Abstract
The invention relates to agricultural fertilizers, and concretely relates to balanced type slow-release urea. The balanced type slow-release urea is characterized by being composed of the following compositions in percent by weight: 25-45% of urea, 15-25% of ammonium phosphate compound, 10-30% of a potassium salt, 15-35% of organic matter, 5-15% of humic acid, 0.5-1.5% of a sulfate, 0.5-1.5% of boron, 2-4% of starch, 0.05-1% of ammonium molybdate heptahydrate, and 3-5% of plastic. The balanced type slow-release urea has the slow-release and long-term release effects in farmland, the urea utilization rate is improved, high efficiency is given play under the condition of low nitrogen content, the product quality is improved, soil physical and chemical properties are improved, soil acid-base value is adjusted, actions of soil microbes are promoted, soil enzyme activity is increased, soil is loosened, soil water, fertilizer, gas and heat statuses are adjusted, plant root growth is improved, conversion speed of organic and inorganic fertilizers in soil is enhanced, plant chlorophyll is increased, plant photosynthesis is enhanced, crop stress resistance is improved, soil hardening and desertification and environmental pollution caused by excessive applying of inorganic fertilizers to soil are prevented, and the advantages of preventing plant physiological diseases and the like are provided.
Description
Technical field
The present invention relates to agrochemical, be specifically related to a kind of balanced type slow-release carbamide.
Background technology
Chemical fertilizer is widely used in agriculture production, and chemical fertilizer is soluble in water, i.e. generation effect after fertilising, and within a short period of time is absorbed by crops.Thus, in each stage of plant growth, need to apply various different fertilizer, as nitrogenous fertilizer, potash fertilizer, phosphate fertilizer etc., can not do sth. in advance to be applied to together.In addition, the amount of fertilising will adapt to, and can not execute more, otherwise can be unfavorable to plant growth.Like this, for crop, fertilizer can be caused to be applied to average weighing apparatus, namely apply fertilizer initial stage fertilizer foot, and more than absorbed dose, later stage fertilizer lacks, and is unfavorable for growth, thus needs frequent fertilising, add the workload of peasant.Further, after fertilising, if bad weather, rainwater are many, rainwater can take away fertilizer, causes waste, adds agricultural cost, and causes water pollutions.
Along with the progress of science and the development of society, earth population is in continuous increase, in order to solve the grain demand grown with each passing day, the status of development in agricultural science and technology is more and more important, and in the development of agricultural science and technology, chemical fertilizer serves vital status, but for many years with year, chemical fertilizer material in being manured into soil only has 20-30% to be utilized by this season Crop, and remaining chemical fertilizer, by soil fixing, forms a large amount of phosphoric acid salt, azotate deposition remains, destroy the crumb structure of soil, cause soil compaction, soil productivity declines, and cultivating property is deteriorated.A kind of balanced type slow release fertilizer of exploitation is badly in need of because of a little.
Above factual data illustrates, in China's agriculture production, utilization rate of nitrogen fertilizer is low, and loss is large, and fertilizer efficiency constantly declines, and agricultural product quality is degenerated, and agricultural cost increases progressively, and it has been very important problem that household income decline and ecotope constantly worsen.
Summary of the invention
The present invention, in order to overcome the above deficiency in existing fertilizer application, provides a kind of balanced type slow-release carbamide.
Technical scheme of the present invention is: a kind of balanced type slow-release carbamide, is characterized in that: be made up of following composition proportion: urea 25-45%, ammonium phosphate compound 15-25%, sylvite 10-30%, organic 15-35%, humic acids 5-15%, vitriol 0.5-1.5%, boron boron 0.5-1.5%, starch 2-4%, seven water ammonium molybdate 0.05-1%, plastics 3-5%.
A kind of balanced type slow-release carbamide, is characterized in that: described ammonium phosphate chemical combination is monoammonium phosphate or diammonium phosphate.
A kind of balanced type slow-release carbamide, is characterized in that: described humic acids be a kind of include organic matter >=60%, humic acids >=45% and the 80-120 order weathered coal that sieves.
A kind of balanced type slow-release carbamide, is characterized in that: described sylvite comprises the potassium primary phosphate of 15-20% and the saltpetre of 10-15% weight part.
A kind of balanced type slow-release carbamide, is characterized in that: described vitriol comprises the calcium sulfate of 0.3-0.9%, the magnesium sulfate of 0.1-0.3% and the zinc sulfate of 0.1-0.3%.
A kind of balanced type slow-release carbamide, is characterized in that: described plastics are the wherein one in polyacrylate compound, polyacrylamide, sodium polyacrylate.
A kind of balanced type slow-release carbamide, is characterized in that: described organic matter is organic fertilizer.
A kind of balanced type slow-release carbamide, is characterized in that: described organic fertilizer comprise at least 30% cattle and sheep chicken manure, dregs of beans, vinasse and methane slag.
Beneficial effect: from improvement soil; by increasing soil organic matter content; improve the gas permeability of soil; increase the adsorptive capacity on grogs surface; increase the adduction of various nutritive substance; nutrition protective belt can be formed rapidly at plant root after using, increase the velocity of diffusion of the nutrient such as nitrogen, phosphorus, potassium in soil and migration distance, promote root system absorbing moisture content and nutrient.Improve soil water retention, fertilizer-preserving ability, improve the water ratio of soil, play and suppress evaporation to protect earth effect, the array of growth of effective microbe in soil can be stimulated, the microbial environment of improvement soil.Promote active substance synthesis, improve crop quality.The effective outward appearance improving crop, promotes the synthesis of the nutritive elements such as amino acid, soluble sugar, VITAMIN, and reduce the harmful substance contents such as nitrate, heavy metal, agricultural-food mouthfeel is good, and fresh keeping time is long, for shelf-stable, improves commodity value.
