(3) sowing: first matrix is filled to seedling-cultivating tray, with mist method, water permeable, then by the seed through seed soaking evenly sowing in seedling-cultivating tray, at the surface of the seed covering fine earth;
(4) the indoor vernalization of banking up: seedling-cultivating tray is after planting displaced to indoor, stacks into germination heap and concentrate vernalization, wrap up tightly with the plastic film heap that will germinate, allow temperature in the shed rising;
(5), while having 80% to emerge in seedling-cultivating tray, carry out the outdoor rice seedling bed of dislocation and grow seedlings.
Described matrix is mixed according to 1: 1 ratio after sieving with land for growing field crops original soil 20 orders after fresh wormcast 20 orders are sieved in preparing.Wormcast proportion control is in 60%.
In described sowing, at the surface of the seed, cover the thick fine earth of 0.5cm.
Described indoor banking up in vernalization, stacks into the high germination of 1-1.5m heap, allows in plastic film temperature is disposable is raised to 25 ℃.
The present invention can realize transplanting seedling quality healthy and strong, easily plant the target that performance is good, rice shoot regularity is high, seed rice availability is high.The rice shoot that adopts this method to cultivate has that seedling is strong, good, the white root of root system development accounts for more than 90%, improving activity of root system is strong; Utilization is soaked seed, and not vernalization is sowed and the indoor germination accelerating method of banking up of concentrating, and has advantages of that seed availability raising 10%, rice shoot regularity raising 15%, emergence rate improve 10%.The rice shoot that adopts this method to cultivate, can increase production 10% left and right.Transplanting seedling quality, rice shoot regularity, easily cultivation property and seed availability problem have been solved.Utilize wormcast as culture medium there is rice shoot stalwartness, Bai Genduo, packing band soil nature can be good, be easy to that machine is planted and survival, seedling growth is sane, output is high feature; By soak seed not vernalization floppy disk after planting indoor banking up concentrate the method for vernalization, rice shoot regularity is high, growth high conformity, seed rice availability are high.
Embodiment
Technical thought of the present invention:
After selecting fresh wormcast 20 orders to sieve with land for growing field crops original soil 20 orders sieve soil according to 1: 1 ratio, mix as transplanting culture medium, matrix is passed through to the traditional thread binding seedling-cultivation plate of machine flowing water or people's tool disk, again the seed rice through seed soaking 48h is carried out to machine sowing or artificial evenly sowing, cover through the 20 orders fine earth 0.5cm that sieves thick, then seedling-cultivating tray after planting being moved on to indoor heap, to be set to 1-1.5m high, after cover film is tight, concentrate vernalization, after bud in seedling-cultivating tray more than 80% is unearthed, seedling dish is transplanted in outdoor rice seedling bed and is grown, until three leaves wholeheartedly.
Main method and the step implemented:
Matrix is prepared, and---grow seedlings in rice seedling bed in sowing---vernalization of banking up---
Matrix is prepared:
Get fresh wormcast and fully mix as transplanting seedling cultivation matrix according to 1: 1 ratio with the land for growing field crops 20 orders original soil that sieves after 20 orders sieve, according to seedling-cultivating tray type and size, determine matrix preparation amount.Because wormcast has required available nutrient during seedling cultivation of rice, and granular structure and water conservation, to hold fertile ability strong, and the original soil that admixture is certain, can meet transplanting to rice shoot solid root ability, shatter value and requirement separatory.
Paddy rice is basked seeds and soaks seed:
Before seed soaking, 1-2d, by rice paddy seed through the sun 1-2d that is exposed to the sun, promotes seed vitality, kills the surface of the seed bacterium; Then seed is immersed in to 48h in clear water alive, can adds the seed soaking of suitable medicament according to seed characteristics, before sowing, 2h picks up seed, with clear water rinse well, airing waits to broadcast.
