Abstract
A kind of implantation methods of selenium-rich upland rice of the present invention, Se content is the 0.20 ㎎/㎎/㎏ of ㎏~0.25 in the rice planted, and organic selenium content reaches 85%~90%, and the usage amount of selenium-enriched foliage fertilizer reduces by 100%~300%.Selenium-enriched foliage fertilizer is sprayed application into rice leaf at upland rice earing flowering initial stage, spray 90% or more inorganic compound containing selenium can be made to be converted into organic selenium in rice, can effectively improve the Se content of rice；10 days~15 days before upland rice earing flowering initial stage, to manganese element foliar fertilizer of upland rice foliage-spray, rice stem, the selenium element in leaf can be promoted to shift to Rice Panicle；It earths up after spraying a selenium-enriched foliage fertilizer, the filling rate of upland rice can be increased with lodging-prevention, shift to an earlier date upland rice 5 days~10 days mature, volume increase 10%~15%.
Description
Technical field
The present invention relates to agricultural plantation technology fields, and in particular to a kind of implantation methods of selenium-rich upland rice.
Background technique
Selenium can improve human immunity, promote the proliferation of lymphocyte and the synthesis of antibody and immunoglobulin.Selenium is to colon
The kinds cancers such as cancer, cutaneum carcinoma, liver cancer, breast cancer have the function of significantly inhibiting and protect, in machine intracorporal intermediate generation
Thank to product methyl enol with stronger anticancer activity.The nutrients such as selenium and vitamin E, allicin, linoleic acid, germanium, zinc have
Oxidation resistant effect is cooperateed with, antioxidant activity is increased.Meanwhile selenium has the function of mitigating and alleviating heavy metal toxicity.Scientific circles
The study found that the height of blood selenium level and the generation of cancer are closely bound up.A large amount of survey data explanation, a regional food and soil
The height of Se content has direct relation with the disease incidence of cancer in earth, such as: the Se content in the food and soil in this area is high,
The morbidity and mortality of cancer are with regard to low, conversely, the cancer morbidity and the death rate in this area are just high, the fact illustrates selenium and cancer
The generation close relation of disease.Scientific circles also identify selenium with pre- anti-cancer effect simultaneously, are that body trace element is " anti-
The king of cancer ".Staple food of the rice as world population, is the main source of human body selenium, and the height of rice Se content directly influences
The nutrition condition of human body selenium.
It generallys use during Rice Cropping and sprays the foliage organic fertilizer containing selenium and obtain Rice enriched-Se, and use this method kind
The content of the selenium-rich rice of plant, each organ selenium of the rice plant in maturity period is successively successively decreased from stem, leaf, fruit, it is known that the plantation is rich
The method of selenium rice obviously without effective and reasonablely using selenium-rich rice plants stems, the selenium element in leaf, the usage amount of selenium fertilizer compared with
Greatly, high production cost.
Summary of the invention
In view of the deficiencies of the prior art, a kind of the object of the present invention is to provide planting costs low, meter Zhi Hao, Se content are high
The implantation methods of selenium-rich upland rice.
To achieve the goals above, The technical solution adopted by the invention is as follows: a kind of implantation methods of selenium-rich upland rice, selenium-rich
The Se content of soil is 0.3mg/kg~0.5mg/kg in dry-rice land, 10 days~15 days before upland rice earing flowering initial stage,
To manganese element foliar fertilizer of upland rice foliage-spray, manganese element content is 35 ㎎/L~50 ㎎/L in the manganese element foliar fertilizer；
At upland rice earing flowering initial stage, to selenium-enriched foliage fertilizer of upland rice foliage-spray, selenium element content is in the selenium-enriched foliage fertilizer
12 g/L~20g/L；It earths up within 7 days~12 days after spraying a selenium-enriched foliage fertilizer, the height of ridging is the ㎝ of 5 ㎝~8.
Preferably, the manganese element foliar fertilizer is by containing manganese sulfate monohydrate and magnesia amount ratio by weight are as follows: 1: 0.3~
0.5 composition.
Preferably, the dosage of the manganese element foliar fertilizer is 50 kgs/acre~80 kgs/acre.
Preferably, the selenium-enriched foliage fertilizer is by inorganic compound containing selenium and phosphate amount ratio by weight are as follows: 3: 5~8
Composition.
Preferably, the dosage of the selenium-enriched foliage fertilizer is 80 kgs/acre~100 kgs/acre.
Preferably, the inorganic compound containing selenium be sodium selenate, sodium selenite, potassium selenite, potassium selenate, ammonium selenite and
One of ammonium selenate is a variety of.
Preferably, the phosphate is potassium dihydrogen phosphate, sodium dihydrogen phosphate, ammonium dihydrogen phosphate, magnesium monohydrogen phosphate, phosphoric acid hydrogen two
One of ammonium, dipotassium hydrogen phosphate and disodium hydrogen phosphate are a variety of.
Preferably, the height of the ridging is 6.5 ㎝.
A kind of implantation methods of selenium-rich upland rice of the present invention, Se content is 0.20 ㎏~0.25 ㎎/in the rice planted
㎎/㎏, organic selenium content reach 85%~90%, and the usage amount of selenium-enriched foliage fertilizer reduces by 100%~300%.In upland rice earing flowering
Selenium-enriched foliage fertilizer is sprayed application to rice leaf by initial stage, and spray 90% or more inorganic compound containing selenium can be made to be converted into rice
In organic selenium, can effectively improve the Se content of rice；10 days~15 days before upland rice earing flowering initial stage, to upland rice blade face
Spray a manganese element foliar fertilizer, rice stem, the selenium element in leaf can be promoted to shift to Rice Panicle, make stem in upland rice, leaf,
The selenium content of fruit remains basically stable, and can effectively improve the Se content of rice, so that making the usage amount of selenium-enriched foliage fertilizer reduces
200%~300%；It earths up within 7 days~12 days after spraying a selenium-enriched foliage fertilizer, the grouting speed of upland rice with lodging-prevention, can be increased
Rate shifts to an earlier date upland rice 5 days~10 days mature, volume increase 10%~15%.
