Hyacinth bean planting controlled-release fertilizer and preparation method thereof

Abstract

Hyacinth bean is a vegetable highly dependent on soil organic matters, long-term nutrition supply and abundant organic matters are quite pivotal, and human and animal feces are usually used for preparing fix-planting pits but easily burn seedlings if being not treated; according to the above characteristics, cow dung, pig dung and the like are firstly mixed with organic matters and are subjected to biological bacteria fermentation, then specially-prepared NPK elements are added and mixed, granulation is carried out for completing the organic fertilizer for hyacinth bean growth; the organic matters as a backing material have a long-term energy supply effect; the NPK are dissolved by resin, then are re-crosslinked in the resin through a crosslinking agent and the like and are slowly released along with resin degradation; the slow release rate is controlled through controlling the resin concentration and the crosslinking agent concentration; and the method can be adjusted according to a specific situation of hyacinth bean, reaches a controlled-release purpose, and has a great contribution in hyacinth bean high yield.

Description

Technical field [0001] The invention relates to a controlled-release fertilizer for lentil planting and a preparation method thereof, and belongs to the research field of lentil planting controlled-release fertilizer in fertilizer. Background technique [0002] Chemical fertilizers are the largest material input in agricultural production. According to statistics from the Food and Agriculture Organization of the United Nations, chemical fertilizers play a role of 40-60% in increasing yields. However, the production time shows that due to the nature of the fertilizer and the soil Due to environmental conditions and agricultural measures, the utilization rate of chemical fertilizers is very low. The waste of nutrient resources in China due to the low utilization rate of fertilizer nutrients is very alarming. According to statistics, the amount of nitrogen fertilizer produced and applied in China is about 20 million tons per year. The utilization rate of fertilizer in the current se...
