Abstract

An effective water-sucking root-growing fertility promoter and its prepn. method uses polyacrylic resin as water-sucking agent which contains plant hormone and N-P-K compound fertilizer so that the survival rate in forestation may be raised by over 20%. For prepn., the tray type instantaneous polymerization method is used with polymerization ended in 0.5-1.5 min., and at the same time, the drying procedure is dropped by utilizing its polymerization heat for moisture evaporation.

Description

High-efficiency water-absorbing rooting fertilizer and its preparing method
The present invention relates to a kind of with water-retaining agent, plant hormone and nitrogen, phosphorus, K compound fertilizer are the water-absorbing rooting fertilizer and the disc type instaneous polymerization method thereof of one, being particularly related to a kind of is water-retaining agent with the polyacrylic resin, and mixed plant hormone and nitrogen, phosphorus, K compound fertilizer are take root getting fat and disc type instaneous polymerization method thereof of the suction of one in the polymerization crosslinking process.
As everyone knows, the existing a lot of reports of the hydroscopic substance of the water-retaining agent of the polymkeric substance of high-hydroscopicity such as starch-acrylonitrile graft copolymer, starch-acrylate graft copolymer, vinylformic acid-PVA etc. and polymerization process thereof, they are used for agricultural and afforestation, make moisture preserving agent, soil improvement agent, seed pelleting etc. are obtained good effect with the water conservation for the purpose water-retaining agent.Also repeatedly occur, open clear 60-141693 as the spy and adopt the acrylic amine that contains fertilizer to make water-retaining agent at all kinds of periodicals and patent documentation.Be that methods such as the solution polymerization of adopting calipers, suspension polymerization prepare the water-absorbent superpolymer aspect polymerization, the shortcoming of these methods is that polymerization time is long, drying process, long flow path, equipment numerous and jumbled.
In addition, the effect that above-mentioned this water-retaining agent can only absorb water and protect, and plant also needs the cooperation of fertilizer such as N, P, K and root-promoting hormone or plant-growth regulator just can obtain satisfied result in process of growth except the enough water of needs, it up to this point all is the water-retaining agent that promptly adds high molecular polymer earlier that carries out respectively, adding plant hormone then refertilizes at last, operation sequence is numerous and diverse, fertilizer loss is big, apply plant hormone and fertilizer if untimely, then effect is extremely undesirable, it is also inhomogeneous to apply fertilizer, and the also high shortcoming of cost.
The object of the present invention is to provide a kind of water absurbing polymer that contains plant growth hormones, nitrogen, phosphorus, K compound fertilizer and disc type instaneous polymerization method be integrate suction, take root, the Multifucntional of getting fat absorbs water, take root, the preparation and the disc type instaneous polymerization method of getting fat.
Embodiment of the present invention are as follows, before carrying out crosslinking polymerization, vinylformic acid adds ammonium thing, potassium thing, phosphide and plant growth hormones, adding two ethylene compounds then makes linking agent and makes initiator with alkali-metal sulphite or hydrosulphite etc., under 75-85 ℃, carry out instantaneous crosslink and polymerization in general disc type polymerizer, utilize heat of polymerization that the water of polymkeric substance is formed solid with evaporation drying simultaneously, being crushed to 100 orders then just becomes water-absorbing rooting fertilizer of the present invention.
Its specifically fill a prescription (weight part) is as follows:
Vinylformic acid: 100
Compound manure: 42.5-61,
Wherein:
Ammonium thing: as ammonium hydroxide 35-50
Potassium thing: as potassium hydroxide 6.5-8
Phosphide: as Secondary ammonium phosphate, potassium primary phosphate.1-3
Two vinyl linking agents: as N, N-dimethyl bisacrylamide, N, N-dimethyl methacrylate amine, two propylene Tetraglycol 99s, two propylene, ten glycol etc.0.04-0.08
