Abstract

The invention discloses a total-nutrient yield increasing corn fertilizer with high efficiency. The fertilizer is characterized by comprising the following components in parts by weight: 35-40 parts of urea, 10-20 parts of humic acid, 5-10 parts of itaconic acid, 10-20 parts of ammonium dihydrogen phosphate, 5-10 parts of potassium hydroxide, 10-20 parts of boric acid, 3-5 parts of zinc sulfate, 3-5 parts of sodium alginate solution and 3-5 parts of EDTA (ethylene diamine tetraacetic acid). With relatively comprehensive nutrient elements and active organic matters, the prepared fertilizer has good efficiency and strong pertinence and is quick in nutrient absorption, so that the utilization rate of the chemical fertilizer can be increased. Not only can seedling growth be promoted but also the grain number at the later stage can be increased by adopting various trace elements, so that the yield is increased and the quality is improved. A preparation method of the fertilizer is simple and practicable and has obvious economic benefits.

Description

A kind of full nutrition volume increase high efficiency corn fertilizer

Technical field

The invention belongs to technical field of fertilizers, be specifically related to a kind of full nutrition volume increase high efficiency corn fertilizer.

Background technology

Based on farm manure, chemical fertilizer is auxiliary.In China, corn major part is planted in knob, and soil layer is thin, and fertility is low, and farm manure is fertilizer mainly, and containing abundant nutritive ingredient, can improve soil, land productivity of fostering and apply fertilizer, fertilizer efficiency is longer.Chemical fertilizer is quick-acting fertilizer, although also containing the nutritive element that corn needs, compared with farm manure, and nutritive ingredient or single.Meanwhile, chemical fertilizer is in application, and also other compositions residual, are unfavorable for the growth of corn and the raising of soil fertility.For foliar nutrient, domestic market occurs a lot in recent years, is hormones mostly, is secondly mixed type.Hormones is the plant-growth regulator that with the addition of artificial chemistry synthesis, and having the function that schizophyte cell, stimulating plant grow, is useful to certain plants, but can not as broad spectrum type, and childhood, crop was not suitable for, and is more not suitable for perennial crop and crop of reserving seed for planting.Mixed type is mixing that is inorganic or organic compound mostly, add some nutritive ingredient, have production-increasing function to crop, but weak point is: most product frowziness or pungent odour, effect of increasing production is not too remarkable, performance is stable not, and fertilizer efficiency lacks of staying power, and working concentration is damage to crops not only, the power eliminating soil compaction is still deficient, disputing, it is not durable to execute postadhesion plant surface, and easily evaporate or easily run off, disease-resistant anti-adversity ability is not strong.

Trace element is that plant carries out the necessary most important element of vital movement, and be the main component forming enzyme, enzyme is a kind of protein with catalytic activity, is the metabolic important promoter of organism and attemperator.Lack them and just can not synthesize formation cell, these physiologically active substances are to the effect particularly important of crop metabolism process.Containing abundant organic substance and protein in methylene-succinic acid, and containing the necessary nitrogen of plant, potassium, photosynthesis of plant can be promoted, the also synthesis of involved in plant tumor growth element, slow to control plant-growth, leaf blight, chlorosis, the physiological disturbances such as pestalotiopsis funerea have special efficacy.

Blade is the same with root system, nutritive substance leaf is had to the feature of Selective absorber, is also a kind of approach of Crop nutritive substance.How to produce one and have comparatively full nutrition element, be equipped with active organic matter, fertilizer efficiency is good, with strong points, nutrition absorption is fast, the fertilizer of remarkable in economical benefits, be the major issue that the present invention will solve.

Summary of the invention

The present invention is in order to solve problems of the prior art, and provide a kind of full nutrition volume increase high efficiency corn fertilizer, it is characterized in that, described fertilizer components is composed as follows by weight:

Urea 35-40 part, humic acid 10-20 part, methylene-succinic acid 5-10 part, primary ammonium phosphate 10-20 part, potassium hydroxide 5-10 part, boric acid 10-20 part, zinc sulfate 3-5 part, sodium alginate soln 3-5 part, EDTA 3-5 part.

Above-mentioned one full nutrition volume increase high efficiency corn fertilizer, it is characterized in that, described method for preparing fertilizer comprises the steps:

(1) molten slurry is adjusted: with adding primary ammonium phosphate, potassium hydroxide, the molten slurry of zinc sulfate furnishing mixing after urea melting;

(2) adjust pH: melt in slurry the water adding 5 times amount to above-mentioned mixing, then be neutralized to PH=5-6 with boric acid, add sodium alginate and insert in another container and mix, under constantly stirring, add EDTA, adjust pH value to be 5-6 with sulfuric acid;

(3) mixing raw material: add humic acid in molten slurry, methylene-succinic acid stirs 40-50min, add a cover and get product for standing 24 hours.

Beneficial effect of the present invention:

The fertilizer that the present invention obtains has comparatively full nutrition element, is equipped with active organic matter, and fertilizer efficiency is good, with strong points, nutrition absorption fast, can improve chemical fertilizer utilization ratio.Contribute to the growth of Seedling root, the viscosity of cellular plasm can be improved, thermotolerance water retention capacity, and involved in sugar, protein and fat metabolism, to crop grow and various physiological process all have promoter action.Various trace elements can not only promote growth of seedling, and can increase the kernal number in later stage, thus improves output, oil recovery enhancement.Method for preparing fertilizer of the present invention is simple, remarkable in economical benefits.
