Description
Technical field
The present invention relates to a kind of slow-release fertilizer, relating in particular to a kind of is the slow release soil-modifying fertilizer and preparation method thereof of main raw material with the humic acids, belongs to agricultural fertilizer manufacturing technology field.
Background technology
The arable land of China accounts for 7% of the world, has but used the chemical fertilizer that accounts for the world about 35%, and fertilizer amount occupies first place in the world, and chemical fertilizer utilization ratio is low to be the subject matter that faces.Nitrogenous fertilizer is applied to very easily loss behind the soil, loss by way of drip washing, gas loss and fixing are arranged, the utilization ratio of nitrogenous fertilizer has only about 30%, a large amount of losses.The annual nitrogenous fertilizer by drip washing and volatilization loss of China causes huge waste at 1200～1,400 ten thousand tons.Potash fertilizer also can produce loss by drip washing and runoff in soil, its utilization ratio is high slightly, also has only about 35%.Fertilizer loss is except that causing waste, and serious environment pollution reduces quality of agricultural product simultaneously.Improve utilization rate of fertilizer, become extensive concern emphasis problem.
Having multiple technologies can improve utilization rate of fertilizer at present, by adding the material slow down nutrient releasing speed and fertilizer is carried out coating handle in fertilizer, is the effective means that improves the utilising efficiency of fertilizer.The subject matter of making the slow release fertilizer existence at present is that the material of cost height, interpolation exists the environmental protection risk.Chinese patent file CN1295192C (200410078165.7) wherein, CN1184173C (01133415.0), CN1218907C (02155568.0), CN1246264C (200410024049.7) is that the typical case carries out the processing of fluidized-bed coating with organic polymer material to fertilizer, make the example of sustained-controll-release fertiliser, such technological deficiency shows that mainly the production cost of fertilizer is too high, and equipment has high input and the coated fertilizer of fertilizer is not easy degraded and pollutes etc. in soil.Chinese patent file CN1491924 (02133277.0) and CN1470485 (02137991.2) are two examples that adopt the interpolation solid support material to realize the slow release of fertilizer, and its subject matter is solid support material cost height, and production method is complicated.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of humic acid slow release soil-modifying fertilizer and preparation method thereof is provided.
The present invention also provides the application of this fertilizer.
Summary of the invention
It is main raw material that the present invention adopts humic acid, xylogen and conventional NPK fertilizers, makes the slow-releasing fertilizer with the effect of improving the soil.Fertilizer of the present invention can be used for all soil types and farm crop, can improve Soil structure, improve the soil water-reataining fertilizer-keeping performance, can prevent and treat soil compaction, especially the saltings is had improved effect preferably.
