Description
Technical field
The present invention relates to water soluble fertilizer and preparation method, specifically a kind of growth encourage type stable and synergistic water soluble fertilizer.
Background technology
Along with the continuous increase of the mankind to food needs and the continuous consumption of natural resources, constantly reduce for the available cultivated area of the mankind, the manure resources that can exploit and synthesize and raw material constantly reduce, and make human needs produce more crops or cereal product on unit surface is ploughed.In order to improve unit surface crop yield, the mankind continually develop the utilization in drought soil, irrigating facility is set up in these areas and original rain-fed agriculture region, carry out the irrigable culture such as drip irrigation and sprinkling irrigation technology, adopt the Integration of Water into Fertilizer, reach the effect of province's fertilizer, water-saving, saving of labor and raising crop yield, realize the General Promotion of crop yield and quality.Along with the development of agricultural science and technology, farmland under irrigation constantly increases, it is predicted, 1,000,000,000 mu will be reached to farmland, the year two thousand twenty whole nation effective irrigation area, need water soluble fertilizer more than 2,500 ten thousand tons, this just needs to provide full nutrition, excellent property for plant growth, can stimulate plant growth, fertilizer efficiency stablizes and lasting high-quality water soluble fertilizer.Water soluble fertilizer (watersolublefertilizer,) be a kind of polyelement composite fertilizer that can be completely water-soluble, it can be soluble in water rapidly, more easily absorbed by crops, Crop utilization ratio is very high, can be applied to the irrigating facility agriculturals such as drip irrigation and spray irrigation, be realize the required unique fertilizer type of water-fertilizer integral agriculture cultivation technology.Because water soluble fertilizer and water-soluble fertilizer practice can increase substantially utilization rate of fertilizer, increase operation rate more than 1 times than Common compound fertilizer material, therefore can realize economic and reasonable fertilization, reduce significantly rate of fertilizer application, save manure resources.
Current existing water soluble fertilizer technology, there is many defects: as to comprise nutrient not comprehensive, organotrophy or organic matter can not be supplemented for crop or soil, available nutrient content is low, nutrient structure is unreasonable, balanced nutrient can not be provided for crop, after being manured into soil, effective ingredient is unstable, very easily leaching loss or volatilization loss, do not make fertilizer synergistic, the steady state of maintenance fertilizer in soil after being manured into soil, promote the effect of plant growth and enhancing crop anti-adversity to be only to provide crop institute essential nutrient element.Such water soluble fertilizer utilization ratio can not get due raising.