The initiator of redox system: as alkali-metal sulphite and hydrosulphite, ammonium sulphite, the reductive agent of ammonium bisulfite etc. and with alkali-metal persulphate, the oxygenant of ammonium persulphate etc. is formed.
Other initiator such as azo compound also can adopt.
Plant growth hormones is: as ABT root-inducing powder (0.06-0.09) (Chinese forest-science academy produces), growing promoter for root (0.08-0.12) (Beijing Forestry University produces).
The following examples elaborate to the present invention, but do not mean that and limit the scope of the invention.
Example 1:
Get 500 ml beakers and add 72.1 gram vinylformic acid, under agitation with 28% ammoniacal liquor, 40 grams, add 2 gram Secondary ammonium phosphates, restir slowly adds 7 gram potassium hydroxide and 1 gram growing promoter for root (Beijing Forestry University produces) down, be put in be heated to 80 ℃ in water-soluble after, add 0.05 gram N again, N-methylene-bis propylene thiamines treats that all polymerization is prepared in the dissolving back.In advance the polytetrafluoroethyldisk disk of 300 * 400 general * 25mm or polypropylene polymerization dish are put in addition and are preheating to 80-90 ℃ in the baking oven.Take by weighing 0.5 gram ammonium persulphate and 0.5 gram sodium bisulfite again, the polymerization dish taken out from baking oven set level, simultaneously the polymer fluid for preparing is taken out from the aqueous solution, rapidly ammonium persulphate and sodium bisulfite are poured in the polymer fluid, stir 3-4 after second, fall in the polymerization dish at once, begin polymerization after 10 seconds to 20 seconds, producing about 1.0 minutes post polymerization of a large amount of water vapors simultaneously finishes and forms the drying solid thing of white or brown, pulverizing behind 100 mesh sieves by analysis, its water absorbent rate is 384 times, contain N:4%, K:5%, P 2O 5, 0.4%, 1 of growing promoter for root 920 μ g/g #High-efficiency water-absorbing rooting fertilizer.
Example 2:
Operate identically, just change Secondary ammonium phosphate into potassium primary phosphate with example 1; Changing growing promoter for root into 0.05 gram ABT(China forest-science academy produces) root-inducing powder.The powder that makes its receipts water multiplying power by analysis is 355 times, contains N, 3.37%, P 2O 5, 0.14%, K: 4.35%, plant hormone is 989 μ g/g.Make 2 #High-efficiency water-absorbing rooting fertilizer.
Application examples 1:
Improve the opposite test of the surrival rate of afforestation and promotion root growth, adopt pinus sylvestris var. mongolica (biennial) to see Table 1 by the standard method test-results.
Long (cm) lateral root number (bar) root of main root amount (cm 2)
Of the present invention 1 #High-effective root-growing fertilizer synergist 21.4 17.2 6.00
Of the present invention 2 #High-effective root-growing fertilizer synergist 29.9 20.0 6.80
The acrylate water-retaining agent 20.3 14.0 5.70 of prior art
The vinyl cyanide water-retaining agent 20.3 12.0 4.38 of prior art
Contrast (blank) 18.8 11.5 2.75
As seen the high-efficiency water-absorbing rooting fertilizer of the present invention pinus sylvestris var. mongolica root system is had sprouted and promotion growth effect, and the effect that obviously is better than prior art is all arranged.
Other applicable cases and effect see also annex.
The advantage of water-absorbing rooting fertilizer of the present invention is:
1. facts have proved by the each province is large-area, show for afforestation effects such as Chinese pine, pinus sylvestris var. mongolica, larch, Chinese scholartree, willows, can on average improve survival rate and reach more than 20%.
2. compare with existing acrylonitrile water absorbing agent, well developed root system, lateral root number is many, and the volume increase income is big.
The method for making advantage of water-absorbing rooting fertilizer of the present invention is:
1. at the crosslinked front adding auxin of acroleic acid polymerization and K.P.N compound fertilizer, making like this water absorbing agent and contain equably hormone and fertilizer, play effect to improving the plant establishment volume increase, also is the fundamental difference point with prior art.
2. method for making is simple, reliable, the product quality is even.
