The current Hainan mango applies fertilizer the technology falls behind relatively , the go into changing law at home and abroad to mango's nutrient can't compare Aspect producing administrative falling behind for improving a mango, we analyse by the fact that N , P , K , Ca , Mg , S , Fe , Mn , Cu , Zn , 11 kind nutrition element contents such as B carry out annual tracking on Hainan province San Ya City Jin Huang mango in the blade, the nutrient reaching the Jin Huang mango blade comparatively all round changes law, but the period divides growth of Jin Huang mango into 4 stages: Nutrition growth periods (5-9 month) , reproduction growth periods (9-11 month) , fruit expand to expect (February in November) and fructescence (2-4 month) Every stage blade nutrient contents change law has institute difference: The nutrition element gets rid of K in the nutrition growth period , the blade besides contents come down to some extent , the others nutrition element has the power-up to varying degrees equally: Nutrition element N , B , Ca contents in reproducing the growth period , the blade rises , element contents have go down to varying degrees Fruit expands phase: N in blade , K , Mn , Fe , Zn , B contents come down , Ca , Cu contents rise, contents tend to become P , S , Mg Fructescence: N , Mn , Fe , B , Cu contents have equally increasing by to varying degrees in the blade , K , Ca , S , Zn contents reduce to some Within entire child-bearing period, in the blade, contents element change such as P , Mg , S , Zn seldom assume sawtoothlike form Both the diagnose studying cropping manages lower nutrition of pattern to at present new mango originally and nutrient general management have important reference

Currently Hainan mango fertilization technology is relative under-developed, the research on the changes of mango nutrients has long gone out of date both at home and Through analysing the content of N, P, K, Ca, Mg, S, Fe, Mn, Cu, Zn and B in the leaf blade of Jinhuang mango at Sanya,Hainan Province for a year around, the change rule of Jinhuang mango nutrients is botained, which is of great benefit to the improvement of the mango production The growth cycle of Jinhuang mango can be divided into four stages: The nutrition vegetal period (May to September), the reproduction vegetal period (September to November), the fruit vegetal period ( November to February) and the fruit mature period (February to April) 今天有点忙先帮你翻到这，不知道是要投稿发表的吗，如果要发表的话给你点建议，发表的摘要不能用第一人称，摘要的内容也不能太长有个字数限制好像是200字，多用被动。

加油！自力更生！自强不息！！！

Hainan Mango fertilization current relatively backward technology, both at home and abroad for the changes of nutrient mango research Mango production in order to improve the management of the backward situation, we adopted in Sanya City of Hainan Province金煌mango leaves N, P, K, Ca, Mg, S, Fe, Mn, Cu, Zn, B, such as nutrient content of 11 kinds of full - year follow-up analysis, to draw a more comprehensive mango leaves金煌changes of nutrients, may be the growth of mango金煌cycle is divided into four phases: vegetative growth stage (5-9 months), reproductive growth period (September-November ), fruit enlargement period (on November -2) and fruit maturity (2-4 months) Various stages of changes in leaf nutrient content of different laws: vegetative growth stage, leaf nutrient content in addition to decrease in K, the other nutrients increased in varying degrees: reproductive growth, leaf nutrient elements N, B, Ca content increased, other elements have different degrees of Fruit enlargement period: the leaves of N, K, Mn, Fe, Zn, B decreased, Ca, Cu content increased, P, S, Mg content has Mature fruit: leaf N, Mn, Fe, B, Cu content increased in varying degrees, K, Ca, S, Zn content Throughout the reproductive period, the leaves of P, Mg, S, Zn and other elements do not change, showing jagged In this study, the current management of the new mode of mango cultivation nutrition diagnosis and management of nutrients has important reference
