Special organic fertilizer for broad bean planting and preparation method and application thereof

Abstract

The invention discloses special organic fertilizer for broad bean planting and a preparation method and application thereof. The organic fertilizer is prepared from, by mass, 20-35 parts of humic acid containing phosphorus larger than or equal to 3 parts and potassium larger than or equal to 3 parts, 40-55 parts of chicken barnyard manure, 5-15 parts of bean pulp, 2-8 parts of bentonite, 5-15 parts of powdery urea, 10-20 parts of Chinese cabbage, 1-10 parts of amino acid powder, 5-15 parts of Chinese herbal preparation, 1-10 parts of fermentation microflora and 1-5 parts of micronutrient fertilizer. The organic fertilizer is quick and lasting in efficiency and can inhibit occurrence of broad bean diseases, promote broad bean root development, increase the output of broad beans and improve the quality of broad beans.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a special organic fertilizer for broad bean planting and its preparation method and application. Background technique [0002] The root system of broad bean is relatively developed, and can penetrate into the soil layer 60-100cm, and the root nodules are formed earlier. The stem is square, hollow, erect, and the branching force of the stem is strong, and more than 4-5 or 8-10 branches can grow from the base. The leaves are alternate, and are even-pinnate compound leaves, the leaflets are elliptic, alternate at the base, and the apex is opposite. Flowers axillary, in racemes. Corolla purplish white or pure white. There are 2 to 6 flowers per inflorescence, and the first to second flowers generally can form pods, and the subsequent flowers have a low pod formation rate. The pods are oblate and cylindrical, and the seeds inside are hard, greenish brown or light gre...

Problems solved by technology

The solution to the latter two problems is the need for a large amount of fertilizer input. However, while increasing the yield and benefit, a large amount of fertilizer input will cause soil compaction and soil sustainability to be destroyed, which will lead to a decline in crop quality, especially a large amount of fertilizer. The production of non-renewable resources has increased the consumption of non-renewable resources, and it has also brought serious pollution to the environment.
