Formula for chemical fertilizer-biogas manure compounded fertilizer applied to cabbage planting

Abstract

The invention relates to the technical field of vegetable planting fertilizers, in particular to a formula for chemical fertilizer-biogas manure compounded fertilizer applied to cabbage planting. The formula for chemical fertilizer-biogas manure compounded fertilizer in the invention can prolong the effective period of a nitrogen fertilizer, reduce the leaching loss of a phosphate fertilizer, improve the utilization rate of nitrogen and phosphorus and fully meet the growth nutrients of planted common head cabbages in a seedling stage, a rosette stage and a heading stage, and is capable of improving the output and quality of crops. The compounded fertilizer comprises 26.42% of a chemical fertilizer, 53.58% of biogas manure and 20% of bentonite used for preparing the fertilizer into granular fertilizer via the cohesiveness of the bentonite. A ratio of total nitrogen to total phosphorus to total potassium in the fertilizer is 4.33: 2.05: 3.28; raw materials are stirred and dried according to the ratio and are then sent into a granulation system for granulation, and then the granulated raw materials are dried (wherein water content is less than 10%), so a compounded fertilizer product can be obtained; and a production process is simple and easy to implement, investment is small, an effect taking speed is high, agricultural yield is high, cost is low, wide market prospects are obtained, and good social benefits and economic benefits are achieved.

Description

technical field [0001] The invention relates to a vegetable planting fertilizer, in particular to a compound fertilizer formula for planting cabbage and biogas manure, and belongs to the technical field of agricultural fertilizers. Background technique [0002] Due to factors such as volatilization, leaching and soil fixation, the utilization rate of nitrogen fertilizer in traditional chemical fertilizers has been low. The seasonal utilization rate of nitrogen fertilizer is only 30% to 40%, and the seasonal utilization rate of phosphorus fertilizer is only about 10% to 20%. The elements are lower, and it is difficult to fully exert its effect when applied in the current season. The low utilization rate of fertilizers not only leads to poor yield and quality improvement of crops, but also reduces economic benefits, and may also cause a series of ecological and environmental problems. Through industrial means, the production of biological compound fertilizer characterized by ...
