Description
Technical field
The present invention relates to field of rice cultivation, more particularly to a kind of method of raising seedling of rice.
Background technology
Rice is one of main cereal crops in the world, and the nearly half population in the whole world is using rice as staple food.China is rice
Big country is planted, cultivated area maintains essentially in hundred million mu or so of 4.2-4.5.Existing seedling-cultivation technique seedling quality is poor, and emergence rate is low,
Seedling stage is susceptible to pest and disease damage, and cost is higher, can not carry out large-scale promotion application.
Invention content
The purpose of the present invention is to provide a kind of method of raising seedling of rice, and planting percent can be improved, and reduce seedling stage diseases and pests, change
Kind seedling quality, reduces seedling cost.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of method of raising seedling of rice, which is characterized in that include the following steps：
(1) Nutrition Soil prepares：Select vegetable garden soil, dry land soil, paddy soils or the silt soil of curing carry out hack, sieving as
Nutrition Soil base-material, then by weight by 500-800 parts of base-material, 50-100 parts of stalk fermentation object, 5-10 parts of chitin, wheat meal
The uniformly mixing of 20-30 parts of stone, 20-35 parts of humic acid, 1-2 parts of propiconazole, 3-5 parts of urea, forms the Nutrition Soil that pH value is 5-6；
(2) seed preparation：The kind that selection is suitble to local the high-quality of plantation, high yield, resistance strong；By seed through seed selection,
It basks seeds, de- awns, Medicament soaked seed, cleaning, vernalization, sow after dressing seed processing, the bud length of planting with sowing machine is no more than 2.5mm；
(3) seedbed preparation：Selection irrigation and drainage are convenient, do rice seedling bed convenient for the field of management, set up steelframe seedling greenhouse, seedbed
Specification is the wide 200cm of furrow face, seedling furrow width 50cm, depth 15cm, surrounding furrow width 30cm, depth 25cm；
(4) it sows：Using floppy disk or hard disk seedling, 25-35 per acre；Nutrition Soil, soil layer are laid on floppy disk or hard disk
Thick 1.5cm, surfacing, and sowed after so that Nutrition Soil moisture is reached saturation state；The earthing, thickness of earth covering is after planting wanted to be
0.3-0.5cm；
(5) seedling management：Vertical seedling stage heat and moisture preserving, temperature are 25 DEG C, relative humidity 80%；When rice shoot is unearthed 2cm
Take off film hardening；When daily mean temperature is less than 12 DEG C, film should not be taken off；Greenhouse rice nursery hardening temperature is controlled at 20-25 DEG C, evening daytime
Epiphragma seedling-protection when above less than 12 DEG C；Water management pay attention to it is first wet after it is dry, before rice shoot tri-leaf period, Nutrition Soil moistening is kept not to send out
In vain, it imposes wean fertilizer in time according to the growth of cereal crop seedlings and send and transfer fertilizer；
(6) rice shoot standard：Rice shoot reaches 3 leaf, 1 heart, height of seedling 12-15cm, and stem foot is wide to be less than 2mm, radical 12-15 items/seedling,
Transplantation of seedlings can be played.
Further, Nutrition Soil is composed of the following components by weight：600 parts of base-material, 90 parts of stalk fermentation object, first
6 parts of shell element, 28 parts of medical stone, 32 parts of humic acid, 1.2 parts of propiconazole, 4 parts of urea.
Beneficial effects of the present invention：Propiconazole, humic acid are mixed with chitin and can be opposed by the present invention in specific proportions
There is the germ of blight and rice blast apparent inhibition, Nutrition Soil to contain various the same needed for rice seedling growing
Element, can effectively facilitate the development of rice shoot, improve seedling quality, stalk fermentation object biomass resource seedling medium packing is poor,
The problem that slow seedling is slow, survival rate is not high.
