Description
Technical field
The present invention relates to a kind of agricultural crop straw precise forming extruder and utilize this extruder to prepare seedling medium straw
The preparation method of plate, belongs to agricultural machinery technological field.
Background technology
China's agricultural crop straw annual production is about 700,000,000 tons, first of the row world.Agricultural crop straw is valuable renewable energy
Source, but for a long time owing to there is no economy, efficient utilization ways, there is more than 60% straw to be burned in the ground by peasant household every year
Fall, severe contamination environment.Make the technological approaches such as straw coal and feedstuff and there is also the application bottleneck such as cost and technique, so often
Still there is the phenomenon that a large amount of straw is incinerated in year.
China's seedling cultivation of rice major part uses rice seedling on upland field operating type, and nursery effect is good, promotes more than 30 year in China.But
Nursery needs to fetch earth the most in a large number, the past river bend, mountain region, sylvan life etc. be seedbed of mainly fetching earth, have resulted in that great quantities of soil were washed away,
Vegetation is seriously damaged.Fetching earth now and be increasingly difficult to, peasant has to take dry land ground soil, the biggest owing to having in dry land ground soil
The pesticide that amount is used, with this seedlings and soil rice seedlings it occur frequently that poisoning, causes great economic loss to peasant household.As by digging drought
Topsoil deep 20cm in field calculates, and the whole nation has the earth's surface topsoil soil of nearly 120,000 mu to be scooped away every year.Nowadays the peace that nursery is desirable
Full soil is close to exhaustion, is therefore badly in need of nursery replacement soil (i.e. seedling medium) and meets the nursery demands such as Oryza sativa L..
Process rice nursery substrate with straw for main material, replace soil by this substrate, it is achieved non-soil culture, not only can reduce
Soil losses, make full use of stalk resource, developing agricultural recycling economy, and environmental pollution and nursery that minimizing crop straw burning brings take
Soil destroys the problems such as ecological vegetation, and utilizes straw substrate nursery, and rice shoot is better than at aspects such as plant height, radical, hundred strain fresh weights
Conventional nutrient seedlings and soil, growth is neat, and root system dish is tied, it is simple to volume seedling transport, is suitable for mechanical work rice transplanting；Average bed temperature ratio
Conventional nutrient seedlings and soil quick heating, water conservation, insulation, irrigation times reduces, can do sth. in advance nursery 3-5 days, can accomplish early rice transplanting, protects
Volume increase；Substrate seedling compared with Nutrition Soil nursery also with or without advantages such as weeds source and pathogenic bacteria source are few.
In recent years, seedling cultivation of rice develops towards scale, batch production direction.Therefore, stalk material is utilized to make Oryza sativa L.
Deng seedling medium, need the size shape solving that loose powder of straw is fabricated to standard criterion, and through follow-up seeding and growing seedling and
Have additional nutrients additive and moisture is allowed to the standard size that is applicable to used by rice transplanter.A kind of continuous high pressure compressed of straw is needed to set
Standby, make straw seedling medium stalk board.Ensure that raw material is sustainable, it is achieved matrix substrate compression standard, and greatly reduce
Nursery work flow, improving productivity more than 70%.The new way that this technology exploration stalk material utilizes, have developed reality
The agricultural machinery of this technology existing, has preferable economic benefit and social benefit, is that current stalks utilizes and increases
The best way received.
