Definitions

  • the invention is a slow release compound fertilizer suitable for soybean planting application. It is a mixture of various fertilizers and non-specific fertilizer components containing substances that affect the nitrification of urea in the soil. Background technique
  • Soybean is an important food crop and cash crop. Its yield and acreage are second only to rice, wheat and corn, ranking fourth in the world. It plays an important role in the people's death and the national economy. In recent years, the rapid development of livestock and poultry breeding industry, the corresponding feed industry demand for soybean meal is in short supply and shortage. Effective use of limited land resources and increased yield and quality of soybean crops are the direction of efforts.
  • iron, zinc and molybdenum elements are essential micro-elements for soybean production.
  • soybean rhizobium Due to the nitrogen fixation of soybean rhizobium, a prejudice has arisen, resulting in a biased application of phosphate and potash. In fact, the growth of soybeans is a crop that requires more nitrogen. After the pre-fertility and post-fertility root tumors decline, sufficient nitrogen supply is needed, which must be achieved by fertilization.
  • Urea is a high-quality nitrogen fertilizer with high nitrogen content, fast fertilizer efficiency and large dosage.
  • urea in the process of using urea, it is easy to be lost through volatilization, leaching, decomposition and runoff, resulting in low efficiency of fertilizer efficiency.
  • the utilization rate in the current season is only about 30%, which not only causes waste of fertilizer, but also It pollutes the environment in which humans depend on the atmosphere, water and soil.
  • sulfur and various polymer resins are used at home and abroad to coat urea. Or adding a uric acid inhibitor and a nitrification inhibitor; using a high molecular polymer material such as a cyclic chlorine resin or an acrylic resin or even a multi-layer coating or a mixture of several kinds of fertilizer particles to form a slow release controlled release fertilizer; the coating material is difficult Degradation in the soil, causing damage to the soil environment. Moreover, the process is complicated, the manufacturing cost is high, and the environment is polluted.
