Abstract
The invention aims at providing a novel leaf fertilizer accessory ingredient. A production method of the leaf fertilizer accessory ingredient is as follows: natural nano material compounds such as straw ash in a power plant are physically and chemically modified, so that the surface hydroxyl number is increased, and dispersion performance and absorption performance are improved, the leaf fertilizer nutrient is preferably absorbed by a micro nano structure of an accessory ingredient material and fixed by a coarse plant leaf, the adhesive ability of the leaf fertilizer on the plant leaf is improved, the drifting, eluviation loss and volatilization loss are reduced, the aims of prolonging lasting period and improving the nutrient utilization are achieved. According to the method, the main raw material is natural and environment-friendly and is free from the secondary pollution; and meanwhile, the fertilization dosage and the fertilization times are reduced, the labor and the cost are saved, and the environment pollution is reduced. The technology conforms to the leaf fertilizer development direction and has great market potential.
Description
Technical field
Present method relates to a kind of production method that extends the chemical fertilizer auxiliary agent of foliage fertilizer lasting period, belongs to chemical fertilizers production field.
Background technology
Foliage fertilizer is that nutritive element is applied to farm crop blade surface and by the absorption of blade, brings into play a kind of fertilizer type of its function.Research shows, the nutritive substance that sprays application to plant surface can be absorbed by " gap " in plant leaf surface pore and stratum corneum and enters in plant materials and then be converted and utilize.The many small pores of plant leaf surface arrangement, they are also convenient to entering of nutritive substance in the function of exercising gaseous interchange, are the principal passages that plant absorbs foliage fertilizer.In addition, blade face stratum corneum is comprised of a kind of long chain fatty acid polymkeric substance with hydroxyl and carboxyl, the molecular gap of this polymkeric substance and the hydroxyl on molecule, carboxylated hydrophilic group can allow the aqueous solution penetrate in leaf, become another channel that plant absorbs foliage fertilizer nutritive substance.Leaf leaven, particularly some easily by the element of soil fixing as phosphorus, copper, manganese, iron, zinc etc., there is fast, the effective feature that absorbs, can meet in time the requirement of crop growth, can prevent and treat in time or correct again some nutritional deficiency disease or need to supply with rapidly the remedial measures of nutrient because of natural disaster.Nutrient from Foliage Absorption can directly affect internal metabolism, involved in plant metabolism, and the activity of reinforcement endoenzyme, can improve the resistance of plant, postpones leaf presenility, and can promote precocity etc.Foliage-spray both can be saved expense, can avoid again harm.Foliage-spray consumption is little, especially phosphorus, potash fertilizer and trace element fertilizer, and consumption is only the 1/10-1/5 of soil application amount, both can reduce investment outlay, the problem that also can avoid trace element fertilizer consumption too much to work the mischief.Leaf dressing and root fertilising combination, can play mutually promote, supplementary effect mutually.In a word, foliage fertilizer amount of application is few, effect is obvious rapidly, utilization rate of fertilizer is high, it is a kind of not only economic, but also fertilizer variety efficiently, particularly the reasonable interpolation of some trace elements has promoter action to plant-growth, has become the important supplementary fertilizer variety of large root fertilizer, has the larger market requirement and application prospect.
In the last few years, all take much count of production and the application of foliar nutrient both at home and abroad.The commercialization of China's foliar nutrient is since the 1980s, development through two more than ten years, the production of foliar nutrient obtains huge development, from single component, develops into composite parts, from macronutrient, develops into trace element and beneficial element, from inorganic nutrients, develop into organic nutrient, from mineral nutrient, develop into interpolation plant-growth regulator, foliar nutrient item are various, of a great variety, multifarious, the whole country approximately has thousands of kinds more than.End in May, 2007, China's foliar nutrient is formally registered 737 of products, interim registration product reaches 1398, the annual amount of application in the whole nation is about 600,000 tons of left and right, that product relates to is big or middle, micronutrient element and different organic active substances, product form has comprised the types such as solid, liquid, and product function is also different.
Yet, due to technique and technology still very unripe, foliar nutrient adhesive ability on plant leaf surface is not enough, the nutritive substance that sprays application to plant surface easily in wind, drench with rain, fly away under the effect of Exposure to Sunlight, leaching loss and volatilization, cause that fertilizer loss is serious, the lasting period is short, utilization ratio is low, need to repeatedly use, both waste a large amount of human and material resources and financial resources, cause again environmental pollution.So one of foliar nutrient industry development direction is exactly to improve blade face adhesive ability and extend the lasting period, yet about the technology of this respect, rarely has report at present.This patent provides a kind of raising foliar nutrient adhesive ability for this problem, extends the technology of lasting period.This technology mainly utilizes the micro-nano structure of natural inorganic nano material that foliar nutrient nutrient is fixed on blade face, the volatilization that reduces that it flies away, woods is become estranged, thus extended the lasting period, meet industry development direction, there is larger market potential.
Summary of the invention
The object of this invention is to provide a kind of new foliar fertilizer auxiliary agent, concrete principle is: by power plant straw ash-flyash-attapulgite-xylogen compound is carried out to physically modified and chemically modified, increase its surface hydroxyl quantity, dispersing property and absorption property, thereby foliage fertilizer nutrient is better adsorbed in promoter material micro-nano structure, and fixed by coarse plant leaf surface, thereby reach, improve the adhesive ability of foliage fertilizer on plant leaf surface, reduce and run off, extend the object of lasting period.
The present invention is achieved by the following technical solutions:
1, a production method that extends the chemical fertilizer auxiliary agent of foliage fertilizer lasting period, is characterized in that comprising the following steps:
