Question

当前海南芒果施肥技术相对落后，国内外对于芒果的养分变化规律的研究也比较陈旧。为了改善芒果生产管理的落后局面，我们通过对海南省三亚市金煌芒果叶片中N、P、K、Ca、Mg、S、Fe、Mn、Cu、Zn、B等11种营养元素含量进行全年跟踪分析，较全面的得出金煌芒果叶片的养分变化规律，可将金煌芒果的生长周期分为4个阶段:营养生长期(5-9月)、生殖生长期(9-11月)、果实膨大期(11月-2月)和果实成熟期(2-4月)。各阶段叶片养分含量变化规律有所差异：营养生长期，叶片中营养元素除K含量有所下降之外，其余营养元素均有不同程度的升高：生殖生长期，叶片中的营养元素N、B、Ca含量上升，其他元素含量有不同程度的下降。果实膨大期：叶片中的N、K、Mn、Fe、Zn、B含量下降,Ca、Cu含量上升，P、S、Mg含量趋于平稳。果实成熟期：叶片中N、Mn、Fe、B、Cu含量均有不同程度增加，K、Ca、S、Zn含量有所降低。在整个生育期内，叶片中P、Mg、S、Zn等元素含量变化不大，呈锯齿状波动。本研究对于目前新的芒果栽培管理模式下营养诊断和养分综合管理都有重要的参考价值。

Hainan Mango fertilization current relatively backward technology, both at home and abroad for the changes of nutrient mango research older. Mango production in order to improve the management of the backward situation, we adopted in Sanya City of Hainan Province, golden mango leaves N, P, K, Ca, Mg, S, Fe, Mn, Cu, Zn, B and so on 11 kinds of nutrition elements for the whole year tracking analysis, to draw a more comprehensive nutrient golden mango leaves change, golden mango can be divided into the growth cycle of four phases: vegetative growth stage (5-9 months), reproductive growth period (September-November), fruit expansion 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 decline. Fruit enlargement period: the leaves of N, K, Mn, Fe, Zn, B decreased, Ca, Cu content increased, P, S, Mg content has stabilized. Mature fruit: leaf N, Mn, Fe, B, Cu content increased in varying degrees, K, Ca, S, Zn content decreased. Throughout the reproductive period, the leaves of P, Mg, S, Zn and other elements do not change, showing jagged fluctuations. In this study, the current management of the new mode of mango cultivation nutrition diagnosis and management of nutrients has important reference value.

很简单的，到谷歌网上就能翻译，以后不用出这么高悬赏了！呵呵！

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fertilization technology is relative under-developed, the research on the changes of mango nutrients has long gone out of date both at home and abroad. 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 management. 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。本回答被提问者采纳

Answer 3

The current Hainan mango applies fertilizer technical relative backwardness, domestic and foreign is also quite obsolete regarding mango's nutrient change rule's research. In order to improve the mango production management the backward aspect, we through to the Hainan Province Sanya gold bright mango leaf blade in N, P, K, Ca, Mg, S, Fe, Mn, Cu, Zn, B and so on 11 nutritive elements content carry on the annual track analysis, comprehensive obtains the golden bright mango leaf blade the nutrient change rule, may divide into the golden bright mango's vegetative cycle 4 stages: The nutrition vegetal period (May to September), the reproduction vegetal period (September to November), the fruit expands the time (in November - in February) and the fruit mature period (February to April). Various stages leaf blade nutrient content change rule has a difference: Beside the nutrition vegetal period, in the leaf blade the nutritive elements drop except the K content, other nutritive elements have varying degree elevation: The reproduction vegetal period, in leaf blade's nutritive elements N, B, the Ca content rise, other element content has the varying degree drop. The fruit expands the time: In leaf blade's N, K, Mn, Fe, Zn, the B content drops, Ca, the Cu content rise, P, S, the Mg content tends to be steady. Fruit mature period: In the leaf blade N, Mn, Fe, B, the Cu content has the varying degree to increase, K, Ca, S, the Zn content has reduces. In the entire period of duration, in the leaf blade element content changes and so on P, Mg, S, Zn are not big, assume the zigzag fluctuation. This research the nutrition diagnosis and the nutrient integrated management has the important reference value regarding the present new mango cultivation management pattern under.

Hainan Mango fertilization current relatively backward technology, both at home and abroad for the changes of nutrient mango research older. 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 decline. Fruit enlargement period: the leaves of N, K, Mn, Fe, Zn, B decreased, Ca, Cu content increased, P, S, Mg content has stabilized. Mature fruit: leaf N, Mn, Fe, B, Cu content increased in varying degrees, K, Ca, S, Zn content decreased. Throughout the reproductive period, the leaves of P, Mg, S, Zn and other elements do not change, showing jagged fluctuations. In this study, the current management of the new mode of mango cultivation nutrition diagnosis and management of nutrients has important reference value.

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 obsolete. 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 other. 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 stable. 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 extent. Within entire child-bearing period, in the blade, contents element change such as P , Mg , S , Zn seldom assume sawtoothlike form fluctuation. Both the diagnose studying cropping manages lower nutrition of pattern to at present new mango originally and nutrient general management have important reference value.
