Abstract

The present invention discloses sweet potato organic special-purpose fertilizer and provides a sweet potato organic special-purpose fertilizer with a simple production method, low cost and lasting fertilizer effect, which can improve the quality of sweet potatoes. The technical scheme of the present invention has the essential points that after wetted and macerated with clear water, plant ash and fragmentary soybeans, bean dregs, bean cakes and attapulgite powder are jointly stirred, wherein the fragmentary soybeans, the bean dregs, the bean cakes and the attapulgite powder are steamed and naturally fermented; through a double-roll extruder, the constituents are extruded into pieces; the pieces are conveyed to a concrete court to be dried; then, the pieces are crushed by a feed grinder and are granulated by a granulating disc; the granules enter a rotary drum dryer to be dried; after dried, the granules can be packaged into a finished product.

Description

Sweet potato organic fertilizer and production method thereof

Technical field

The present invention relates to a kind of fertilizer, be specifically related to a kind of sweet potato organic fertilizer and production method thereof.

Background technology

Sweet potato has another name called sweet potato, and the north is called sweet potato, pachyrhizus.Sweet potato is nutritious, contains protein, fat, carbohydrate, calcium, phosphorus, iron, materials such as carotene and vitamin A, B, C; Yam loaf root meat color is various, generally is divided into red heart kind and white heart kind.Shade and nutritive value are closely related.Street corner, many cities and towns, the whole nation all has the baking sweet potato to peddle the popular dessert that has become old children all to like.

Sweet potato is long vegetative period, and the fertile amount of consumption is big, and peasant household is in order to pursue high yield, and often excess is executed some chemical fertilizer partially, and its nutrient can not effectively be absorbed by sweet potato, and nitrogen, phosphorus, potassium form salt accumulation easily by soil fixing, cause soil acidification; Soil nutrient structure imbalance, the physical behavior variation easily makes the yam loaf root in nutritional trouble in vegetative period, part transforms biosynthesis block in the body, causes the sweet potato quality to reduce, in addition soil compaction, influence expanding of yam loaf root, can not obtain very high output, increased cost on the contrary.

Use human excrement, feces of livestock and poultry and common farm manure merely, the interior quality of sweet potato increases, but the piece root appearance of sweet potato is rough spot is arranged, and causes visual appearance relatively poor.Inferior sweet potato dull sale, price is also on the low side, directly the economic benefit at influence plantation family.

Because the sweet potato inferior quality, the people that many love are eaten sweet potato says that present sweet potato is not very good eating.Therefore, guaranteeing further to improve output and economic benefit under the high-quality prerequisite of sweet potato, is that current sweet potato produces important topic upward anxious to be solved.

Existing patent disclosure the production technology of many fertilizers, for bigger contribution has been made in agriculture production, but be used for the organic fertilizer of sweet potato, at home and abroad not seeing as yet has report.

Summary of the invention

The objective of the invention is to overcome weak point in the prior art, provide that a kind of production method is simple, with low cost, fertilizer efficiency is lasting and can improves the sweet potato organic fertilizer and the production method thereof of sweet potato quality.

The present invention is achieved by following technical proposals: plant ash is imported in the cement pit, and it is moistening in addition to spray an amount of clear water, and the water content of plant ash is controlled at 5～20%, and deposits 10～40 days; With broken soya bean 25～45 weight %; bean dregs 30～50 weight % and soya-bean cake 10～30 weight % carry out boiling; can pinch into the ooze shape after well-done for well; and import and carry out spontaneous fermentation in another cement pit; leavening temperature is controlled at 20～40 ℃; water content is controlled at 10～15%; fermentation time is 4～7 days: get plant ash 30～45 weight % that handled then respectively; ripe broken soya bean by fermentation; bean dregs and soya-bean cake mixture 45～60 weight % and attapulgite 10～15 weight % stir jointly; through the pair roller forcing machine; be squeezed into sheet; and be transported to airing on the cement field; when water content≤8%; common input feed grinder is pulverized; granulation is carried out with granulating disc in smashing fineness≤0.1 millimeter, and granularity is controlled at 1～4 millimeter; and be transported in the rotary drum dryer and dry; temperature is controlled at 100～150 ℃, and water content≤2% can be packaged as finished product after the oven dry.

Sweet potato organic fertilizer of the present invention, after peasant household uses, it can increase the content of the soil organism, make soil full of vitality, help improving the growth of yam loaf root, and can keep the fertility of soil and strengthen the water-holding capacity of soil, guarantee that the sweet potato quality significantly improves, and output and economic benefit all there are tangible increase.

Embodiment

The invention will be further described below in conjunction with embodiment.

1, plant ash is the product after agricultural crop straw, rice husk, wood sawdust, faggot, the dry branches and fallen leaves burning, its source is very extensive, purchasing price is cheap, and plant ash contains the various nutrient elements of sweet potato needs, as phosphorus, potassium, calcium, magnesium, sulphur and boron, manganese, zinc, molybdenum, copper etc.Serve as maximum wherein with potassium, calcium contents, the plain major part of wherein contained potassium is water-soluble, be a kind of quick-acting potash fertilizer, also being potash fertilizer resource best in the fertilizer, simultaneously also is that chemical fertilizer institute can not replace, plant ash be particularly useful for acid on earth, but, plant ash can not air storage, can not expose to the sun and rain, otherwise potassium element seepage or lose with current and to reduce fertilizer efficiency thereupon.Plant ash can be imported in the cement pit, it is in addition moistening to spray an amount of clear water, and the water content of plant ash is controlled at 15%, and deposits the system of macerating in 20 days, to reduce its alkalescence and to increase fertilizer efficiency.

2, broken soya bean, bean dregs and soya-bean cake are the byproducts of making bean food or oil expression, cheap, it contains the various nutrient elements of sweet potato needs equally, serve as maximum wherein with nitrogen, phosphorus content, organic content is very high, but not directly as fertilizer sources is used, need by fermentation after, just can make full use of their effective nutrition.Get broken soya bean 35 weight %, bean dregs 40 weight % and soya-bean cake 25 weight % etc. aborning and carry out boiling, pinching into the ooze shape after well-done for well, and import and carry out spontaneous fermentation in another cement pit, leavening temperature is controlled at 40 ℃, water content is controlled at 15%, and fermentation time is 7 days.

3, after the acidic fertilizier that ferments owing to plant ash and broken soya bean, bean dregs and soya-bean cake mixes, can help to decompose its oil, further improve its fertilizer efficiency, therefore getting the plant ash 35 weight %, ripe broken soya bean by fermentation, soya-bean cake, bean dregs mixture 55 weight % and the attapulgite 10 weight % that handled respectively stirs jointly, attapulgite not only plays cohesive action, and can absorb the moisture of above-mentioned mixed together thing, and contain the several mineral materials nutritive element of multiple sweet potato needs, through the pair roller forcing machine, be squeezed into sheet, and be transported to airing on the cement field.

4, when flaky mixture water content≤8%, import feed grinder jointly and pulverized, smashing fineness≤0.1 millimeter.

5, the mixture after pulverizing, be transported to and carry out granulation on the granulating disc, granularity is controlled at 1～4 millimeter, is transported in the rotary drum dryer then and dries, and temperature is controlled at 100～150 ℃, and water content≤2% can be packaged as finished product behind the dryer.
