The planting method comprises the steps of seed soaking, seedling culture, rice seedling transplanting, irrigation, fertilization, disease and insect pest control, selenium fertilizer fertilization, weeding and harvesting. According to the planting method of the selenium-rich paddy rice, through effective treatment on seeds, by matching with fertilizer selection, disease and insect pest control and reasonable selection of weeding mode, the planting yield of the paddy rice is raised; particularly due to the fertilizer selection, a fertilizer is easy to absorb, nutrition of the paddy rice is ensured mainly through the organic fertilizer, disease prevention can be facilitated, no pollution to the environment is caused, the cost is lowered, the paddy rice yield is raised, and paddy rice development is promoted; the dosages of other pesticides are few, the paddy rice is green, environment-friendly and pollution-free and has no drug residual, and the safety of an eater is guaranteed; in addition, the dosage of used selenium raw material is few, the cost of the whole production process is low, produced rice has high nutritive value and is high in selenium content, and ordinary rice is turned to highly distinctive functional food.
Description
Technical field
The present invention relates to agricultural technology field, and in particular to a kind of implantation methods of Selenium rich rice.
Background technology
Oryza sativa L., is annual gramineae plant, high about 1.2 meters, leaf length and it is flat, panicle is made up of many small ears.Institute
Knot reality is Oryza glutinosa, claims rice or rice after shelling.Oryza sativa L. can be divided into long-grained nonglutinous rice and Jing rice, early rice and middle late rice, Oryza sativa L. var. glutinosa Matsum. and non-glutinous
Rice.
Oryza sativa L. is one of long staple food crop of China's cultivation history.Rice is of high nutritive value, good palatability, easily
Digestion, is not only the main food of China, also there are about half population in the world with rice as staple food.Oryza sativa L. side-product purposes is wide
General, its Testa oryzae is both the concentrated feed of domestic animal, and medical material, and rice husk can be used as the raw material of industry, and Caulis et Folium Oryzae is except can cook feed stripped
Outside Edible Fungi raw material and organic fertilizer, or the raw material of paper industry etc..Therefore, develop Rice Production, improve rice
The quality of the yield rice of paddy, is of great significance to the development tool of Chinese national economy.
China is healthy and safe as the national physique of large agricultural country, the yield of Oryza sativa L. and safe direct relation, but existing
Some paddy rice planting method yield is relatively low, it is impossible to meet the needs of growing agricultural, and the water planted in prior art
, there is certain harm to the health of consumer to a certain extent in the residual component containing pesticide that rice has.
The content of the invention
It is an object of the invention to provide a kind of implantation methods of Selenium rich rice, can improve the plantation yield of Oryza sativa L., pesticide
Consumption is few, green, environmentally friendly, pollution-free, drug residue free, it is ensured that the safety of eater.
The technical scheme for realizing the object of the invention is：
A kind of implantation methods of Selenium rich rice, comprise the steps：
（1）After by rice paddy seed in the sun dry in the sun 3-5 days, rice paddy seed is put in saline and is soaked, then use clean water
1-2 time；Then sterilized with disinfectant, pull out and rinsed well with clear water again, then 10-12h is soaked in 30-32 DEG C of clear water, so
Afterwards soaked rice paddy seed is put and carry out in the sun accelerating germination；
（2）Rice shoot is cultivated in rice field first, pig manure 120-160kg, nitrogen-phosphorus-potassium compound fertilizer 18-22kg is applied in every mu of rice seedling bed, then is spread
Lower seed rice, when rice shoot grows tall about 8cm, then carries out transplanting rice transplanting；
（3）Before rice transplanting during site preparation, in soil per mu apply well-rotted farmyard manure 500-700kg, calcium superphosphate 40-60kg,
Ammonium sulfate 15-20kg, is deep ploughed with reference to fertilising, and tilling depth is 25-30cm, line-spacing 30-32cm, the rice transplanting water filling of hill spacing 20-22cm,
Depth of water 1-2cm；
（4）Water filling again after transplanting 15-20 days, depth of water 3-5cm fill shallow water daytime, and fill profundal zone in the evening；
（5）12-15 days after rice transplanting, topdressed using paddy rice-dedicated fertilizer；
（6）Pre- preventing disease and pest, is sowed on plant with plant ash when there is pest and disease damage；
（7）In the Oryza sativa L. booting stage, per 7-10 days, feedwater rice seedlings were filled and apply a selenium solution；It is in Grain Filling, every to spray within 5-6 days
Selenium solution, stops spraying in Oryza sativa L. for ripe first 15 days；
（8）Note weeding, nearby shallow hoe, it is deep at a distance to uproot, in order to avoid hinder root；
（9）Hang down when spike of rice, it is golden yellow full when, it is possible to gathered in.
Step（1）The saline, it is 1 by Sal and water in mass ratio to be:4 ratio is mixed.
Step（1）The disinfectant, is the imidacloprid with the cleer and peaceful mass fraction of bacterium worm 5%, after mixing plus a small amount of water is slurred
Pasty state, is subsequently adding clear water, and uniform dilution is obtained, and it is 1 that the cleer and peaceful mass fraction of bacterium worm is the mass ratio of 5% imidacloprid and clear water:
1.2:500。
In step (2) nitrogen-phosphorus-potassium compound fertilizer, the weight ratio of N P and K is 1-1.2:0.5-0.7:0.8-1.
Step（5）It is described to topdress, it is made up of the raw material of following weight portion meter：Corn germ cake 20-30 parts, Borax 1-3 parts,
Maifanitum 6-8 parts, potash fertilizer 1-3 parts, plant ash 10-12 parts, phosphate fertilizer 1-3 parts, zinc sulfate 1-3 parts, carboxymethyl cellulose 6-8 parts,
Nitrogenous fertilizer 10-20 parts；Preferably, it is described to topdress, it is made up of the raw material of following weight portion meter：25 parts of corn germ cake, 2 parts of Borax,
7 parts of Maifanitum, 2 parts of potash fertilizer, 11 parts of plant ash, 2 parts of phosphate fertilizer, 2 parts of zinc sulfate, 7 parts of carboxymethyl cellulose, 15 parts of nitrogenous fertilizer.
Step（7）The preparation method of the selenium solution for spraying is：25-30mg sodium selenite is watered into 45-50kg, not
Disconnected stirring 4-6min so as to the selenium solution that concentration is 0.055-0.065% is formed in being completely dissolved in water.
Compared with prior art, the invention has the beneficial effects as follows：The Selenium rich rice implantation methods of the present invention, using to seed
Effective process, coordinate the kind that Oryza sativa L. is improve to the reasonable selection of the selection of fertilizer, the preventing and treating of pest and disease damage and weeding system
Plant the selection of yield, especially fertilizer so that fertilizer easily absorbs, it is main to ensure the nutrition of Oryza sativa L. using organic fertilizer and prevent
Disease, will not be to environment, and not only reduces cost, improves rice yield, promotes Development of Rice；And other pesticide dosages
It is few, green, environmentally friendly, pollution-free, drug residue free, it is ensured that the safety of eater.Meanwhile, the selenium raw material dosage for using is few, entirely
Production process low cost, but the rice produced not only nutritive value is enriched, and Se content is high, becomes common rice
A kind of functional food of extremely characteristic.
