Abstract
The invention provides a eucalyptus controlled release (namely slow release) fertilizer. The fertilizer comprises an outer coating layer and inner fertilizer particles in a weight ratio of (0.8-5):(5-12), wherein the fertilizer particles comprise nitrogen, phosphorus, potassium, boron, zinc and copper. In addition, the invention provides a preparation method and application of the eucalyptus fertilizer, and the like.
Description
Technical field
The invention belongs to vegetable fertilizer field, particularly, the present invention relates to the release and release control fertilizer for eucalyptus.
Background technology
Eucalyptus is fast, material is excellent, is the short period commodity trees of current Spread in China plantation, and its timber is widely used in the processing of papermaking, fibrous plate.Yet, in the process of growth of eucalyptus, the demand of nutrient is wanted to large compared with other seeds, therefore must the enough fertilizer that imposes, just can make eucalyptus normal growth.
For this reason, someone Eucalptus fertilizer that begins one's study at present.For example, Chinese patent application 03139716 discloses trace element fertilizer, comprises two or more of B, Cu, Zn, Mn, Fe and Mo element, for preventing and treating eucalyptus nutritional deficiency physiological disease.
It is at present more the composite fertilizer that inorganic fertilizer and trace element form.For example, Chinese patent application 03157602 discloses special composite fertilizer for eucalyptus, comprises that the macroelement of nitrogen, phosphorus, potassium etc. is fertile, the trace element fertilizer of iron, manganese, zinc, copper, boron, molybdenum etc., and plant-growth regulator; Chinese patent application 200510078471 also discloses fertilizer dedicated to eucalyptus material, and it is comprised of trace elements such as the macroelement such as nitrogen, phosphorus, potassium and iron, manganese, zinc, copper, boron, molybdenums; Chinese patent 200610125356 discloses fertilizer dedicated to eucalyptus, comprises 5～18% nitrogenous fertilizer, 7～15% phosphate fertilizer, 5～12% potash fertilizer, 0.05～0.3% copper, 0.05～0.4% zinc and 0.05～0.2% boron; Chinese patent application 200910166761 discloses fertilizer dedicated to eucalyptus, and Ta You city domestic sewage treatment plant mud, urea, monoammonium phosphate, Repone K form; Chinese patent application 201010585251 discloses fertilizer dedicated to eucalyptus, comprises the base manure being comprised of nitrogen, phosphorus, potassium, boron and zinc, and topdressing of being comprised of nitrogen, phosphorus, potassium, boron and the zinc of another proportioning.
Except above-mentioned composite fertilizer, the use of microbial inoculum also can increase fertility.For example, Chinese patent application 200410027047 discloses fertilizer dedicated to eucalyptus, comprises enzymatic microorganism, organic matter, humic acid, nitrogen, phosphorus, potash fertilizer etc.; Chinese patent application 200710074909 discloses fertilizer dedicated to eucalyptus, comprises the effectively viable bacteria such as yeast, actinomycetes, photosynthetic bacteria, vinelandii, P and K decomposing bacterium.But these Fertilizer application bacterial classifications are not clear, even cannot know between multiple bacterial classification, whether can produce pick up anti-.Although also there is the technology of using single culture at present, as Penicillium notatum of the bacillus megaterium of the fixed nitrogen stenotrophomonas maltophilia of Chinese patent application 200910114539, Chinese patent application 201010227376, Chinese patent application 201010548966 etc., but result of use is single, be unfavorable for practice popularization.
After above Term Fertilization, especially, after southern rain-belt is used, wherein solubility inorganic fertilizer can fast speed dissolve, and has reduced on the one hand the effect of Term Fertilization, causes fertilizer waste, also pollutes in addition periphery water body.For this reason, there is people to prepare slowly-releasing (controlled release) fertilizer by increase the mode of coating on fertilizer surface.For example, Chinese patent 96105688 discloses a kind of coated fertilizer, wherein the composition of soil layer is except 0.1～50 part of gelatin, it is mainly soluble inorganic salt, as 1～180 part of solubilizing agent (its main component is the inorganic salt such as ammonium sulfate, ammonium nitrate) and 0.1～200 part of plant nutrient compound (being mainly the vitriol of iron, zinc), cause like this in the coating of gelatin parcel and have great amount of soluble inorganic salt, after meeting water, rapid dissolving makes fertiliser granulates form vesicular or disintegration, and actual slowly-releasing (controlled release) ability is very limited.And for example, Chinese patent CN202072642U discloses the slow release compound fertilizer special for eucalyptus comprising with organic-capping layer, but the main component of organic-capping layer is polyethylene and paraffin, hard degradation own, cannot effectively discharge inner fertilizer, even cause the white pollution of vinyon.
For this reason, the inventor is through long-term and arduous research, picked out rumen-undegraded fat and carry out Wrapped fertilizer from the existing chemical products as vast as the open sea, and the emission levels in the eucalyptus controlled release fertilizer of formation is moderate, and this material can degrade at occurring in nature, can not form white pollution.Rumen-undegraded fat powder is used to wrap up the feed of animal edible in the prior art, and because it has the fusing point that exceeds envrionment temperature (this is lower than the problem in animal body), and nobody uses it in feed parcel, but the inventor finds can discharge with moderate speed in moisture physical environment.More surprisingly, inventor's discovery, this material only has under the condition of mineral manure at parcel, and encapsulation rate is not high, therefore needs more material to wrap up, and causes cost to increase; And when wrapping up the fertilizer that contains yellow humic acid, only need less material just effectively to seal, reduced cost.
Summary of the invention
The technical problem to be solved in the present invention is the Eucalptus fertilizer that provides new, and it can controlled release (that is, slowly-releasing) fertilizer.The present invention also provides and has prepared the application of Eucalptus fertilizer and method etc. in addition.
