Description
Technical field
The invention belongs to technical field of agricultural breeding, and in particular to a kind of bed seedling method for culturing seedlings of early rice.
Background technology
China Rice Cropping distributed area is based on south, and Rice Production is increasingly concentrated to dominant area, in recent years China
Rice Production is progressively concentrated to the middle and lower reach of Yangtze River and Heilungkiang rice producing region, and South Rice Region of China accounts for China's rice growing area at present
94%, Yangtze river basin rice area accounted for the whole nation 65.7%, wherein early rice is in 13 provinces（Area）Production, sown area are larger.
But because seedtime temperature is difficult to hold, if miscarriage, it will usually cause the rotten bud of rotten kind, therefore cultivating at present more
Preceding carry out nursery, so as to improve the survival rate of early rice, but because farming season is difficult to hold, early rice has focused on water during seedling management
The height growth of rice, but its inferior quality, cauline leaf dry is less, and the rice mouthfeel planted out is poor, for industrial grain or storage
Standby grain, if can not be utilized in time, can usually cause to waste, plantation industry is lost more than gain, it is therefore desirable to which one kind can
Improve the method for culturing seedlings of early rice quality.
In current method for culturing seedlings, common issue is that, ratio is improper in composite fertilizer, and in early rice maturation, temperature is too high,
If nitrogenous fertilizer usage amount is high in nursery, planting percent can be reduced, so as to cause gained seedling inferior quality.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of bed seedling method for culturing seedlings of early rice.
The present invention is achieved by the following technical solutions：A kind of seedbed method for culturing seedlings of early rice, comprises the following steps：
（1）Matrix, which is matched somebody with somebody, to be taken：40 parts of stalks to ferment, 25 parts of horsehits to ferment, 5 parts of marine algas fermented are taken, with 20
Part vermiculite and 8 parts are used as the remaining residue of culture medium of edible fungus, add 0.2 part of composite fertilizer, 0.6 part of NMF, 0.4 part of adhesive
And 0.8 part of strengthening agent is puddled uniformly；
The remaining residue of culture medium of edible fungus is added in matrix, in the case where effectively utilizing useless resource, moreover it is possible to reduce
The usage amount of azophoska, in addition, the content of nitrogen in composite fertilizer is added in strict control, avoid nitrogen content in rice shoot too high, in height
The lower disease resistance of temperature weakens.
（2）Presoaking and germinating：The seed rice of full seed is selected, under conditions of 65-75 DEG C, is irradiated with 800-1000lx illumination
3-4 hours, it is then placed in 40-50 DEG C of warm water and soaks 12 hours, a water was changed every 4 hours；The seed soaked is put
Enter seed soaking 8-10 hours in 400 times of strong chlorine oil decoction, then rinse 15-20 minutes with water；The vernalization in the cloth bag of humidity, use
Warm water controls its temperature at 35-40 DEG C, and after showing money or valuables one carries unintentionally, control temperature is at 25-30 DEG C, until bud grows half paddy, in normal temperature
In open a bag hardening；
With strong light processing seed before seed soaking, the germination percentage and germinating energy of seed can be effectively improved, is not susceptible to simultaneously
Ambient weather influences.
（3）Sowing：After vernalization and seed is uniformly sprinkling upon above the matrix in seedbed, with 0.6kg/ ㎡ dry planting rice seed
Kind, then cover seed, the incineration residue of Chinese medicine and the mixed proportion of matrix with the incineration residue of Chinese medicine and the mixture of matrix
For 3:1, lid kind thickness is 0.5-1cm, squirts lid kind layer with acid Aqua Folium Camelliae sinensis after lid kind, then uses non-textile mulch；
Puddled with bed seedling matrix with the incineration residue of Chinese medicine in lid kind layer choosing, now for discarded Chinese medicine, can be used for
Heating is burned, amount of heat can be produced and do not polluted the environment, then lid kind layer is squirted with acid Aqua Folium Camelliae sinensis, can effectively control
Infection process processed.
（4）Seedbed management：
A. moisture management：Watering in good time, control seedbed moisture content are maintained at 40-50%；It is filled with enough when rice shoot grows to 11 heart of leaf
Water, seedbed moisture content is kept in 65-75%；
B. temperature treatment：After planting to before the heart stage of 1 leaf 1, it is 28-30 DEG C to keep day temperature, and evening temperature is 18-22
℃；Before the heart of 1 leaf 1 to the heart stage of 2 leaf 1, it is 25-28 DEG C to keep day temperature, and evening temperature is 15-18 DEG C；After the heart of 2 leaf 1, protect
Day temperature is held as 22-25 DEG C, evening temperature is 15-18 DEG C；
C. top dressing management：A rich water was poured every 10 days after taking off film, each dose is 18-25g/ ㎡, using nitrogen in fertilizer
Content is no less than 8%, and phosphorus content is no less than 4%, and potassium content is no less than 1.5%, and Zn content is no less than 0.3%；
（5）Play seedling：Transplanted when rice shoot grows to 31 heart of leaf.
As further improvement of these options, urea, ammonium chloride, ammonium sulfate, phosphoric acid one are included in the composite fertilizer
Ammonium and potassium chloride, urea, ammonium chloride, ammonium sulfate, the mixing ratio of MAP and potassium chloride are 1:1.5:0.8:1.8:1.2.
As further improvement of these options, step（3）Described in Chinese medicine be honeysuckle, the capsule of weeping forsythia, Radix Codonopsis, dried orange peel,
Two or more any mixture in hawthorn.
As further improvement of these options, after the acid Aqua Folium Camelliae sinensis infuse 1-2 hours for tealeaf residue boiling water,
It is 2-3 to be adjusted Aqua Folium Camelliae sinensis to pH value with acid solution.
The present invention has advantages below compared with prior art：
The stalk to ferment, horsehit and marine alga are employed in the present invention in matrix, with the use of as edible fungus culturing
Expect remaining residue etc., containing abundant organic matter and humic acid, and contain abundant trace element, there is stronger anti-microbial property,
Reduce the use of insecticide, green, rice shoot can reach transplanting standard in 25 days；
Contain certain mineral matter in the incineration residue of burned Chinese medicine, mixed in proportion with seedling medium, institute's structure
Into lid kind layer can effectively be incubated, moistening effect is good, is sprayed with acid Aqua Folium Camelliae sinensis, can not only make contained organic matter in tealeaf residue
It is fully used with trace element, moreover it is possible to play the pest-resistant effect of antibacterial；
During seedling medium and rich water quality management, replaced by raw material and change management method and reduce applying for rich water
With, reduction seedling cost, while reduce certain labor intensity；
After planting coordinating the management of liquid manure and temperature in the present invention, seedling root growing way can be made preferable, easily formed
Continuous seedling piece, be advantageous to transplanting operation, slow seedling is fast after transplanting, and seedling quality is good, and pest-resistant resistance against diseases is strong.
