Description

Organic-inorganic composite fertilizer

The present invention relates to a kind of organic and inorganic and mix fertilizer, particularly a kind of waste crop materials, poor pool and inorganic fertilizer and the micro-composite fertilizer that forms.

Existing market is sold and mostly the composite fertilizer of use is the inorganic composite fertilizer that inorganic fertilizer and trace element are formed, though this fertilizer can satisfy the needs of plant-growth at short notice, but can not satisfy long plant needs in vegetative period, and use inorganic fertilizer for a long time and can cause soil compaction, it is bad that soil property becomes.And simple application of organic fertilizers, plant absorbing are slow, are difficult for reaching balance between various effective ingredients, cause fertilizer efficiency low.People study organic-inorganic composite fertilizer in recent years, as Chinese patent 89101451.9 introduced with add a certain amount of nitrogen, phosphorus after human excrement, the brid guano mixed fermentation, that potassium is made composite fertilizer's application effect is better, but its raw material is collected, the transportation difficulty, complex manufacturing, facility investment is big, and necessary composition is incomplete.The technology for making high-efficiency comprehensive compound fertilizer of Chinese patent 90104584.5 introductions though the interpolation inorganic fertilizer can satisfy the plant weak point, supply fertile needs for a long time with the micro-compound fertilizer of forming after utilizing the municipal wastes fermentation, is turned waste into wealth; But can not remove plant-growth and the deleterious material of human and livestock health in the raw material, organic content difference in different cities and different areas, same city or the different time rubbish is very big, quality product is difficult to unanimity, add this compound fertilizer production technology complexity, the water absorbing and retaining properties of product own is poor, and only is suitable for city production.

The objective of the invention is to overcome above-mentioned deficiency, provide a kind of raw material sources wide, production technique is simple, steady quality, and water retention property is good, and it is short to satisfy plant, long-term organic-inorganic composite fertilizer for fertile efficient, the full dose that needs.

Purpose of the present invention realizes by following technical measures:

With waste crop materials such as bar stem, blade, husk etc. a kind of or several crushed materials and poor pool as soya-bean cake, rapeseed cake, cottonseed cake, peanut cake, bean dregs, granulated slag, vinasse, vinegar a kind of or several crushed materials such as poor with any mixed except that zero after (crushed material with less than 2mm for well), mix with the water of PH4-5 again and mix thoroughly, making it hand pinches agglomerating, decontrol promptly loose, stack more than 36-72 hour, the yeast, the yeast-like fungi that utilize occurring in nature extensively to exist, effects such as cellulolytic microorganism, make it fermentation, increase organic content.Get its (dry matter) 35-45 weight, with urea ((NH ₂) ₂CO) 35～45 weight parts, monoammonium phosphate (NH ₄H ₂PO ₄) 10～15 weight parts, Repone K (KCl) 6-8 weight part and sal epsom (MgSO ₄7H ₂O) 0～0.6 weight part, lime carbonate (CaCO ₃) 0～0.6 weight part, zinc sulfate (ZnSO ₄7H ₂O) 0～0.4 weight part, copper sulfate (CuSO ₄5H ₂O) 0～0.06 weight part, manganous sulfate (MnSO ₄2H ₂O) 0～0.04 weight part, Sodium Tetraborate (Na ₂B ₄O ₇12H ₂O) 0～0.4 weight part, ferric sulfate (FeSO ₄5H ₂O) 0～0.4 weight part, ammonium molybdate ((NH ₄) ₄MO ₆O ₂₄12H ₂O) 0～0.03 weight part, sodium selenate (Na ₂SeO ₄) in 0～0.4 weight part at least three kinds (when selecting for use more than four kinds, its total content is 1.2～2.0 weight parts), behind the mixing, granulation, drying, packing are organic-inorganic composite fertilizer.

Urea in this composite fertilizer, monoammonium phosphate, Repone K are mainly done nitrogen, phosphorus, the potassium source that plant-growth needs, can do suitably to adjust according to different plants or different growing stages, for guaranteeing the quality of organic-inorganic composite fertilizer, the nitrogen content of urea is greater than 40%, monoammonium phosphate be converted into Vanadium Pentoxide in FLAKES amount 〉=35%, Repone K is converted into potassium oxide amount 〉=50% for well.Sal epsom, lime carbonate, copper sulfate, zinc sulfate, manganous sulfate, Sodium Tetraborate, ferric sulfate, ammonium molybdate, sodium selenate etc. are main for the required trace element of plant-growth, because these micro-prices are higher, plant is also few to its requirement in addition, and is therefore too much unsuitable.If above-mentioned micronutrient levels has satisfied the plant-growth needs and can not add in the soil, if above-mentioned micronutrient levels is atomic in the soil, can not satisfy the plant-growth needs, should add capacity.The blending ratio of a waste crop materials and a grease blob of slag or poor pool does not need strict measurement, adjust according to the soil fertility situation, if soil fertility is better, the proportion of dead meal can reach more than 90% weight ratio, and for the soil of poorer ridge, dead meal proportion should be reduced to below 50% weight ratio, and in most cases with dead meal: a grease blob of slag or poor pool are 0.5-0.8: 0.2-0.5 is advisable.

Because the fertilizer that the present invention adopts mainly is an agricultural waste material and a grease blob of slag, pool is pickled with grains or in wine, raw material sources are wide, do not contain objectionable impurities to plant-growth and human and livestock health, convenient transportation, agricultural waste material has bulk soil, increases the air permeability of soil, is beneficial to plant-growth, it has adsorption moisture, inorganic fertilizer, trace element simultaneously, and the effect that slowly discharges, prolong the fertilizer efficiency time, prevent that inorganics and trace element are by the rainwater washout, itself constantly discharges the nutrition that needs for plant-growth under microbial process.Production technique of the present invention is simple, and small investment of production equipment is convenient to promote.The needs that adapt to different areas soil and farm crop, a mu big area is used surplus the river east 20,000, use once with the 30-40 kilogram for every mu, the centre is dressing fertilizer no longer, increases production fairly obvious, through actual measurement, use increasing production of rice 20-30% of the present invention, corn yield increasing 15-25%, wheat increase yield 15-25%, rape yield increasing 10-15%, soil quality also has clear improvement.

Below in conjunction with embodiment, the present invention is further described:
