Description
Technical field
The invention belongs to the vegetable fertilizer field, particularly, the present invention relates to be used for the release and release control fertilizer of tea tree.
Background technology
Tea big country is drunk tea, planted in China, and the tealeaves YO occupies the second in the world.Different according to plantation geographical position and kind, the tea tree tealeaves of can gathering in 1 year 2～4 times, so the supply that need in the process of growth of tea tree, keep continual nutrient supply, especially nitrogenous fertilizer just can make tea yield remain on higher level.
For this reason, someone's tea tree fertilizer that begins one's study at present.For example, Chinese patent 93102872 discloses the special-purpose fertile of tea tree blade face, and it comprises 30～55% urea, 5～20% glucose, 10～25% sylvite, 10～30% zinc salt and microbiotic etc.
More be composite fertilizer at present.For example; Chinese patent 200910016860 discloses the tea tree organic and inorganic compound fertilizer, it comprise 3～15 parts in urea, 10～30 parts in ammonium sulfate, 5～25 parts of diammonium phosphate, 5～15 parts of vitriolate of tartar and with microbial fermentation bacteria fermentation furfural dregs, scarp and differentiation matchmaker 40～70 parts of fermentation fertilizers.
But after using with apply fertilizer, especially after southern rain-belt is used, wherein the solubility inorganic fertilizer can the fast speed dissolving, has reduced the effect that fertilizer is used on the one hand, causes the fertilizer waste, also pollutes peripheral water body in addition.For this reason, there is the people to prepare slowly-releasing (controlled release) fertilizer through the mode that increases coating on the fertilizer surface.For example; Chinese patent 03128868 discloses a kind of tea tree control release composite fertilizer special; It is made up of coated carbamide and phosphorus potassium complex fertilizer; Wherein the ratio of nitrogen, phosphorus, potash fertilizer is 1: 0.2～0.5: 0.2～0.5, and coated carbamide is made up of urea, urease inhibitors, nitrification inhibitor and organic coated material.Wherein organic coated material is ROHM or urethane resin, even Plastic Resins such as urethane are buried underground, also needs to decompose decades.Therefore, in this tea tree control release composite fertilizer special, organic coated material usage is many, then is difficult to effectively discharge inner fertilizer, even causes the white pollution of Plastic Resin; And organic coated material usage is few, and soluble componentss such as the urea of infiltration are many, and then urea etc. is met dissolving rapidly behind the water, makes fertiliser granulates form vesicular or disintegration easily, and actual slowly-releasing (controlled release) ability is very limited.
And for example, Chinese patent 200710115645 discloses a kind of special controlled release fertilizer for tree plant, wherein still continues above thinking and uses thermoplastic resin, still can't solve white pollution and slowly-releasing (controlled release) hyperenergia or weak excessively problem.Especially the potash fertilizer of this patent, phosphate fertilizer and trace element do not have coated parcel, and only are to mix with thermoplastic resin membrane wrapping urea, and therefore slowly-releasing (controlled release) ability to these several constituents does not almost have.
For this reason; The inventor is through long-term and arduous research, picked out rumen-undegraded fat the existing chemical products as vast as the open sea and come Wrapped fertilizer, and the emission levels in the tea tree release and release control fertilizer of formation is moderate; And this material can degrade at occurring in nature, can not form white pollution.The 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 intravital problem of animal); And nobody uses it in the feed parcel, but the inventor finds in aqueous physical environment, can discharge with moderate speed.More unexpected is, the inventor finds that 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 parcel contains the fertilizer of yellow humic acid, only need less material just effectively to seal, reduced cost.
