Description
Technical field
The present invention relates to a kind of method utilizing rice straw to prepare paddy rice slow-release fertilizer in strong sprout, belong to technical field of agricultural fertilizers.
Background technology
Stalk is the general name of ripe farm crop cauline leaf (fringe) part.Be often referred to wheat, paddy rice, corn, potato class, oil plant, cotton, sugarcane and other farm crop remainder after results seed.That one has multiduty reproducible Biological resources, people are exactly burn in a large number down on the farm to the most direct impression of stalk processing mode now, after the annual summer harvest, autumn harvest, in field, the flames lit up the sky, dense smoke shrouds, sometimes thick smoke almost makes people suffocate, and the situation that stop transport in the airport of causing due to crop straw burning, motorway is closed happens occasionally, and loss is difficult to counting.So stalk effectively can be treated as necessity.
In Rice Production, want to obtain high yield, except selecting properly kind except, nurturing staff is also the basis that paddy rice divides product, and current nurturing staff has several important technical links, and one is seed Seeds preprocess before nursery, and two is detain canopy ahead of time, raising ground temperature; Three is begin sowing in good time, and strong sprout is educated in light seeding; Four is alleviate disease to occur and timely supplementary fertilizer.These several sport technique segments, all linked with one another, there is problem in which link, all may cause the failure of whole seedling raising and strengthening.Thus on appropriate opportunity, fertilising is very important, also the appearance of some seedling strengthening nutrient agents is had at present, this seedling strengthening nutrient agent needed within the specific time, and how long interval applies fertilizer once, to ensure that paddy rice can absorb healthy and strong in absorption, simultaneously, although this seedling strengthening nutrient agent can play strong sprout, increase the effect of its output, improper fertilization, can rice lodging be caused, even occur burning seedling phenomenon.
Summary of the invention
The technical problem that the present invention mainly solves: need regularly fertilising for current seedling strengthening nutrient agent, and improper fertilization can cause rice lodging, even burn seedling phenomenon, provide a kind of method utilizing rice straw to prepare paddy rice slow-release fertilizer in strong sprout, the method takes full advantage of waste straw to make slow release fertilizer in strong sprout, can turn waste into wealth, make full use of its nutritive ingredient, this fertilizer only in the fertilising of seedling cultivation of rice phase once, without the need to repeatedly applying fertilizer, more need can not cause rice lodging and burning seedling simultaneously.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is, a kind of method utilizing rice straw to prepare paddy rice slow-release fertilizer in strong sprout, is characterized in that concrete preparation method:
(1) by rice straw uniform spreading on the ground, spraying stalk with water, make stalk water content be 89 ~ 92%, natural drying, when its water content is 62 ~ 73%, is the particle of 35 ~ 42mm with cutting machine by rice straw cut growth;
(2) above-mentioned obtained particle and chicken manure are carried out Homogeneous phase mixing according to mass ratio 4:1, again the layering of mixed straw particle is stacked, every layer thickness 8 ~ 12cm, often pile one deck to every layer of top water spray mixed enzyme agent, its fountain height is 5 ~ 10% of mixing water rice straw particle quality, heap stops stack layers after 8 ~ 10 layers, then covered with black plastic, be incubated, keep temperature to be 40 ~ 45 DEG C, once, ferment 45 ~ 50d in 2 ~ 4d turning;
(3) the mixing water rice straw particle after fermentation ends in step (2) being put into air dryer carries out air-dry, then puts it in pulverizer, is ground into 180 ~ 210 order powder;
(4) powder be ground into is put into coating machine and be preheated to 40 ~ 45 DEG C, add the urea-formaldehyde resin of mixing water rice straw powder quality 1 ~ 3% and the SPC-D of mixing water rice straw powder quality 0.6 ~ 1.2% more wherein, in encapsulation tool, turn to mixing water rice straw powder surface form bonding liquid layer;
(5) after rice straw powder surface to be mixed forms bonding liquid layer, be warming up to 48 ~ 52 DEG C, rotate until mould material wraps up mixing water rice straw powder uniformly, and film-forming;
(6) repeating step (4) and (5) are until mixing water rice straw powder is all wrapped up, and till film-forming, after terminating, are down to 28 ~ 35 DEG C.
In described step (2), the preparation method of mixed enzyme agent mixes by cellulase and the amount of quality than 1:9.
Application of the present invention: by the paddy rice slow-release fertilizer in strong sprout for preparing in the seedling cultivation of rice phase, be evenly sprinkled in farmland, every mu of 10 ~ 20kkg, after 2 ~ 3 months, finds that paddy rice grows up strong and sturdy, grows fine.
The invention has the beneficial effects as follows:
(1) stalk can be turned waste into wealth, make full use of its nutritive ingredient;
(2) fertilising is simple, only need apply fertilizer once, more can not cause rice lodging and burn seedling;
(3) operation steps is simple, and required cost is low.
