Description
Technical field
It is more particularly to a kind of to exempt to transplant the strong seedling cultivation of rice side of tillering ability the present invention relates to agricultural plantation technology field
Method.
Background technology
Paddy rice originates in Tropical Asian, is annual gramineae plant, 24 chromosomes.After China widely plants, gradually
Travel to all over the world.Paddy rice ties title rice or rice after the grain of rice shells.Nearly half population, is food all with rice in the world.Greatly
The eating method of rice is varied, there is rice, congee, rice cake, rice cake, rice noodles rice wine etc..Paddy rice can also make shallow lake in addition to edible
Powder, wine brewing, vinegar processed, rice bran can be refined sugar, extracts oil, extract furfural, and for industrial and pharmaceutical, rice husk, rice straw also have many use.I
State paddy rice main producing region is mainly the Northeast, the Yangtze river basin, Pearl River Delta.Paddy rice happiness high temperature, how wet, short-day, will to soil
Ask not tight, rice soil is best.
The Genus Oryza system of fibrous root, adventitious root is flourishing, and fringe is panicle, self-pollination.It is annual cultivation cereal.Stalk is straight
It is vertical, 30~100cm high.The row alternate of leaf two, wire lanceolar, tip of a leaf film quality, 2 split.Panicle is loose；Small ear Long Circle, two
Side pressure is flat, and containing 3 little Hua, clever pole is degenerated, only mark, and top little Hua both sexes, lemma boat-shaped has awns；Stamen 6；2 flowers degenerate only
Lemma is stayed to be located under hermaphrodite flower, constant error takes lepicena as.Caryopsis.Originate in China.It is one of world's staple food crop.China
Rice growing face accounts for the 1/4 of national cereal crops, and yield then accounts for more than half.Cultivation history is existing 14000~18000 years.
It is important cereal crops；In addition to edible caryopsis, can starch processed, wine brewing, vinegar processed, rice bran can be refined sugar, extracts oil, extract furfural, for work
Industry and pharmaceutical；Rice straw is good feed and paper making raw material and braided material, and rice sprout and rice root can hyoscines.
Because in Anhui northern area Rice Cropping, climate influence cultivates paddy rice sowing quantity greatly, increases peasant at present
Originally, while the disease resistance extreme difference of paddy rice, applying pesticides are also easy to produce poisoning for production, while very big edible safety problem is there is also,
All it is first nursery in addition during conventional rice cultivating, through cultivating seedling to improve the resistance of paddy rice and reducing production cost
Seedling, then the step of transplant, and it is disclosed by the invention it is a kind of exempt to transplant the strong paddy seedling culture method of tillering ability, only need to through nursery,
Cultivate the problems such as to improve the resistance and cost during Rice Cropping, save the cultivation rice shoot of intermediate steps.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, exempt to transplant the strong seedling cultivation of rice of tillering ability the invention provides a kind of
Method.
The technical solution adopted in the present invention is：
A kind of to exempt to transplant the strong paddy seedling culture method of tillering ability, its method for culturing seedlings comprises the following steps：
(1) in field mu organic fertilizer 2000-2400kg, and soil deeptillage 30-35cm, surface soil is dried, makes topsoil
Water content is 18-22%, is then applied in soil surface and removes biogas slurry, and mu applies biogas slurry 3000-3600kg, and soil 30-35cm is ploughed deeply again
Afterwards, it is 18-22% to continue to shine 3-5 angels Soil reference materials, and soil of then raking makees seedbed, and paving 3- is then padded on seedbed
5mm is thick, length for 1-2cm becomes thoroughly decomposed crushing straw, paving thickness is the seedling medium of 2-4cm thereon；
(2) choose high-quality seed rice, after going the removal of impurity, with heavy caliber container contain frozen water, seed rice is uniformly removed in the water surface by its from
So sink, the flat shell bubbled through the water column is pulled out immediately, then allows the full seed rice being sunken in water that 2-3h is soaked in frozen water；
(3) seed rice after being soaked through step (2) frozen water takes out to pave and is dried in the air ventilation in the moon, drains seed rice surface moisture, seed rice stand
Paving thickness is 3-5mm, is degree not overlapped between seed rice, and environment temperature is 30-34 DEG C, and wind speed is 6-8m/s, carries out the moon and dries in the air 6-8h；
(4) in the seed rice after step (3) treatment being placed on into temperature for 28-32 DEG C, the environment that humidity is 42-48%, uniformly pave
On burlap, paving thickness is 4-6mm, burlap is immersed in nutrient solution surface, seed rice clear water was taken out before 7 points of every morning and is washed in a pan
Wash once, nursery by seed rice grows gemma after 5-7 days；
(5) compound seedling medium water content on seedbed is reached saturation, and outwards do not seep water, then the seed rice after sprouting uniformly is removed
Turn on the seedling medium in seedbed, seed rice gemma is covered with plant ash, shed is then built on seedbed, rice shoot is treated after 5-7 days
Length is high to 7-10mm, controls compound seedling medium water content for 40-60%, and daily 11 point 30-14 points 30 are opened shed two ends and led to
Wind, rice shoot is long high to 3-4cm after 15 days, removes shed, and, in 35-40%, rice shoot is long to 5- after 7 days for control compound seedling medium water content
6cm, can cultivate paddy rice.
Further, the seedling medium described in step (1) is made up of following raw material：Sandy soil 16-20 parts, mud
20-26 parts, biogas residue 20-26 parts, N-P-K content be composite fertilizer 1-3 part of 15-15-15, bentonite 0.5-1 parts, sterilization powder 10-
14 parts, it is micro- fertile 1-3 parts；Its preparation process is：Mud first is carried out into 35-42 DEG C of elevated-temperature seal to ferment 30-40 days, sterilization is added
Powder, sandy soil be sufficiently mixed it is uniform after, cover film is stacked 7-10 days, by biogas residue, the composite fertilizer that N-P-K content is 15-15-15,
Bentonite, micro- fertilizer are well mixed, obtain final product seedling medium.
Further, described sterilized powder is made up of following raw material：Realgar powder 5-8 parts, Chinese torreyanut powder 15 2-5 parts, bitter skin
10-12 parts of rattan powder, 5-7 parts of stem pith of the rice-paper plant powder.
Further, described micro- fertilizer is made up of following raw material：Potassium sulfate 2-6 parts, boric acid 8-10 parts, calcium nitrate 6-
10 parts, ammonium dihydrogen phosphate 2-4 parts, magnesium sulfate 2-4 parts.
Further, the nutrient solution described in step (4) is made up of the raw material of following weight portion：Heteroauxin 1-3 parts, cell
Mitogen 2-5 parts, salicylic acid 1-3 parts, white granulated sugar 3-7 parts, water 100-120 parts.
Further, removing for the seed rice described in step (5) broadcasts spacing for 10-15mm.
Further, when paddy rice is cultivated, the matrix in seedbed is cut into containing the 2-3 plants of substrate block of rice shoot, from pad paving
Stalk layer takes out, and is placed in paddy field, and the depth of water in paddy field does not exceed 1cm.
Beneficial effects of the present invention：The method of the present invention is simple and practical, it is easy to accomplish, workload is more saved than conventional method
When, labour is saved, vernalization rate is removed and broadcasts time saving up to more than 68%, and emergence rate is up to more than 95%, is emerged neat, after management, rice shoot
Healthy and strong growing way is good, and rice shoot is seasoned, directly cultivates rice shoot slow seedling soon, and the strong tap coefficient of tillering ability is high, resistance, cultivates paddy rice and saves
Kind, it is adapted to Anhui northern area and cultivates paddy rice.
