Description
【Technical field】
The present invention relates to Rice Cropping technical field, and in particular to a kind of paddy drought seedling seedling-growing method.
【Background technology】
Rice planting technology is the main direction of development of China's modern times rice technology, to country labor force transfer and aging bar
Stable grain-production, improves rice yield under part, promotes rice large-scale production, raises labour productivity significant.
With socio-economic development, country labor force transfer and aging, under policy support, China's rice planting technology is quickly grown.
China's rice mechanical transplanting seedling at present mainly has dry rice seedling and moistening watery ricenursery method, and dry rice seedling method is generally used for seedling in greenhouse
Environment, but either dry rice seedling still moistens watery ricenursery method, and seedling-cultivation plate is essential condition, but uses now
Seedling-cultivation plate be all plastic rice seedling-raising disk, this seedling-cultivation plate must be changed a collection of using several years, this not only adds cost, and be scrapped
Seedling-cultivation plate pollution is caused to environment.
【The content of the invention】
It is an object of the invention to：In view of the above-mentioned problems, providing a kind of paddy drought seedling seedling-growing method, solving Dry Breeding Seedlings must
Seedling-cultivation plate must be used, cause to increase the problem of cost pollutes environment with the seedling-cultivation plate scrapped.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of paddy drought seedling seedling-growing method, comprises the following steps：
(1) rice seedling bed selection and seedbed preparation：Land leveling, the convenient nonirrigated farmland of irrigation and drainage are selected as dry rice seedling field, by 1~
1.4m width does seedbed, and seedbed surrounding is fenced up with plank, and plank upper surface is higher than seedbed bed surface, and in seedbed, bed surface covers last layer
Wet soft clay, clay is scraped smooth, and clay thickness is 5-9cm, is dried 1-2 days, until clay is tack-free, then is had with sprout-tray model
Surface of clay stamp with seedling disk inner surface one to seedling disk line, and leaking hole is opened up in argillic horizon, then uses transparent membrane
Rain-proof shelter is built, clay is dried 25-30 days so that clay is dried to sun-dried mud brick；
(2) matrix prepares：The soil in earthworm pond is taken, dry doubling is dried and crushes to obtain matrix soil, then take by volume
Matrix soil 50%, organic fertilizer 20%, rotted leaf 25% and peanut cake 5% are well mixed, using acid adjustment material by substrate pH
5.0~5.5 are adjusted to, one layer of 5-10mm charcoal powder is then spread in sun-dried mud brick, then the matrix prepared is laid on charcoal powder, base
3~5cm of matter laying depth；
(3) presoaking and germinating：Seed rice is positioned in bactericidal liquid and soaked 10 hours, then takes out to be put into clear water and soaks 40h,
Then the vernalization under conditions of temperature is 28~35 DEG C, humidity is 85%, the rice tooth that seed rice grows 2-3mm stop vernalization；
(4) sow：Sowing goes to matrix to spray clear water so that soil humidity reaches more than 95%, then will urge bud
Seed rice is equably broadcast in matrix, vernalization 150~200g of seed rice is sowed per square meter according to variety type and the length of time rice seedlings grow long short-press, then use
Matrix covers seed rice, and cladding thickness is about 2~4mm.
(5) rice shoot management：After planting, 2 water are sprayed to rice shoot daily, morning, once the dusk was once so that soil humidity
It is maintained between 70%-95%, forbids having ponding in matrix, and carry out protection against rodents insect prevention prophylactic measures, sows 12 days, pressed to rice shoot
100L/ mus spray inorganic solution once, to promote seedling growth.
Further, the clay is is taken at rice field 5-15cm depths, and silt content is less than 20% weak soil, and clay takes out
Afterwards plus water stirs into muddy.
Further, the preparation method of the sprout-tray model tool is：A seedling disk is taken, moulding mud is filled into seedling disk and is pressed
It is real, then moulding mud is dried, separate seedling disk and moulding mud, you can obtain sprout-tray model tool.
Further, the bactericidal liquid is put in pure water and is stirred using toothpaste and garlic juice, is then filtrated to get,
Toothpaste, garlic juice and pure water are 2 in mass ratio:10：11, toothpaste and garlic have good bactericidal effect, and to seed rice
Fanout free region.
Further, inorganic solution is dissolved in 500 parts of water by 2 parts of 10 parts of nitrogenous fertilizer, 5 parts of phosphate fertilizer and potash fertilizer in mass ratio
It is made.
Further, when taking the soil in earthworm pond, first the earthworm in soil is removed.
Further, the rotted leaf is the natural degradation olive leaf of more than 1 year, and driffractive ring alkene ether is mainly contained in olive leaf
The composition such as terpene and its glycosides, flavones and its glycosides, biflavone and its glycosides, low molecule tannin, to communicable and pernicious micro- life
Thing has full effect, and it can stop the invasion of fungi, yeast and mold, and the preventing and treating to rice disease has effect well
Fruit.
Further, dried to accelerate the clay of printed seedling disk line, accelerate the air stream of surface of clay using blowing device
It is dynamic.
By adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, the present invention uses covers the wet soft clay of last layer in seedbed bed surface, and is stamped and seedling disk inner surface in surface of clay
One to seedling disk line, finally clay is dried into sun-dried mud brick, sun-dried mud brick is gathered materials on the spot, supplied materials is convenient, makes letter equivalent to seedling-cultivation plate
It is single, cost free, after shoot transplanting equipment, rain-proof shelter need to only be removed, sun-dried mud brick will natural decomposition through exposing to the sun and rain after a while
For can long-term cropping soil, without recovery, and safety non-pollution.
2nd, the present invention uses matrix of the soil as seedling in earthworm pond, and the soil in earthworm pond contains substantial amounts of earthworm
Detection of the unit such as excrement, Minister Agriculture of China's fertilizer Product Quality Verification Centers to wormcast, wormcast Nitrogen-and Phosphorus-containing potassium is respectively 1.4%,
1%th, 1%, containing humic acid 46%, containing 23 kinds of amino acid, abundant earthworm fibrinlytic enzyme, every gram of wormcast has 105 × 8 beneficial to micro-
Biology (aging soil only have 105-106), and have particle uniformly, ventilative water conservation, tasteless health, the features such as fertilizer efficiency is lasting, contain
The wormcast of water 85% shines 15 days in heat, and 20 centimetres of depths water content greatly enhance the drought-resistant ability of soil still up to 45%,
Earthworm enzyme in wormcast can also kill virus, harmful bacteria and the material for having inhibitory action to plant growth in soil, adopt
By the use of the soil in earthworm pond as the matrix of seedling, the healthy growth of rice shoot can be accelerated, strengthen drought resisting and the disease resistance of rice shoot
Ability.
3rd, one layer of charcoal powder is provided between argillic horizon and hypothallus, charcoal powder can absorb moisture and store, in hypothallus
When moisture declines, charcoal powder by the water release of storage, can keep the moisture of hypothallus, and charcoal powder is more
It is lax, facilitate shoot transplanting equipment.
