Abstract

The invention discloses a slow controlled-release fertilizer for wheat planting on saline-alkali land. The fertilizer comprises the following raw materials by weight part: 80-100 parts of wheat straw, 8-10 parts of urea, 3-5 parts of diammonium phosphate, 2-3 parts of monopotassium phosphate, 40-50 parts of cow dung, 10-15 parts of dove excrement, 2-4 parts of probiotics stock solution and 30-40 parts of water. The chemical fertilizer is reasonably combined with the agricultural fertilizer, so that the use effect of the slow controlled-release fertilizer is better; sufficient nutrition is supplied for the planting; the wheat straw is matched with the probiotics stock solution, so that the saline-alkali land can be effectively improved; the adhesion of the soil can be increased; the planting effect can be increased.

Description

technical field [0001] The invention relates to the technical field of slow and controlled release fertilizers, in particular to a slow and controlled release fertilizer for wheat planting in saline-alkali land and a preparation method thereof. Background technique [0002] In a broad sense, slow and controlled release fertilizers refer to fertilizers whose nutrient release rate is slow and the release period is long, which can meet the needs of crop growth during the entire growth period of crops. But in a narrow sense, there are different definitions for slow-release fertilizers and controlled-release fertilizers. Slow-release fertilizers (SRFs), also known as long-acting fertilizers, mainly refer to fertilizers that are converted into effective plant nutrients at a slower rate than ordinary fertilizers after being applied to the soil. Its release rate, mode and duration cannot be well controlled, and are greatly affected by fertilization methods and environmental conditi...
