Description
Technical field
The invention belongs to agricultural plantation technology fields, and in particular to a kind of method of selenium-rich rice.
Background technique
Rice is native to China, is one of world's staple food crop, and rice in China sowing face accounts for national cereal crops
1/4, and yield then accounts for more than half.The growth of rice is very fast, and 1 year at most, most then three to four months fast, breeding time existed
It 130-140 days or so, can be from germinateing, bloom, complete solid process.The time that the seed of rice stretches out young shoot only needs two or three
It, young shoot extracts leaf out, and only needs three days, therefore in the area having a moderate climate, can plant within 1 year three phase rice, and general point
For early, middle and late rice.
Selenium is the essential trace elements of the human body.Chinese Soclety of Nutrition also by selenium be classified as 15 kinds of nutrients needed by human it
One, a large amount of clinical trial both at home and abroad are bright, and human body selenium deficiency can cause the functional disturbance of certain vitals, lead to many serious diseases
Occur, the country of the whole world more than 40 in selenium deficiency area, several hundred million populations in Chinese 22 provinces all in selenium deficiency or low selenium area,
The disease incidence such as these regional population tumour, hepatopathy, cardiovascular diseases are very high.
Summary of the invention
The purpose of the present invention is to provide a kind of implantation methods of selenium-rich rice, the high water of the available Se content of this method
Rice meets the health requirements of human body.
The implantation methods of selenium-rich rice of the invention, in turn include the following steps:
(1) it chooses seeds and handles: choosing high-quality seed rice, rice paddy seed is immersed in 3-5h in the salt water that mass fraction is 1-1.2%
Afterwards, it then is placed in fungicide and impregnates 10-20min, take out later, drain surface moisture, then rinsed well with clear water, after draining,
Rice paddy seed is placed in glycerol and impregnates 1-2min, is taken out spare；
The fungicide is made of the component of following parts by weight: 3-5 parts of lysozyme, 3-5 parts of lywallzyme, wood vinegar 200-300
10-20 parts and Herba Lysimachiae foenumgraeci extract 1-2 parts of times liquid；
(2) nursery: the rice paddy seed that surface is stained with glycerol is seeded in Nutrition Soil, and the moisture content sprayed water later to soil is
70-80%；The Nutrition Soil is made of the component of following parts by weight: 100-200 parts of fermentation pig manure, 70-90 parts of cinder, selenium-rich
20-30 parts of organic fertilizer, 40-50 parts of vermiculite, river sand 30-60 parts thin, 5-10 parts of plant ash, 20-30 parts of potassium chloride, calcium superphosphate
15-25 parts and ammonium sulfate 30-40 parts；Rice seedling bed is covered with plastic film, removes film after 15-20 days, rice shoot is allowed to divulge information；
(3) rice field is handled: being laid with one layer of mixed fertilizer in the soil surface of paddy field, mixed fertilizer raw material is fermentation by weight
50-100 parts of pig manure, 80-90 parts of straw ash, 3-5 parts of sodium metasilicate, 3-4 parts of sodium selenite, per acre the mixed fertilizer in rice field be
Then 400-500kg is refined using surface soil of the rotary cultivator to rice field, be uniformly mixed soil and mixed fertilizer, soil
Earth refines with a thickness of 15-25cm, then pours water rice field, continues to pour water to be formed after making the water content of soil reach saturation degree
Then 3-5 centimetres of shoaling layer carries out secondary refinement using small-size rotary tiller；
(4) it rice transplanting and looks into seedling, fill the gaps with seedlings: carrying out uniform rice transplanting by the way of manually or mechanically, rice transplanting quantity is 20-25 ten thousand per acre
Strain carries out looking into seedling and fill the gaps with seedlings, pulls out the rice shoot not survived, and transplant new rice shoot after 5-8 days after the completion of rice transplanting in field；
(5) field management, field management include following measures:
A, water starch management, rice field is always maintained at shallow water after rice transplanting, and rice knot fringe amount reaches 70% or more, cuts off the water supply, and improves anti-fall
Volt, mitigates the harm of banded sclerotial blight, carries out rehydration before rice young panicle breaks up, then cuts off the water supply after rice knot fringe is full；
B, top dressing, in 2 leaf of rice seedling, 1 heart stage of 1 heart to 3 leaf, per hectare spreads fertilizer over the fields urea 10-15kg, potash fertilizer 60-75kg, sprays blade face
Fertilizer promotes early tiller, uniformly sprays selenium-enriched foliage fertilizer using vehicle-mounted sprayer in booting latter stage；
C, insect prevention is prevented and treated using bioanalysis, and rice field puts 30 frogs or 10 ducks in a suitable place to breed per acre；
D, diseases prevention avoids the occurrence of disease using variety diversity, sprays insecticide when necessary；
E, weeding carries out artificial or puts duck progress weeding in a suitable place to breed；
(6) it gathers in, after rice is mature, harvesting dries, cleans, then storage storage.
Wherein selenium-enriched organic fertilizer preparation method described in step (2) includes the following steps:, the root of water hyacinth is placed in matter
It measures in the sodium selenite aqueous solution that score is 2-3%, while planting algae in sodium selenite aqueous solution bottom, daily sooner or later to water
The sodium selenite aqueous solution that mass fraction is 30-40% is sprayed on cucurbit leaf, after 25-30 days, gathers in water hyacinth and algae, and cut
It is broken, after being fermented 3-5 days with Se-enriched yeast, selenium-enriched organic fertilizer is made, it is spare.

(3) rice field is handled: being laid with one layer of mixed fertilizer in the soil surface of paddy field, mixed fertilizer raw material is fermentation by weight
50-100 parts of pig manure, 80-90 parts of straw ash, 3-5 parts of sodium metasilicate, 3-4 parts of sodium selenite, per acre the mixed fertilizer in rice field be
Then 400-500kg is refined using surface soil of the rotary cultivator to rice field, be uniformly mixed soil and mixed fertilizer, soil
Earth refines with a thickness of 15-25cm, then pours water rice field, continues to pour water to be formed after making the water content of soil reach saturation degree
Then 3-5 centimetres of shoaling layer carries out secondary refinement using small-size rotary tiller；
(4) it rice transplanting and looks into seedling, fill the gaps with seedlings: carrying out uniform rice transplanting by the way of manually or mechanically, rice transplanting quantity is 20-25 ten thousand per acre
Strain is carried out looking into seedling and be filled the gaps with seedlings after 5-8 days after the completion of rice transplanting in field；
(5) field management, field management include following measures:
A, water starch management, rice field is always maintained at shallow water after rice transplanting, and rice knot fringe amount reaches 70% or more, cuts off the water supply, and improves anti-fall
Volt, mitigates the harm of banded sclerotial blight, carries out rehydration before rice young panicle breaks up, then cuts off the water supply after rice knot fringe is full；
B, top dressing, in 2 leaf of rice seedling, 1 heart stage of 1 heart to 3 leaf, per hectare spreads fertilizer over the fields urea 10-15kg, potash fertilizer 60-75kg, sprays blade face
Fertilizer promotes early tiller, uniformly sprays selenium-enriched foliage fertilizer using vehicle-mounted sprayer in booting latter stage；
C, insect prevention is prevented and treated using bioanalysis, and rice field puts 30 frogs or 10 ducks in a suitable place to breed per acre；
D, diseases prevention avoids the occurrence of disease using variety diversity, sprays insecticide when necessary；
E, weeding carries out artificial or puts duck progress weeding in a suitable place to breed；
(6) it gathers in, after rice is mature, harvesting dries, cleans, then storage storage.
