harvest content. Copper, boron content of each organ: leaf gt; the tubers of gt; stem, molybdenum content: tubers gt; leaves gt; stems. Fertilization did not alter the content of trends, but significantly improve the potato of organ copper and molybdenum content of different fertilizer treatments: M NP gt; M gt; the NP gt; CK. Fertilization on boron content is not significant. Potato tubers and the whole plant copper, boron, molybdenum prime accumulation was \The performance of the different varieties: Longshu 3 gt; Purple Flowers gt; the Atlantic different organs copper, molybdenum accumulation: tubers gt; blade gt; stems, boron: blade gt; tubers gt; stems. Fertilization significantly increased potato whole plant copper, boron, molybdenum accumulation of different fertilizer treatments showed as follows: the M NP gt; M gt; the NP gt; CK. With the fertility process moves forward, the proportion of potato leaves, stems Cu, B, Mo distribution reduced distribution to increase the proportion of tubers. Fertilization reduces potato stems of copper, molybdenum distribution, and increased distribution of the tubers, and to improve the distribution of boron in the stems and leaves while reducing the tubers in the distribution. Fertilization reduces the operating rate and Medicago white of different varieties of copper, boron, the Atlantic molybdenum operation rate, to increase the operation rate of the molybdenum Longshu 3. 4 different varieties of one thousand kilograms of copper production uptake, consumption coefficient: Longshu 3 gt; Atlantic gt; the Medicago white, boron and molybdenum production of one thousand kilograms uptake, consumption coefficient: Longshu 3 gt; Purple Flowers gt; Atlantic, in contrast production efficiency. Cu, B, Mo fertilization to increase the production of one thousand kilograms uptake, the effect is greater than the single application of organic fertilizer, nitrogen and phosphorus fertilizer fertilizing. Different varieties of one thousand kilograms tuber yield copper, boron, molybdenum uptake were: the Purple Flowers 3.29 g, 2.09 g, 0.11 g Longshu 3 4.43 g, 3.63 g and 0.19 g, the Atlantic 4.85 g, 1.81 g, 0.11 g, consumption coefficients were Medicago white 0.001 39,0.000 88,0.000 047, Longshu 3 0.001 49,0.001 30,0.000 062 Atlantic 0.001 48,0.000 69,0.000 043 5. potato yield and economic production of different varieties of biological performance as: Longshu 3 gt; the Medicago white gt; Atlantic. The fertilization increased rate of potato production and commodity potato increasing effect on the performance of the different fertilizer treatments: M NP gt; the NP gt; M gt; CK.
