Abstract
The invention discloses an efficient slow-release fertilizer. The efficient slow-release fertilizer is characterized by comprising, by weight, 10-15 parts of potassium humate, 5-10 parts of diammonium phosphate, 15-20 parts of urea formaldehyde and 25-30 parts of coconut shells; the potassium humate, the diammonium phosphate, the urea formaldehyde and the coconut shells are mixed with one another. The efficient slow-release fertilizer has the advantages that controllable effects can be realized, and slow-release fertilizers with different release periods can be optionally designed and manufactured in an additive quantity regulating mode; the efficient slow-release fertilizer is high in efficiency, nutrients can be released according to requirements of crops, certain quantities of nutrients can be released according to required quantities, accordingly, loss of the nutrients can be greatly reduced, and the fertilizer utilization rate can be increased.
Description
Technical field
Patent of the present invention relates to a kind of slow-release fertilizer, belongs to technical field of slow release fertilizer.
Background technology
Slow-release fertilizer refers to that chemical substance nutrient release rate is much smaller than the rate of release changing plant effective state nutrient after Quick-dissolving fertilizer is manured into soil into; Under the concept of above-mentioned slow-release fertilizer, in conjunction with the existing situation of China, constantly riseing of fertilizer price, add the farming cost of peasant, between twenty and fifty labor force leaves one's hometown and works, need repeatedly applying fertilizer a ploughing season, nobody carries out, under such national conditions, cost is lower, one cultivate only need in season once to twice slow-release fertilizer arise at the historic moment.
Existing slow-release fertilizer huge number, but all can there are some problems is as higher in price, adaptive surface is narrower, the problems such as the slowly-releasing cycle is short.Simultaneously in state-owned many areas by sky plantation, often can there is the problem of waterlogging caused by excessive rain or continuous drought, existing slow-release fertilizer does not all well control water measure, causes the fertilizer efficiency fruit of steadily releasing of slow-release fertilizer to be affected.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of advantage of lower cost, deenergized period long, by the slow-release fertilizer that soil dry humidity effect is lower, can overcome the deficiencies in the prior art.
This
contrivertechnical scheme be: slow-release fertilizer, it by following weight proportion starting material mix form, potassium humate 10-15 part, diammonium phosphate 5-10 part, urea formaldehyde 15-20 part, coconut husk 25-30 part.
The starting material mixing of the preferred following weight proportion of upper slow-release fertilizer is formed, potassium humate 10 parts, diammonium phosphate 5 parts, urea formaldehyde 15 parts, coconut husk 25 parts.
The using method of slow-release fertilizer, for doing seed manure before plant seed or seedling plantation, is spreaded manuer in holes or ditch spread.
Compared with the prior art, present invention employs the polymkeric substance urea element formaldehyde resin that urea and formaldehyde reaction obtain, also known as urea-formaldehyde resin, for white, tasteless powder or particulate state, releasing mechanism, it provides slow-release nitrogen in a kind of polymer be connected with carbon, have lower salt index, nitrogen slowly can be decomposed by water within 12 to 16 weeks, and healthy soil needs a high proportion of microorganism.Urea formaldehyde sustained-release nitrogen can be used as nutrition and energy is consumed by Institute of Micro-biology.Very the nitrogen of small proportion is supplied to plant immediately by the solvability of water, and remaining nitrogen is then decomposed by antimicrobial absorbent and discharges gradually. and this reliability and security combines, and makes urea formaldehyde sustained-release nitrogen become a kind of ideal product of applicable plant-growth.Fertilizer properties: 1, controlled: according to the regulation of fertilizer requirement of crop, can design arbitrarily by regulating the how many mode of additive and produce the slow release fertilizer of different release period.2, efficient: nutrient can discharge according to the demand of crop, and how many demands discharges how many, greatly reduces the loss of nutrient, improve utilization rate of fertilizer.3, environmental protection: nutrient scatters and disappears few to environment, involucrum fully biodegradable, environmentally friendly simultaneously.4, safety: lower salt index, can not burn seedling, hinder root.5, economical: can applied once, whole breeding time all plays fertilizer efficiency, and comparatively conventional fertilizer application can reduce consumption simultaneously, and joint is fertile, save labor force.
6, the coconut husk included can absorb the fertilizer of moisture and release when humidity is larger, slow release effect of the present invention is controlled further.
Embodiment
Embodiment 1, this slow-release fertilizer gets potassium humate 15kg, diammonium phosphate 10kg, urea formaldehyde 20kg, coconut husk 30kg mixing granulation; Using method, for doing seed manure before plant seed or seedling plantation, is spreaded manuer in holes or ditch spread.
Embodiment 2, this slow-release fertilizer gets potassium humate 10kg, diammonium phosphate 5kg, urea formaldehyde 15kg, coconut husk 25kg; Using method, for doing seed manure before plant seed or seedling plantation, is spreaded manuer in holes or ditch spread.
Embodiment 3, this slow-release fertilizer gets potassium humate 12kg, diammonium phosphate 8kg, urea formaldehyde 17kg, coconut husk 28kg; Using method, for doing seed manure before plant seed or seedling plantation, is spreaded manuer in holes or ditch spread.
Claims (3)
