Description
Technical field
The present invention relates to the fertilizer additive technical field, relate in particular to a kind of long-acting slow-release fertilizer additive and production method thereof.
Background technology
Along with population increases and the minimizing of ploughing, and the raising of people's living standard, require agricultural constantly to increase output and improve the quality of products.Fertilizer occupies critical role in agriculture production, shared weight is more than 30% in many volume increase factors.China is chemical fertilizers production and use big country, and its output and usage quantity all occupy first place in the world, but quality product is still waiting further raising, and subject matter is that utilization rate of fertilizer is low, fertilizer efficiency period short, function singleness.Wherein the fertilizer efficiency period of nitrogenous fertilizer has only 30-50 days, and general crop need be 90-120 days the fertile phase, and the fertile phase of the fertilizer efficiency period of fertilizer and the need of crop is inharmonious, and can only taking in the agriculture production repeatedly applies fertilizer solves, and the operation of topdressing is wasted time and energy, and is extremely unbecoming with modern agriculture.Nitrogen utilization efficiency has only 30-40%, and 60-70% is by volatilization in addition, and leaching loss enters atmosphere and water body, causes serious waste and environmental pollution; The utilization ratio of phosphate fertilizer is lower, and this season utilization ratio has only about 25%.Be not difficult to find out that it is favourable to agricultural to prolong fertilizer efficiency period, can reach single fertilization, have volume increase, increase income, save fertilizer, saving of labor's comprehensive benefit; And increase operation rate not only to agricultural, particularly significant to whole national economy, have and economize on resources eco-friendly social benefit and ecological benefits.
The approach that addresses the above problem is except improving agrotechnique, and development and production long-acting slow-release fertilizer are one and get twice the result with half the effort effective measure.Existing long-acting slow-release fertilizer has three types: 1, physical: various dressings, coating, bag quilt, large-particle long-acting slow release fertilizer; 2, chemotype: urea formaldehyde, IBDU, oxamide etc.; 3, biochemical: the stable fertilizer that adds various microorganisms and biological enzyme inhibitor.All multifactor because of cost, technology etc., it is less that preceding two class slow release fertilizers are applied, and accounting for 80% long-acting slow-release fertilizer, all to belong to the biochemical long-acting slow-release fertilizer that adds inhibitor be stable fertilizer.
Existing related techniques and product have in the market: add the long-acting carbamide of urease inhibitor Resorcinol, the patent No.: 851095801; Add the long-acting ammonium bicarbonate of digestion inhibitor Dyhard RU 100, the patent No.: 901050121; With above-mentioned two kinds of inhibitor be raw material production durable composite fertilizer additive, patent No.: 99113382X.
The behavior of phosphate fertilizer in soil is different with nitrogenous fertilizer with process, and nitrogenous fertilizer mainly is that decomposition and inversion is fast, and crop has little time to absorb and volatilizees leaching loss; Phosphate fertilizer is to be easy to be fixed by soil colloid, make crop be difficult to absorb, and utilization ratio is very low.There is the plain activator of phosphorus the patent No.: 2006100461709 to occur for this reason.It is fixing that the phosphate fertilizer that is manured into soil is reduced, and can make the plain suitably activation of the phosphorus that before had been fixed in the soil, and crop is absorbed, to improve the plain utilization ratio of phosphorus.
The developing direction of fertilizer is except long-acting slow-release, and multi-functional also is an importance, has the water conservation nitrogen fertilizer potentiating agent to come out the patent No. for this reason: 031342000, and this product also has water conservation drought resisting function except having nitrogenous fertilizer synergy.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of long-acting slow-release fertilizer additive and production method thereof are provided.It has the unusual effect of long-acting slow-release and water conservation drought resisting.
