Abstract
The invention discloses a fertilizer nutrient controlled-release coating agent which is prepared from the following components in parts by weight: 12-17 parts of polypeptide slow-release agent, 2-12 parts of additive, 8-12 parts of white vitriol, 35-45 parts of amino acid, 4-6 parts of water-soluble silicon, 4-6 parts of sodium molybdate dihydrate, 4-6 parts of chelator, 4-6 parts of rare-earth and 4-6 parts of microelement. The coating agent has the advantages of favorable controlled-release effect, abundant fertilizer nutrients and the like, is convenient to use, and enhances the crop yield.
Description
Technical field
The present invention relates to chemical fertilizer field, the agent of a kind of fertilizer nutrition controlled release coating is provided especially.
Background technology
Fertilizer is as nutrient for plants and improve the main source of soil property, to Promoting plant growth, improves grain, fruits and vegetables output is significant.Current fertilizer mainly contains chemical fertilizer, fertilizer and bio-fertilizer.Along with the development of industrial fertilizer, people are also improving the requirement of fertilizer, so fertilizer coating technology starts to occur, although current fertilizer envelope agent has the effect of slowly-releasing fertilizer efficiency, slow release effect is still not good.
Therefore how controlled release coating agent is improved, when improving its controlled-release effect, enrich the nutritive ingredient of fertilizer, become people's problem demanding prompt solution.
Summary of the invention
Given this, the object of the present invention is to provide the agent of a kind of fertilizer nutrition controlled release coating, not good at least to solve the controlled-release effect that controlled release coating agent existed in the past, the problem that fertilizer nutritive ingredient is single.
Fertilizer nutrition controlled release coating provided by the invention agent, it is characterized in that: described coating agent is made by weight by following composition, 12 ~ 17 parts of polypeptide sustained release dosages, 2 ~ 12 parts of additives, 8 ~ 12 parts of Zinc Sulphate Heptahydrates, 35 ~ 45 parts, amino acid, 4 ~ 6 parts of water-soluble silicon, 4 ~ 6 parts of Sodium Molybdate Dihydrates, 4 ~ 6 parts of sequestrants, 4 ~ 6 parts of rare earths, 4 ~ 6 parts of trace elements.
Preferably, described coating agent is made by weight by following composition, 15 parts of polypeptide sustained release dosages, 10 parts of additives, 10 parts of Zinc Sulphate Heptahydrates, 40 parts, amino acid, 5 parts of water-soluble silicon, 5 parts of Sodium Molybdate Dihydrates, 5 parts of sequestrants, 5 parts of rare earths, 5 parts of trace elements.
Further preferably, described additive consists of by weight following composition: 40 ~ 50 parts, sulphur, 30 ~ 40 parts, paraffin, 6 ~ 10 parts, sterilant, bright blue 5 ~ 10 parts.
Further preferably, described polypeptide sustained release dosage consists of by weight following composition: 6 ~ 10 parts of Dyhard RU 100s, 3 ~ 5 parts of Resorcinol, 44 ~ 55 parts, zeolite, 30 ~ 50 parts of humic acidss.
Further preferably, described sequestrant is hydroxy ethylene diphosphonic acid.
Further preferably, described trace element is calcium or copper and composition thereof.
The preparation method of this fertilizer nutrition controlled release coating agent is that mentioned component dissolves mixing, during use, be wrapped in fertilizer surface and just can be reached the effect of slowly-releasing, traditional Bulk Blending Fertilizer only contains nitrogen, phosphorus, three kinds of elements of potassium, can only maintain the basic nutrient of plant growth.If wrap the agent of nutrition controlled release coating in Bulk Blending Fertilizer, just can greatly improve the absorption of crop to nutrient, sufficient trace element can supplement that the growth in crop each period is required, and sustained release dosage can be controlled nutrient and discharge by stages, and time and labour saving is laborsaving.Trace element wherein can improve the chlorophyll content of plant, strengthens photosynthesis, promotes root system development, increases root system to nutrition absorption.Can also promote seed germination, improve rate of emergence, promote growth of seedling.Except above Main Function, also have and make some crop strengthen ability disease-resistant, cold-resistant, drought resisting.
Fertilizer nutrition controlled release coating provided by the invention agent, has controlled-release effect good, easy to use, enriches fertilizer nutritive ingredient, improves the advantages such as crop yield.
