Description
Technical field
The present invention relates to a kind of agricultural crop straw precise forming extruder and prepare seedling medium straw using this extruder
The preparation method of plate, belongs to agricultural machinery technological field.
Background technology
China's agricultural crop straw annual production is 700,000,000 tons about, first of the row world.Agricultural crop straw is valuable renewable energy
Source, but for a long time due 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 the phenomenon that a large amount of straws are incinerated in year.
China seedling cultivation of rice is most of to adopt 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 in a large number year after year, and the past river bend, mountain region, sylvan life ground etc. are mainly to fetch earth source, has resulted in that great quantities of soil were washed away,
Vegetation is seriously damaged.Fetch earth now and be increasingly difficult to, peasant has to take dry land ground soil, big due to having year after year in dry land ground soil
The pesticide that amount is applied, with this seedlings and soil rice seedlings it occur frequently that poisoning, causes great economic loss to peasant household.As by digging drought
Calculating, the whole nation has nearly 120,000 mu of earth's surface topsoil soil to be scooped away to field topsoil depth 20cm every year.Nowadays the peace that nursery can use
Full soil is almost exhausted, is therefore badly in need of nursery replacement native (i.e. seedling medium) and meets the nursery demand such as Oryza sativa L..
Raw material processing rice nursery substrate based on straw, replaces soil with this substrate, realizes non-soil culture, not only can reduce
Soil losses, make full use of stalk resource, developing agricultural recycling economy, reduce the environmental pollution that crop straw burning brings and nursery takes
The problems such as soil destroys ecological vegetation, and utilize straw substrate nursery, rice shoot is better than at aspects such as plant height, radical, hundred plants of fresh weights
Conventional nutrient seedlings and soil, growth is neat, and root system disk is tied, and is easy to roll up 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 reduce, and can do sth. in advance nursery 3-5 days, can accomplish early rice transplanting, protect
Volume increase；Substrate seedling also has or not the advantages such as weeds source and pathogenic bacteria source be few compared with nutrition seedlings and soil.
In recent years, seedling cultivation of rice develops towards scale, batch production direction.Therefore, make Oryza sativa L. using stalk material
Deng seedling medium, need the size shape solving 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 be applied to the standard size 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, realize 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 utilize and increasing
The best way received.
