A method of improvement many years Mango Fruit Garden acid soil produces selenium-rich mango
Technical field
The present invention relates to mango technical field of cultivation, and particularly a kind of improvement many years Mango Fruit Garden acid soil produces selenium-rich
The method of mango.
Background technique
Mango (Mangifera indica), is a kind of subtropical fruit.Mango Fruit contains sugar, protein, crude fibre,
The precursor carrotene ingredient of vitamin A contained by mango is especially high, is rare in all fruit.Secondly vitamin C contains
It measures also not low.Minerals, protein, fat, carbohydrate etc. and its main nutrient composition.Mango is one of famous tropical fruit (tree),
Because of its pulp exquisiteness, unique flavor is full of nutrition, is favored by people, so the reputation for being known as " tropical fruit king " claims.
Currently, mango is conventionally to be cultivated and managed, a kind of extremely common Different Cultivars of Mangifera indica is cultivated.
Summary of the invention
The object of the present invention is to provide a kind of method of improvement many years Mango Fruit Garden acid soil production selenium-rich mango, the present invention
Method Mango Output it is high, obtain in mango that selenium-rich content is high, improve value-added content of product.
The technical solution provided by the present invention is:
A method of improvement many years Mango Fruit Garden acid soil produces selenium-rich mango, comprising the following steps:
(1) measurement of soil acidity: in the plot of soil improvement to be carried out, along S type route, according to random, equivalent and more
The mixed principle of point acquires farming and improves the soil a layer pedotheque, the sampled point of each sample 30, by the soil of acquisition according to four points
Method leaves and takes the sample of 1kg;Soil sample is dried, pre-treatment is carried out, soil pH is detected using conventional method of analysis, obtains soil
pH;
(2) improve acid soil: as soil pH < 5.5, the soil for treating improvement spreads fertilizer over the fields 40kg/ mus of quick lime, then
Quick lime is uniformly mixed with topsoil using plough;Next year continues to spread fertilizer over the fields 20kg/ mus of quick lime, same to use plough raw stone
Ash is uniformly mixed with topsoil;The dosage of annual quick lime halves later, until the soil pH > 6.0 of soil, stops to soil
Earth spreads fertilizer over the fields quick lime;
(3) preparation of selenium solution: being watered 45kg for sodium selenite 25-45mg, and be stirred continuously 4-5min, keeps it sufficiently molten
In Xie Yushui, it is prepared into the selenium solution that concentration is 0.055-0.10%;
(4) it is filled to fruit tree and applies selenium solution: at the mango florescence, started to fill to mango fruit tree according to quantity and apply selenium solution, Er Qieshi
It filled and applies 1 time every 7-10 days, listed in mango and stop within first 15 days spraying;
(5) selenium solution is sprayed to fruit: in Mango Fruit forming, starting to spray selenium solution to Mango Fruit according to quantity, and
And be to be sprayed every 5-6 days 1 time, it is listed in mango and stops within first 15 days spraying;
(6) other are managed: other liquid manure discharge and the prevention and control of plant diseases, pest control conventionally carries out.
Preferably, the soil ratio that conventional method of analysis is 2.5:1 in step (1) impregnates pH meter.
Preferably, the concentration of selenium solution is 0.055% in step (4).
Preferably, the concentration of selenium solution is 0.10% in step (5).
Compared with prior art, the device have the advantages that it is as follows:
The Mango Output that method of the invention obtains is high, obtains the Se content in mango in 0.085mg/kg or more, symbol
DB 45/T1601-2014 Se-rich farm products Se content classificating requirement is closed, improves value-added content of product, and then improve product
Market value.
