Abstract
The invention, belonging to the technical filed of agriculture, relates to a water-soluble fertilizer containing humic acid chelating multielement and a preparation method thereof. The water-soluble fertilizer is formed through a chelating process of raw materials, and the component of the raw materials comprises (by weight parts): 10 potassium humate powder containing more than 50 wt% humic acid, more than 50 wt% kali and no more than 3wt% water insolubles, 48-52 water, 7-24 macroelement compound, 4-18 mediumelement compound, 7.5-23.5 microelement compound, 2.5 beneficial element compound, 2 rare earth element compound and 1.3-1.7 auxiliary agent. The preparation method includes seven steps. The water-soluble fertilizer has the advantages of complete nutrients, good compatibleness of nutrient elements, and high absorption and utilization of nutrient elements.
Description
Technical field
The invention belongs to agricultural technology field, what be specifically related to is humic acid chelating multiple element water-soluble fertilizer and preparation method thereof.
Background technology:
Water-soluble fertilizer: through water dissolution or dilution, being used for fertigation, leaf dressing, soilless culture, seed soaking dips in the liquid or solid fertilizer of the purposes such as root and is called water-soluble fertilizer (water-soluble fertilizer is defined as the NY1106-2006 of Ministry of Agriculture standard, namely " contain humic acid water-soluble fertilizer " standard 3.1 water-soluble fertilizers definition).
Leaf dressing is one of important measures of modern agricultural production.Along with development in science and technology, water-soluble fertilizer product take leaf dressing as main path develops to the multielement multifunction, contain multiple nutrient in product, the organic active additives such as humic acids, growth regulator have also been added, both can directly provide crop nutrition content, and have again stimulating growth, improve the effect of nutrition absorption.Leaf dressing has that nutrition absorption is fast, utilization rate of fertilizer is high, easy to operate, avoid some element by characteristics such as soil fixings, therefore, leaf dressing is economical and effective measures of fertilizer, obtain rapid promotion and application on agricultural production practice, become an important technique measure that improves the yield and quality in agriculture production.
At present, market provides contains humic acid water-soluble fertilizer, mainly produce according to the NY1106-2006 of Ministry of Agriculture standard (namely " contain humic acid water-soluble fertilizer " standard), although also can play certain effect during use, but have following shortcoming: the nutritive element composition is incomplete, and nutritive ingredient is relatively less; The nutritive element compatibleness is bad, and each nutritive element easily produces antagonistic action; The plant absorbing utilization ratio is low, and the shortcoming that use cost is high so research and development have the multielement water-soluble fertilizer of economical and efficient, Environmental Safety, is one of important measures of agricultural produce upgrading.
Summary of the invention
The purpose of this invention is to provide a kind of water-soluble fertilizer containing humic acid chelating multielement and preparation method thereof, this water-soluble fertilizer is that the nutritive element composition is more complete, and the nutritive element compatibleness is better, and nutritive element is by the higher water-soluble fertilizer of plant absorbing utilization ratio.
