摘要

This text studies coated material as the Rosin Glycerin Ester and preparation the coated -released-fertilizer, Studying the effects of soil moisture and temperature on nutrient release of coated compound fertilizer. The result shows that the temperature and soil moisture content have great influence on the total dissolution rate of rosin glyceride coated compound fertilizer; the rate of nutrient released increase with increased Of temperature and the rate of nutrient releasedincreased with increased of rate Of soil moisture and soil temperature, the accumulated nutrient released increased with increased Of rate Of soil moistureand soil temperature; There was obvious relation of line type with nutrient released period (d) and rate Of soil moisture (w). d =287.8-3.53 w, r=0.99and that of rate Of soil temperature(t) d =209.6-13t, r=0.97. The active groups of Natural Rosin are hydroxyl and conjugated double bonds, preparation of the Rosin Glycerin Ester using the Esterification of Zinc Oxinde and glycerol, Natural Rosin also has water resistance, etc. Coated Fertilizer, also know as controlled release fertilizer, common film forming material has resin, polyethylene, paraffin wax, etc[2]. The rate release of fertilizer nutrient depended on the type, dosage, the solubility of fertilizer, soil temperature and water content, and the content of microbial activity in soil, etc[3]. At present, the utilization rate of chemical fertilizer was low[4]. Due to the coated fertilizer nutrient release and crop demand for synchronization. At the same time, it has less volatilization and less leaching, so it has become a hot issue in the field of fertilizer. Fromtheexistingresearchresultsofview[5], the rate of nutrient released of coated fertilizer was measured in pure water environment, the result was not equal to the nutrient dissolution rate in soil. Therefore, key issues in this paper washow to consider the soil moisture and temperature, coated materials fertilizer factors and according to the change of soil moisture content and temperature, studied on effect on coated fertilizer on nutrient release. In this paper, by the coated compound fertilizer of the Rosin Glycerin Ester was coated material as raw material, setting different soil moisture content, soil temperature, throughpotexperiment, determination of nutrient content in coated fertilizer by mass determination, The effects of soil moisture and temperature on Kinetic characteristics of nutrient release from the Rosin Glycerin Ester coated compound fertilizer were studied, the purpose of this study was to provide scientific basis for the development and utilization of the Rosin Glycerin Estercoated compound fertilizer.
