Description
Technical field
The present invention relates to rice cultivating technique field, specially a kind of machine-transplanted rice using liquid manure vector construction seedling bed without
Plate seedling raising method.
Background technology
In recent years, with the rapid development of economy, the of the right age labour's in rural area significantly goes out, rural area production is directly resulted in
The decline of power, labor cost rise therewith.Therefore, Rice Production is badly in need of the agriculture production technology of Imported Modernized and profession is set
It applies, mechanization has become the important selection for modern Rice Production.Most weak link is machine in Rice Production entire mechanization
Tool rice transplanting technology,
And seedling is the first step of transplanting.The seedling-cultivation technique of standardization is the key that realize rice planting technology, moulds disk（Floppy disk or
Person's hard disk）Seedling and double film seedling become two kinds of relatively common at present machine transplanting of rice seedling raising methods because its is easy to operate, feasibility is good.
But there is also some practical problems, mould disk（Floppy disk or hard disk）Artificial balance is needed before seedling planting, being needed after the machine transplanting of rice will be special
It is recycled and is cleaned with seedling bed, need the storage place of special seedling bed.In addition, special seedling bed one is only with 1-2 times, utilization rate is low,
It is of high cost.Compared with moulding plate seedling raising, the cost of double film seedling material requesteds early period and investment is less, but in actual mechanical process
In, double film seedling need seedling with soil cutting into rectangular seedling block, can be put into the seedling support of rice transplanter, such to cut
Cut has serious damage to rice shoot, and whole process expends time and labor very much.
The carrier of China's matrix seedling mainly has dry fine earth and mud, commodity matrix, stalk powder etc..Dry fine earth and mud
Bed soil for raising seedlings equally as rice, is to be distinguished according to the difference of its water content, therefore there has been dry fine earth seedling
With the two different seedling raising manners of mud seedling, the rice shoot rice root that dry fine earth and mud method of raising seedling are educated is merged with soil
Preferably, it turns green behind rice shoot machine transplanting of rice crop field fast, seedling effect is good, but mud seedling needs artificial or machine to make mud dress in rice field
Disk, and the sundries such as the standing grain root and stem of certain plants, the weeds left after stone, rice harvesting are removed when mud making, remove the labor intensity of work
Greatly, labour costs is high.And dry fine earth seedling, take paddy field plow layer soil before needing the winter, crush soil after drying, weed out stone,
Weeds mix fertilizer storage, entirely fetch earth, dry, crushing, sieve that soil, to mix the process such as fertilizer more, labour costs height needs simultaneously
Special storage place.In addition, the seedling block humidity that dry fine earth and mud are bred as is difficult control, the rainy day is such as encountered before the machine transplanting of rice, then
Seedling block is easily rotten, and such as high temperature, then seedling block is fugitive, and fortune seedling difficulty increases, and field hole rate increases after plant.Commodity in use matrix is educated
Seedling is then light compared with mud and dry fine earth method, can carry out pipelining in seedling factory, operation is easier, but seedling raising ground substance
Materials cost it is higher.In addition, comprising chemical substances such as fertilizer, pesticides in matrix when matrix seedling, the management to humidity of seedbed
It is required that stringent, excess moisture or it is very few be easy to cause dead seedling, and suitable moisture is how many is changed by temperature height
It influences, often because grasping bad normal generation rotten and dead seedlings in seedling.Stalk powder overcomes the high disadvantage of commodity matrix seedling cost,
But it with fertilizer, adjusts acid and prevention and control of plant diseases, pest control difficulty larger, be easy to cause and hinder seedling seedling rot.
Either mould disk（Floppy disk or hard disk）Seedling or double films without plate seedling raising, regardless of be with matrix or mud,
Above-mentioned all method of raising seedling are both needed to strict control moisture and fertilizer in entire seedling process, take time and effort, but also there is
Because mismanagement rice shoot is emerged the risk of irregular, dead seedling etc..Therefore, design is a kind of can automatically provide liquid manure, and not need seedling
The method of raising seedling of bed saves labour for Rice Production, reduces cost and be of great significance.
Invention content invents a kind of base the purpose of the present invention is the deficiency for above-mentioned existing machine-transplanted rice seedling raising method
In water-fertilizer integral without seedling bed place seedling new method, carrier of the method for raising seedling using water-keeping material as liquid manure is rice shoot
Throughout the growing season offer fertilizer and moisture, chemical fertilizer may be implemented and water resource persistently provides.It is suitable with homemade quality simultaneously
In, short texture, good permeability without fertilizer ground substance be seedbed.The small seedling compartment of required size is separated out in seedbed with plastic strip.Tool
