Abstract
The invention relates to a water soluble fertilizer and a preparation method, in particular to a growth-promoting stable and synergistic water soluble fertilizer and a preparation method. The water soluble fertilizer comprises the following components in percentage by weight: 10-50 percent of urea, 10-40 percent of ammonium nitrogen fertilizer, 10-30 percent of water soluble phosphorous fertilizer, 15-30 percent of water soluble potassium fertilizer, 0.5-10.0 percent of water soluble secondary elements, 0.1-8.0 percent of water soluble trace elements, 0.1-3 percent of fertilizer synergist, 0.01-10.0 percent of plant growth promoter, 0.01-10.0 percent of nitrogen stabilizer and 0-10 percent of water soluble additive, wherein the water soluble additive is a water soluble amino acid chelate and/or water soluble humic acid. The utilization ratio of the fertilizer can be increased by 60-100 percent compared with the conventional ordinary water soluble fertilizer, and the fertilizer effect can last for 120 days in maximum. Compared with an ordinary water soluble fertilizer, the growth-promoting stable and synergistic water soluble fertilizer has the advantages that the crop yield is increased by 20-60 percent by applying the same amount of fertilizer; the fertilizer can be saved by 20-40 percent at the same yield.
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, can exploit and synthetic manure resources and raw material constantly reduces, 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, set up irrigating facility in these areas and original rain-fed agriculture region, carry out the irrigable culture technology such as drip irrigation and sprinkling irrigation, 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, to reach 1,000,000,000 mu to farmland, the year two thousand twenty whole nation effective irrigation area, need water soluble fertilizer to exceed 2,500 ten thousand tons, the high-quality water soluble fertilizer that this just needs to provide full nutrition, excellent property for plant growth, can stimulate plant growth, fertilizer efficiency is stable and lasting.Water soluble fertilizer (water soluble fertilizer,) 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 to realize the essential 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 comprising nutrient not comprehensive, can not be that the supplementary organotrophy of crop or soil or organic matter, available nutrient content are low, nutrient structure is unreasonable, can not provide balanced nutrient for crop, after being manured into soil, effective ingredient is unstable, very easily leaching loss or volatilization loss, the effect that does not make fertilizer synergistic after being manured into soil, keeps steady state, promotion plant growth and the enhancing crop anti-adversity of fertilizer in soil, is only to provide crop institute essential nutrient element.Water soluble fertilizer utilization ratio can not get due raising like this.
