The invention relates to the technical field of agricultural planting, in particular to a controlled-release bacterial fertilizer for peanuts and a preparation method of the special controlled-release bacterial fertilizer. The special controlled-release bacterial fertilizer is composed of an inner layer and an outer layer; after the outer layer is released completely, the inner-layer network structure gradually absorbs water and preserves moisture, and has good slow release and controlled release properties, thereby achieving the gradual release of the inner layer, high fertilizer utilization rate, exerting the efficacy of the microbial agent and facilitating the large-area promotion.

A composition including (a) at least one (thio)phosphoric acid triamide (T), where the (thio)phosphoric acid triamide (T) is one of N-n-butylthiophosphoric acid triamide (NBPT) and N-n-propylthiophosphoric acid triamide (NPPT), and (b) at least one specific herbicide.

A composition including (a) at least one (thio)phosphoric acid triamide (T), where the (thio)phosphoric acid triamide (T) is one of N-n-butylthiophosphoric acid triamide (NBPT) and N-n-propylthiophosphoric acid triamide (NPPT), and (b) at least one specific herbicide.

An agricultural admixture includes an acid, an organic amine, boron and one or more additional micronutrients, in which the boron and additional micronutrients are chelated, along with a saccharide. In the admixture, boron is present in an amount of at least 1.0 wt % thereof, the admixture contains a total boron and additional micronutrients content of at least 7.2 wt %, and the admixture remains stable, non-precipitated for at least 60 days. A method of spraying an agricultural admixture involves admixing the aforementioned admixture with one or more agricultural chemicals and spraying the admixture, where the admixture remains stable, non-precipitated for at least 60 days. A method of producing an agricultural admixture involves admixing the aforementioned admixture with one or more agricultural chemicals, where the admixture remains stable, non-precipitated for at least 60 days.
